Please try the most recent release (1.8.1, see: https://github.com/gnustep/libobjc2/releases ), which incorporates some more error checking and recovery into the build process (not to mention a number of other bug fixes). > mkdir Build; cd Build; cmake .. -DCMAKE_C_COMPILER=clang > -DCMAKE_CXX_COMPILER=clang++ > > This resulted in the following error: > > -- Untested version of LLVM (3.8.0svn) found. > -- Disabling LLVM options unless explicitly enabled. > -- No C++ runtime library found > -- GNUstep install type set to NONE > CMake Error at CMakeLists.txt:310 (install): > install TARGETS given no LIBRARY DESTINATION for shared library target > "objc". > > > -- Configuring incomplete, errors occurred! > See also "/home/dlobron/clang/libobjc2-1.7/Build/CMakeFiles/CMakeOutput.log". > See also "/home/dlobron/clang/libobjc2-1.7/Build/CMakeFiles/CMakeError.log". > > I worked around this by simply running "make; make install".

The correct install sequence is: 1) Build and install libobjc2. If you are on a GNU/Linux platform, you probably want to set the default prefix to /usr (not /usr/local). 2) Install GNUstep-make 3) Install GNUstep-base (and any dependencies) 4) Install GNUstep-gui For reference on packaging, I’d suggest looking at the FreeBSD ports, which build packages providing a modern GNUstep environment.
