Hi, Trying to emerge zygrib on a rather clean computer (new disk), I got the following error: .../bin/ld: cannot find -ljasper Emerging "media-libs/jasper" (1.900.6, current stable) before emerging "zygrib-8.0.1" fixes this issue. Thanks for your appreciated work ! Best regards, po valles
Thanks for your report. jpeg2000-Support is disabled in this version. Do you have a build log? I want to understand, why it failed for you. How does the "DEFS=" Variable look like after it failed in your build directory in "src/g2clib/makefile"? TIA

Ok, thank you. So its a bug in the build system of zygrib. I will first fix this so that jasper is not required anymore and maybe introduce a jpeg2k USE flag to enable jpeg2000 support.
Thanks again for the report! Should be fixed.
