metview doesn't seem to use a hard-coded version of gfortran but picks up on the error somewhere in the bowels of its CMake code.
When built, the tools GeoTool binary uses the usual /usr/lib/$ARCH/libgfortran.so.3 link. During building, it seems to pick up the /usr/lib/gcc/* version as seen in the report. It does this too on other archs, but there the '5' version is correct and all builds fine. metview had a dependency on gfortran but not libgfortran. So, it appears the bug is in gfortran somewhere but I'm not sure yet what metview / cmake did to tickle it. I have it in a schroot on fischer and can investigate further. regards Alastair -- Alastair McKinstry, <alastair.mckins...@ichec.ie>, t: +353 91 495343 Environmental Sciences Activity Leader, ICHEC, IT 301, NUI Galway, Ireland
