Re: new plugin bfd_target breaks gdb with --enable-targets=all


Hi Rafael,

Would that new version make sure we're not building plugin.c with
--enable-targets=all on non -ldl, non dlopen targets? Â E.g., mingw.
A quick lookaround Makefile.am didn't spot where that is prevented in
the current sources.

It should, yes. It is in http://sourceware.org/ml/binutils/2009-05/msg00359.html

But that only works when --enable-plugin is used. If you build a toolchain with --enable-target=all but without --enable-plugin then you get:


libtool: link: gcc -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Werror -g -O2 -o size size.o bucomm.o version.o filemode.o ../bfd/.libs/libbfd.a ../libiberty/libiberty.a -lz
../bfd/.libs/libbfd.a(plugin.o): In function `try_load_plugin':
.../bfd/plugin.c:127: undefined reference to `dlopen'
.../bfd/plugin.c:134: undefined reference to `dlsym'
.../bfd/plugin.c:130: undefined reference to `dlerror'


So - what you need to do is to prevent the plugin target from being included in an all-targets toolchain, unless --enable-plugin has been specified as well.

Cheers
  Nick
