Libtool issue while compiling Liblinphone

Question

I'm trying to compile this lib:
https://github.com/BelledonneCommunications/linphone-iphone

During generation I get this:

/linphone-iphone/submodules/build/..//externals/speex/libspeex/cb_search.c
libtool: Version mismatch error.  This is libtool 2.4.6, but the
libtool: definition of this LT_INIT comes from libtool 2.4.2.
libtool: You should recreate aclocal.m4 with macros from libtool 2.4.6
libtool: and run autoconf again.
make[4]: *** [cb_search.lo] Error 63
make[3]: *** [all-recursive] Error 1
make[2]: *** [all] Error 2
make[1]: *** [build-speex] Error 2
make: *** [broadcast_all] Error 2

Ok, then, (as stated here) :

cd ../externals/speex/  
autoreconf --force --install

cd cd ../../build && make all

And... It happens again!
What's wring with libtool?

Answer 1

After you run autoreconf, the appropriate configure script has to be executed. Until then, it the work autoreconf does is not effective.

Sometimes make recognizes this, but it may not be the case here. Therefore I recommend you to run the top-level configure script (I assume that this is what you have ran at the beginning) and then resume building using make all.

You have probably hit a bug of how the software is distributed. If distributors think that they have to distribute the dependency as a sub-project of the software, they should take care that there are no discrepancies between libtool versions used.
