This commit backports an upstream patch made for gnupg2 into gnupg, in order to fix build failures with gcc 10 due to the use of -fno-common. Due to the code differences between upstream gnupg2 and the old gnupg 1.x, the backport is in fact more a rewrite than an actual backport.

Subject: [PATCH] build: Always use EXTERN_UNLESS_MAIN_MODULE pattern
|
|
|
|
This patch is loosely based on upstream commit
|
|
6aff8a132815a84bab69401c1e7de96ec549fbf2 ("build: Always use
|
|
EXTERN_UNLESS_MAIN_MODULE pattern."). However, this upstream commit
|
|
applies to gnupg2, and the code base has changed quite significantly
|
|
compared to gnupg 1.x, so upstream's patch cannot be applied
|
|
as-is. The goal of the patch is to make sure each variable is only
|
|
defined once, ass gcc 10 now default to -fno-common.
|
|
|
|
Essentially, this patch mainly fixes the EXTERN_UNLESS_MAIN_MODULE
|
|
define so that it really expands to "extern" when
|
|
INCLUDED_BY_MAIN_MODULE is not defined, even on non-RiscOS
|
|
systems. Contrary to upstream's patch we however do not factorize the
|
|
multiple EXTERN_UNLESS_MAIN_MODULE definitions into a single place as
|
|
it requires too many changes: instead we simply fix the few
|
|
definitions of this macro.
|
|
|
|
Once the macro is fixed, two places need to define
|
|
INCLUDED_BY_MAIN_MODULE: tools/bftest.c and tools/mpicalc.c so that
|
|
when they include the common headers, their variables are at least
|
|
defined once.
|
|
|
|
The iobuf.{c,h} case is handled differently: iobuf.h gains an
|
|
unconditional "extern", with the variable being added to iobuf.c. This
|
|
is identical to what upstream's
|
|
6aff8a132815a84bab69401c1e7de96ec549fbf2 is doing.
