Configure Ipopt with Pardiso #341

Closed shixuan-zhang closed 5 years ago

shixuan-zhang commented 5 years ago

Hi, I am trying to install Ipopt with Pardiso 6.0 (not the MKL version) as the linear solver. When following the instructions https://www.coin-or.org/Ipopt/documentation/node19.html and issuing the command ../configure --with-pardiso="-qsmp=omp $HOME/Pardiso/pardiso600-GNU720-X86-64.so" I saw the following configuration error: checking whether user-supplied Pardiso library "-qsmp=omp /home/zhangshixuanus/Pardiso/pardiso600-GNU720-X86-64.so" works... configure: error: Pardiso library -qsmp=omp /home/zhangshixuanus/Pardiso/pardiso600-GNU720-X86-64.so does not seem to work The log file is attached below for reference. Any help would be greatly appreciated. config.log

In config.log, you will find some clues by searching for "does not seem to work". To test the library, a simple Fortran program was compiled with the command line:

gfortran -o conftest -O3 -pipe    conftest.f -qsmp=omp /home/zhangshixuanus/Pardiso/pardiso600-GNU720-X86-64.so

This resulted in errors:

gfortran: error: /home/zhangshixuanus/Pardiso/pardiso600-GNU720-X86-64.so: No such file or directory
gfortran: error: /home/zhangshixuanus/CoinOR/Ipopt-3.12.13/build/ThirdParty/Lapack/libcoinlapack.la: No such file or directory
gfortran: error: /home/zhangshixuanus/CoinOR/Ipopt-3.12.13/build/ThirdParty/Blas/libcoinblas.la: No such file or directory
gfortran: error: /home/zhangshixuanus/CoinOR/Ipopt-3.12.13/build/ThirdParty/Blas/libcoinblas.la: No such file or directory
gfortran: error: unrecognized command line option '-qsmp=omp'

So it seems the library does not exist in the location you specified and qsmp=omp is not a valid option.

Thank you very much for the reply. I apologize for the wrong name for the .so library file. Now I correct it and remove the unrecognized command line option '-qsmp=omp'. Still the middle three errors remain. I think it weird since I already ran the get scripts in the ThirdParty folders, following the installation instructions. So these two libraries should be found, right? config.log

svigerske commented 5 years ago

Yes and no. configure passes the .la files to gfortran, which gfortran does not know how to deal with. Maybe that's a bug or something.

Can you just let your Linux distribution install Blas and Lapack in your system and skip (remove) ThirdParty/{Blas,Lapack}? Then configure should pick these up instead.

shixuan-zhang commented 5 years ago

Thanks for the comment. There are Blas and Lapack installed in the system and thus I tried removing the folders ThirdParty/{Blas, Lapack}. Turns out that the error persists. I notice that the configure script is trying to find -lcoinblas -lcoinlapack instead of -lblas -llapck. Does this cause the problem? config.log

svigerske commented 5 years ago

It should only do this if it still tries to use the version from COIN-OR. But it seems that it does not find blas installed in your system:

configure:25359: checking whether -lblas has BLAS
configure:25475: gcc -o conftest -O3 -pipe -DNDEBUG -Wimplicit -Wparentheses -Wsequence-point -Wreturn-type -Wcast-qual -Wall -Wno-unknown-pragmas -Wno-long-long   -DIPOPT_BUILD   conftest.c -lblas  >&5
/opt/rh/devtoolset-7/root/usr/libexec/gcc/x86_64-redhat-linux/7/ld: cannot find -lblas
shixuan-zhang commented 5 years ago

I see. Thank you very much. I made it work by adding the options --with-blas-lib="${BLAS}" and --with-lapack-lib="${LAPACK}", where the environment variables point to the path of the Blas and Lapack library files.
