I'm trying to compile cudaSolvers but I've got errors like the following. Does anyone successfully compiled these solvers on their computers ??

/usr/local/cuda-6.5/include/cusp/system/cuda/detail/multiply/coo_serial.cu: In function ‘void cusp::system::cuda::spmv_coo_serial_device(const Matrix&, const Array1&, Array2&)’:

My guess is that Dominik Christ did that, he works for http://wikki.co.uk

Hi,
I was struggling also with cudaSolver compilation. I found out that by reverting to cusp library v0.4.0 might do the trick.

git clone --branch v0.4.0 https://github.com/cusplibrary/cusplibrary.git cusplibray
cd cusplibrary
git checkout -b v0.4.0
copy cusp directory to your cuda install path

I had also to change cuda_lib_dir to lib64 in customized etc/prefs.sh
export cuda_lib_dir=$cuda_dir/lib64

go to $FOAM_SRC/cudaSolvers
./Allwmake



Regards,

OS system:
ubuntu 14.04
grapic video = Geforce 970, with cuda_6.5.19_linux64.run
openfoam: foam-extend-3.2 (nextRelease branch)
gcc (Ubuntu 4.8.4-2ubuntu1~14.04) 4.8.4

Hi,ThierryRochemont
have you solved this problem?
I followed your step by add the "export cuda_lib_dir=$cuda_dir/lib64" to the path foam/foam/foam-extend-3.1/etc
and I used the cusp v0.5.1, cuda7.0
but I still get the same problem.
I hope I can get your help which will save me from the debug nightmare.

You need to switch to cusp library v0.4.0

[zhihongliu]

Thank you, Svensen
I have compiled it correctly by using the cusp library v0.4.0
But I am still confused why cusp v0.5.0 show the error: expected primary-expression before ‘<’ token.

This is what got mine to compile.
