Re: Question regarding InstallMgr

Okay, so I've made some progress but appear to be stalled a bit.

When instructed to install a module, the command line installmgr doesn't 
seem to call InstallMgr::refreshRemoteSource() at all, and somehow the 
call to do the install succeeds.  Yet my example below fails if I don't 
call to refresh the source.

However, if I DO call refreshRemoteSource(), I will end up downloading 
EVERY module, despite only specifying one:

int myInstallModule(const char* modname) {
     sword::InstallSource is("FTP");
     is.source = "ftp.crosswire.org";
     is.directory = "/pub/sword/raw";

     sword::SWBuf installpath = getenv("HOME");
     installpath += "/.sword/";
     sword::InstallMgr* im = new sword::InstallMgr(installpath);
     im->setUserDisclaimerConfirmed(true);

     // XXX -- the call below appears to be required
     int refresh = im->refreshRemoteSource(&is);
     if (refresh) {
         printf("Refresh call failed, error: %d\n", refresh);
         exit(0);
     }

     // XXX -- this installs EVERY module, not just what is passed as an 
argument
     return im->installModule(&swrd, 0, modname, &is);
}

Someone have an idea what I might be missing?

Thanks,
