Hey. I couldn't stop myself: since Dave said that HPUX doesn't support symbol versioning, (no way, no how) I have changed libstdc++ configure to reflect this. :) Ranier, great to see you got something working. I've changed the summary again to reflect what is now left of this bug. You are correct in that --disable-shared turns off shared library versioning, since versioning only applies to the shared lib. I believe that this is a documentation-only bug at this point. In particular, I think that this documentation page: http://gcc.gnu.org/install/specific.html#hppa-hp-hpux Should reflect this discussion. As it stands this: There are a number of issues to consider in selecting which linker to use with the 64-bit port. The GNU 64-bit linker can only create dynamic binaries. The -static option causes linking with archive libraries but doesn't produce a truly static binary. Dynamic binaries still require final binding by the dynamic loader to resolve a set of dynamic-loader-defined symbols. The default behavior of the HP linker is the same as the GNU linker. However, it can generate true 64-bit static binaries using the +compat option. oddly changes: The GNU 64-bit linker has some issues with shared library support and exceptions. As a result, we only support libgcc in archive format. For similar reasons, dwarf2 unwind and exception support are disabled. The GNU linker also has problems creating binaries with -static. It doesn't provide stubs for internal calls to global functions in shared libraries, so these calls can't be overloaded. I can see how people are confused by this. GNU ld appears to not really work with shared or static libs, from the docs. (But maybe just for 64 bit targets?) But experience says it works with static libs, but not shared libs. Something needs to be changed, and this section should be updated with the latest status and best practice (which appears to be GNU as, HPUX ld). (FWIW, it looks like shared libgcc is being created on this target now with GNU ld or else this alone would turn off symbol versioning.) Some love here by people in the know would be helpful to all. I leave the edits to the target maintainer. -- bkoz at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Keywords| |documentation Summary|link/execute fails for cross|shared link/execute fails |gcc from linux to target |for cross gcc from linux to |hppa64-hp-hpux11.00 |target hppa64-hp-hpux11.00 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38384
