commit 55172d69d08941ecb3bb1abd640f22abca10de47
Author: Pedro Alves <palves@redhat.com>
Date: Wed Feb 11 10:04:47 2015 +0000
Wrap BFD headers in extern "C"
These were the BFD changes needed for building a C++ GDB with
--enable-targets=all, on x86_64 Fedora 20.
For libbfd.h and libcoff.h, this does same as already done when
generating bfd.h: open extern "C" in the -in.h header, and close it
from the Makefile.
bfd/doc/ChangeLog:
2015-02-11 Pedro Alves <palves@redhat.com>
* Makefile.am (libbfd.h, libcoff.h): Close extern "C" scope.
* Makefile.in: Regenerate.
bfd/ChangeLog:
2015-02-11 Pedro Alves <palves@redhat.com>
* libbfd-in.h [__cplusplus]: Open extern "C" scope.
* libcoff-in.h [__cplusplus]: Open extern "C" scope.
* libbfd.h: Regenerate.
* libcoff.h: Regenerate.
* elf-bfd.h [__cplusplus]: Wrap in extern "C".
* mach-o.h [__cplusplus]: Wrap in extern "C".
* som.h [__cplusplus]: Wrap in extern "C".
