What steps will reproduce the problem? 1. Attempt to perform the whole process on the "Building" wiki page. 2. Discover that llvm-svn revision 42498 is unbuildable with g++ 4.3.2 as-is, painstakingly add #includes one-by-one until build succeeds. 3. Attempt to download my iPhone's filesystem using scp, only to discover that you can't copy some of the stuff in the /dev directory, and scp follows all the symlinks on the phone resulting in multiple copies of the same stuff. End up copying over directories one-by-one, making sure to avoid the symlinks and recreate them manually. Ignore the Media directory, as it contains about 30 gigs of music and pictures which are not needed. 4. Discover that an old xcode 2.4 or 2.5 DMG is needed to extract MacOSX10.4.Universal.pkg, NOT the current version on Apple's website (3.1.2). After figuring that out, I was able to extract the pkg using the instructions in the comment by PhireN. "HOWTO obtain the Mac OSX headers" really should mention this. 5. Attempt to build llvm-gcc-4.0-iphone. Build fails with "* buffer overflow detected *" on arm-apple-darwin-ranlib. Attempt to "plow through it" as suggested by several comments... running 'make' over and over and getting a little farther each time. Finally the build fails with "load command 7 unknown cmd field". 6. Follow the steps in Comment 2 of Issue 153, which include: - Switching over 'include' and 'odcctools' repositories for updates - Patching lib1funcs.asm 7. Rebuild llvm-svn and odcctools again from scratch. 8. Attempt to build llvm-gcc-4.0-iphone again. Again, "plow through" the buffer overflow errors by rerunning make over and over. Before, the "unknown cmd field" error appeared after only 4 makes. This time I'm getting much farther, which leads me to believe that the updates or the patches had SOME effect. 9. Run into a brick wall after rerunning make 12 or 13 times. The build still fails on the ranlib "buffer overflow" each time, but it seems to have stopped making any forward progress. The last thing I see every time before the buffer overflow is: file: .libs/libsupc++convenience.a(eh_arm.o) has no symbols

What is the expected output? What do you see instead? Expected output: A successful build. Actual output: ranlib "buffer overflow" error in the build process that multiple 'make's won't cure.

What version of the product are you using? On what operating system? - Kubuntu 4.10 - iphone-dev SVN as of April 12, 2009

Please provide any additional information below.

What version of gcc/g++? I got the buffer overflow messages while using gcc/g++ 4.3. I downgraded to 4.2 and it all compiled just fine! Try that (don't forget to change the gcc/g++ symlinks to point to 4.2 instead of 4.3).

Indeed, I'm using gcc 4.3.2 that comes with Kubuntu 4.10. In the meantime, I've started down this path: http://code.google.com/p/iphonedevonlinux which is a lot newer and looks custom-made for Linux. If it doesn't work I'll certainly come back to this method and try to rebuild everything with gcc 4.2. Thanks for the advice!
