Hi Yann, all, If I build Linaro GDB as a crosstool with CT-NG 1.11.3, I get the following warning when I run GDB: "Can not parse XML target description; XML support was disabled at compile time" This may also cause errors when accessing target registers. I think that we should do something like the patch below to fix this (not yet tested). By the way, note that Linaro GCC 4.5/4.6 and GDB can now be bumped to revision 2011.05. Best regards, BenoÃt -------------------------------------------------------------------------------- This patch adds XML support to cross-gdb so that the target description can be parsed. This avoids possible runtime errors and the following GDB warning: "Can not parse XML target description; XML support was disabled at compile time" Signed-off-by: BenoÃt ThÃbaudeau <benoit.thebaudeau@advansee.com> --- --- a/scripts/build/debug/300-gdb.sh Sat May 21 14:45:04 2011 +++ b/scripts/build/debug/300-gdb.sh Sat May 21 15:08:56 2011 @@ -16,6 +16,7 @@ if [ "${CT_GDB_CROSS}" = y ]; then do_gdb=y + do_expat=y fi if [ "${CT_GDB_GDBSERVER}" = "y" ]; then @@ -100,8 +101,34 @@ if [ "${CT_GDB_CROSS}" = "y" ]; then local -a cross_extra_config + local -a gdb_cross_CFLAGS CT_DoStep INFO "Installing cross-gdb" + + if [ "${do_expat}" = "y" ]; then + CT_DoLog EXTRA "Building static host expat" + + mkdir -p "${CT_BUILD_DIR}/host-expat-build" + cd "${CT_BUILD_DIR}/host-expat-build" + + CT_DoExecLog CFG \ + "${CT_SRC_DIR}/expat-${CT_DEBUG_GDB_EXPAT_VERSION}/configure" \ + --build=${CT_BUILD} \ + --host=${CT_HOST} \ + --prefix="${CT_BUILD_DIR}/static-host" \ + --enable-static \ + --disable-shared + + CT_DoExecLog ALL make ${JOBSFLAGS} + CT_DoExecLog ALL make install + + cross_extra_config+=("--with-expat") + cross_extra_config+=("--with-libexpat-prefix=${CT_BUILD_DIR}/static-host") + # There's no better way to tell gdb where to find -lexpat... :-( + gdb_cross_CFLAGS+=("-I${CT_BUILD_DIR}/static-host/include") + gdb_cross_CFLAGS+=("-L${CT_BUILD_DIR}/static-host/lib") + fi # do_expat + CT_DoLog EXTRA "Configuring cross-gdb" mkdir -p "${CT_BUILD_DIR}/build-gdb-cross" @@ -127,6 +154,7 @@ CT_DoExecLog CFG \ CC="${CC_for_gdb}" \ LD="${LD_for_gdb}" \ + CFLAGS="${gdb_cross_CFLAGS[*]}" \ "${gdb_cross_configure}" \ --build=${CT_BUILD} \ --host=${CT_HOST} \ -- For unsubscribe information see http://sourceware.org/lists.html#faq
