It seems that tgmath.h is not available on Darwin: $ gcc-dp-4.2 -std=gnu99 -Wall -o complex complex.c complex.c:3:20: error: tgmath.h: No such file or directory
$ gcc-dp-4.2 --version gcc-dp-4.2 (GCC) 4.2.0 20060729 (experimental) There is no file tgmath.h provided with the compiler that could be installed (I checked revision 120754). There is a file tgmath.h that ships as part of libstdc++, but this is only a C++ wrapper. tgmath.h exists in glibc, but my system does not use glibc. Naively trying to use this file leads to a syntax error on the line containing #if __GNUC_PREREQ (2, 7) I found a discussion on the gcc mailing list from August 2004 which discusses this topic: <http://gcc.gnu.org/ml/gcc-patches/2004-08/msg00918.html>. Apparently there was a somewhat heated discussion on whether it would be useful or appropriate to include tgmath.h with the compiler. Since my operating system does not have a tgmath.h, I would like to argue that gcc should "fixinclude" it by providing a fallback implementation. By the way, <http://gcc.gnu.org/c99status.html> marks tgmath.h as "done". -- Summary: tgmath.h not found Product: gcc Version: 4.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: schnetter at aei dot mpg dot de GCC build triplet: i386-apple-darwin8.7.1 GCC host triplet: i386-apple-darwin8.7.1 GCC target triplet: i386-apple-darwin8.7.1 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30456
