Description Giovanni Campagna 2010-06-13 19:56:37 UTC
Created attachment 423687 [details]
Output from G++ (second example)

Description of problem:
Standard headers like <exception> or <vector> are not loadable, thus all code depending on them fails to compile.

Version-Release number of selected component (if applicable):
4.4.4-2.fc12

How reproducible:
$ echo "
#include <exception>
                 
int main() { return 42; }" | g++ -x c++ -

results in:
In file included from <stdin>:2:
/usr/lib/gcc/x86_64-redhat-linux/4.4.4/../../../../include/c++/4.4.4/exception:37:28: error: bits/c++config.h: No such file or directory
In file included from <stdin>:2:
/usr/lib/gcc/x86_64-redhat-linux/4.4.4/../../../../include/c++/4.4.4/exception:120: error: expected constructor, destructor, or type conversion before ‘(’ token
/usr/lib/gcc/x86_64-redhat-linux/4.4.4/../../../../include/c++/4.4.4/exception:142: error: expected constructor, destructor, or type conversion before ‘}’ token

$ echo "
#include <exception>

int main() { return 42; }" | g++ -x c++ -

results in a long sequence of errors (included as attachment)

Comment 1 Giovanni Campagna 2010-06-13 20:04:42 UTC
Sorry the second one had #include <vector>

Plus, I found out that, even though gcc-c++.x86_64 exists
/usr/include/i686-redhat-linux exists but not /usr/include/x86_64-redhat-linux

Comment 2 Jakub Jelinek 2010-06-13 20:20:42 UTC
That means you've installed libstdc++-devel.i686 and not libstdc++-devel.x86_64.
You need to former to compile 32-bit programs (i.e. g++ -m32), while the latter for 64-bit programs.

Comment 3 Giovanni Campagna 2010-06-13 20:38:40 UTC
Well, gcc-c++ should depend on libstdc++-devel of the appropriate architecture. as it is mostly useless on its own.

Thanks anyway.
