Compile error with SPRAL GPU support

Hi everyone, I'm trying to compile IPOPT with SPRAL (compiled with GPU support).
As a first step I compiled hwloc with CUDA support. Then I compiled spral with these commands:

git clone https://github.com/ralna/spral
cd spral && ./autogen.sh
mkdir build && cd build
cp ../nvcc_arch_sm.c ./
CFLAGS=-fPIC CPPFLAGS=-fPIC CXXFLAGS=-fPIC FFLAGS=-fPIC FCFLAGS=-fPIC \
../configure --with-blas="-lopenblas" --with-lapack="-llapack" --with-metis="-L/usr/local/lib -lcoinmetis" --with-metis-inc-dir="-I/usr/local/include/coin-or/metis" --prefix=/home/erturk/spral
make && make test
make install

After SPRAL compilation I download and try to compile IPOPT with these commands:

git clone https://github.com/coin-or/Ipopt
cd Ipopt && mkdir build && cd build
../configure --with-spral-lflags="-L/home/erturk/spral/lib -lspral -lgfortran -lhwloc -lm -lcoinmetis -lopenblas -lstdc++ -fopenmp -lcudadevrt -lcudart -lcuda -lcublas" --with-spral-cflags="-I/home/erturk/spral/include"
make -j$(nproc --all) && make test
sudo make install

I get these errors:

/usr/bin/ld: /home/erturk/spral/lib/libspral.a(dense_factor.o): warning: relocation against `_ZN48_GLOBAL__N__16e07778_15_dense_factor_cu_8d0d865713cu_block_cholIdLj8ELj3EEEviiPKT_iPS1_iPi' in read-only section `.text'

/usr/bin/ld: final link failed: bad value

I attached config.log file.

Looks to me as if the -fPIC didn't get applied when dense_factor.o and assemble.o were built. You may want to inspect the log of make from the Spral build (though I used similar flags).

I attached SPRAL build config.log. I don't have extensive knowledge. I have Geforge 1650Ti mobile architecture Turing = sm_75. I installed cuda with "sudo apt install nvidia-cuda-toolkit".

commented

Maybe try NVCCFLAGS=-fPIC when configure Spral. Just a guess. I never tried Spral with GPU. Maybe the Spral project would be a better place for this.

Unfortunately did not work. I will try my luck in SPRAL repo. Thanks for fast response.
