Hello, I am suing Manjaro Linux (Arch Linux based) and do not get the osmocom-bb compiled.   git clone https://github.com/osmocom/osmocom-bb cd osmocom-bb/src make .... .... checking pkg-config is at least version 0.9.0... yes checking for LIBOSMOCORE... no configure: error: Package requirements (libosmocore) were not met: No package 'libosmocore' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables LIBOSMOCORE_CFLAGS and LIBOSMOCORE_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. make: *** [Makefile:69: host/layer23/Makefile] Fehler 1     but libosmocore is compiled and installed ( /usr/local )   $ ls -la /usr/local/include/osmocom/ insgesamt 40 drwxr-xr-x 10 root root 4096 12.
