Hi, I recently installed GCC 2.95.2 on SCO OpenServer 5.0.5. # gcc -v Reading specs from /usr/local/lib/gcc-lib/i386-pc-sco3.2v5.0.5/2.95.2/specs gcc version 2.95.2 19991024 (release) I can compile and run a c program but not an esql c. Getting following error when I try to compile ESQL C programs. crtbegin.o: fatal error: cannot open file for reading gcc: file path prefix `/usr/local/lib/gcc-lib/elf/2.95.2/' never used I set the environmental variable GCC_EXEC_PREFIX to /usr/local/lib/gcc-lib/ Can someone explain what this means and how to fix this? Thanks Hari.
