compiling Opensips on Clion: missing tap.h, which library is missing? - cmake

Question

I am trying to compile Opensips on Clion as I want to debug and step through the code. I have tried adding environment variables through following lines in CMakeLists.txt:
set(CMAKE_C_FLAGS "-funroll-loops -Wcast-align -Wall -minline-all-stringops -falign-loops -ftree-vectorize -mtune=nocona -Wold-style-definition -Wmissing-field-initializers -Wredundant-decls" )
add_definitions(-DPKG_MALLOC -DSHM_MMAP -DUSE_MCAST -DDISABLE_NAGLE -DSTATISTICS -DHAVE_RESOLV_RES -DF_MALLOC -DF_MALLOC_OPTIMIZATIONS -DNAME='"opensips"' -DVERSION='"2.4.2"' -DARCH='"x86_64"' -DOS='"linux"' -DCOMPILER='"gcc 4.8.5"' -D__CPU_x86_64 -D__OS_linux -D__SMP_yes -DCFG_DIR='"/usr/local//etc/opensips/"' -DVERSIONTYPE='"git"' -DTHISREVISION='"c035556"' -DFAST_LOCK -DADAPTIVE_WAIT -DADAPTIVE_WAIT_LOOPS=1024 -DHAVE_GETHOSTBYNAME2 -DHAVE_UNION_SEMUN -DHAVE_SCHED_YIELD -DHAVE_MSG_NOSIGNAL -DHAVE_MSGHDR_MSG_CONTROL -DHAVE_ALLOCA_H -DHAVE_TIMEGM -DHAVE_EPOLL -DHAVE_SIGIO_RT -DHAVE_SELECT)
===========================================================
I get following errors and I am not sure which package is missing:

Answer 1

The tap.h error is due to the fact that you have enabled unit-testing support in your build, via the -DUNIT_TESTS flag in Makefile.conf. If you still want to go down this route and run the cachedb-related unit tests for MongoDB/Cassandra:
download libtap, from here
make and sudo make install
