I am working on wine for Solaris, and the configure.ac segment at the bottom of the
post that searches for functions looks like this (I combined the single line functions
in AC_CHECK_FUNCS to mulitple entries per line to be more readable).
I've found that the following functions are not found:
connect, getaddrinfo, gethostbyname, getnameinfo, getnetbyname, getprotobyname,
getprotobynumber, get servbyport, inet_aton, inet_network, sendmsg.
The three specific checks for "Solaris" find the libraries, but don't set the
appropriate HAVE_<function-name> variables in config.h.
After lots of trial and error, comments, and research, I came up with adding
the following before the AC_CHECK_FUNCS test.
AC_CHECK_LIB(resolv,inet_aton)
AC_CHECK_LIB(nsl,gethostent)
AC_SEARCH_LIBS(socket, socket, ,
[AC_CHECK_LIB(nsl, socket, LIBS="$LIBS -lsocket -lnsl", , -lsocket)])
and then modify the post Solaris checks like:
- AC_CHECK_LIB(nsl,gethostbyname)
+ AC_CHECK_LIB(nsl,gethostbyname,[AC_DEFINE(HAVE_GETHOSTBYNAME,1)])
+ AC_CHECK_LIB(socket,connect)
+ AC_CHECK_LIB(socket,connect,[AC_DEFINE(HAVE_CONNECT,1)])
According to the config.log, gethostbyname and connect in the both original and
my modified configure.ac fail to define those funtions. The original configure.ac
found -lnsl and -lsocket, but the functions were not enabled. So I modified the
post AC_CHECK_FUNCS solaris tests for gethostbyname and connect, and
this works.
The dilemma? One of the maintainer claims that the the AC_SEARCH_LIBS for
socket enables "-lsocket" for more than Solaris.
As I'm not an autoconf guru, someone suggested I post here for suggestions?
Thanks,
Ben
