Re: [Help-glpk] Configuration problem to use GLPK for Java on windows

[Heinrich Schuchardt]

Hello Adrien,

Does this work ( it should run some test cases):
open cmd.exe
cd F:\Solvers\glpk-4.52\w64
check_jni.bat

Is Eclipse calling a 64 bit Java runtime?

Which value do you get for
System.getProperty("os.arch")

Best regards
