Hello, I've been trying to build krb5 1.13.2 on my old G4 Power Mac (PPC) with OS X 10.4.11 I've got the following error in clients/ksu/main.c : main.c: In function "get_configured_defccname": main.c:818: error: void value not ignored as it ought to be *** [main.o] Error 1 indeed, unsetenv() returns void (OS X 10.4) : man 3 unsetenv ... void unsetenv(const char *name); ... HISTORY The functions setenv() and unsetenv() appeared in Version 7 AT&T UNIX. >From a recent linux man : Prior to glibc 2.2.2, unsetenv() was prototyped as returning void; more recent glibc versions follow the POSIX.1-2001-compliant prototype shown in the SYNOPSIS. regards, -- Thomas Bernard - thomas.bernard@cls.to Conseil Logiciel Securite SAS 1 Passage du Surmelin 75020 Paris
