kraptor game has evident problems with palette of images in VirtualBox (only) and I tought compiling it would help do some experiments to figure out what the problem is. Fun fact: the author of the game (released in 2004) have made kfixpal tool, to change a bunch of pictures, so as they share a common palette. Released in 2007: https://master.dl.sourceforge.net/project/kraptor/kfixpal/0.9.9/kfixpal.0.9.9.zip?viasf=1 Like the other says, less usefull, as the world evolve toward truecolor images. I decided to start from: https://master.dl.sourceforge.net/project/kraptor/kraptor_source_code/final_apr_03_2004/kraptor_final_apr_03_2004.tar.gz?viasf=1 rather than: http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/repositories/1.3/games/kraptor.zip I have no idea yet if it was a good/bad choice. I decided to use DOSEMU2 (that work well with Ubuntu Linux... might be less well in other Linux... in Gecko Linux I had no predefined, command.com and minimal tools). And so, I created in ~/.dosemu/drive_c two main directories: djzip were I put DJGPP Zip files, that I unzip in djpaul: paul@kasparno:~/.dosemu/drive_c$ ls DEBUG.COM djpaul djzip dumb093 gpm hello2.exe hello.exe krapto M2Sys135 mydos obnc tmp VGAPAL.EXE paul@kasparno:~/.dosemu/drive_c$ ls djzip all422ar2.zip all422br2.zip bnu2351b.zip djdev205.zip gcc1030b.zip mak43b.zip So I have unzip32 from: https://www.mirrorservice.org/sites/ftp.delorie.com/pub/djgpp/current/unzip32.exe in djpaul, and I have extracted each file in djzip from djpaul: cd djpaul unzip32 \djpaul\djdev205.zip etc. And I edited /usr/share/dosemu/commands/fdppauto.bat to have: path %DOSEMUDRV%:\dosemu;C:\DJPAUL\BIN ... SET DJGPP=C:\DJPAUL\DJGPP.ENV so that I can use make as soon I launch dosemu . kraptor game use https://iweb.dl.sourceforge.net/project/dumb/dumb/0.9.3/dumb-0.9.3.zip to play music and that is not already compiled in http://www.delorie.com/pub/djgpp/current/v2tk/allegro/ So I uncompressed it and copied it in ~/.dosemu/drive_c I note that makefile "included" Makefile.rdy (so I had to edit that last one). Compilation did not finish for dumb, but it build the .h file and .lib file that I did copy to: /home/paul/.dosemu/drive_c/djpaul/lib/ and /home/paul/.dosemu/drive_c/djpaul/include/ respectively. So after that I was ready to work on raptor itself. First I had to: fix DJGPP to edit the makefile so as it does target DJGPP. Then make build it. I got an error in guiprocs.c: int xedit_proc(int msg, DIALOG *d, int c) { int ret = D_O_K; typedef int (*func_ptr)(DIALOG*); int n = d->h-text_height(font); DIALOG edit, button; SET_DIALOG(edit, d_edit_proc, d->x+n/2, d->y+n/2, d->w-n, d->h-n, d->fg, gui_white_color, 0, d->flags, d->d1, d->d2, d->dp, NULL, NULL); SET_DIALOG(button, xbutton_proc, 0, d->y+1, d->h-2, d->h-2, d->fg, gui_back_color, 0, d->flags|D_EXIT, 0, 0, "...", NULL, NULL); if(d->dp2) { button.x = d->x + d->w - button.w - 1; edit.w -= button.w; //if(font == &_default_font) button.dp = "_"; } _default_font was undefined, so I just commented it. ;-) Also there were many errors about storage class of functions not valid... this was on imbricated functions: static void a(){ static void b(){...} ... I just removed the "static" beofre b() [imbricated functions] I get a lot of warnings about deprecated functions in Allegro. Up to now I did not care... but I thought it may be link to problem with palette... don't really knows. Finally, linking give a lot of errors looking like: ld: obj/djgpp/captura.o:captura.c:(.text+0x0): multiple definition of `install_allegro'; obj/djgpp/bomba.o:bomba.c:(.text+0x0): first defined here ld: obj/djgpp/captura.o:captura.c:(.text+0x20): multiple definition of `set_window_title';
