Gaeke <gaeke@uiuc.edu> +Subject: windows vs. llvm + +If you're interested, here are some of the major problems compiling LLVM +under Cygwin and/or Mingw. + +1. Cygwin doesn't have <inttypes.h> or <stdint.h>, so all the INT*_MAX + symbols and standard int*_t types are off in limbo somewhere. Mingw has + <stdint.h>, but Cygwin doesn't like it. + +2. Mingw doesn't have <dlfcn.h> (because Windows doesn't have it.) + +3. SA_SIGINFO and friends are not around; only signal() seems to work. + +4. Relink, aka ld -r, doesn't work (probably an ld bug); you need + DONT_BUILD_RELINKED. This breaks all the tools makefiles; you just need to + change them to have .a's. + +5. There isn't a <values.h>. + +6. There isn't a mallinfo() (or, at least, it's documented, but it doesn't seem + to link). + +7. The version of Bison that cygwin (and newer Linux versions) comes with + does not like = signs in rules. Burg's gram.yc source file uses them. I think + you can just take them out. + |
