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. Cygwin's math.h defines log2(); it needs to be #undefed if already defined
|
|
in MathExtras.h.
|
|
|
|
6. There isn't a <values.h>.
|
|
|
|
7. There isn't a mallinfo() (or, at least, it's documented, but it doesn't seem
|
|
to link).
|
|
|
|
8. 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.
