Hi, I'm trying to compile qmail-qfilter on a sparc box running Solaris ver 7 and for me its problems galore - please assist. Upon compiling with default Makefile, I get an error: In file included from qmail-qfilter.c:26: fork.h:4: conflicting types for `fork' /usr/include/unistd.h:274: previous declaration of `fork' fork.h:5: conflicting types for `vfork' /usr/include/unistd.h:472: previous declaration of `vfork' Since, Solaris supports vfork, I remark the fork include file and the fork error disappears.....I now remain with the errors: ./load qmail-qfilter setenv.o Undefined first referenced symbol in file unsetenv qmail-qfilter.o ld: fatal: Symbol referencing errors. No output written to qmail-qfilter collect2: ld returned 1 exit status *** Error code 1 I've tried with some Makefile variations but nothing works for me....any one able to shed some light on this? Thanks, Samuel.
