What version are you running and how was it built?

Threading requires par2cmdline to be compiled with OpenMP support.

Thank you for replying to my message.
I installed llvm via homebrew to get OpenMP support

Goku-104:par2cmdline-master jmurray$ par2 -V
par2cmdline version 0.8.1

I installed both from source code, and homebrew, but it looks like it's compelled with out OpenMP support, on both ways.

[animetosho]

Was par2cmdline compiled with OpenMP enabled?

[vmiyoshi]

This is how I installed llvm -

brew install llvm
LDFLAGS="-L/opt/homebrew/opt/llvm/lib -Wl,-rpath,/opt/homebrew/opt/llvm/lib"
export LDFLAGS="-L/opt/homebrew/opt/llvm/lib"
export CPPFLAGS="-I/opt/homebrew/opt/llvm/include"

and par2cmdline based on what I saw in the Readme -

./automake.sh
./configure
make
make check
sudo make install

Let me know if I did something wrong.

[vmiyoshi]

I think I got it
I had to use the -s, and --cc flags in homebrew

brew install par2 -s --cc llvm_clang

I see the flag now in par2cmdline
