Great!

You can make some tests. For example install new lua-5.4.tcz and lua-5.4-lib.tcz aside with lua-5.3.tcz and lua-lib.tcz. Then load and install vis.tcz and see does vis editor will actually run.

It sure does :)

jazzbiker:
It was compiled against the present lua-5.3. So liblua.so.5.3.6 is accessible, everything seems to be ok. Include files are separated by original lua installer and lua-5.4.pc is ready to use. Seems like now You have the choice of lua versions, even for development.

Thanks, great!

I think the only thing to be tested is

--- Code: ---readlink /usr/local/lib/liblua.so

--- End code ---

Hi, jazzbiker.

Loading old version of the library then loading new version works as expected:


--- Code: ---$ tce-load -i lua-5.3-lib
lua-5.3-lib.tcz: OK
$ readlink /usr/local/lib/liblua.so
/tmp/tcloop/lua-5.3-lib/usr/local/lib/liblua.so
$ tce-load -i lua-5.4-lib
lua-5.4-lib.tcz: OK
$ readlink /usr/local/lib/liblua.so
/tmp/tcloop/lua-5.4-lib/usr/local/lib/liblua.so.5.4.6
--- End code ---

Then I make sure onboot.lst has no lua-*-lib extensions, and reboot.

Next test: Load new version of the library, then load the old version:


--- Code: ---$ tce-load -i lua-5.4-lib
lua-5.4-lib.tcz: OK
$ readlink /usr/local/lib/liblua.so
/tmp/tcloop/lua-5.4-lib/usr/local/lib/liblua.so.5.4.6
$ tce-load -i lua-5.3-lib
lua-5.3-lib.tcz: OK
$ readlink /usr/local/lib/liblua.so
/tmp/tcloop/lua-5.4-lib/usr/local/lib/liblua.so.5.4.6
--- End code ---

This test also gives us the result we want (liblua.so pointing to newest version), but it is somewhat unexpected. I would have expected that loading lua-5.3.lib (which does not have a startup script for smart liblua.so) would have clobbered liblua.so with its own version (i.e., the one that points to /tmp/tcloop/lua-5.3-lib/usr/local/lib/liblua.so which in turns points to /tmp/tcloop/lua-5.3-lib/usr/local/lib/liblua.so.5.3.6).
