Dear all,
I'm currently encountering an issue with the latest RTEMS toolchain (GCC
13) while attempting to build GoogleTest.
Simple example, test.cpp with the following content:
#include <sys/types.h>
#include <regex.h>
compiled with
~/quick-start/install/tools/toolchain-arm/bin/arm-rtems6-g++ test.cpp
gives me:
In file included from test.cpp:2:

Is rejecting " [__restrict] " a bug in GCC, or should the signature of
newlib`s /newlib/libc/include/regex.h be changed from
int regexec(const regex_t *__restrict, const char *__restrict,
size_t, regmatch_t [__restrict], int);
to
int regexec(const regex_t *__restrict, const char *__restrict,
size_t, regmatch_t __restrict *, int);
? I would appreciate any insights or guidance you could provide on this
matter.
I would look at the pre-processed file (for example using
-save-temps=obj). Then I would send a patch fixing the issue to the
Newlib mailing list.
