RE: gcc4.3 configuring problems with mpfr

["Swapna Pawar" <Swapna.Pawar@kpitcummins.com>]

Hi,

I am facing the same problem as mentioned by you. Is there any solution
or workaround? Please guide.

I have successfully built the mingw native compiler with the following
sources,

mingw-runtime-3.12
w32api-3.9
binutils-2.17.50-20060824-1-src
gcc-3.4.5-20060117-1

I want to build the mingw cross compiler for m32c-elf. The sources used
for this cross
compiler are as follows:

gcc-4.3.0
binutils-2.18
newlib-1.15.0

GCC-4.3.0 requires pre-built GMP and MPFR libraries. I get the following
error
while configuring the mingw cross compiler for m32c-elf,

configure: error: Building GCC requires GMP 4.1+ and MPFR 2.3.0+.

I have used GMP 4.2.2 and MPFR 2.3.0 sources.

I have specified the paths of GMP and MPFR install directories as 
"--with-gmp=<install dir>" and "--with-mpfr=<install dir>". I tried
exporting
LD_LIBRARY_PATH also, but I still get error during configure. 
The error is as follows,

configure:4542: checking for correct version of mpfr.h
configure:4573: i386-pc-mingw32msvc-gcc -o conftest.exe -O2
-I/home/manjunathm1/gmp/prefix/include

/tmp/cc9dzbXZ.o(.text+0x4d):conftest.c: undefined reference to

Any help on this will be greatly appreciated. 

Thanks in advance.
