Hi David and the list; It would be usefull to run tests but I did this for now : I commented this at the end of your CMakeLists.txt : #if (TESTS) # enable_testing() # add_subdirectory(Test) #endif (TESTS) I'm pretty sure there is a better way to do, but that's it : I've build and installed libobjc2 on debian ppc. :-) I've got a few more questions for a complete install of gnustep on debian ppc. My goal is to have a complete script to do this, adapted from the one found on gnustep wiki found here : http://wiki.gnustep.org/index.php/GNUstep_under_Ubuntu_Linux Then I could contribute my result in it. Here are my questions : 1. Should I install libdispatch before or after libobjc2 ? I've seen this warning at the end libobjc2 install : failed to create symbolic link 'include/Block.h': No such file or directory -- Symlinking: include/Block.h -> include/objc/blocks_runtime.h failed to create symbolic link 'include/Block_private.h': No such file or directory -- Symlinking: include/Block_private.h -> include/objc/blocks_private.h 2. Should I really build and install libdispatch from Nick Hutchinson on github, as the wiki says ? I tried to build it but it fails. Can I use libdispatch from debian repo instead ? 3. If not can I install libobjc2 without libdispatch ? 4. The script on the wiki builds and install gnustep-make two times : before and after libobjc2 ? Is it still correct ? 5. For gnustep-make build, is this line still mandatory ? "git checkout `git rev-list -1 --first-parent --before=2017-04-06 master` # fixes segfault, should probably be looked at." Has this bug in gnustep-make been fixed since 2017-04-06 ? Hope someone will help here.
