Yes (I already reviewed it when it arrived upstream). It is probably also safe to backport to GCC-11 since there's no ABI or ABI stability concerns.

[Bug 1933775]
There's no easy solution. Intel contributed the PSTL headers with a dependency on TBB task.h header, then deprecated that header in a later TBB release. You need to either use an older TBB, or suppress the warning. There is a plan to add an OpenMP backend to PSTL, which will remove the TBB dependency, but it's not ready yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1933775 Title: libgcc-s1 and libstdc++6 depend on broken libtbb2 package To manage notifications about this bug go to: https://bugs.launchpad.net/gcc/+bug/1933775/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

No, the gcc packages don't depend on any tbb package.

requires TBB, as documented: https://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.2017 "Note 3: The Parallel Algorithms have an external dependency on Intel TBB 2018 or later. If the header is included then -ltbb must be used to link to TBB." If you use the parallel algos (or just include their headers) then the TBB headers are included. That's by design, they don't work otherwise. We can't do anythign about the fact that Intel deprecated their own API shortly after using contributing the PSTL headers to GCC, which depend on that API. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1933775 Title: libgcc-s1 and libstdc++6 depend on broken libtbb2 package To manage notifications about this bug go to: https://bugs.launchpad.net/gcc/+bug/1933775/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've managed to reproduce this issue on two different machines, one
amd64 and the other ppc64le. Both were using g++-11 (Ubuntu

Here is a minimal:
#include
#include
using namespace std;
int main()
{
vector Container(3'000'000);
iota(begin(Container), end(Container), 1);
sort(execution::par, begin(Container), end(Container));
return 0;
}
Compiling raises the following pragma in header generated warning:

Compiling again with #define TBB_SUPPRESS_DEPRECATED_MESSAGES 1
prepended to the beginning and the warning disappears.
This appears to have crept in some how with the 11 series. The
header is indirectly including some deprecated Intel header
from the TBB library.

It depends on the version of TBB that is installed really. Looks like
Ubuntu 11.1.0 is using a much newer version. You really should file a
bug with Ubuntu about this issue since you are getting both GCC and TBB
from them. We won't fixing Ubuntu's compiler even with this bug filed
by the way.
