Ipopt with OneAPI, HSL problem

[Leersmaekers]

I'm having some troubles installing Ipopt with with HSL and OneAPI (MKL). If I configure&install Ipopt without HSL, it all seems to work as expected. The OneAPI MKL Lapack libraries are found. However, if I first try to configure HSL with MKL Lapack, I reveive an error stating it cannot be linked with the user-specified Lapack. The line I used to link Lapack is the following:

--with-lapack-lflags="-L${MKLROOT}/lib/intel64 -Wl,--no-as-needed -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lm"

Does anyone have some suggestion to fix this issue?
(I did search online for a couple of hours, but nothing seems to fix my issue)

config.log

It's a bit odd that if it worked for Ipopt, it didn't for HSL. Can you attach also the config.log from the build of Ipopt without HSL?

It would be interesting to see how the Lapack test in Ipopt is different from the one in HSL (the one failing in config.log:725).

MKLROOT is set to C:\PROGRA~2\Intel\oneAPI\mkl\2023.0.0, which is a Windows-style path, whereas you are using Posix paths for everything else. I don't really see how this can work. Maybe try setting MKLROOT to a Posix path (or else just specify the path explicitly).

This is the log file that succeeded:

config.log

Looks like you use GCC when building HSL, but MSVC when building Ipopt.

For HSL, this one fails:

configure:21359: gcc -o conftest.exe -O2 -DNDEBUG    conftest.c -LC:\PROGRA~2\Intel\oneAPI\mkl\2023.0.0/lib/intel64 -Wl,--no-as-needed -lmkl_lapack95_lp64 -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lm  >&5

For Ipopt, this one succeeds:

configure:22983: checking for LAPACK
configure:23343: /home/LaurentK/Ipopt/compile cl -o conftest.exe -nologo -DNDEBUG -O2 -MD    conftest.c /c/PROGRA~2/Intel/oneAPI/mkl/20230~1.0/lib/intel64/mkl_intel_lp64_dll.lib /c/PROGRA~2/Intel/oneAPI/mkl/20230~1.0/lib/intel64/mkl_sequential_dll.lib /c/PROGRA~2/Intel/oneAPI/mkl/20230~1.0/lib/intel64/mkl_core_dll.lib  >&5

Try adding --enable-msvc also for the HSL build.

My file structure now looks as follows:
home/LaurentK
|- Ipopt
|- ThirdParty-HSL (I used this folder for configure/make/install)
|- ThirdParty
-----> ASL
-----> HSL (I didn't use this folder for configure/make/install)
-----> Mumps

Hmm, strange. I don't really know what is going wrong. (And I actually fear that configure would still fail if the -L flag were not lost.)

Maybe just try running Ipopt's configure with

--with-hsl-lflags=/usr/lib/coinhsl.dll.lib --with-hsl-cflags=-I/usr/include/coin-or/hsl

[Leersmaekers]

The line you suggested works perfectly fine. It's indeed strange that the other method didn't work.

After performing make install, are there include and lib folders created that can be used in Visual Studio? I now use the folders as provided with the Windows binaries.

[svigerske]

Yes, as far as I see, you get header files in /usr/include/coin-or, .lib's in /usr/lib, and DLLs in /usr/bin.

[Leersmaekers]

They are indeed installed in there. I was searching for an include folder, but it's indeed one level lower in coin-or. Thanks a lot for the quick answers!
