when cross compilling native gcc (host == target, build != host )
sdt.h is looked up in build system's include directory, rather then in
sysroot of cross compiler:
in gcc/configure.ac:
...
# Test for <sys/sdt.h> on the target.
GCC_TARGET_TEMPLATE([HAVE_SYS_SDT_H])
AC_MSG_CHECKING(sys/sdt.h in the target C library)
have_sys_sdt_h=no
if test -f $target_header_dir/sys/sdt.h; then
have_sys_sdt_h=yes
AC_DEFINE(HAVE_SYS_SDT_H, 1,
[Define if your target C library provides sys/sdt.h])
fi
AC_MSG_RESULT($have_sys_sdt_h)
...
when target == host $target_header_dir is empty
how can I workaround this ?
