My Portfile has two interesting ranges:

    148 # just use the ones internal to cmake instead.
    149 platform darwin 8 {

    158         port:libarchive \
    159         port:ncurses
    160 }

and

    173 platform darwin {

Oh, this is a different error, Michael. Peter is building this with gcc6 already, which supports c++11. This issue is a Tiger header thing. That statement should fix it.

The pre-processor produces this code:

int uv_os_unsetenv(const char* name) {
  if (unsetenv(name) != 0)
    return -
# 1293 "Utilities/cmlibuv/src/unix/core.c" 3 4

                ;

  return 0;
}

uv_os_unsetenv() is declared in

Utilities/cmlibuv/include/uv.h:UV_EXTERN int uv_os_setenv(const char* name, const char* value);
Utilities/cmlibuv/include/uv.h:UV_EXTERN int uv_os_unsetenv(const char* name);

They both overwrite the system's declarations.

In the pre-processed output I find

int setenv(const char *, const char *, int) ;
...
void unsetenv(const char *);
# 260 "/usr/include/stdlib.h" 3 4

coming from

int	 setenv(const char *, const char *, int) __DARWIN_ALIAS(setenv);
...
#if __DARWIN_UNIX03
int	 unsetenv(const char *) __DARWIN_ALIAS(unsetenv);
#else /* !__DARWIN_UNIX03 */
void	 unsetenv(const char *);
#endif /* __DARWIN_UNIX03 */

in /usr/include/stdlib.h. And cmake-3.10.0/Utilities/cmlibuv/src/unix/core.c has

 1280	int uv_os_setenv(const char* name, const char* value) {
 1281	  if (name == NULL || value == NULL)
 1282	    return -EINVAL;
 1283	
 1284	  if (setenv(name, value, 1) != 0)
 1285	    return -errno;
 1286	
 1287	  return 0;
 1288	}
 1289

 1295	  return 0;
 1296	}

OK. Thanks for trying. For now, I'd suggest you can peg at cmake 3.9.6 - it should work for many years to come. If you can sort out how to to fix this, that would be great! Otherwise I will dig into this error in due course on my Tiger machine.

comment:9 Changed 7 years ago by kencu (Ken)

I tried various things to fix this, but it's not as easy as the usual #define __DARWIN_UNIX03 fix. When you turn that on, other configuration things fail.

At the moment, changing the file

Utilities/cmlibuv/src/unix/core.c

to edit the way unsetenv is called seems most likely to work.

comment:11 Changed 7 years ago by kencu (Ken)

That's a good start.

One thing to ponder is how did cmlibuv build on Tiger in cmake 3.9.6, and could we use that to figure out how to make it build in 3.10.0; or maybe just steal the whole cmlibuv from 3.9.6 and use that in 3.10.0 on Tiger?

Maybe we could just diff the two folders (cmlibuv) and see what has changed to break it in 3.10.0.

I looked at the use of *birthtime*. It only happens with archives (Cmake brings its own libarchive). Tiger has archive_entry.h which has the birthtimes declared. So the problem with birthtime not found in struct stat might be solved with the provided second patch file, patch-birthtime@Tiger.diff. At least fs.c gets now compiled. But a new error now happens:

Just a missing #include <sys/socket.h>?

I did not perform a diff on directories, just grepped for *birthtime*. The more accurate comparison of the two software versions I might perform some other day. (Or night.)

Proposed patch for Tiger's unknown birthtime

comment:13 Changed 7 years ago by kencu (Ken)

getting there!

man sendfile says:

HISTORY
     The sendfile() system call first appeared in Darwin 9.0 (Mac OS X version
     10.5) .

so it will have to be reimplemented for Tiger.

comment:14 Changed 7 years ago by kencu (Ken)

Summary: cmake @3.10.0 does not build on PPC Tiger, Mac OS X 10.4.11, because error: void value not ignored as it ought to becmake @3.10.0 does not build on PPC Tiger, Mac OS X 10.4.11, due to various issues building libuv

comment:15 Changed 7 years ago by kencu (Ken)

we might be able to get an implementation of sendfile from here <https://elixir.free-electrons.com/linux/v3.10/source/fs/read_write.c>.

I wish I knew how to use autotools well enough to see how to get it to give us up a replacement function automatically. Edit: gnulib-tool does not have a replacement for sendfile, I suppose because it is implemented in the kernel and only referenced as a function definition in the headers and sources.

Replying to kencu:

That's a good start.

One thing to ponder is how did cmlibuv build on Tiger in cmake 3.9.6, and could we use that to figure out how to make it build in 3.10.0; or maybe just steal the whole cmlibuv from 3.9.6 and use that in 3.10.0 on Tiger?

Maybe we could just diff the two folders (cmlibuv) and see what has changed to break it in 3.10.0.

