../../gcc-4.7.1/libiberty/fibheap.c:220:30: error: 'LONG_MIN' undeclared (first use i
 

Hi,

When I tried to compile gcc4.7.1 at pass 2, everything was fine, but I got struck up with this error...

lfs@boss:/media/LFS/sources/gcc-build$ make

kindly help me out of this....

It means that either the define or the variable LONG_MIN is undeclared in your build environment. You need to fix this before you can continue your build.

Do an Internet search. Lots of information available about this particular problem.

My first guess: the programmer forgot to #include limits.h into fibheap.c

[solved]
 

Hi,

Friends very much thank for your dynamic replies,

I solved this problem, by just deleting the build directories(which I created) of various packages, which I installed before this package...
