I am trying to build gcc-4.7.2 (September tarball release) on Ubuntu 12.04.
Some ways into the build I get the following error processing the libgomp directory:
make[3]: Entering directory `/a/home/tbird/work/auto-reduce/lto-work/obj-gcc/x86_64-unknown-linux-gnu/libgomp'

Has dependency-handling changed recently in this directory?
There is no .deps directory in libgomp. Examining the
Makefile, it is not obvious how these files are supposed
to be generated.
My configure invocation was:
../gcc-4.7.2/configure --prefix=/opt/gcc-4.7 -enable-lto \
--with-plugin=ld=/usr/local/bin/ld-plugin --disable-nls \
--enable-languages=c,c++ --disable-libstdcxx-pch
Can anyone give me some tips for debugging this?
I had originally done a parallel build. Based on some previous gcc
bug reports, I tried a 'make clean' and a serial build
('make' with no '-jx').
But I still get the same thing.
Any ideas would be appreciated.
Thanks,