These are the changes (cmake-3.10.0/Utilities/cmlibuv/src/unix/cmake-bootstrap.c ist a new file, possible related to the macro CMAKE_BOOTSTRAP):

well, if you're feeling lucky, you might just whack that whole thing in as a giant patch (with the right patchlevel sorted out) and see if it "just works" after that.

Kind of resetting CMake's own version ob libuv leads to an error:

just inherently defined and used… The type of uv_once_t is defined as:

typedef pthread_once_t uv_once_t;

Which can be resolved in steps to:

typedef __darwin_pthread_once_t pthread_once_t;
typedef struct _opaque_pthread_once_t
   __darwin_pthread_once_t;
struct _opaque_pthread_once_t { long __sig; char __opaque[4]; };

I've taken this from the pre-processed file. *I* have no idea why GCC 6 sees here an int.

comment:20 Changed 7 years ago by kencu (Ken)

Summary: cmake @3.10.0 does not build on PPC Tiger, Mac OS X 10.4.11, due to various issues building libuvcmake @3.10.1 does not build on PPC Tiger, Mac OS X 10.4.11, due to various issues building libuv

comment:21 Changed 7 years ago by ballapete (Peter "Pete" Dyballa)

CMake's Portfile has for El Capitan, or all Darwin versions, the configure option --system-libs (line # 152). This is withdrawn for Tiger (line # 152). Couldn't this be as well used for Tiger, in case libuv could be built on Tiger? (See #53143 and #55594)

comment:22 Changed 7 years ago by ballapete (Peter "Pete" Dyballa)

I started a request on the libuv mailing list to enhance the code in order to handle the special Tiger case.

comment:23 in reply to:  2 ; Changed 7 years ago by ballapete (Peter "Pete" Dyballa)

Replying to kencu:

try adding this and please report back

# fix build on Tiger
if { ${os.platform} eq "darwin" && ${os.major} == 8 } {
    configure.cxxflags-append -D__DARWIN_UNIX03
}

I started to test again, since this libuv failure makes upgrading the ports a bit complicated. Portfilehas already

    166 platform darwin 8 {
    167     configure.args-delete --system-libs
    168     configure.args-append --no-system-libs

so one can add

    169     configure.cppflags-append -D__DARWIN_UNIX03

but this change leads to exactly the same build failure, no change. So it's likely that the function using unsetenv{} needs a fix.

In #55145 this fix for Kerberos is featured:

-    if (unsetenv(KRB5_ENV_CCNAME) != 0) {
-        retval = errno;
-        com_err(prog_name, retval, _("while clearing the value of %s"),
-                KRB5_ENV_CCNAME);
-        return retval;
-    }

In Tiger the if clause compares a void() with an integer. If the compiler accepts this type mismatch then the result must be true – something (undefined?) will almost never equal 0. So the code block is entered. Where comes errno from? Does it need (local, inside the function) declaration? Or is there some automatism at work?

The original funtion in cmake-3.10.0/Utilities/cmlibuv/src/unix/core.c is:

int uv_os_unsetenv(const char* name) {
  if (unsetenv(name) != 0)
    return -errno;

  return 0;
}

which looks quite similar, and the error repored by GCC 6 is:

error: void value not ignored as it ought to be

I presume this report will continue to exist…

comment:24 in reply to:  23 Changed 7 years ago by ballapete (Peter "Pete" Dyballa)

Now, this is fascinating! Using

    169     configure.cflags-append -D__DARWIN_UNIX03

instead of

One problem solved, another one gained! (A least.) But patches exist! They just need a bit adjustment to __DARWIN_UNIX03, don't they?

comment:25 in reply to:  23 Changed 7 years ago by ballapete (Peter "Pete" Dyballa)

Replying to ballapete:

Replying to kencu:

The original funtion in cmake-3.10.0/Utilities/cmlibuv/src/unix/core.c is:

int uv_os_unsetenv(const char* name) {
  if (unsetenv(name) != 0)
    return -errno;

  return 0;
}

Isn't the following equivalent?

int uv_os_unsetenv(const char* name) {
  unsetenv(name);
  /* in old libc (Mac OS X 10.4) unsetenv() returns void, so let's check success "manually" */
  if (getenv(name) != NULL)    /* name still exists in environment */
    return -errno;

  return 0;                    /* successful elimination */
}

So the improved patch (who knows all side effects of #defining __DARWIN_UNIX03?) would be:

 int uv_os_unsetenv(const char* name) {
+#if __MAC_OS_X_VERSION_MIN_REQUIRED >= 1050
   if (unsetenv(name) != 0)
     return -errno;
-

Hi Peter,

I did get a slightly older version of libuv, 1.7.5 to build through to completion on Tiger PPC. I thought I would start there with something a bit simpler. I'm not sure if it's new enough to support cmake, but perhaps this is a start at least.

Most of the tests pass. There are some very smart people around here, like Michael for example, who might be able take this one to the end zone.

