From: "redi at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug libstdc++/109818] std::trunc() requires a <cmath> hack after building DJGPP Date: Thu, 11 May 2023 20:11:49 +0000 [thread overview] Message-ID: <bug-109818-4-NG9RLKS5lp@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-109818-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109818 --- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> --- This means djgpp is doing this: dnl To use the obsolete 'c_std' headers use --enable-cheaders-obsolete as dnl well as --enable-cheaders=c_std, otherwise configure will fail. Any idea why? As it says, the include/c_std/cmath header is obsolete, and is unmaintained and so has hardly any of the C99 <math.h> functions. The supported include/c_global/cmath header has trunc, and all the other math functions.
