[LLVMdev] cross-compiling current trunk fails

[Frank Winter]

The weird thing is that I get different behavior depending on whether 
executing

make

or

make -j 10 install

after configuring. The former results in

checking whether GCC is new enough... no
configure: error:
The selected GCC C++ compiler is not new enough to build LLVM. Please 
upgrade
to GCC 4.7. You may pass --disable-compiler-version-checks to configure to
bypass these sanity checks.


the latter in the result described in the first email.

That's odd. I never had problems with a parallel build.

Ideas?

Frank
