 I'm a rising senior at Swarthmore College working as Pidgin's resident "Maintenance Hero" through the [[SummerOfCode2015|2015 Google Summer of Code]]. My main goal is to help get our 3.0.0 release out the door. I also plan to work on [[vv|voice and video]] and end-to-end encryption.

+Pidgin 3.0 has many dependencies, including some new ones and some that are a little tricky to get set up properly. Don't take this as gospel - it's simply what I've done to make the builds work reliably.
+
+I've been doing my dev work on Ubuntu 15.04 (the most recent release at the moment). I install all manually compiled packages into the prefix `$HOME/env/` to keep `/usr/` clean and Ubuntu-specific. I strongly recommend this - it makes it easier to specify which version of a library should be used, and it prevents linker-related headaches and system reinstalls when you start getting library-related errors. I've added `$HOME/env/` to the following environment variables to make it fully usable:
+
+* `PATH`
+* `LIBDIR`
+* `LIBRARY_PATH`
+* `LD_LIBRARY_PATH`
+* `C_INCLUDE_PATH`
+* `CPLUS_INCLUDE_PATH`
+* `PKG_CONFIG_PATH`
+
+=== GPlugin ===
+
+[https://www.guifications.org/ GPlugin] was added as a Pidgin dependency in May 2015. It's meant to allow plugins to be written in any programming language through the use of [https://wiki.gnome.org/Projects/GObjectIntrospection GObject introspection]. There were build problems in 0.18 involving Mozilla's gjs library (apparently only C++ headers were available while C headers were needed), but that's been removed as a dependency for now.
+
+GPlugin is new, and isn't yet included in Debian or Ubuntu's package repos. You therefore have to build from source. Additionally, I wasn't able to find which (if any) environment variable determines the search path for `.gir` files. I therefore grudgingly installed it without my build environment prefix. I've since been told that such an environment variable does exist, though - I'll share it here once I find it.
