More with the antiquated Solaris compiler... I'm trying to build GAIA on Solaris 8 to no avail. I've set the following environment variables: F77 = f77 FC = f77 CC = cc CXX = CC ...in addition to the standard ones needed for the build. With a fresh checkout of the GAIA tree, in the 'make' phase I eventually get: make[3]: Entering directory `/export/scratch/starlink-cvs/applications/gaia/skycat/tclutil/util' for i in src include test man; do (cd $i; echo "$i:"; make all) || exit 1; done src: make[4]: Entering directory `/export/scratch/starlink-cvs/applications/gaia/skycat/tclutil/util/src' test -d ../lib || mkdir ../lib CC /opt/SUNWspro/WS6/include/CC/Cstd/./ios.cc -o /opt/SUNWspro/WS6/include/CC/Cstd/./ios ld: fatal: file /opt/SUNWspro/WS6/include/CC/Cstd/./ios: open failed: Permission denied make[4]: *** [/opt/SUNWspro/WS6/include/CC/Cstd/./ios] Error 1 make[4]: Leaving directory `/export/scratch/starlink-cvs/applications/gaia/skycat/tclutil/util/src' make[3]: *** [all] Error 1 make[3]: Leaving directory `/export/scratch/starlink-cvs/applications/gaia/skycat/tclutil/util' make[2]: *** [sub] Error 1 make[2]: Leaving directory `/export/scratch/starlink-cvs/applications/gaia/skycat/tclutil' make[1]: *** [all] Error 1 make[1]: Leaving directory `/export/scratch/starlink-cvs/applications/gaia/skycat' make: *** [rtdConfig.h] Error 1 Two questions: 1) Why is it trying to build in a system directory? 2) How can I stop it from doing so? I haven't done anything out of the ordinary with this build. Cheers, Brad.
