Hi all,
I'm having another issue with the clang toolchain right now and I've come up
with a minimal reproducer:
Given the following manifest.scm:
--8<---------------cut here---------------start------------->8---
(use-modules (gnu packages gcc)
(gnu packages linux)
(gnu packages llvm))
(packages->manifest
(list clang
(make-libstdc++ gcc)
linux-libre-headers))
--8<---------------cut here---------------end--------------->8---
And test.cpp:
--8<---------------cut here---------------start------------->8---
#include <mutex>
#include <iostream>
typedef std::once_flag once_flag;
int
main()
{
std::cout << "Hello, World\n";
}
--8<---------------cut here---------------end--------------->8---
If you invoke:
--8<---------------cut here---------------start------------->8---
guix environment --manifest=manifest.scm --container --pure -- clang++ test.cpp
--8<---------------cut here---------------end--------------->8---
The output looks like:
--8<---------------cut here---------------start------------->8---
test.cpp:4:14: error: no type named 'once_flag' in namespace 'std'
typedef std::once_flag once_flag;
~~~~~^
1 error generated.
--8<---------------cut here---------------end--------------->8---
In my original non-minimal build, other things in <mutex> also cause compilation
errors, which seem odd to me.
Any help would be very much appreciated!
Cheers,
