Compilation error

[damdaepark]

Hi, I am trying to compile SHOT in Windows10 (64bit) by following the instructions on https://shotsolver.dev/shot/about-shot/compiling. But things are not going well, so ask if anyone can let me know a solution for this.

(base) PS C:\Users\Damdae\OneDrive - SNU\Installation Files\solvers\shot\SHOT\build> cmake .. -DCMAKE-BUILD_TYPE=Release -DHAS_IPOPT=on -DHAS_CPLEX_=on -DHAS_GUROBI=on

It's weird because Gurobi is detected while IPOPT is not. They are all in the PATH environment variable and reachable, as you can see below.

Hi,

There seems to be something wrong with your specified path to the Ipopt libraries (note, it should not point to the executable!):

Ipopt include files will be used from: C:\Users\Damdae\OneDrive - SNU\Installation Files\solvers\ipopt\bin\ipopt.exe/include/coin

The correct path should perhaps be:

C:\Users\Damdae\OneDrive - SNU\Installation Files\solvers\ipopt\lib?

[damdaepark]

I guess it is not a problem with PATH. Seeing that the lines starting from 244 in CMakeLists.txt, which are about Ipopt solver, are different from Gurobi and CPLEX cases, I guess the current implementation needs an IPOPT that has been compiled from the source files.

Can someone revise CMakeLists.txt so that it can run with IPOPT executable binaries in https://github.com/coin-or/Ipopt/releases?

[svigerske]

The binaries attached to the Ipopt releases do not include the pkg-config files that SHOT is looking for. (I excluded them, because I didn't think someone would have use for them.) Can you try creating a ipopt.pc in directory lib/pkgconfig of your Ipopt download with the content

prefix=${pcfiledir}/../..
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include/coin-or

Name: Ipopt
Description: Interior Point Optimizer
URL: https://github.com/coin-or/Ipopt
Version: 3.14.5
Cflags: -I${includedir}
Libs: -L${libdir} -lipopt
#Requires.private: coinmumps

Further, you need to install pkg-config (pacman -S pkg-config under MSYS2; or see https://stackoverflow.com/questions/1710922/how-to-install-pkg-config-in-windows).

If that works, I can include the .pc files in future Ipopt binary downloads.

I will close this now. Please feel free to reopen if you still have issues.
