Hello,
Fedora tooling got changed [1] , probably something to do with the new gcc15.On Sun, Jan 26, 2025 at 3:48 PM Ron Olson <tachoknight@xxxxxxxxx> wrote:
--Hey all-
I’m trying to fix build failures for swift-lang on F42 and while I’ve fixed a number of places where <cstdint> wasn’t explicitly defined, I’m now getting a strange compile error regarding math.h and cmath that I can’t reproduce outside of a full build:
54 | #if __has_include(<math.h>) 55 | #include <math.h> | `- note: in file included from /builddir/build/BUILD/swift-lang-6.0.3-build/usr/lib/swift/_FoundationCShims/_CStdlib.h:55: 56 | #endif 57 | /usr/lib/gcc/x86_64-redhat-linux/15/../../../../include/c++/15/math.h:36:11: note: in file included from /usr/lib/gcc/x86_64-redhat-linux/15/../../../../include/c++/15/math.h:36: 34 | #define _GLIBCXX_MATH_H 1 35 | 36 | # include <cmath> | `- note: in file included from /usr/lib/gcc/x86_64-redhat-linux/15/../../../../include/c++/15/math.h:36: 37 | 38 | using std::abs; /usr/lib/gcc/x86_64-redhat-linux/15/../../../../include/c++/15/cmath:100:3: error: redefinition of 'acos' 98 | #ifndef __CORRECT_ISO_CPP_MATH_H_PROTO 99 | inline _GLIBCXX_CONSTEXPR float 100 | acos(float __x) | |- error: redefinition of 'acos' | `- note: previous definition is here 101 | { return __builtin_acosf(__x); }https://koji.fedoraproject.org/koji/taskinfo?taskID=128439616
What I don’t get is that it built fine before on F42/Rawhide (and uses the previously built swift rpm as part of its build process), so I guess I don’t know what changed.
Thanks for any help!
Ron
