Bug ID: 79903
Summary: When building RTEMS for SPARC with Ada support, the
build fails because of missing #ifdef
Product: gcc
Version: 6.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
Assignee: unassigned at gcc dot gnu.org
Reporter: ttsiodras at gmail dot com
Target Milestone: ---
I have just successfully built the latest GCC cross-compiling toolchain for
RTEMS/SPARC with Ada support - but to do so, I had to patch the GCC 6.3 source
in one place:
diff --git a/gcc-6.3.0/gcc/ada/socket.c b/gcc-6.3.0/gcc/ada/socket.c
index f5fb663..5cdd656 100644
--- a/gcc-6.3.0/gcc/ada/socket.c
+++ b/gcc-6.3.0/gcc/ada/socket.c
@@ -202,7 +202,7 @@ __gnat_gethostbyaddr (const char *addr, int len, int
type,
struct hostent *rh;
int ri;
-#if defined(__linux__) || defined(__GLIBC__)
+#if defined(__linux__) || defined(__GLIBC__) || defined(__rtems__)
(void) gethostbyaddr_r (addr, len, type, ret, buf, buflen, &rh,
h_errnop);
#else
rh = gethostbyaddr_r (addr, len, type, ret, buf, buflen, h_errnop);
Without that patch, the RTEMS RSB build fails - at least for the following
version of the RSB:
$ # RTEMS Source Builder: commit 4c5eb8969451c4ea0997b3caa98bfe80fe15da69
$ ../source-builder/sb-set-builder --log=sparc2.log
--prefix=/opt/rtems-4.12 --without-rtems --with-ada 4.12/rtems-sparc
Hope this helps.
Kind regards,
Thanassis.
