Internal compiler error on Arch Linux's gcc-7.3.1 #195

vutiqibyl · 2018-05-04T19:45:06Z

Trying to compile eos with the following commands (from the eos folder root) :

mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=../install/ -DEOS_GENERATE_PYTHON_BINDINGS=on
make & make install

Fails with an internal compiler error: unexpected expression
pip install eos-py leads to the same error.

What could cause this issue ?

Here is the full output of
cmake :

I've encountered this a few days ago too - unfortunately Arch Linux/gcc-7.3.1 seem to have a bug/regression that causes this. I would advise to report this bug to Arch/gcc so that it gets fixed.
In the meantime the only thing I can suggest is using a slightly earlier version of gcc (or maybe clang?).

patrikhuber · 2018-05-05T07:19:50Z

@vutiqibyl: The author of toml11 just had a stab at working around the ICE - I can't currently test it locally, but if you pull in the latest upstream master changes for the 3rdparty/toml11 submodule, it should presumably work again!
If you could try it and report back whether it works?

vutiqibyl · 2018-05-05T10:24:29Z

Thank you for your quick answer.
After doing a git checkout master and git pull from 3rdparty/toml11, the error no longer occurs, although I now get undefined reference to "Imf_2_2:: errors.
The same happens with clang-5.0.1.

Hey that's awesome, great!

The error you're getting now seems only related to OpenCV and has nothing to do with eos.
I have no idea what Imf_* is, but maybe installing libImath, libIlmImf, etc. and the rest of the stuff that it's complaining about helps? OpenCV shouldn't need these though so I strongly suspect this is specific to your system or to Arch/Manjaro. This would probably be something for the Arch/Manjaro forums.

Btw: eos doesn't need OpenCV - you only need OpenCV for the example programs, if you want to run them. The eos library doesn't need it.

This fixes #195 (ToruNiina/toml11#9).

Thank you, I switched EOS_BUILD_EXAMPLES to OFF with ccmake, and it now compiles without problem.
The undefined reference errors were due to a mismatch between the .so files (looking for .so.12 while they end with .so.23), and making soft links to the correct files solves the issue and allows the compilation with EOS_BUILD_EXAMPLES=ON as well.
