libstdc++ 64bit and 32bit version on the same machine
I am trying to cross compile a version of my software for a 64bit platform. Can I have the 32bit and 64bit version of libstdc++ installed on the same machine without too much worries of breaking my linux install. The Os is 32bit ubuntu.
I have not cross compiled before and just wanted to check that if I set my CFLAGS and LDFLAGS for the appropriate CPU I should be ok once I have the correct versions of libstdc++ installed.
I checked a 64bit version of ubuntu however this has a symbolic link
lib64 -> lib
this would mess up lots if this is the case on a 32bit machine too anyone know how to sort this?
I am hitting the following error at the moment
[exec] /usr/bin/ld: skipping incompatible /usr/lib/gcc/i486-linux-gnu/4.2.4/libstdc++.so [exec] /usr/bin/ld: skipping incompatible /usr/lib/gcc/i486-linux-gnu/4.2.4/libstdc++.a when searching for -lstdc++ [exec] /usr/bin/ld: skipping incompatible
and so on till
[exec] /usr/bin/ld: cannot find -lstdc++ [exec] collect2: ld returned 1 exit status
Which seems to be due to fact I do not have the 64bit version of libstdc++
Sure you can.
Just put them into /usr/lib and /usr/lib64, respectively.
Can't check it on Ubuntu, but on Fedora they get there right from the packages:
[~#] repoquery -q -l libstdc++.i386 /usr/lib/libstdc++.so.6 /usr/lib/libstdc++.so.6.0.10 [~#] repoquery -q -l libstdc++.x86_64 /usr/lib64/libstdc++.so.6 /usr/lib64/libstdc++.so.6.0.10
