Hello,
I encountered a problem today with the =g++= compiler from the
package =gcc-toolchain=. When compiling a simple hello world
program:
#+begin_src c++
#include <iostream>
int main () {
std::cout << "Hello World\n";
return 0;
}
#+end_src
with:
#+begin_src bash
g++ hello.cc
#+end_src
I have the following errors, tracing back to the =iostream.h=
file:
#+begin_example

Is it a bug, or am I doing something wrong here ?
Thanks a lot for your help !

When I try to compile your source code using
guix shell -C gcc-toolchain -- g++ x.cpp
it does work. Could you try it as well to check whether it will work at least
in a pure environment?
Have a nice day,

cache invalidation, naming things and off-by-one errors.

That also works for me. If, however, I also include
=gfortran-toolchain= in the mix
guix shell -C gcc-toolchain gfortran-toolchain -- g++ x.cpp
then I come back to the same error as before.
So, is there an incompatibility between both packages ?
Thanks for your answer and your help !

I found out the problem: =gfortan-toolchain= is at version
=11.3.0=, while =gcc-toolchain= is at =13.2.0=. Using:
guix shell -C gcc-toolchain@11.3.0 gfortran-toolchain -- g++
x.cpp
works as expected, without any error.

I found out the issue: =gfortran-toolchain= corresponds to GCC
11.3.0, while =gcc-toolchain= corresponds to version
13.2.0. Using:
guix shell -C gcc-toolchain@11.3.0 gfortran-toolchain -- g++
x.cpp
now works without errors.
