Hello folks. If you compiled and installed GCC 4.6 and during the Android Gingerbread (or another software) compilation you received the following error message: “libstdc++.so.6: wrong ELF class: ELFCLASS64″.
Don’t worry about that. You are just using a wrong architecture of the libstdc++.so.6 in the folder /usr/lib32 in Ubuntu 64 bits. To solve that, open a terminal, go to the place where you have built GCC 4.6 and run the commands below:
sudo cp build/x86_64-unknown-linux-gnu/32/libstdc++-v3/src/.libs/libstdc++.so.6.0.16 /usr/lib32
cd /usr/lib32
sudo rm libstdc++.so.6
sudo ln -s libstdc++.so.6.0.16 libstdc++.so.6
sudo ln -s libstdc++.so.6.0.16 libstdc++.so
sudo ldconfig
Doing that, we copied the libstdc++.so.6 for 32 bits in /usr/lib32 and also updated the links to this one. Now, all software that need this lib for 32 bits will use this one for compilation.
Remember, the lib libstdc++.so.6.0.16 is the version when I compiled GCC 4.6. If you get the file recently, this version will be different. Just don’t forget to change the reference to this one.
That’s it. See you next time.
