errors out on OS X 10.10.4 with "clang: no input files" #8

Closed kubatyszko closed 8 years ago

I traced it to the:

as -L /tmp/jit_out.s -o /tmp/jit_out.o"

call, and concluded that my as didn't like the "-L" argument. After removing it and recompiling it the sledge works.

(it still throws me a segfault when trying to run the GUI but I'll leave that for another day)

What kind of "as" do you have exactly? I added -L specifically for OS X compatibility, to make sure that local labels end up in the object's symbol table. If they do not, functions and branches et cetera won't work.

Apple LLVM version 7.0.0 (clang-700.0.72) Target: x86_64-apple-darwin14.4.0 Thread model: posix "/Library/Developer/CommandLineTools/usr/bin/clang" -cc1as -triple x86_64-apple-macosx10.10.0 -filetype obj -main-file-name - -target-cpu core2 -fdebug-compilation-dir /Users/kuba -dwarf-debug-producer Apple LLVM version 7.0.0 (clang-700.0.72) -o a.out -

Standard "as" from OS X, didn't touch anything

I didn't investigate the issue very deeply but when I use "-L" the clang complains about input files, it might have something to do with order of arguments. .... And now I tried different order, and this call:

as -o /tmp/jit_out.o /tmp/jit_out.s -L

seems to work better (but throws a warning: "clang: warning: argument unused during compilation: '-L-integrated-as'")

Ok, finally have time to boot OSX and fix this. For the record, I currently have Yosemite 10.10.5 and "as" is /usr/bin/as, "Apple Inc version cctools-870, GNU assembler version 1.38".

@kubatyszko I changed the OSX version now to force clang to use the system as (not the integrated one). This works on my system but I'm curious what happens on yours!

kubatyszko commented 8 years ago

@mntmn it works well now. I'm on 10.10.4, my as is:

as --version Apple LLVM version 7.0.0 (clang-700.0.72) Target: x86_64-apple-darwin14.4.0 Thread model: posix

Thanks
