clang++ fails with fatal error: 'bits/c++config.h' file not found
Last modified: 2011-04-22 07:02:15 EDT
Description of problem:
Attempting to compile:
using namespace std;
cout << "Hello World!\n";
with clang++ results in:
$ clang++ test.cpp
In file included from test.cpp:1:
/usr/include/c++/4.6.0/iostream:38:10: fatal error: 'bits/c++config.h' file not found
1 error generated.
Version-Release number of selected component (if applicable):
Happens on both Fedora 14 and Fedora 15. I guess they both have clang 2.8.
I remember than on F14 symlinking /usr/include/c++/4.5.1/i686-redhat-linux to i386-redhat-linux in the same directory helped, but this trick doesn't work with F15 and gcc 4.6.0.
I'm not seeing this on x86_64.
Yes, it looks 32-bit only, it's searching for /usr/include/c++/4.6.0/i386-redhat-linux/32. Let me see if I can come up with a patch.

It's listed as fixed here: http://koji.fedoraproject.org/koji/buildinfo?buildID=235848
However, the issue still persists on 32-bit. I will post the details in other bug.
