Fwd: Re: GCC-4-3.2 Build /Possible configuration problems

[Franklyn Simon]

Hi,

This is what I did:

I. Unpacked sources
1. # mkdir /opt/gcc-4.3.2
2. Under /opt/gcc-4.3.2, I unpacked the gcc sources
3.  Both gmp, mpfr. And binutils are unpacked under /opt/gcc-4.3.2

II. Build and configure
    * build and configure binutils under 
/opt/build_binutils using /usr/local/gcc-4.3.2 as prefix
    * build and configure gmp and mpfr in their 
directory /opt/gcc-4.3.2/gmp and 
/opt/gcc-4.3.2/mpfr using  /usr/local/gcc-4.3.2 as prefix

III. GCC-4.3.2

    * Configure and build in /usr/local/gcc-4.3.2 as follows
    * # cd /usr/local/gcc-4.3.2
    * /usr/local/gcc-4.3.2 # 
/opt/gcc-4.3.2/configure –prefix=/usr/local/gcc-4.3.2 etc
       4. /usr/local/gcc-4.3.2 # make    --- this went it failed

My understanding:

The prerequisites for GCC indicate that both gmp 
and mpfr will be built together with GCC if they 
are subdirectories of the GCC sources.  I tried 
that but had problems since gcc did not know 
where to get gmp.h amd mpfr.h and their 
libraries.  However, when I configured and 
compiled both of them it their source directories 
using /usr/local/gcc-4.3.2 as prefix, I did not 
have that problem.  Both gmp and mpfr have 
information about how to configure and build 
which do not seem to be in parallel with the gcc 
instllation found on 
<http://gcc.gnu.org/install/>http://gcc.gnu.org/install/. 
I do not think a really understand about building 
gmp and mpfr together with gcc.

Please further advise me of what I am doing wrong.

Thanks to all
