I tried building clangbsd yesterday with clang/llvm r104146 and it worked
ok.
and it still does:
pes ~/clangbsd$ clang --version
clang version 2.0 (trunk 104146)
Target: x86_64-unknown-freebsd8.0
Thread model: posix
pes ~/clangbsd$ clang -c lib/libc/stdlib/malloc.c -I lib/libc/include/ -DMAXPAGESIZES=1 && echo success
lib/libc/stdlib/malloc.c:5408:12: warning: implicit declaration of function 'getpagesizes' is invalid in C99
[-Wimplicit-function-declaration]
nsizes = getpagesizes(pagesizes, MAXPAGESIZES);
^
1 warning generated.
success
can you retry with newer version? or show me how exactly to reproduce this?