Here's the patch I used for libuv 1.7.5: <https://github.com/kencu/TigerPorts/commit/55ef4b50b05d1c8fbc37bb9f613f4e396e463827>

And here's the whole Portfile with patches:

<https://github.com/kencu/TigerPorts/tree/master/devel/libuv>

Best, Ken

Replying to kencu:

try adding this and please report back

# fix build on Tiger
if { ${os.platform} eq "darwin" && ${os.major} == 8 } {
    configure.cxxflags-append -D__DARWIN_UNIX03
}

Ken, are you sure this works? Recently I had to use configure.cflags-append -D__DARWIN_UNIX03 to see a difference, i.e. the cure of void unsetenv(). Can it be this works only when invoking port test <some port>?

I think of recording all the C header files (via configure.cflags-append -H) and then finding all the source files that use a header with __DARWIN_UNIX03 to possible determine all the changes that are introduced through this definition.

BTW, I think I have found a *fully* compatible version for the unsetenv() problem:

int uv_os_unsetenv(const char* name) {
  /* Mac OS X before Leopard, 10.5, has void unsetenv */
#if __MAC_OS_X_VERSION_MIN_REQUIRED > 1040
  if (unsetenv(name) != 0)
    return -errno;

#else
  unsetenv(name);
  if (getenv(name) != NULL)    /* if name still exists in environment, then no NULL pointer */
    return -1;
#endif

  return 0;
}

The only question left, for me, is whether 1 is the correct value… I mean the value for errno, if used here, would be that of getenv(). Which error could happen? A typo in name? No memory or disk space left? But it seems to that this function is just declared (for UNIX and MS) and nowhere used. So it could be removed as well.

comment:28 in reply to:  27 Changed 7 years ago by ballapete (Peter "Pete" Dyballa)

Only seven C header files use __DARWIN_UNIX03:

/usr/include/assert.h
/usr/include/stdio.h
/usr/include/stdlib.h
/usr/include/sys/cdefs.h
/usr/include/sys/errno.h
/usr/include/time.h
/usr/include/unistd.h

Yes. I used them as potential input against the errors that appeared (approximately two). Without explanation it's not easy to decide which patch cures which error. Besides, I am working on CMake 3.10.3 meanwhile. Could be some of them are not necessary.

My guess here is that g++-mp-6 can't find /opt/local/lib/libstdc++.6.dylib in -isysroot /Developer/SDKs/MacOSX10.4u.sdk Try a quick hack like this, to link in /opt/local to the SDK so it can find it. (or figure out how to change the -isysroot to "/".

but in the end the result is the same. Why is -isysroot necessary at all? Doesn't the compiler know by heart where its guts can be found?

And I have Tests/CMakeTests/ImplicitLinkInfoTest.cmake.in. It has a Mac section, although it uses GCC 4.2.1 for PPC related tests. In its Linux section the GCC invocations with -lgcc_s while in the MS WIndows section it's -lgcc_s.1. So there must be a file that dictates which tests are performed on Tiger at build time, where -lgcc_s can be substituted with -lgcc_s.1.

/Developer/SDKs/MacOSX10.4u.sdk/usr/lib/libgcc_s.10.4.dylib has a strange attraction – still no success with std::unique_ptr

comment:39 Changed 6 years ago by michaelld (Michael Dickens)

Summary: cmake @3.10.1 does not build on PPC Tiger, Mac OS X 10.4.11, due to various issues building libuvcmake 3.10-12 does not build on PPC Tiger, Mac OS X 10.4.11

has duplicate #57551 ... which does have some relevant info in it ... but there's at least as much relevant info here ... so we're keeping this one

comment:40 Changed 6 years ago by kencu (Ken)

for the foreseeable future you'll need to peg cmake in Tiger at 3.96.

I have libuv 1.9.1 building on Tiger now. That's up from 1.7.5. So might get there one day...

comment:41 Changed 6 years ago by kencu (Ken)

cmake needs (presently) libuv 1.10.0 and I have 1.9.1 building, so we're close. I have thought of a different idea as well that might solve this...stay tuned.

comment:42 Changed 6 years ago by kencu (Ken)

Well, it is possible to do it:

$ port -v installed cmake
Warning: port definitions are more than two weeks old, consider updating them by running 'port selfupdate'.
The following ports are currently installed:
  cmake @3.12.3_0 (active) platform='darwin 8' archs='i386' date='2018-11-10T12:09:44-0800'

$ cmake --version
cmake version 3.12.3

CMake suite maintained and supported by Kitware (kitware.com/cmake).

Just have to automate it now...

Pretty good, eh? There are a couple of test suite failures I'd like to fix (or like someone to help me fix), but it works quite well. I told you I'd get it done ;>

cmake for 10.4 is fixed as well <https://github.com/macports/macports-ports/pull/3012>. Mike is just wanting to wrap around the fix and see if it is as good as it can possibly be.

IF you're impatient (dunno why -- cmake-3.9 builds everything still, and you have that now) but if you are impatient, it's not too hard to check out the PR and build it for yourself.... Go for it! Or wait until Mike commits / says we can commit it.
