 a *.pc file, I want to convert *.pc file to executable file.In directory $oracle_home/precomp/demo/proc this is a file demo_proc.mk is used to make file,when I used make -f demo_proc.mk filename command ,because the C compiler on my solaris is gcc in place of cc,so I modify env_precomp.mk file where CC=cc is changed to CC=gcc.But when I run make -f demo_proc.mk filename error occurd (build error or target filename.o error),I don't know how to do ,please help me.
