AmplSolver fails to link due to missing libcoinasl symbols

[notwa]

this is occurring when attempting to build Ipopt 3.13.3 with MSYS2 (mingw64 target) and my build script which downloads and builds the coin-or dependency chain up to Bonmin.

make[2]: *** [Makefile:447: ipopt_sens.exe] Error 1

the symbol suf_rput_ASL is defined in libcoinasl.a, so I suppose the solution is to append its path to the command, or as a libtool dependency, but I can't figure out which variable to edit due to all the indirection induced by autoconf, automake, libtool and pkg-config.

[svigerske]

Yes. I guess it's not sufficient that libipoptamplinterface links against the ASL lib already.
Can you try whether the fix on branch 416-fix works?

[notwa]

yes, that works, thank you!
I suspect there will be similar linking errors for Bonmin. I'm already running into one, but not one that I expected. I'll have to make an issue on the Bonmin project if I can't get it to work.

@notwa Just wanted to quickly mention that coinbrew does what your build script is doing, but has a lot of additional bells and whistles. I haven't gotten to modifying the READMEs of the projects downstream of Cbc yet.

coinbrew fetch Bonmin@master
coinbrew build Bonmin -j 4
