What's the output of the following command? ls -l `which llvm-gcc`
I've become convinced that depending on llvm-gcc is the wrong way to solve this problem, as it's only going to work on systems that once had Xcode 4 installed. I have another solution that seems much more robust, and is working (inasmuch as the build has not failed). Here are the steps: 1. Start with a clean tree configured for inari (I've been running a ./build.sh clean before each test). Make sure you don't have a .userconfig. 2. Run the following commands: a. brew uninstall gcc-4.6 b. brew install --enable-cxx https://gist.github.com/artlogic/6988658/raw/aeb9d1ea098274ad3f3fe2637b9df7f308a8a120/gcc-4.6.rb The above is a minor modification of the b2g gcc-4.6 formula to enable multilibs. 3. Change HOST_CXX in build/core/combo/HOST_darwin-x86.mk to |g++-4.6|. I've actually modified mine a bit more so it works like the gcc-4.6 assignment above. Here's a diff: +HOST_CXX := g++-4.6 +ifeq (,$(wildcard /usr/local/bin/g++-4.6)) HOST_CXX := g++ +endif After this, you should be able to build as normal. This should work on ANY system, not just systems that have a stray llvm-gcc on them from Xcode 4. You've already gone above and beyond in solving this problem. If you have additional time, I'd appreciate your feedback on this technique. As an aside, I'm still having trouble flashing the images, but I believe that comes down to needing an updated boot.img, which is talked about here: http://sl.edujose.org/2013/10/adapted-boot-image-for-use-with-b2g.html - James On Tuesday, October 15, 2013 8:42:47 PM UTC-4, Christopher De Cairos wrote: > I've attempted rebuilding from scratch, changing only the HOST_CXX var > > generated in build/core/combo/HOST_darwin-x86.mk to llvm-gcc > > > > I get this build error: > > > > configure: error: Your host toolchain does not support C++0x/C++11 mode > properly.
