[klee-dev] klee-uclibc not compiling

[Double Dave]

Thanks Dan,

that helped me a little bit, but then i ran into more errors.

Eventually i could compile klee-fp by following the official klee instructions,  rather than the klee-fp instructions. 
I only had to change the  "# LLVM Capable Compiler" part in the Makefile.rules , to this https://llvm.org/viewvc/llvm-project/llvm/trunk/Makefile.rules?diff_format=h&revision=96935.

Hi Dave,

I don't support that particular variant of klee-uclibc. However you
can probably change the architecture of the build by doing...

$ cd /path/to/root/of/klee-uclibc
$ make menuconfig

Now change the configuration so that the architecture is i386 instead
of x86_64 . This should change a hidden file ".config".

Now clean out the old build files and re-compile.
$ make clean
$ make

Hope that helps.

Thanks,
Dan Liew.
