That might be useful. I followed David's suggestion, but still getting an issue.
[100%] Built target objc_msgSend_optimised Installing libraries... install: cannot stat `.so.': No such file or directory make: *** [install] Error 1 That's when I do make install (the build is successful). Apparently nothing gets copied in /usr/local/lib (where it was going with the tarball build). I'm building llvm from source now just in case. If that does not pan out, I'll try KitKit. -- Laurent On Mar 6, 2013, at 7:17 AM, Charalampos Chrysovalantis Emmanouilidis <[email protected]> wrote: > You may want to give KitKit a try, if you need to write ObjC2.0 code on linux > > https://github.com/cemmanouilidis/kitkit > > KitKit provides an ObjC2.0-environment using clang, cmake, gnustep-base and > gnustep-libobjc2 (please note, there is not gui support yet, but this is easy > to add.
