This is very strange. Which compiler do you use for the compilation? Is it a new MAC OS X / processor?

FYI

Apple clang version 12.0.5 (clang-1205.0.22.11)
Target: x86_64-apple-darwin20.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

It is on a MBP'16 2019 Intel model.

Try to install manually and check whether this works.

I tried above and it fails in another place:

github/souffle-2.1/src/include/souffle/utility/ParallelUtil.h:43:10: fatal error: 'omp.h' file not found
#include <omp.h>

Oh - you haven't installed gcc. Could you install gcc and openMP?

I have gcc installed, but cmake will automatically select clang for default compiler. In the document, Clang is well supported and OpenMP is supported after Clang v3.7+. Maybe it is a problem of CMakeLists.txt which does not include -fopenmp flag properly?

Any updates on this issue? I am facing the same issue on the lastest macOS

[b-scholz]

Would you like to help?

[rahlk]

Absolutely, please let me know how I can help.

Ok, I was able to get this to work by looking at the old build instructions from v2.0.2. The issue is most likely with Apple's clang gcc/g++ and with brew's version.

Try this:

1. Reinstall gcc

brew reinstall gcc

2. Link bison/libffi

brew link bison --force
brew link libffi --force
export PKG_CONFIG_PATH=/usr/local/opt/libffi/lib/pkgconfig/

You may get an error here saying Warning: Refusing to link macOS provided/shadowed software: bison. In that case, just follow homebrew's recommendations.

3. Clone the souffle repo, and install.

git clone --branch 2.1 https://github.com/souffle-lang/souffle
cd souffle

If you have previously cloned the repo, cd into it and clean cmake cache with cmake --build ./build/ --target clean

4. Export the correct versions of CC/CXX and then use cmake.

export CC=gcc-11
export CXX=g++-11
cmake -S . -B build -DCMAKE_INSTALL_PREFIX=<path/to/install/dir>
cmake --build build --target install -j8

[b-scholz]

That is great! Basically, we need to rewire the cmake scripts to pick up gcc rather clang.

[b-scholz]

We could also set the flags as with

-DCMAKE_C_COMPILER='gcc-11' -DCMAKE_CXX_COMPILER='g++-11'

[b-scholz]

We would need to add these flags here:

homebrew-souffle/Formula/souffle.rb

Line 21 in ce73f57

system "cmake", "-B", "build", "-S", ".", "-DCMAKE_INSTALL_PREFIX=#{prefix}","-DSOUFFLE_GIT=OFF", "-DSOUFFLE_BASH_COMPLETION=OFF"

And add the gcc/g++ dependency. Would you like to create a pull-request for this?

[b-scholz]

The GCC dependencies needs to be added here:

homebrew-souffle/Formula/souffle.rb

Line 10 in ce73f57

depends_on "bison" => :build
