Re: [Help-glpk] Linking error in AIX 6.1 for glpk 4.47

[Reginald Beardsley]

The only things in all of glpk 4.47 that start with _glp are a set of #defines 
in glpk.h which rename a large number of functions in any file which includes 
glpk.h.  So removing these from glpk.h is unlikely to correct the problem 
unless the compiler is objecting to the leading underscore in an obtuse manner.

I think the threadsafe point may be nearer the mark.  My experience of the AIX 
compilers was that the depth of semantic analysis was much deeper than the Sun 
& HP compilers.  The link could be failing because the compiler detected that 
some code is not threadsafe, but the error message is unclear about the problem.

Without the symbol table information from nm(1) all of this is somewhat 
speculative.  The fact that the code compiles and presumably runs on Solaris, 
Linux and HP suggests that a compiler option is causing the problem.  I'd also 
suggest looking closely at the compile time messages from building GLPK for a 
"not threadsafe" message.  My leading supposition is still that the libglpk.a 
names have been mangle, but not the names in the caller.

Have Fun!
