That's weird. What does libnsl contain if not gethostbyname()? The config.log answers my question -- quite a bunch of stuff. What I meant to say: it is a pretty strange Name Server Lookup library which doesn't contain gethostbyname(), but then again, it's a strange world. What I'll do for 1.7.1 is, replace `gethostbyname' with `inet_ntoa', which should cover both Solaris and the system Andre is using. Jan, you must be confusing something here. gethostname() only gets the local host name, and is just a wrapper for the appropriate uname() or sysinfo() call. It has nothing to do with name server lookups, which is what libnsl is supposed to do. Probably, but are you sure that this is true on _all_ systems? I'm not. :-( Sorry for the confusing remark. Perhaps we really should try to write a libtool-based macro named WGET_CHECK_EXTERNAL_LIB. Perhaps it would be more portable then. In the meantime, this [adding -Wl, to linker flags] has been solved very elegantly by Maciej Rozycki.

Re: Wget 1.7-pre1 available for testing
Quoting Andre Majorel ([EMAIL PROTECTED]):
Tuesday is today. config.log for 1.6 and 1.7-pre1 attached. 1.7
is identical to 1.7-pre1.
It seems that -lsocket is not found as it requires -lnsl for
linking. -lnsl is not detected as it does not contain
`gethostbyname()' function.
Would the attacheed patch to configure.in solve the problem? Please
not that the patch tries to correct somee other problems with
configure.in and these corrections may make it crash on your
system. The important change for you would be the
AC_CHECK_FUNCS(gethostname, [] ...) part.

Andre Majorel [EMAIL PROTECTED] writes: Tried it on NCR MP-RAS 3.0 : Thanks for testing it. - The CC -cX problem in wget 1.6 is fixed. Good. :-) You mean -Xc? I decided that strict ANSI mode is the wrong thing to look for. Among other things, it turns off useful extensions such as `long long'. It also often causes problems with the system header files which are not stress-tested for -Xc-compliance. - The empty LIBS problem remains (add -lsocket -lnsl). Do you have a config.log for this? Wget's configure tries hard to determine whether `-lsocket' and `-lnsl' are needed, and this seems to work on Solaris. Can you see why it fails on your machine? - utils.c doesn't compile because MAP_FAILED is not defined in the system headers, so : Ick. I guess we add this to `sysdep.h': #ifndef MAP_FAILED # define MAP_FAILED ((void *) -1) #endif Then the application code could use MAP_FAILED normally, without getting cluttered with ifdefs.
