Gaeke <gaeke (a] uiuc.edu> 3 Subject: windows vs. llvm 4 5 If you're interested, here are some of the major problems compiling LLVM 6 under Cygwin and/or Mingw. 7 8 1. Cygwin doesn't have <inttypes.h> or <stdint.h>, so all the INT*_MAX 9 symbols and standard int*_t types are off in limbo somewhere. Mingw has 10 <stdint.h>, but Cygwin doesn't like it. 11 12 2. Mingw doesn't have <dlfcn.h> (because Windows doesn't have it.) 13 14 3. SA_SIGINFO and friends are not around; only signal() seems to work. 15 16 4. Relink, aka ld -r, doesn't work (probably an ld bug); you need 17 DONT_BUILD_RELINKED. This breaks all the tools makefiles; you just need to 18 change them to have .a's. 19 20 5. There isn't a <values.h>. 21 22 6. There isn't a mallinfo() (or, at least, it's documented, but it doesn't seem 23 to link). 24 25 7. The version of Bison that cygwin (and newer Linux versions) comes with 26 does not like = signs in rules. Burg's gram.yc source file uses them. I think 27 you can just take them out. 28 29
