What kernel and glibc versions >does SuSE 6.1 use? I've verified that there is no problem on RedHat 6.0 provided you build the custom runner correctly. To verify this, I copied the file stamp.c from $INFORMIXDIR/demo/sql/en_us/0333 to a spare directory, and did: c4gl -c stamp.c cperf -o myperf stamp.o This compiled without errors (though the c4gl compilation gave me the obnoxious warnings from GCC about the libraries not being used -- that's a subject I've discussed previously, and provided a patch for; I need to install the patch on my installation some time). -- Yours, Jonathan Leffler (jonathan.leffler@informix.com) #include <disclaimer.h> Guardian of DBD::Informix v0.62 -- http://www.perl.com/CPAN "I don't suffer from insanity; I enjoy every minute of it!"
