| 01:24 | <@McMartin> | Argh dammit |
| 01:24 | | * McMartin beats libsdl.org with a cheese |
| 01:24 | | * McMartin then sets about copying all his code over to his Mac. |
| 01:24 | <@McMartin> | Why are there no prebuilt MinGW SDL_image builds? |
| 01:32 | < gnolam> | Shit like that is part of the reason I did away with MinGW altogether. :P |
| 01:34 | < gnolam> | Way too many libraries giving you the choice between pre-built MSVC binary, MSVC project file, or - for MinGW - some kind of arcane build system straight from the screaming pages of the Kitab al-Azif itself that has about a 1 in 10 chance of actually working, even once you've fulfilled the dependencies and pawned your soul. |
| 01:36 | < gnolam> | Oh, and getting all the dependencies to work will probably require a virgin, a lunar eclipse and a blood sacrifice. |
| 01:37 | <@ToxicFrog> | Alternately, you can use the mingw tools to link against the msvc binaries. |
| 01:37 | <@McMartin> | TF: That is what just failed. |
| 01:37 | <@McMartin> | It's possible this is Code::Blocks being retarded. |
| 01:37 | <@ToxicFrog> | I've never used c::b, so no idea on that front. |
| 01:38 | | * McMartin is working on a program that will convert UQM-style fonts into something GM8 can use. |
| 01:38 | <@ToxicFrog> | If you were trying to link against sdl_image.dll directly, try linking against the import library instead, and vice versa. |
| 01:38 | <@McMartin> | I'd just loot Iji's font code but I want to add kerning. |

| 02:05 | < celticminstrel> | C::B on Mac is kinda unstable. At least, it was when I last checked, which was a month or three ago. |
| 02:06 | < celticminstrel> | I'm failing to determine whether you're talking about it on Mac or Windows... :| |
| 02:06 | < celticminstrel> | Actually, never mind, it looks like Windows. |

