The librsync code uses some C99 constructs, but old compilers such
|
|||
|
|
as gcc 4.7 don't default to -std=c99. This commit makes sure librsync
|
|||
|
|
is built with -std=gnu99.
|
|||
|
|
|
|||
|
|
Fixes:
|
|||
|
|
|
|||
|
|
src/rabinkarp.h:82:5: error: ‘for’ loop initial declarations are only allowed in C99 or C11 mode
|
|||
|
|
for (size_t i = len; i; i--) {
|
|||
|
|
^
|
|||
|
|
src/rabinkarp.h:82:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 to compile your code
