llvm dev - Apr 2009 - [LLVMdev] SVN Head Error Building on Mac OS X

Dear All,

Has anyone else noticed the following problem building LLVM on Mac OS X:

find-cycles.pl: Circular dependency between *.a files:
find-cycles.pl:   libLLVMAsmPrinter.a libLLVMCodeGen.a libLLVMSelectionDAG.a
llvm[1]: Building llvm-config script.
cat: /Users/criswell/box/x86/llvm22/tools/llvm-config/FinalLibDeps.txt:
No such file or directory

I managed to fix this by deleting nearly all of the files in my object
tree, reconfiguring, and rebuilding.

Does anyone know exactly which file I deleted that fixed this?

No, but I've seen this before and know "make clean" fixes it.

FYI, to speed up the "make clean; make" cycle, consider using ccache:
http://ccache.samba.org/ .

It will also speed up your development should you choose to have 2+ LLVM
trees in which you might be working on separate changes (to keep one working
while you implement the other one) -- it will let you share the common
object files between the trees so you don't have to build everything all the
time, just what changed.
