Subject: Avoid breakage with gcc 5
X-Git-Tag: libgpg-error-1.19~7
X-Git-Url: http://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgpg-error.git;a=commitdiff_plain;h=c01c8f0c4f55d76b037c7f6aa44ad25ede18d38a
Avoid breakage with gcc 5
* src/Makefile.am: Add -P to the C preprocessor when building
mkerrcodes.h, to avoid a noisy intermediate pipeline.
--
With gcc 5 without this patch, we see many errors like the following:
gcc -I. -I. -o mkerrcodes ./mkerrcodes.c
In file included from ./mkerrcodes.c:26:0:
./mkerrcodes.h:9:5: error: expected expression before ‘,’ token
{ , "GPG_ERR_E2BIG" },
^
./mkerrcodes.h:10:5: error: expected expression before ‘,’ token
{ , "GPG_ERR_EACCES" },
^
This patch cleans up the generated mkerrcodes.h by making the
intermediate stage clean for all the versions of gcc i tested (4.x and
5).
