Kolibri OS port for gcc 5.4
|
|
|
|
Started by Siemargl @Nov 2016
|
|
Borrowed code parts from other unzip ports
|
|
|
|
howto make:
|
|
go in unzip60 directory (below this file) and
|
|
>make -f kolibri\makefile.gcc
|
|
|
|
Contains:
|
|
version()
|
|
mapattr()
|
|
mapname()
|
|
checkdir()
|
|
close_outfile()
|
|
get_extattribs()
|
|
do_wild()
|
|
set_direc_attribs()
|
|
defer_dir_attribs()
|
|
|
|
todo
|
|
datetime restore for dirs. buf in unzip - crash when SET_DIR_ATTRIB
|
|
fixed partial
|
|
-d dir error (only in unicode). Use -ddir or -d dir/
|
|
russian filenames in arhives. Now works cp866 version, unicode need to fix @kos32.c:470 (GETPATH)
