HSL solvers on IPOPT [undefined symbol: dtrsm_]

[Yuki]

Hello all,

I've been using casadi and I really enjoy casadi! I'd like to ask one question about my problem with the HSL solver with ipopt.

I followed this to use different HSL solver. My  questions are

1. where should I run this command (./configure --prefix=(where_you_want_to_install) LIBS="-llapack" --with-blas="-L/usr/lib -lblas" CXXFLAGS="-g -O2 -fopenmp" FCFLAGS="-g -O2 -fopenmp" CFLAGS="-g -O2 -fopenmp")? I guess I should run in metis-4.0.3 directory but in the directory there is no configuration files so I just skipped this part. Maybe this skip results in my problem.
2. So, when I run casadi with ipopt, I got the following error:
   ---
   Exception of type: OPTION_INVALID in file "../../../../Ipopt/src/Algorithm/IpAlgBuilder.cpp" at line 393:
    Exception message: Selected linear solver HSL_MA86 not available.
   Tried to obtain HSL_MA86 from shared library "libhsl.so", but the following error occurred:
   /home/yuki/research/driver/coinhsl-linux-x86_64/lib/libhsl.so: undefined symbol: dtrsm_
   ---
   Could anybody help me with how to fix this issue?

For your reference, I'm using Ubuntu 20.04. Also, I got this result:

---

ldd ~/research/driver/coinhsl-linux-x86_64/lib/libhsl.so 

        linux-vdso.so.1 (0x00007ffece3d2000)

        libgfortran.so.3 => /lib/x86_64-linux-gnu/libgfortran.so.3 (0x00007fc910edf000)

        libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fc910d90000)

        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fc910b9e000)

        /lib64/ld-linux-x86-64.so.2 (0x00007fc911567000)

I also got this:

/coinhsl-linux-x86_64/lib$ nm libhsl.so | grep -i dtrmm

                 U dtrmm_

I look forward to hearing from you!

Best regards,

I think you  can install HSL separately from IPOPT

Meaning build IPOPT installation without hsl

Install HSL where cmake can find it (/usr/local ...)

Go to casadi/build folder

cmake -DWITH_HSL=ON -DWITH_IPOPT= ON ..

IPOPT has a linear solver loader so if you install HSL as a dynamic library, it should be able to use it without reinstalling IPOPT or CasADi. Otherwise, this is mainly a question for the IPOPT mailing list. 

"dtrmm_" is a LAPACK routine however, so maybe the installation fails because you don't have BLAS/LAPACK in your path.
