Hi,
I apologise in advance if this is the wrong place to ask this question,

This is the place.
I am trying to fathom the installation procedure for gcc-core and
gcc-g++ on Windows XP and I think I must be missing something. So far I
have done the following:
- I have installed a programme called MSyS onto my machine. Which seems
to give me a posix style command line that I can run. I have installed
this in C:Program Files\msys.
- I then installed a programme called MingW32, which I believe to be a
c-compiler in binary form. Now as I understand things gcc is itself a
c-compiler, so I don't really understand why this step is needed. If
someone can compile a c-compiler elsewhere (MingW32) then why can't they
compile gcc in the same way, or am I missing something. Anyway, for
reasons I can no longer remember I installed MingW32 in a subdirectory
of the msys folder, i.e. C:Program Files\msys\1.0\mingw, I no longer
know whether this was accidental or intentional.
- I then downloaded the gcc-core.tar.bz2 and gcc-g++.tar.bz2 and copied
these into my home directory under msys, so C:Program
Files\msys\1.0\home\Luke in windows parlance, but this appears as
/home/Luke or simply ~ in msys command line.
- I unzipped them both into a gcc-4.2.0 folder, and then created a
subdirectory srcdir and moved all the unzipped files and folders into
this directory. Then made another directory objdir. So my home directory
now looks like this
/home/Luke/gcc-4.2.0
|---------- srcdir
| |-------- ...
| \-------- <all the other
files/folders from the tarballs>
|
\---------- objdir
- Then I try to run configure and I get the following error:
Luke@GODEL ~/gcc-4.2.0/srcdir
$ cd ../objdir/
Luke@GODEL ~/gcc-4.2.0/objdir
$ ../srcdir/configure loading cache ./config.cache

checking whether ln works... yes
checking whether ln -s works... no

configure: error: no acceptable cc found in $PATH
Now I understand what this is telling me. It is telling me that there is
no binary file called gcc or cc which can be used, because the path
doesn't point towards any folder that contains such a binary. But the
reason I am doing all this is to get a gcc compiler. It is all very
confusing and I would greatly appreciate any help/advice on the issue. I
have looked for a suitable gcc file under mingw32 but this didn't seem
to come with one.
I am not a mingw expert, but what you are doing looks reasonable.
GCC is written in the C programming language. In order to build it you
need a C compiler. It presents a chicken-and-egg problem if you don't
already have a suitable compiler.
I would search for pre-built GCC images for your system, and install one
of those. After you have a working GCC, you can build new versions with
that.
