I suspect it is an issue for Mac OS X versions below which we provide build bots. Everything Snow Leopard and up had a clean build.

Apparently only on Tiger (also Leopard? not sure). On 10.6.8 and 10A190 Apple gcc-4.2 builds it fine, so it is not a compiler issue per se.

comment:5 Changed 19 months ago by kencu (Ken)

there are many examples (ruby, cctools, more) of the signal.h header causing issues on the transition for Tiger -> Leopard because the register naming changed.

So it's probably that again, but someone with Tiger will have to spend some time and take a look.

Same issue with coreutils @9.3 on Tiger:

:info:build /usr/include/sys/signal.h:177: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'ucontext64_t'

gcc 7 and clang-mp-3.4 give an unknown type name '__darwin_mcontext64_t' error instead.

mcontext64_t is defined like this in sys/signal.h: 

#ifndef _POSIX_C_SOURCE
#ifndef _MCONTEXT64_T
#define _MCONTEXT64_T
typedef __darwin_mcontext64_t       mcontext64_t;
#endif
#endif /* _POSIX_C_SOURCE */

__darwin_mcontext64_t is defined like this in sys/_types.h: 

#ifndef _POSIX_C_SOURCE
typedef struct mcontext *__darwin_mcontext_t;   /* [???] machine context */
typedef struct mcontext64 *__darwin_mcontext64_t; /* [???] machine context */
#else /* _POSIX_C_SOURCE */
typedef struct __darwin_mcontext *__darwin_mcontext_t; /* [???] machine context */
#endif /* _POSIX_C_SOURCE */

I can reproduce the problem with this simple C source: 

#define _POSIX_C_SOURCE 200112L
#include <sys/types.h>
#undef _POSIX_C_SOURCE
#include <sys/signal.h>

gnulib commit ​b1d7d87c ("stdio: suppress macOS 13 sprintf warnings") from March 5th performs a similar define/undef so I bet that's the problem. The OS X 10.5 SDK from Xcode 3.1.4 looks immune to this because it uses a __need_mcontext64_t macro and defines the types in architecture-specific headers.

gnulib considers OS X 10.4 to be a "formerly supported platform", so I'm not sure if this is a valid upstream issue.

grep 3.10 builds without any trouble on Tiger i386: 

$ port -v installed grep
The following ports are currently installed:
  grep @3.10_0 (active) requested_variants='' platform='darwin 8' archs='i386' date='2023-04-28T21:43:12-0700'

I didn't try PPC yet.

Summary: grep @3.10 is broken on Tiger: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'mcontext64_t' → grep @3.10 is broken on some versions of Tiger (?PPC ONLY): error: expected '=', ',', ';', 'asm' or '__attribute__' before 'mcontext64_t'

comment:9 Changed 19 months ago by kencu (Ken)

Installing coreutils on Tiger i386 does fail as mentioned, but also as mentioned, it seems to be missing the definitions in <sys/types.h>. I just hacked in an #include <sys/types.h> into the end of lib/config.h and coreutils built.

But that should be a separate ticket.

comment:12 Changed 18 months ago by ballapete (Peter "Pete" Dyballa)

#67488 has the same problem. Is it necessary to try building more than once or twice? The environment in which I try to upgrade changes from try to try because gtk3 (depending on libxkbcommon/libxkbcommon-x11 ) and poppler do not upgrade, so I have to reset the version number or remove lines inside their Portfiles…

The pre-compiled output has: 

# 128 "/usr/include/sys/signal.h" 3 4
#define SIG_DFL (void (*)( ))0
#define SIG_IGN (void (*)( ))1
#define SIG_HOLD (void (*)( ))5

#define _MCONTEXT_T 
typedef __darwin_mcontext_t mcontext_t;

# 160 "/usr/include/sys/signal.h" 3 4

#define _UCONTEXT64_T 
typedef __darwin_ucontext64_t ucontext64_t;
# 186 "/usr/include/sys/signal.h" 3 4

The types used are not defined in this scope. I think sys/ucontext.h needs to be included that has #include <machine/ucontext.h> which has a switch: 

#ifndef	_MACHINE_UCONTEXT_H_
#define	_MACHINE_UCONTEXT_H_

#if defined (__ppc__) || defined (__ppc64__)
#include "ppc/ucontext.h"
#elif defined (__i386__) || defined(__x86_64__)
#include "i386/ucontext.h"
#else
#error architecture not supported
#endif

#endif	/* _MACHINE_UCONTEXT_H_ */

Could be a configure.cppflags-append -include sys/ucontext.h helps to cure the problem…

comment:16 Changed 18 months ago by Cebtenzzre

ballapete, see my earlier comment. From what I can tell it's not a missing header, as the necessary types should be provided by sys/_types.h. It's caused by e.g. gnulib #undef'ing a feature test macro (_POSIX_C_SOURCE) and fragile preprocessor conditionals in the system headers.

comment:17 Changed 18 months ago by ballapete (Peter "Pete" Dyballa)

This is not easy to believe – GCC7 is one and a half years old, apple-gcc42 that was used for wget, is two and a half years old. The failures are too recent.

As long as other ports are being built I can check whether and where this macro gets processed.

which means that _POSIX_C_SOURCE is (was) #defined. Actually the problem is despite types __darwin_mcontext64_t and __darwin_ucontext64_t #defined. These are defined outside of sys/_types.h, in sys/signal.h:

Which means that in-between _POSIX_C_SOURCE changed to being undefined…

First time here: 

# 21 "./stdio.h" 3
# 42 "./stdio.h" 3
#define _POSIX_C_SOURCE 200809L    (line 2406 pre-processed output)

then 

# 50 "./stdio.h" 2 3

#undef _GL_ALREADY_INCLUDING_STDIO_H


#undef _GL_DEFINED__POSIX_C_SOURCE
#undef _POSIX_C_SOURCE



#define _GL_STDIO_H 
# 68 "./stdio.h" 3                (line 2924 pre-processed output)

And indeed some 2,000 lines later sys/signal.h with the user context variables gets included. So it's stdlib.h that resets the macro?

I tried to build texinfo with GCC7 and it failed this way: 

In file included from /usr/include/sys/wait.h:110:0,
                 from /usr/include/stdlib.h:64,
                 from ./stdlib.h:36,
                 from error.c:29:
/usr/include/sys/signal.h:145:9: error: unknown type name '__darwin_mcontext64_t'
 typedef __darwin_mcontext64_t  mcontext64_t;
         ^~~~~~~~~~~~~~~~~~~~~
/usr/include/sys/signal.h:177:9: error: unknown type name '__darwin_ucontext64_t'
 typedef __darwin_ucontext64_t  ucontext64_t;
         ^~~~~~~~~~~~~~~~~~~~~

This makes the situation clear: there are no 64-bit process contexts on G3 and G4 and i386. I found ​this which deals with 64-bit support for RTEMS running on G4, I think. Maybe it's easier to add 32-bit support to `gnulib…

@Cebtenzzre -- you nailed it.

I think (sadly) this will need a port-by-port fix as I can't see an elegant way to throw it into legacysupport. Maybe someone else can.

I had this issue with gnutar on 10.4 PPC as well, which was a circular dependency problem, as I needed to build automake, which is when I found that the system tar was too old to extract automake, but gnutar also depended on automake.

I just ended up building the newest version of tar that I could (1.30), and then forcing macports to use it by creating a symlink from /usr/bin/tar to my manually compiled tar in /opt/local. I'm sure that's not the recommended way to do things, but it seems to work fine.

Note: See TracTickets for help on using tickets.
