Linking is another chapter that will be written after we can obtain
objects.
For the time being I am buinding a number of tests to see if the headers
are functional or not, following your suggestion to add newlib ports
header path first, and then arm-noabi-gcc header paths. I.e.
#include <...> search starts here:
/usr/local/arm-none-eabi/include
/usr/local/lib/gcc/arm-none-eabi/11.3.0/include
/usr/local/lib/gcc/arm-none-eabi/11.3.0/include-fixed
End of search list.
In this scenario the next problem I am hitting is this one:
% arm-none-eabi-gcc test_stdatomic.c -c -g -DDEBUG -pipe -nostdinc
-isystem /usr/local/arm-none-eabi/include -isystem
/usr/local/lib/gcc/arm-none-eabi/11.3.0/include -isystem
/usr/local/lib/gcc/arm-none-eabi/11.3.0/include-fixed -o
test_stdatomic.o
In file included from test_stdatomic.c:2:
/usr/local/arm-none-eabi/include/stdatomic.h: In function
'atomic_flag_test_and_set_explicit':

% cat test_stdatomic.c
#include <stdint.h>
#include <stdatomic.h>
int main(int argc, char *argv[]) {
return 0;
}
Any suggestion before I patch
/usr/local/arm-none-eabi/include/stdatomic.h to make it work?
Thank you.
BR,
