How to force CB to point to the right compiler
« on: June 17, 2009, 07:06:19 pm »
Hi guys

I have a strange CB behaviour...
I'm trying to compile a piece oc C code...( source file is xxxx.c)
I have, by default, Gcc as default compiler..
So far, so good but when I launch CB, I'm getting an error 127 and a g++ not found message !!!

g++ to compile C stuff...!!!  should have been gcc instead

Something must be pointing to the wrong compiler and i'd like to know where to change it
Thks in advance

Are you sure this happens at compile-time and not in linking stage ?

g++ is used as default linker in the standard-toolchain.

To see exactly what happens, you can turn on full commandline logging:
Change "Settings -> Compiler and debugger... -> Global compiler settings -> [the compiler you use] -> Other settings(rightmost tab)" "Compiler logging" to "Full commandline".

there is a, not very obvious arrow buttons  ' <    > ' on the left and right side of the compiler settings.
tick on the > until you see the Toolchain executables tab.

Hi guys

Aaaaaaargh  !!!
The solution was, just to make CB happy, to urpmi gcc-c++..;
Once g++ is installed, then gcc is found ...
U need to install the g++ stuff, even if you don't use it, to gain access to the  compiler that u use.. pretty weird  no !!

As I wrote before, g++ is used as frontend to the linker and C::B always splits the build process in compiling and linking, so it can not work without it.

If you don't do anything but c-compiling and you absolutely don't want to install g++, you can use gcc for linking stage.
gcc can link c-files, but not c++-files, g++ can link both of them.
