In the meantime I found a linker-option on AIX that
discards the path of a library in the loader section
of an *executable* that links against it: -bnoipath.
On execution, it means that the lib is loaded by means
of its hard-coded -blibpath and/or LIBPATH from the
environment. When the link-option is not specified it
defaults to -bipath, which means upon execution the
path in the lib's loader section is used.
On Linux, boost-build uses -soname that strips the
preceding path from the *library* itself and only
stores the soname in its loader section. Hence, only
the name will end up in the loader section of an
executable (like on AIX) and -rpath/-rpath-link and/or
LD_LIBRARY_PATH are used to find the lib during
Thus, -soname and -bnoipath are very similar, but an
-soname-equivalent might be desirable. I just started
porting an application to AIX for the first time so I
lack AIX-experience, but as far as I can see the
-bnoipath is as close as it gets.
Is there any AIX expert that can confirm this?
