A plugin compiled on windows will work on linux, and vice-versa for both AMX Mod X and normal AMX Mod (the only difference really is with memory offsets for player's private data, but most modules work around this automatically, so it's not an issue). However, this is not true for AdminMod, to my knowledge.

Also if you just upload a .sma file, there will be a "Get Plugin" selection below the "Download" section. When a user clicks "Get Plugin", the plugin will be compiled automagically with the web compiler, and sent to the user.
