Hi all, I was compiling samba-2.2.2 on AIX415 but encounter some problem. Below is the problem during the compilation. Need to know if anyone has seen this problem? .................................... Compiling nsswitch/wb_common.c nsswitch/wb_common.c: In function `write_sock': nsswitch/wb_common.c:184: `fd_set' undeclared (first use in this function) nsswitch/wb_common.c:184: (Each undeclared identifier is reported only once nsswitch/wb_common.c:184: for each function it appears in.) nsswitch/wb_common.c:184: parse error before `r_fds' nsswitch/wb_common.c:190: `r_fds' undeclared (first use in this function) make: The error code from the last command is 1. Stop. Any respond is appreciated. thanks, -Bridget
