In the case of libsocket, it is not a cross-compiler problem; you always have to add -lsocket to the link libs when using things like socket(), or linking libraries that do (such as X11 libs). The problem is that when building a native gdb on solaris (with --target=i386-pc- solaris2.10), configure detects that -lsocket is required and adds it to the appopriate Makefile macros, but does not when building for x86 Solaris.... > > No, that's for target libraries. Gdb is a host program. The fact taht > build != host is irrelevant here; your "target" is i386-pc-solaris2.10, > and so is your "host".

Part of the confusion is that the sub-level configures don't get called until you run a top-level make, and not all environment variables set (such as LDFLAGS) at configure time get cascaded to the sub-level configure, and furthermore I'm not sure the sub-level Makefile is handling merging LDFLAGS from the environment and from the makefile (since I just want to tell it to add "-lsocket", not manually figure out every single library that needs to be linked). Any further help is much appreciated. -- Aaron Gaudio agaudio @ eng.mc.xerox.com 585-422-6876 While life is yours, live joyously; None can escape Death's searching eye: When once this frame of ours they burn, How shall it e'er again return?
