i have trouble starting my application since I get undefined references.
As source I determined the variable "link_all_deplibs_CXX" wich is
explicitly set to 'no' in libtool.m4.
I'm running libtool-1.5.6 under debian Sarge and the problem is, that the
libtool.m4-file is different from the one that comes with the
libtool-distribution from the homepage.

Yes.  Debian is AFAIK the only distribution that ever sets
link_all_deplibs to no on linux.

My question is, can I set the value of "link_all_deplibs_CXX" by hand, eg
as option in the commandline?

You can either change `libtool.m4' and/or whereever the package you are
talking about stores its m4 macros then rebuild the package or you can
change generated `libtool' -- look for all instances of


and set them to `unknown' or `no' (one at the beginning and several ones
at the end, one for each language -- search for

You could also tell us what specific problem you have encountered, so we
can warn against it or help you (the Debian maintainer usually reads
this list as well :)  or maybe just fix the package you are trying to


Hi Ralf,

well, I think the problem is on my side. The problem is the following:
I habe libraries libA and libB and my application app. app uses functions from libA and libB, and libA uses functions from libB. So I linked libA against libB and my app against libA. This worked fine, but now I get undefined references, unless I also link libB against app.

I dont't know, if this is intended, since I didn't care much about linking in the past. I also wonder about the output of ldd. I one line, it says "libB => not found" and serveral lines below, it finds libB in the correct directory. This is, well, a little confusing ;)
