Error while building GCC 4.5 (MinGW)

Error while building GCC 4.5 (MinGW)

[Name lastlong]

Hi,

I am trying to build a toolchain for gcc-4.5-20100401 snapshot.
The linux toolchain was built successfully as expected.

However, on building the mingw toolchain, it generated the following error
while configuring gcc:-

=============================error================================
checking for the correct version of the gmp/mpfr/mpc libraries... no
configure: error: Building GCC requires GMP 4.2+, MPFR 2.3.1+ and MPC 0.8.0+.
============================ error================================

The following commands were used to build the precision libraries.
./gmp-4.2.2/configure  --host=mingw32 --target=mingw32 --build=i686-pc-linux-gnu --prefix=$prefix
./mpfr-2.3.1configure  --host=mingw32 --target=mingw32 --build=i686-pc-linux-gnu --with-gmp=$prefix --prefix=$prefix
./mpc-0.8/configure 
 --host=mingw32 --target=mingw32 --build=i686-pc-linux-gnu --with-gmp=$prefix --with-mpfr=$prefix --prefix=$prefix

The LD_LIBRARY PATH was also exported to $PREFIX PATH.
However, the error was not resolved. This error is due to the addition of MPC library  dependency.

Please let me know whether its a known problem OR I am missing anything while building the libraries?

Regards,
Brew

Check the config.log file for details.  A successful build should show 
something like this
configure:5634: checking for the correct version of the gmp/mpfr/mpc 
libraries
configure:5665: gcc -o conftest -g -O2    conftest.c  -lmpc -lmpfr -lgmp >&5
configure:5665: $? = 0
configure:5666: result: yes

Your file should have an error here.

Thanks for the prompt reply and suggestions.
I checked the config.log as per your suggestion.

Please check the following relevant information present in the config.log 
as follows:

Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations.  Source code for these libraries can be found at
their respective hosting sites as well as at
ftp://gcc.gnu.org/pub/gcc/infrastructure/.  See also
http://gcc.gnu.org/install/prerequisites.html for additional info.  If
you obtained GMP, MPFR and/or MPC from a vendor distribution package,
make sure that you have installed both the libraries and the header
files.  They may be located in separate packages.
================================= config.log ==========================

The mingw toolchain was successfully built with earlier 
versions(gcc-4.5-20091105).
However, the above problem is faced after introduction of "MPC" libraries.

Please let me know if there are any particular steps to be followed to build 
mingw toolchain with mpc libraries.

Regards,
Brew

Now that you can see what is wrong, you should try to manually reproduce
the error.  Check the libraries to see if they are OK, and if the right
versions of the libraries are being linked in.  Look to see where the
undefined references are coming from.  Etc.

I have no idea.  I haven't built a mingw toolchain anytime recently.

  This just looks like your mpfr and mpc libraries are completely busted.  Cut
and paste the command-line into a shell, and add "-v -Wl,-v -Wl,-Map,out.map".
 Take a look at the linker output and make sure it's linking against the mpc
and mpfr library files that you expect it to be; take a look at those files
with "nm" to see what symbols they define.

  This is /probably/ not a GCC bug, so maybe we should move it to the gcc-help
list if something doesn't show up in the next round or two of debugging.

    cheers,
