Hello Rich

I was not suggesting any attachment just an update

I was able to compile but making it persistent was a big problem.
Finally installed in a custom folder and using LD_LIBRARY_PQTH

Thank yoi for your help.

No problem. The statement was a little vague so your intent was not clear to me.

Looking here:
https://github.com/mchehab/zbar/blob/master/INSTALL.md
I saw the following:

Quote

You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give configure the option --exec-prefix=PATH, the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix.

So if you include this when you run  configure:

Code: [Select]

--exec-prefix=/home/tc/packageThen  make  should install libraries and programs under  /home/tc/package.

If you install  squashfs-tools.tcz  you can now create an extension from the installed files like this:

Code: [Select]

cd
mksquashfs package libzbar.tcz -noappend
