Subject: [PATCH] common.h: replace getline() with fgets
|
|
There is an unofficial upstream patch adding a simple getline()
|
to libmissing.h. Unfortunately the patch creates issues if the
|
toolchain is using glibc (autotools cache?) so for the moment
|
keep the old hack and wait for commits upstream.
|
|
Fix:
|
|
| ubi-utils/ubiformat.o: In function `prompt.constprop.4':
|
| ubiformat.c:(.text+0x70): undefined reference to `getline'
|
|
Upstream-Status: Inappropriate [klibc specific]
