Re: [e-users] error on statically linked programs that use imlib2 static libraries

2023-07-26 Thread ruivlea via enlightenment-users 
this make things clear. thankyou. so, shared only.
i tried build it static because in configure --help there is:
--enable-shared[=PKGS]  build shared libraries [default=yes]
--enable-static[=PKGS]  build static libraries [default=yes]

You can't do this due to the way imlib2 was designed to work with loader
modules. So shared lib linking only. Evas is similar but actually can be built
in a way to inline loaders too and then allow for functional static linking.
Evas is what replaced Imlib2.

Re: [e-users] error on statically linked programs that use imlib2 static libraries

2023-07-26 Thread Kim Woelders 
As is, things will not work when using -static. The loaders are loaded 
dynamically as separate shared objects.


One reason to do this is to avoid loading all libraries used by all 
loaders (libpng, librsvg2, etc., and their dependencies) at application 
startup but defer it until needed.
Another is to isolate applications using imlib2 from the licencing of 
the libraries used by the loaders.
