I just finished the following patch:
- When building shared and statically linked libraries, ECL creates an
extra function that performs two tasks: initializing ECL if it wasn't
done
before, and initializing the library. This can be used to create
standalone
libraries to be linked with other programs. The name of the function
typically
begins with main_dll or main_lib but it is output by ECL on screen.
An example is shown below. It has been uploaded to CVS/git but it might not
be functioning perfectly because of other issues -- namely the thing with
compiled data mentioned on a separate thread, which is still under testing.
Feel free to report problems. Best,
Juanjo

In this case
main_dll_FOO(int argc, char **argv);
is the initialization routine of the library. Note that this calls cl_boot()
but _you_ should manually insert a call to cl_shutdown() somewhere in your
program.
