Hi all,
I'm trying to make system call or spawn using GNAT.OS_lib. Both results in undefined reference to __fentry__. What am I missing?
Regards,
Petter

Check the linker options; it looks like the entry isn't being picked up.
(I think it's something like -L[lib-name].)

Googling __fentry__ finds
https://unix.stackexchange.com/questions/259591/linux-kernel-missing-fentry-symbol,
don't know if that's any use

Hi Peter
I am using msys2/mingw64 FSF 8.1 on windows 10 and the below sample works fine
(ie I get the "cmd /?" output in my debug window, note I am using my
Visual studio ada addin, called "Visual Ada") Note However that the Success
output parameter comes back as false! Not sure why. But it does seem to work.
Alex
--------------------------------------------------------------------------------
with GNAT.os_lib;
--------------------------------------------------------------------------------
procedure ConsoleApp1 is
Args : GNAT.os_lib.argument_list(1..1) := ( others => new string(1..2) );
Success : Boolean;
begin
Args(1).all := "/?";
GNAT.os_lib.spawn("cmd", Args, Success);
end;

Because cmd /? sets ERRORLEVEL to 1, which is then reflected in Success.

Hi all,
Profiling is not supported on 64 bit windows, that was the problem.
Regards,
Petter
