Hello,
with the following config fragment:
BR2_BINUTILS_VERSION_2_29_X=y
BR2_BINUTILS_VERSION="2.29"
BR2_BINUTILS_EXTRA_CONFIG_OPTIONS=""
BR2_PACKAGE_BINUTILS=y
BR2_GDB_VERSION_8_0=y
BR2_GDB_VERSION="8.0"
BR2_PACKAGE_GDB_ARCH_SUPPORTS=y
BR2_PACKAGE_GDB=y
BR2_PACKAGE_GDB_SERVER=y
BR2_PACKAGE_GDB_DEBUGGER=y
two versions of libbfd are installed into the target directory:
./target/usr/lib/libbfd-2.28.51.so
./target/usr/lib/libbfd-2.29.so
./target/usr/lib/libbfd.so -> libbfd-2.28.51.so
one from gdb-8.0 (2.28.51) and one from the binutils-2.29 package (and
I believe the link from libbfd.so points to the wrong one).
With the following patch (inspired by [1] found by search for
'gdb disable dynamic libbfd build'):
diff --git a/package/gdb/gdb.mk b/package/gdb/gdb.mk
index 7e86ba0..8c4188b 100644

The usual approach would be something like
ifeq ($(BR2_PACKAGE_BINUTILS),y)
GDB_DEPENDENCIES += binutils
GDB_CONF_OPTS += ... whatever is needed to make sure it uses binutils libbfd
endif
Is that an option?
Regards,
Arnout

No, I think gdb uses the bundled libbfd to avoid version problems (and I did
not find a option for using the system version).
So to get the right libbfd.so link binutils should depend on gdb, not a very
nice option...
Additional gdb/gdbserver link against the static libbfd.a, I believe the installation
of the dynamic libbfd.so version is by mistake/unneeded and I would like to avoid it,
see the ld output without my patch:
