I just make a script to check dependencies
It check all dependencies in a directory, that should come in handy when you're compiling
At the same time, it shows which libraries are absent
The result goes to standard output when the absent one goes to standard error
There're 4 different types of output
With option -f, you'll get a full list of sorted dependencies
with option -l, you'll get a long version of tcz list
with option -s, you'll get a short version of tcz list (similar to chkonboot.sh)
with option -n, you'll get a list of libraries that were not found (it goes to standard error)
The idea is quite simple
1. find all files and run ldd to check all dependencies
2. generate a full list
3. remove the files that are under the directory from the full list
4. generate a "NOTFOUND" list
5. generate a full tcz list
6. remove all redundant
Usage: get-dep-list [-option] your_top_directory
Available Options (Default -ns)
-f show full dependencies list
-h show help
-l show detected tczs (long)
-n show dependencies that are not found
-s show detected tczs (short)
Tested on 7.2 x86
Boot base norestore
tce-load only alsa
As you can see, the libsamplerate.so.0 is missing
After loading the libsamplerate.tcz extension fix the problem
By the way ~
Please add as a dependency, thanks.
However, the KERNEL module were not listed, extensions like these should be handled with care

I've found many extensions either having missing dependencies or loading too much extensions
I'm afraid I can't list them all, but I hope this script would help
