问题
I tried to install gcc 4.5 on ubuntu 10.04 but failed. Here is a compile error that I don't know how to solve. Is there anyone successfully install the latest gcc on ubuntu? Following is my steps and the error message, I'd like to know where is the problem....
Step1: download these files:
gcc-core-4.5.0.tar.gz
gcc-g++-4.5.0.tar.gz
gmp-4.3.2.tar.bz2
mpc-0.8.1.tar.gz
mpfr-2.4.2.tar.gz
Step2: Unzip above files
Step3: move gmp, mpc, mpfr to the gcc-4.5.0/ directory.
mv gmp-4.3.2 gcc-4.5.0/gmp
mv mpc-0.8.1 gcc-4.5.0/mpc
mv mpfr-2.4.2 gcc-4.5.0/mpfr
Step4: go to gcc-4.5.0 directory and do configuration:
sudo ./configure
Step5: compile and install
sudo make
sudo make install
The first 4 steps is OK, I can configure it successfully. However, when I try to compile it, following error message comes out, I cannot figure out what the problem is. Should I change the name from "gcc 4.5" to "gcc"?? It's a little strange that we need to do this by ourself. Is there anything I missed during the installation?

回答1:
It might not be a good idea to have a space in your path - it's kind of rare and can easily mess up shell scripts that aren't specially designed to deal with it (which is a bad combination!)
Another potential problem is that you're running configure inside the gcc source directory - this isn't recommended (and didn't work at all for me on at least one version of gcc 4). Instead make an empty build directory, parallel to the source directory, so you have something like:
gcc 4.5 <- but might want to avoid the space
gcc-4.5.0
...
build
Then cd into build and run
../gcc-4.5.0/configure
You may also need to start from a freshly unzipped source directory, as the previous failed build may have broken it.