| 02:08 | <@ToxicFrog> | celticminstrel: mingw is a windows thing, soooo... |
| 02:09 | < celticminstrel> | Just missed the connection at first between MinGW and Code::Blocks. |
| 02:26 | <@McMartin> | I was using C::B on WIndows |
| 02:27 | <@McMartin> | I'm taking my code and finishing it in Xcode because it isn't, itself, a "deliverable". At least not yet. |
| 02:36 | <@McMartin> | Yeah, OK, screw Xcode |
| 02:36 | | * McMartin adds four tokens to his source code and it compiles fine with a commandline g++ |
| 02:39 | < celticminstrel> | What was Xcode doing? |
| 02:39 | < celticminstrel> | And what four tokens? |
| 02:39 | < celticminstrel> | Sorry, just curious. |
| 02:40 | <@McMartin> | Xcode wasn't doing anything, it's just totally unnecessary |
| 02:40 | <@McMartin> | I had to modify some #includes to work right with Mac g++'s -framework argument, and then I had to #undef main because I'm abusing SDL in a way Cocoa doesn't like. |
| 02:41 | < Vornicus-Latens> | Yeah, you don't need xcode to build on mac. the old mac build of ottd was a work of art. |
| 02:41 | <@McMartin> | (Normally SDL on Mac requires a Cocoa shim layer Xcode will automatically add for you. Since I'm using SDL as basically an ImageMagick API, I don't need it for this). |
| 02:41 | <@McMartin> | There are a lot of things Xcode makes a whole lot easier, though. |
| 02:41 | <@McMartin> | This is a CLI app that makes extensive use of GUI libraries, and so that's Kind Of Weird. |
| 02:42 | | Vornicus-Latens is now known as Vornicus |
| 02:43 | <@McMartin> | (Basically, I have to include "SDL/SDL.h" instead of "SDL.h") |
| 02:43 | < celticminstrel> | I think you need that Cocoa layer to get an SDL window, or something... if you're not using the drawing aspect of SDL, you wouldn't need the Cocoa layer... right? |
| 02:43 | <@McMartin> | celticminstrel: Right, but the way SDL mutates the entry point is by #defining main to a different value |
| 02:43 | <@McMartin> | So I had to #undef main in *my* source because I want *that* to be my entry point, thankyouverymuch. |
| 02:44 | < celticminstrel> | Oh yeah, Xcode has this annoying habit of not finding includes if you give a relative path rather than just the include filename... :| |
| 02:44 | <@McMartin> | This isn't Xcode's fault |
| 02:44 | <@McMartin> | This is "I'm too lazy to actually type out all the -I and -L stuff when I could just do -framework SDL on the cmdline" |
| 02:44 | <@McMartin> | But -framework stuff needs the framework identifier in the #include. |
| 02:48 | | * McMartin re-teaches himself how to use C++ iostreams. |
| 02:52 | <@McMartin> | There we go. |
| 02:53 | | kwsn [kwsn@Nightstar-7426b23f.dyn.centurytel.net] has joined #code |
| 02:54 | < Vornicus> | Answer: avoid them like the plague. |
| 02:56 | <@McMartin> | Too lazy to do the checking required to make snprintf safe and functional. |
| 02:57 | <@McMartin> | Also, hm |
| 02:58 | <@McMartin> | I didn't think this cunning plan through all the way |
| 02:58 | <@McMartin> | It may be necessary to apply TW's library to this. |
| 03:01 | | gnolam [lenin@Nightstar-38637aa0.priv.bahnhof.se] has quit [[NS] Quit: Z?] |
| 03:05 | < celticminstrel> | I quite like the iostreams actually. |
| 03:05 | < Vornicus> | You've never had to do formatting with them, then. |
| 03:06 | < celticminstrel> | Though they have been known to fail with cryptic error messages for completely non-apparent reasons. |
| 03:06 | < celticminstrel> | And by "fail", I mean at runtime. |
| 03:06 | < Vornicus> | It's so coated in modeyness that it's not funny. |
| 03:06 | <@McMartin> | Well, that's what I needed to do here, though it was a simple << setfill('0') << setw(width) |
| 03:07 | < celticminstrel> | The <iomanip> stuff is nice but a bit verbose for my liking. |
| 03:08 | < celticminstrel> | I actually do like the conciseness of printf; if there were a type-safe version of that, I might actually consider using it for string formatting (actually, there is a non-standard one, but I'd rather have one that can also support custom types). |
| 03:08 | <@McMartin> | Here it's more raging at the necessity for string processing in C. |
| 03:09 | < celticminstrel> | I'm thinking a function where you do something like sprintf("format string", var1, var2, var3) and it returns a std::string with the result. |
| 03:09 | <@McMartin> | ostringstream tends to be worth the pain. |
| 03:09 | <@McMartin> | Right |
| 03:09 | < celticminstrel> | That would be really nice. |
| 03:09 | <@McMartin> | The usual way to do that is to have a function that wraps two calls to snprintf and a call to std::string's constructor. |
| 03:11 | | * McMartin is about to win, but realizes that he has failed due to BMP's lack of alpha channels. |
| 03:12 | < celticminstrel> | I'd probably wrap the nonstandard function instead. I think it's asnprintf or something like that. |
| 03:12 | < celticminstrel> | But yeah, not that hard to make said function. |
| 03:13 | < celticminstrel> | Nevertheless, a function like that which could also handle class types would be nice to have. |
| 03:15 | < celticminstrel> | And that is not so easy. It'd probably require variadic templates. |
| 03:36 | | Tarinaky [Tarinaky@Nightstar-f349ca6d.plus.com] has quit [Connection closed] |
| 03:41 | <@McMartin> | OK, that's a start |
| 03:42 | < celticminstrel> | I'm going to assume that has no relation whatsoever with my most recent line. |
| 03:42 | <@McMartin> | Quite. |
| 03:43 | <@McMartin> | I now need image editors I don't have on this system |
| 03:45 | <@McMartin> | Basically, I've gotten my font stored as a BMP |
| 03:45 | <@McMartin> | Now I need to either link in TW's SDL_imagesave code or process the image so that it has a proper alpha channel. |
| 03:45 | < celticminstrel> | If Mac: Preview. |
| 03:46 | <@McMartin> | I saw "instant alpha" but it didn't give me proper colorkeying. |
| 03:48 | <@McMartin> | The problem here is not "this isn't a PNG", it's "because it's going through BMP alpha channels are being wiped" |

| 03:49 | < celticminstrel> | Can't you convert it to PNG and it'll work? :| |
| 03:49 | <@McMartin> | Er |
| 03:49 | <@McMartin> | Yes, but |
| 03:49 | <@McMartin> | It's then an alpha-free PNG |
| 03:49 | <@McMartin> | Because BMP doesn't have alpha. |
| 03:50 | < celticminstrel> | Oh, and you need it to have alpha? |
| 03:50 | <@McMartin> | Yes, that is the whole problem, as I said |
| 03:50 | < celticminstrel> | Ah. |
| 03:51 | <@McMartin> | Basically, the goal here is "given 95 PNGs that specify a sprite-font, produce 1 PNG and one metadata file that lets you represent the same thing more compactly, and also in a form that pre-existing game engines will like" |
| 04:32 | | Kindamoody is now known as Kindamoody[zZz] |
| 04:47 | <@McMartin> | Yeah, TW's stuff works |
| 04:47 | <@McMartin> | Also, my earlier problems on Windows were in fact c::b's fault, not SDL's |
| 05:07 | <@McMartin> | So now I have a usable PNG |
| 05:07 | <@McMartin> | Now I just need to dump the kerning info in a usable form. |
