Hi all,
Thanks for this awesome tool. I'm attaching three patches for
eglibc-2.12 which allowed me to target x86_64-unknown-linux-gnu-gcc
(4.5.3 and 4.6.1) on both cygwin-1.5 and 1.7 hosts. I suspect the gcc
version doesn't matter much, and probably the patches would work for
other eglibc versions as well (they're pretty minimal).
Notes:
1. gcc can't be built with lto/plugin support on a cygwin host (very
annoying to have the build fail after 2h for that reason). This might
have been fixed for gcc-4.7 but I haven't tested this on a
cross-compiler yet.
2. While building posix/cross-getconf, the error is encountered:
i686-build_pc-cygwin-gcc: command not found.
Solution: add $XTOOLS/.build/$TARGET/buildtools/bin to $PATH before
starting the build (the dir will be created as part of the build)
3. Run rebaseall before starting. Enable save states. If you encounter
fork errors while a just-built gcc is running: background the build just
after it finishes extracting the offending state, then issue the
following command (from the .build directory): rebase -sv $(find . -name
"*.dll").
Enjoy!
Ryan
