I've applied this with a couple of little tweaks, thanks. I've also
noticed a couple of small memory leaks in your program. A memory leak
happens when you allocate some memory, but do not free it (usually using
You can test your program doing:
yum install valgrind (as root)
valgrind --leak-check=full ./.libs/lt-pkgenpack --verbose hal-info.pack hal-info
This will give you output at the end like this:
==25990== 10 bytes in 1 blocks are definitely lost in loss record 1 of 12

You don't need to worry about the "possibly lost" output below these two.
In this case you are leaking 74 bytes of memory. In the first you're
using g_strconcat() in main() without freeing the result, and in the
second you are using g_build_filename() in pk_generate_pack_scan_dir().
Could you fix up these leaks and submit a patch please? Thanks.
