I wrote previously about needing to hack the clang sources to build it with gcc in a non-standard location. That patch is no longer necessary, to enable it to find the GCC headers and runtime files I now configure it as:



GCC_DIR=/your/gcc/prefix

GCC_VER=4.4.3

GCC_ARCH=x86_64-unknown-linux-gnu

../llvm/configure --prefix=$PREFIX --enable-targets=host \

  --enable-optimized --disable-jit \

  LDFLAGS=-Wl,-R,$GCC_DIR/lib64 \

  --with-cxx-include-root=$GCC_DIR/include/c++/$GCC_VER \

  --with-cxx-include-arch=$GCC_ARCH



Due to some GNUisms in older versions of glibc (e.g 2.5 in my case) it's necessary to build LLVM with
make CFLAGS=-std=gnu89

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.
