That's why I need to add the RTLD_GLOBAL flag after running
autogen.sh.
I'm using the following version of the autotools.
autoconf (GNU Autoconf) 2.61
automake (GNU automake) 1.10
libtoolize (GNU libtool) 1.5.22
Sorry, I made a mistake ... I works fine for me too with LT 1.5.22
It seems that the problem is with LT 1.5.24
With this version, I only have in my sys_dl_open():
lt_module module = dlopen (filename, LT_LAZY_OR_NOW);
If you're running LT 1.5, that makes sense -- the loaders/ directory
is new in the LT 2.x series, IIRC. However, 1.5.22 should *default*
to RTLD_GLOBAL; the switch to RTLD_LOCAL was a change in the LT 2.x
series.
Indeed, when I used 1.5.22, I see the following in my sys_dl_open():
lt_module module = dlopen (filename, LT_GLOBAL | LT_LAZY_OR_NOW);
And LT_GLOBAL is a #define for RTLD_GLOBAL.
Are you seeing something different?
What OS are you using?
Linux

We are testing for a specific line when looking for this patch:
test ! -z "`grep 'filename, LT_LAZY_OR_NOW' opal/libltdl/
loaders/dlopen.c`"; then
If this line is different in your dlopen.c, then it doesn't find it
and therefore autogen.sh doesn't patch it.
Did you already patch dlopen.c, perchance, or is your original
dlopen.c different than this?

It seems that I need this flag. However when I run autogen.sh, I get
the
following:

Hi,
I have the same error message when fault tolerance is activated.
I'm using gcc version 4.1.3, with Ubuntu 7.10 (i686) (kernel

If you want to use the pessimist message logging you have to use
the "-
mca vprotocol pessimist" flag on your command line. This should
work
despite the bug because if I understand correctly, the issue you
experience should occur only when fault tolerance is disabled.
I have troubles to reproduce the particular bug you are
experiencing.
What compiler and what architecture are you using ?
