SCM Basics
Jason W:
There should not be a library existing only in a collection like an scm, that is needed by other apps. Rather, the opposite should normally occur, that common libs are found in an extension colleciton.
Common libs should be available in common tcz extensions, and no small extension should depend on an scm self contained package.
Lee:
I may have been overly specific in my original "provides" search. The library in question was libgmp.so and I was searching for the specific version mentioned when UBC Logo failed - libgmp.so.3.4.1 - which indeed is only "provided" by lilypond.tcz.
In checking today (in the 4.x repo - the original search may have been in the 3.x repo) I checked for -any- "libgmp.so" and found several providers: gmp.tcz, lilypond.tcz and openssl-1.0.0.tcz. I don't know what versions are provided in gmp.tcz and openssl-1.0.0.tcz.
- I suppose this sub-topic should be split out to different thread as it is not really SCM-specific.
Jason W:
On looking at the list files, lilypond-2.12.2.tcz and openssl-1.0.0.tcz do not have libgmp.so* in a standard library path, so they do not provide libgmp.so* in a way that can be used by other extensions as a shared lib.
Yeah, this thread has ventured off a bit from the original topic a while back, but by now may be difficult to split the separate parts out.

Hello
what is the advantage of having the ability to "mount" and "unmount" an scm application? (.....over regular apps that are installed with the .tcz approach?)
I know that there are 4 different ways to deal with .tcz files. (Download only. On demand etc)...
How are the "scm" applications able to be handled?...is it just one approach of installing the .scm application?
how do you "unmount" and why would you need this?
i heard it's helpful to have "self contained" .scm files because when a TCL system
gets any kind of conflicts they can be easily sorted out?
thanks
V.

When you unmount the app, you free up RAM.
