clang-11-bootstrap @11.1.0_4: Attempting to use @rpath without CMAKE_SHARED_LIBRARY_RUNTIME_C_FLAG being set

[Cebtenzzre]

The clang-11-bootstrap port, which seems to be required to build libcxx and any version of clang newer than 3.4, still doesn't build on Tiger. Here's the current failure:

Cebtenzzre, I've supprised that it tries to use rpath.

May I ask you to share with me the whole cmake configuration output which includes its call by line like

clang-11-bootstrap/clang-11-bootstrap/work/build" && /opt/local/libexec/cmake-bootstrap/bin/cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX="/opt/loca...

clang-11-bootstrap will probably never build on Tiger.

It will take some serious effort to get it to do so, and nobody has done that as yet.

[kencu (Ken)]

Even then, it is completely useless on Tiger PPC, and we are talking about a long shot at getting it build on Tiger Intel (which almost nobody cares about anyway, to be honest).

[kencu (Ken)]

libcxx doesn't build on Tiger, and (I believe) no clang newer than clang-3.4 builds on Tiger either using MacPorts current Ports tree.

(Now -- it is possible to get farther. I have libcxx 5.0 built for Tiger, and clang-3.7, 3.8, 5.0, and 7.0 on my Tiger i386 system. But it took ungodly serious hacking to get it to build, and as it only worked on i386, and imperfectly there, and is useless for both building on PPC or building PPC software that might run on PPC, I never pushed it to MacPorts as there would just be 1,000 tickets about all the imperfections).

[catap (Kirill A. Korinsky)]

May I ask you to test ​https://github.com/catap/macports-ports/tree/clang-11-bootstrap ? It is a kind of blind shot.

[kencu (Ken)]

If you would like to have a go at building clang-anything on Tiger i386, Tiger Server works in a VirtualBox VM with some small tweaks.

You really won't get anywhere with blind shots, although I appreciate your enthusiasm, you'll just drive the poor ticket reporter crazy.

[Cebtenzzre]

That fix appears to have worked, now it successfully configures but fails to build. Should I open a new ticket?

I just pushed updated version of patch. I guess we may continue to use this ticket.

[Cebtenzzre]

Now that issue is resolved, but there are more errors:

Cebtenzzre, I've just pushed one more things that may help. I really haven't tested it, so, it may not work at all :)

[Cebtenzzre]

Better, but there are still problems. I'm running into #67360 for all attempts to use gcc 10, plus these compiler errors (I ran make with --keep-going this time):

[catap (Kirill A. Korinsky)]

I've pushed an updated version which addresses the issues in the first block.

The second part is puzzling me. From provided configure output:

729	:info:configure -- Looking for pthread_create in pthread
730	:info:configure -- Looking for pthread_create in pthread - not found
731	:info:configure -- Looking for pthread_create in c
732	:info:configure -- Looking for pthread_create in c - not found

I may conclude that pthread isn't available or available in some strange way because base on ​https://github.com/phracker/MacOSX-SDKs/blob/master/MacOSX10.4u.sdk/usr/include/pthread.h it should be good enough to run it.

As soon as that blocks in llvm/cmake/config-ix.cmake:85 decides that you have good enough pthread it should be fine. It runs check_library_exists(pthread pthread_create "" HAVE_LIBPTHREAD) and based on provided configure output it can't find anything inside library.

May I ask you to add into configure.args inside portfile --debug-output or --trace (will provides really a lot). It may explain this.

[Cebtenzzre]

CMakeError.log shows why pthread_create was not found:

Determining if the function pthread_create exists in the pthread failed with the following output:

A quick google search tells me this could be due to missing -fPIC.

[catap (Kirill A. Korinsky)]

Pushed an update which contains enforcing -fPIC, may I ask you to try it?

[Cebtenzzre]

-fPIC is in the flags now, but the linker still fails:

/opt/local/libexec/gcc10-bootstrap/bin/gcc -pipe -fPIC -DNDEBUG -DCHECK_FUNCTION_EXISTS=pthread_create -arch i386 -mmacosx-version-min=10.4 -Wl,-search_paths_first -Wl,-headerpad_max_install_names -static-libstdc++ -static-libgcc  CMakeFiles/cmTC_999e1.dir/CheckFunctionExists.c.o  -o cmTC_999e1 -lpthread

And this is a build error I didn't notice before because I had my PATH set wrong:

[catap (Kirill A. Korinsky)]

Are you running it via port or by hand?

[Cebtenzzre]

I've been testing the build via port, and then re-running make by hand with --keep-going in order to make sure I'm seeing all of the build errors. Let me know if you think there's a better way to do that, I'm not familiar with Portfile syntax. (edit: I figured out build.args, I'll use that from now on.)

[catap (Kirill A. Korinsky)]

Replying to Cebtenzzre:

I've been testing the build via port, and then re-running make by hand with --keep-going in order to make sure I'm seeing all of the build errors. Let me know if you think there's a better way to do that, I'm not familiar with Portfile syntax.

This port file are quite sensetive for something wired in PATH like MacPorts' cctools :)

May I assume that you've picked the error from ​https://trac.macports.org/ticket/67348?replyto=17#comment:13 via port? May I ask you to run port clean clang-11-bootstrap and port configure clang-11-bootstrap and share with me port's log and cmake's error files.

Thanks.
