ehlo,
I checked some manual pages, where [ug]?id types are used and each manual page suggest to include header file "sys/types.h". This header file was indirectly included in some files on linux, but it is not portable.
man getgid #include <unistd.h> #include <sys/types.h>
gid_t getgid(void); gid_t getegid(void); ------------------------- man getpwuid #include <sys/types.h> #include <pwd.h>
struct passwd *getpwuid(uid_t uid);
Attached patch modify header file "sss_idmap.h". Should be version-info changed for libsssidmap?
