To get to the point quicker, skip over the "Background:" down to "My question / problem:"
Background: I'm not really a C or C++ programmer, but I've been working on a program (well, an addition to an existing program--a lexer for Scintilla for the Foswiki/ TWiki markup language) and "limping along" well enough but very slowly. Yesterday, my build started failing with messages like this: "Package gtk+-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `gtk+-2.0.pc' to the PKG_CONFIG_PATH environment variable No package 'gtk+-2.0' found make: Nothing to be done for `all'." It took me a while to realize what must have happened, and then I think I confirmed it. Earlier that day, I had installed a new version of Adobe/Shockwave flash by using: "aptitude install flashplugin-nonfree" (Aside: It took me a while to get that to work, I finally had to find the new libflashplayer.so (in a /root directory) and copy it to /usr/lib/adobe-flashplugin/libflashplayer.so, and then restart iceweasel. (I'm not sure why it got installed to /root--probably some mistake I made--maybe having Iceweasel running while I tried the aptitude install, or maybe it was at some other point I made a mistake.) Anyway, I then remembered that during the aptitude install of flashplugin-nonfree, it deleted and replaced a lot of packages, among them: "Preparing to replace libgtk2.0-0 2.12.12-1~lenny1 (using .../libgtk2.0-0_2.18.6-1~bpo50+1_i386.deb) ..." I think that is the root of my problem, and, iirc, the version of Scintilla that I'm currently developing in cannot use gtk2.0-0_2.18. There is work going on to change that, but I'd like to finish my development work on the older version of Scintilla before contending with an upgrade. My question / problem: So, I think what I have to do is "downgrade" /libgtk2.0-0_2.18.6-1~bpo50+1_i386.deb back to libgtk2.0-0 2.12.12-1~lenny. I'll be reading man pages and googling, but I'd like to do that with a minimum of learning (i.e., with a minimum of mistakes), so I'm seeking advice. I guess there is a slight chance that all I have to do is, as one of the make messages says: "Perhaps you should add the directory containing `gtk+-2.0.pc' to the PKG_CONFIG_PATH environment variable" I.e., find the PKG_CONFIG_PATH and point it to the directory containing the new /libgtk2.0-0_2.18.6-1~bpo50+1_i386.deb instead of the old libgtk2.0-0 2.12.12-1~lenny (but, I would have thought they'd both be on the same path). Let me look into that a little bit before sending this email... Ok, I'm back. I hoped/thought that aptitude (or apt-get) had something a "what provides" command which would tell me what package I need to install for `gtk+-2.0.pc', but maybe I'm remembering that from my Mandriva days. I tried "aptitude install gtk+-2.0.pc" but that tells me: "Couldn't find any package whose name or description matched "gtk+-2.0.pc"" So, I'll send this and keep digging.
