fix tests linking: don't use system installed libs Do not link against the system-wide installed libosmo* libs when building the regression test programs. Always use the locally built ones. Linking some libosmo libraries causes libtool to pull in other libosmo libs even though they were not explicitly named. For example, ctrl_test explicitly links libosmoctrl, but this also has dependencies to libosmovty and libosmogsm: ldd src/ctrl/.libs/libosmoctrl.so | grep osmo libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007f26c26d4000) libosmogsm.so.10 => /usr/local/lib/libosmogsm.so.10 (0x00007f26c22bb000) libosmovty.so.4 => /usr/local/lib/libosmovty.so.4 (0x00007f26c2171000) If we omit explicit LDADD of these dependencies in the Makefile.am, libtool will take the first canonical place to find them, which may just be the already installed older versions of the same libs, which may or may not be compatible with the current build. In any case, it is never intended to link installed libs. All library dependencies are listed by this quick script: cd libosmocore for l in $(find . -name "*.so") ; do echo; echo "$l"; ldd $l | grep libosmo; done ./.libs/libosmocore.so ./coding/.libs/libosmocoding.so libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007f25fc3c2000) libosmogsm.so.10 => /usr/local/lib/libosmogsm.so.10 (0x00007f25fbfa9000) libosmocodec.so.0 => /usr/local/lib/libosmocodec.so.0 (0x00007f25fbf9b000) ./codec/.libs/libosmocodec.so libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007fb4c900d000) ./ctrl/.libs/libosmoctrl.so libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007f5df5129000) libosmogsm.so.10 => /usr/local/lib/libosmogsm.so.10 (0x00007f5df4d10000) libosmovty.so.4 => /usr/local/lib/libosmovty.so.4 (0x00007f5df4bc6000) ./gb/.libs/libosmogb.so libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007f788e536000) libosmovty.so.4 => /usr/local/lib/libosmovty.so.4 (0x00007f788e3ec000) libosmogsm.so.10 => /usr/local/lib/libosmogsm.so.10 (0x00007f788dfd3000) ./vty/.libs/libosmovty.so libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007f3b7ed21000) ./gsm/.libs/libosmogsm.so libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007fc69472e000) ./sim/.libs/libosmosim.so libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007f2f6412d000) libosmogsm.so.10 => /usr/local/lib/libosmogsm.so.10 (0x00007f2f63d14000) Add all explicit linking of all required library dependencies in all regression test programs, as shown by above listing. Example for reproducing a problem: In libosmocore.a, introduce a new function, and call that from libosmovty code. For example, I made loglevel_strs non-static in logging.c, and used that in logging_vty.c. Build and install this in a place where libtool can find it. Then go back to before this change and rebuild. You will see that linking ctrl_test (before this patch) then complains about libosmovty requiring the loglevel_strs symbol which it cannot find in libosmocore.so.

This repository contains a set of C-language libraries that form the core infrastructure of many Osmocom Open Source Mobile Communications projects.
Historically, a lot of this code was developed as part of the OpenBSC project, but which are of a more generic nature and thus useful to (at least) other programs that we develop in the sphere of Free Software / Open Source mobile communications.
There is no clear scope of it. We simply move all shared code between the various Osmocom projects in this library to avoid code duplication.
The libosmcoore.git repository build multiple libraries:
The official homepage of the project is https://osmocom.org/projects/libosmocore/wiki/Libosmocore
You can clone from the official libosmocore.git repository using
git clone git://git.osmocom.org/libosmocore.git
There is a cgit interface at http://git.osmocom.org/libosmocore/
Doxygen-generated API documentation is generated during the build process, but also available online for each of the sub-libraries at http://ftp.osmocom.org/api/latest/libosmocore/
Discussions related to libosmocore are happening on the openbsc@lists.osmocom.org mailing list, please see https://lists.osmocom.org/mailman/listinfo/openbsc for subscription options and the list archive.
