I tried building devel/llvm-devel having the ports tree attached on a = fast USB disk. After 36 h of building it bailed out because of some = obscure error in the AArch64 code generator. Finally, I don't think that building any LLVM port is viable on the BBB, = first because building takes forever. The BBB needs 1 minute for = compiling a C++ file which got only 20 lines of code. Of course this = comes because the C++ experts tend for some ingenious reasons to hide = all the implementations into the headers which need then to be compiled = again and again. Second, it doesn't make sense at all to build LLVM for = all the possible targets on a machine which I will never ever use for = cross-development. I will now try a non-ports build of LLVM 3.91 for the armv6 target only. Best regards Rolf
