Hi,
I'm using this great "libltdl" library for dynamic loading on lots
of Unix/Linux platforms. I build a "module" to be loaded at runtime.
All is well, except on AIX 5.2. What happens is that libtool part of
the build produces a binary with soname ".so", but this file is also,
according to AIX tradition, put into a AR archive. And this is what is
installed with "make install".
I have a small test program that uses "libltdl" and it complains the
format of this file is unknown. If I unpack the ".so", that binary
loads fine.
A few questions
- How do I prevent the AR version to be installed with "make install",
but instead get the ".so" version, i.e. a module I can load?
- I saw there are some versions, or hacked versions, of "ltdl.c"
floating round that sets RTLD_MEMBER on AIX, enabling opening
a "module" inside a AR container. As far as I can see, this never
made it to the official source, why not?
- Browsing the source of libtool (in no way claiming I understand
anything I see), I come across a symbol "aix_use_runtimelinking"
that seems to prefer ".so" over the AR container, but it is set if
"-brtl" is in LDFLAGS. I thought libtool was to protect me from
depending on flags, that I in my Makefile.am need to write
something like
# Set with AM_CONDITIONAL in configure.in
if WANT_AIX_RUNTIMELINKING
mymodule_la_LDFLAGS = -brtl
endif
Or do I misunderstand, that the way to control this is somethig
else?
Sorry if part of this is automake questions, it is so hard to tell
sometimes from the user perspective.
Thanks,
kent
