Support
1

I have succesfully complied ctranslate2 on R-Pi 64 bit.
Now, I am trying to complile it for 32bit R-pi.
I am getting error while cmake command…make[1]: *** [CMakeFiles/Makefile2:96: CMakeFiles/ctranslate2.dir/all] Error 2
make: *** [Makefile:130: all] Error 2

Steps I have followed -
git clone https://github.com/OpenNMT/CTranslate2.git

cd CTranslate2

git submodule update --init

cmake -DWITH_MKL=OFF -DWITH_CUDA=OFF -DWITH_OPENBLAS=ON -DWITH_DNNL=OFF -DWITH_ACCELERATE=OFF -DOPENMP_RUNTIME=NONE -DWITH_TESTS=ON -DCMAKE_PREFIX_PATH=/opt/OpenBLAS

make -j4 <— error came.
PLease help in this regard.
