linux gcc compilation CROSSTOOL prompt how to do, I believe that many inexperienced people are helpless, for this reason this article summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

I am currently using Ubuntu 8.04, because recently has been upgrading Linux, resulting in my current Linux gcc version has also become higher, is currently 4.2.3. When I compile the CROSSTOOL I had previously, I get this prompt:

checking for a BSD-compatible install... /usr/bin/install -c

checking whether ln -s works... yes

checking for pwd... /bin/pwd

checking for arm-linux-gcc... gcc

checking version of gcc... 4.2.3, bad

checking for gnumake... no

checking for gmake... no

checking for make... make

checking version of make... 3.81, ok

configure: error:

*** These critical programs are missing or too old: gcc

*** Check the INSTALL file for required versions.

So I need to press my current version of linux gcc to the previous state 3.4. First of all, you need to go to your usr/bin/to see if there is a file like gcc-3.4, if not, install it:

apt-get install gcc-3.4

After that, you need to delete the gcc file in usr/bin/directory or avoid accidents, you can name it gcc.bak. If you don't delete it, you'll find that ln -s usr/bin/gcc-3.4 /usr/bin/gcc doesn't work. In fact, when you use gcc -v to check the current version, you always use usr/bin/gcc. ln -s /usr/bin/gcc-3.4 /usr/bin/gcc is intended to generate gcc version 3.4. In a word, you just need to execute:

rm /usr/bin/gcc

ln -s /usr/bin/gcc-3.4 /usr/bin/gcc

And then gcc -v you can see that the current version is 3.4. If you want to reuse the current 4.2.3, use the same method:

rm /usr/bin/gcc

ln -s /usr/bin/gcc-4.2.3 /usr/bin/gcc

Then gcc -v to determine the version will know.
