[Ipopt] 3.13.2 with binary coinhsl and Java interface reports libhsl.so: undefined symbol: dtrsm_

[Stefan Vigerske]

Hi,

probably the HSL library was not linked against Blas, so it is missing 
some symbols.
If you cannot fix the library, then you could try if it works better 
when changing dlopen(libName, RTLD_NOW) to dlopen(libName, RTLD_NOW | 
RTLD_GLOBAL) in Ipopt's src/contrib/LinearSolverLoader/LibraryHandler.c

But the --with-hsl that you specified is not working as you might have 
intended. It expects the linker flags to use for linking against an HSL 
library, so probably something like
   --with-hsl="-lcoinhsl -llapack -lblas"
In your build, Ipopt's configure concluded that it doesn't have HSL for 
the build and also no other linear solver, so it tries to load MA27 from 
a library libhsl.so at runtime.

I created a file named 'coin-hsl-usr-local-lib.conf' in /etc/ld.so.conf.d/.  The file contains the path /usr/local/lib.  I then ran ldconfig.  I can see that ldconfig knows about libcoinhsl:
