| 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. |
