Hi,

I tried minizip under Ubuntu16.04. I first built the libminizip using CMake, then build minizip.c using:

gcc minizip.c -g -o minizip -lminizipd -lz -lbsd

I first used
./minizip a.zip 1.txt
to create a.zip first. It worked well.

Then I used
./minizip -a a.zip 2.txt
to append 2.txt into a.zip.

But seems the "append" mode doesn't work, 1.txt disappered and there was only 2.txt in a.zip.

Did I miss something or something wrong in the minizip?

The following were the command I used:

wfgu-lnx@wfgu-lnx:~/minizip$ ./minizip a.zip 1.txt
