Re: [Help-glpk] Jdk Version required for glpk-4.49

[Heinrich Schuchardt]

Dear Sankar,

thank you for your problem report. I will add
-source 1.6 -target 1.6
to Windows build files of the next release of GLPK for Java.

In the Linux make file this is already done.

Best regards

Heinrich Schuchardt
