Hello,
this report is related to
https://github.com/fplll/fplll/issues/444
The following test file round.cpp does not compile with our g++-10.2.0:
#include <cfenv>
int main () {
return std::fegetround ();
}
Compilation (also when adding "--std=c++11") prints the error:
round.cpp: In function 'int main()':
round.cpp:4:16: error: 'fegetround' is not a member of 'std'; did you mean 'fegetround'?
4 | return std::fegetround ();
| ^~~~~~~~~~
In file included from /home/andreas/.guix-profile/include/c++/fenv.h:36,
from /home/andreas/.guix-profile/include/c++/cfenv:41,
from round.cpp:1:
/home/andreas/.guix-profile/include/fenv.h:104:12: note: 'fegetround' declared here
104 | extern int fegetround (void) __THROW __attribute_pure__;
| ^~~~~~~~~~
Compilation succeeds when replacing std::fegetround by fegetround; however,
the former is supposedly part of the C++11 standard.
The culprit is apparently cfenv, which contains the following:
#if _GLIBCXX_HAVE_FENV_H
#include_next <fenv.h>
#endif
#if _GLIBCXX_USE_C99_FENV_TR1
...
#undef fegetround
...
namespace std
{
...
using ::fegetround;
...
}
Our include/c++/x86_64-unknown-linux-gnu/bits/c++config.h has this:
#define _GLIBCXX_HAVE_FENV_H 1
/* Define if C99 functions in <fenv.h> should be imported in <tr1/cfenv> in
namespace std::tr1. */
/* #undef _GLIBCXX_USE_C99_FENV_TR1 */
whereas apparently on other distributions (opensuse, for instance),
_GLIBCXX_USE_C99_FENV_TR1 is defined and leads to std::fesetround being
defined.
And when I look at the build log
https://ci.guix.gnu.org/log/xpdy9vvqym9xv7praqkwsm3gdzn2kv1p-gcc-10.2.0
for instance, there are the following lines:
checking for ISO C99 support to TR1 in <fenv.h>... no
checking for ISO C99 support to TR1 in <stdint.h>... yes
checking for ISO C99 support to TR1 in <math.h>... yes
checking for ISO C99 support to TR1 in <inttypes.h>... yes
whereas in opensuse, there is
checking for ISO C99 support to TR1 in <fenv.h>... yes
Now it would be interesting to have a look at config.log for gcc...
Andreas

I did so with gcc-10.2.0 and executed ./configure in the subdirectory
libstdc++-v3. The relevant part of config.log is this:
configure:16462: checking for ISO C99 support to TR1 in <fenv.h>
configure:16490: g++ -c -std=c++98 conftest.cpp >&5
configure:16490: $? = 0
configure:16497: result: yes
This is when trying to compile gcc-10.2.0 with gcc-10.2.0; so somehow
our bootstrapping process does something differently when creating the
final user facing gcc.

Is this perhaps related to https://issues.guix.gnu.org/42392 ?

It looks very similar indeed. But then the fix given there has not fixed
my problem, which occurs in a current gcc-toolchain.

My impression is that the root cause is the same one, that we are somehow
misconfiguring our gcc builds, as discussed in this thread:
https://lists.gnu.org/archive/html/guix-devel/2020-06/msg00096.html
And that the hacky fix works for the other problems, but apparently not
for this one.

I=E2=80=99m having a different but possibly related problem with
arm-none-eabi-nano-toolchain-7-2018-q2-update, which used to work some
time ago (in axoloti-patcher-next).
For that issue the hack also did not work.
