As it stands today, I'm adding

I've just converted an application to use libtool and ltdl for opening

strips when lt_dlsym is called. That all worked fine.

This works, thanks. Although automake wants it the other way around

For the application I support, we use our own directory scanner to

would be useful if this capability was included as part of libltdl.
You can pass a directory path to lt_dlforeachfile, which will then

lt_dlforeach already calls a user function for each loaded module, perhaps all

On IRIX, libtool and MIPSPro CC don't get along. To compile
standard C++ code, you need the -LANG:std option, but libtool doesn't
even pass it down to the actual command line, so your code doesn't compile!
This problem and its workaround have, oddly enough, been documented,

Libtool (probably the 1.5 release) did used to work under MinGW. A
recent libtool from CVS does not work properly under MinGW. The
symptom is that libtool checks a DLL's validity using the 'file'
command. This fails so use of the DLL library is rejected.

Hi,
I wanted to use the build, host, target options to compile a natively
cross-compiled(namely from i686-pc-linux-gnu to i686-pc-linux-gnu)
GNU/linux distribution.
But right at the beginning with the binutils I got stuck because:
