Strange errors after system gcc upgraded to 13.1.1

Sanhu_Li · May 5, 2023, 9:40pm

Dear all!

I’m having an OpenACC project that compiles fine in the past. However, after a system upgrade (Arch Linux, gcc upgraded to 13.1.1), my project was broken.

The project compiles fine with GCC on CPU only.

The error persists no matter what c++ standard I use (tried default, c++11 c++14 and c++17).

Could someone please take a look and tell me is there anything wrong with my project or I should just downgrade my compiler?

Really appreciate your help!

The error messages I received:

Hi Sanhu_Li,

Not too surprising that there are issues given GNU 13.1 just came out and we haven’t been able to adjust to their changes. In order to be object compatible with g++, we need to use the GNU STL.

As for the error, I can recreate it with just including “iostream”:

% cat test.cpp
#include <iostream>
% nvc++ -c --gcc-toolchain=/home/sw/thirdparty/gcc/gcc-13.1.0/Linux_x86_64/ test.cpp "/home/sw/thirdparty/gcc/gcc-13.1.0/Linux_x86_64/lib/gcc/x86_64-pc-linux-gnu/13.1.0/../../../../include/c++/13.1.0/type_traits", line 3363: error: type name is not allowed

% nvc++ -c --gcc-toolchain=/home/sw/thirdparty/gcc/gcc-13.1.0/Linux_x86_64/ test.cpp --std=c++14
%

However for me, it appears to be limited to C++17. Setting “–std=c++14” works around the issue.

How are you setting the language version?

Can you please provide an example where it still fails with C++14?

Thanks,
Mat

Hi Mat!

Thank you so much for your help!
cmdb2-main.zip (764.1 KB)

Our project is currently private, but I can send you an archive to test it out (since it’s far from done).

The project is having some Rust code and some C/C++ code. In order to test, you just need to create a build folder at the root and cmake ../ and finally make.

In CMakeLists.txt, there’s a commented out line that can set up the CXX versions.

I think my code fails because it contains #include <algorithm>, but I’m not sure about this.

I don’t have the Arch Linux system at my hand right now, and I couldn’t test it out. I’ll tell you more when I find a system with gcc-13.

Thank you so much for your quick reply!

MatColgrove · May 6, 2023, 8:10pm

FYI, here’s some info I got back from engineering:

__is_convertible is a built-in operator than is new in GCC 13. Because it is brand new, our front-end doesn’t support it yet.

There is also a bug in the <type_traits> header in GCC 13.1. There are two uses of __is_convertible in that header. One of them is protected by #if __has_builtin(__is_convertible), and has a fallback mechanism when __is_convertible is not available. The other use doesn’t have that check. That’s the one that triggers the failure in nvc++.

GCC 13.1 is pretty much unusable with NVC++ 23.3 and earlier, because lots of headers include <type_traits>. I think there is a simple workaround that we can make so that GCC 13.1 <type_traits> will work with future releases.

Sanhu_Li · May 6, 2023, 11:35pm

Thank you so much for the updates! I’m on Arch Linux and currently everything is unusable. I tried to installed gcc-12 via homebrew but it’s giving me the following errors:

It seems cmake is looking at the wrong locations for crtbegin.o, after finding the file and setting the parent folder into $LIBRARY_PATH, I’m still having the same error messages.

Really appreciate your work and confirmation on this problem and I think I’ll re-install my OS with something not using gcc-13 right now for our code.

MatColgrove · May 8, 2023, 3:57pm

How did you configure NVHPC to use you homebrew GNU 12?

Did you edit the localrc file or use makelocalrc?

The location of the crt files is defined in the DEFSTDOBJDIR variable, which should point to a system directory not your homebrew. For example:

set DEFSTDOBJDIR=/usr/lib/x86_64-linux-gnu;

Not instead of editing the localrc file, you can use the “–gcc-toolchain=/path/to/base/gnu/install” instead.

Sanhu_Li · May 8, 2023, 10:07pm

Thank you so much for your help, Mat!

For now, I have already re-installed the OS and I’m now on Fedora 38 (which also uses gcc-13.1, and I also installed a gcc-12 through homebrew). This time it’s working smoothly.

I have called makelocalrc previously on Arch. However, it’s still not able to find the crt files. I think the reason is Arch is storing those files in a special path which include compiler version ( somewhere in the path there’s a 13.1 ), and that’s something making some of my compiles fail. I wasn’t aware about the DEFSTDOBJDIR thing, but I think if I knew it, it should work. Thank you so much for your help! I’m really happy I’m learning new things.

EDIT: I saw the problem again, I fixed it by setting the line GCCDIR line to the system one in the localrc file. Sadly the DEFSTDOBJDIR doesn’t seem to work this time.

Thank you so much for all your efforts helping me! I really appreciate it!

Hi Mat! Just recently had the same issue. Any chance 23.5 will have a workaround for this? In any case, I solved it by loading a GCC/12.3.0 module then using the “–gcc-toolchain” flag pointing to the install path of said module. Leaving my reply here so others can try the same workaround.

MatColgrove · May 22, 2023, 4:30pm

Engineering is testing a work around for the type_traits issue which hopefully can be added to 23.5. No guarantees that other issue wont occur, but it should work around this one (assuming it makes it in the final release).

MatColgrove · May 25, 2023, 9:15pm

Hi Lucas, Sanhu_li,

The work around for the __is_convertible issue in GNU 13’s type_traits header was added to 23.5. You might encounter other issues as we’re still working on compatibility issues with this new GNU release, but hopefully this will get you further.
