Re: [Help-glpk] Cross Platform IDE for mathprog development.

[Chris Wolf]

I forgot to upgrade to glpk-4.43, which solved the "symbol not found" error.
I also was able to successfully run "make check" for the JNI code with 
the 32 bit VM (java-1.5) on Mac, so the java wrapper is fine on MacOS.


Thanks,
