Subject: [PATCH] tools: Add error.h for non-glibc case
|
||||
|
||||
error is glibc specific API, so this patch will mostly not accepted
|
||||
upstream given that elfutils has been closely tied to glibc
|
||||
|
||||
This is a OE specific workaround for musl.

Subject: [PATCH 2/2] sepdebugcrcfix.c: do not use 64bit variants
|
||||
|
||||
configure.ac checks for largefile support via AC_SYS_LARGEFILE
|
||||
already, therefore use off_t, open and lseek instead of 64bit
|
||||
variants. Musl e.g. does not define them without _LARGEFILE64_SOURCE
|
||||
and error is not seen on glibc because _GNU_SOURCE defines
|
||||
_LARGEFILE64_SOURCE.
|
||||
|
||||
This patch is marked as inappropriate as debugedit obviously only
|
||||
wants to support glibc or some glibc compatible libcs. We can see
|
||||
this from the error() usage. And this patch is only for musl.

Subject: [PATCH 3/3] Makefile.am: do not update manual
|
||||
|
||||
The tarball ships these manuals, no need to re-generate them.
|
||||
We have local patches for debugedit.c and sepdebugcrcfix.c,
|
||||
this will triger re-generation of the manuals, which causes
|
||||
error of missing help2man.
|
||||
|
||||
This is an OE specific patch. If we don't have local patches
|
||||
patching debugedit.c and sepdebugcrcfix.c, this patch is also
|
||||
not needed.
