Cleaning up stuff

Hi guys This is a question related to the compilation system of osmocom-bb. For an unknown reason, something has gone wrong with my compiled binaries, so now I would like to clean up everything as it was freshly checked out, before restarting the compilation. How can I do it? Make clean and make distclean seem not to be enough, since my compilation now fails with: cd ./doc && tar cf html.tar */html make[3]: Leaving directory `/home/dario/Projects/mobile/osmocom-bb/src/shared/libosmocore/build-target' make[2]: Leaving directory `/home/dario/Projects/mobile/osmocom-bb/src/shared/libosmocore/build-target' make[1]: Leaving directory `/home/dario/Projects/mobile/osmocom-bb/src/shared/libosmocore/build-target' cd host/layer23 && ./configure checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /bin/mkdir -p checking for gawk... no checking for mawk... mawk checking whether make sets $(MAKE)... yes checking whether make supports nested variables... yes checking whether make sets $(MAKE)...

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: *** [host/layer23/Makefile] Error 1 How can I clean up everything? Any help appreciated. Thanks Dario.
