Hi

I cannot compile simple c++ packages I install gcc-c++ but I get the error message when configuring

"configure: error: Your Installation isn't able to compile simple C++ programs.
Check config.log for details - if you're using a Linux distribution you might miss-"

(the text is cut off at miss)

Probably a $PATH error. Did you look at the config.log file for the details? What did it say?

Edit: Also, why is this posted in "General" instead of "Programming?"

Here is my config.log

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.59. Invocation command line was

Does running make distclean help (as suggested at the end of the log-file.
Maybe it's a package that TS want's to install

how do I run distclean?

What Wim Sturkenboom suggested was to run "make distclean", not "distclean".

I tried installing again and it says i need libstd++-dev

Then download the -devel (development) version of libstd++.
libstd++ is the standard C++ library. Installing the "-devel" extension just
gives you the header files (include files) you'll need to develop code
using libstd++.

In other words, without the -devel extension, you don't get to
#include some_part_of_libstd++
You can only use programs that are dynamically linked to the lib.
