[Ipopt] Building HSL shared libraries

[Stefan Vigerske]

Hi,

it seems as if --enable-loadable-library has only an effect on windows.

To build a hsl library with ma27, you need the file ma27ad.f. Then 
ThirdParty/HSL should build a libcoinhsl.so. It should work if you just 
rename it to libhsl.so.

Another way is to build it directly via
  gfortran -shared -Wl,-soname,libhsl.so -fPIC -o libhsl.so <hsl-sources>
Sometimes, one has to exclude za02as.f or to add -lblas.

Well, in the MA27 source directory, though it has a configure --enable-loadable-library is not a recognized option.  The ThirdParty directory will recognize this option as well as --enable-shared, but it appears that nothing is being happening (this occured after placing ma27d.f and ma27s.f in the ThirdParty directory):
