Trouble is, the plugin path is hardcoded (and absolute!):
plugin.cpp: OBPlugin::LoadAllPlugins:
------------------------------------------------
...
DLHandler::getConvDirectory(TargetDir); // < This fetches the path
vector<string> files;
if(!DLHandler::findFiles(files,DLHandler::getFormatFilePattern(),TargetDir)) {
return;
}
...
dlhandler_unix.cpp:
------------------------------------------------
bool DLHandler::getConvDirectory(string& convPath)
{
string testPath;
testPath += OB_MODULE_PATH; // defined in src/config.h.cmake -> babelconfig.h
convPath = testPath;
return true;
}
babelconfig.h:
------------------------------------------------
#define OB_MODULE_PATH "/usr/lib/openbabel/2.3.90"
So it doesn't look like this can be adjusted via an env var.
