When building g++ from the gcc 3.0 release, std_cwhar.h fails to compile:

-----------------

These are the steps I performed:

 

download gcc-core-3.0.tar.bz2

unpack

run configure:

  cd build

 

 

../gcc-3.0/configure --prefix=/home2/usr/gcc-3.0 --enable-version-specific-r

untime-libs --enable-threads --enable-threads=single

 

  make bootstrap

 

**> gcc-core built fine.

I read somewhere that you need gcc 3.0 to build libstdc++-v3

So I did this:

make install

cd /usr/bin

rm gcc    [ this was a softlink ]

ln -s /home2/usr/gcc-3.0/bin/gcc .

 

 

Next, I got gcc-g++-3.0.tar.bz2 and unpacked it and then did:

 

cd build

make clean

 

 

../gcc-3.0/configure --prefix=/home2/usr/gcc-3.0 --enable-version-specific-r

untime-libs --enable-threads --enable-threads=single

 

  make bootstrap

 

The errors from above pop out in this part.

 

System info

Linux kernel 2.2.4

Mandrake 7.2 distribution

(original) gcc 2.95.3

 

?????

 

Thanks.
