PPCG does not build well on Ubuntu 24.04 LTS

[alex....@gmail.com]

  Hello.

    I have an Ubuntu 24.04 LTS installation, with clang and llvm version 18.1.3.

    I cloned today the PPCG source code from git://repo.or.cz/ppcg.git. I followed the instructions from the README. Everything works OK until I give make, which fails with the following error:

  <<extract_interface.cc:413:41: error: no matching function for call to ‘clang::SourceManager::createFileID(const clang::FileEntry*&, clang::SourceLocation, clang::SrcMgr::CharacteristicK
ind)’
        413 |         SM.setMainFileID(SM.createFileID(file, SourceLocation(),

      /usr/lib/llvm-18/include/clang/Basic/SourceManager.h:911:36: note:   no known conversion for argument 1 from ‘const clang::FileEntry*’ to ‘clang::FileEntryRef’>>

    Did anybody else encounter this error?

    I changed the file extract_interface.cc and was able to get past this error, but another error appeared:

  <<extract_interface.cc: In function ‘void set_lang_defaults(clang::CompilerInstance*)’:
    extract_interface.cc:441:29: error: ‘setLangDefaults’ is not a member of ‘clang::CompilerInvocation’
        441 |         CompilerInvocation::setLangDefaults(Clang->getLangOpts(), IK_C,>>

    I'm currently trying to fix this error.

    Any help is appreciated.

  Thank you,

     Alex

Hi Alex,

FWIW: LLVM maintains an Ubuntu repository with different versions of LLVM. You may find it easier to use, instead of distro-provided Clang: https://apt.llvm.org/ Since clang-18 appears to be incompatible with PPCG, it's worth trying clang-17 from LLVM repo.

Kind regards,

Dmitry.

I have created a patch for this problem, https://github.com/lijinpei/isl-mirror/commit/b40431550f8352fb0a72629f3f811081b061dfc7 , but I don't know how to get it reviewed/submitted.

You should post it here.
Note that I have been working on a fix myself,
which should be out soon.

I noticed pet also has this problem, besides it uses clang::ArrayType:Static, which has been moved to another place in llvm-18. I created a patch for this problem https://github.com/lijinpei/pet-mirror/commit/2863bd4b6967d0174bd7834654aabe45361e8e39 .

Also I found polylib needs this patch to compile on my machine(it becomes werror on some machines):

```

```

It was created on 2016 while the polylib bundled with barvinok is from 2010.

For future reference, you should post the commit(s) here
(e.g., using git send-email), not a link to them.

Updated.

  Hello.

    Skimo, when will you post your fix? (Will you post it at git://repo.or.cz/ppcg.git ?)

  Thank you,

It should be there already. Is it not working for you?

  Hello.

    Skimo, unfortunately, it's not working for me. I got away from the previous errors, but now I get linker errors:

Are you using libclang from a distribution (which one?) or
did you compile it yourself?
Usually, it is configured to produce a libclang-cpp.
Do you have that?
If so, have a look in interface/config.log to see why it wasn't found.

  Hello.

    Sorry for the late reply.

    Skimo, I'm using libclang from Ubuntu 24.04 LTS - I used sudo apt get install libclang-18-dev.

    I looked in ppcg/isl/interface/config.log and found this error message:

        configure:20727: checking for main in -lclang-cpp

        configure:20749: g++ -std=c++11 -o conftest -g -O2 -I/usr/lib/llvm-18/include -std=c++17   -fno-exceptions -funwind-tables -D_GNU_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -I.  -L/usr/lib/llvm-18/lib   conftest.cpp -lclang-cpp   >&5

        /usr/bin/ld: cannot find -lclang-cpp: No such file or directory

    But there is a file /usr/lib/llvm-18/lib/libclang-cpp.so (and libclang-cpp.so.18.1) - I installed libclang-cpp through sudo apt get install clang. So the above g++ command shouldn't have given an error in my opinion.

    Please help.

  Thank you very much,

    Alex

Hmm... can you try installing libclang-cpp18-dev as well?

What does

ls -l /usr/lib/llvm-18/lib/libclang-cpp.so

say?

Can you reproduce it from the command line?

In the mean time, I've been trying to get it to work without libclang-cpp
as well, so you could also try the attached patch.

  Hello.

    Skimo, you can find my answers inlined in your reply.

I installed libclang-cpp18-dev. And after that I did a fresh install of PPCG (and its submodules) - and now it worked.

    ls -l /usr/lib/llvm-18/lib/libclang-cpp.so says:

     ... libclang-cpp.so -> libclang-cpp.so.18.1

    In fact, libclang-cpp.so is a sym-link to libclang-cpp.so.18.1 - I created manually the sym-link.

    No, because I'm not able to recreate the source file conftest.cpp.

In the mean time, I've been trying to get it to work without libclang-cpp
as well, so you could also try the attached patch.

    I don't have the file m4/ax_detect_clang.m4. How can I generate this file? So I can't apply the attached patch.

  Thank you,

OK, then I guess your problem is solved and
the other question are not really relevant anymore.

touch conftest.cpp

would've been enough.

It was a patch for isl. Perhaps you didn't cd into isl.
