Subject: [PATCH 15/30] Fix compilation error due to new strlcpy function that
|
|||
|
|
glibc added

The crash-utility has its own strlcpy(), but recently the latest glibc
|
|||
|
|
has also implemented the strlcpy function, which is derived from
|
|||
|
|
OpenBSD. Eventually this caused the following compilation error:
|
|||
|
|
|
|||
|
|
# make -j8 lzo
|
|||
|
|
...
|
|||
|
|
In file included from global_data.c:18:
|
|||
|
|
defs.h:5556:8: error: conflicting types for ‘strlcpy’; have ‘size_t(char *, char *, size_t)’ {aka ‘long unsigned int(char *, char *, long unsigned int)’}
|
|||
|
|
5556 | size_t strlcpy(char *, char *, size_t);
|
|||
|
|
| ^~~~~~~

5556 | size_t strlcpy(char *, char *, size_t);
|

|

...
|
|||
|
|
|
|||
|
|
To fix the issue, let's declare the strlcpy() as a weak function and
|
|||
|
|
keep the same parameter types as the glibc function has.
