(in intrepid) I clicked the gnome updater tool, as it said there were important security updates, including new kernel (working fine except for invidia drivers of course) and new gcc/g++ 4.3.2. There were around 90MB in all...
Now gcc (and g++) are broken: For example, gcc cannot find <stdio.h>
There is a stdio.h on the system (is it in the right place?)
Help! Please!
$ find /usr -name stdio.h
/usr/include/c++/4.3/tr1/stdio.h
$ uname -a
Linux xyz 2.6.27-11-generic #1 SMP Thu Jan 29 19:24:39 UTC 2009 i686 GNU/Linux
$ gcc --version
gcc (Ubuntu 4.3.2-1ubuntu12) 4.3.2
I think there must be some libc header files missing, but I can't guess which package they are supposed to be in.
synaptic lists these files installed for package libc6-dev, version
2.8~20080505-0ubuntu8(intrepid-updates) -- no header files here.
