Building GRX library under Linux
by Cappellini, Tony 05 Nov '01

05 Nov '01

Hello, I'm using Red Hat 7.1 with Kernel 2.4.9. I've downloaded GRX 2.4.3, unzipped it, created the 2 environment variables as directed in the readme file. I'm trying to build the GRX library ONLY, NOT an application. After compiling make -f makefile.lnx, the compile begins and proceeds for quite some time. Some errors regarding the math library are generated- but I don't know how to fix the problem. The readme file makes no specifications as to which compiler or libraries, or version of Linux to use when compiling the GRX libraries. This gives the impression that GRX should compile cleanly on any and all distributions. The GRX user's manual contains function references only, no help for compile time problems with the library sources. However, I cannot get by these errors below... gcc -c -O2 -Wall -DGRX_DEFAULT_FONT_PATH="/home/mcatocappe/grx/grx243/grx243/fonts" -DLFB_BY_NEAR_POINTER -pipe -DGRX_DEFAULT_FONT_PATH=\""/home/mcatocappe/grx/grx243/grx243/fonts"\" -I. -I./include -I../include -I../addons/print utilprog/lfbinfo.c -o utilprog/lfbinfo.o utilprog/lfbinfo.c: In function `main': utilprog/lfbinfo.c:28: warning: implicit declaration of function `printf' gcc -o ../bin/lfbinfo utilprog/lfbinfo.o ../lib/unix/libgrx20.a strip ../bin/lfbinfo gcc -c -O2 -Wall -DGRX_DEFAULT_FONT_PATH="/home/mcatocappe/grx/grx243/grx243/fonts" -DLFB_BY_NEAR_POINTER -pipe -DGRX_DEFAULT_FONT_PATH=\""/home/mcatocappe/grx/grx243/grx243/fonts"\" -I. -I./include -I../include -I../addons/print utilprog/modetest.c -o utilprog/modetest.o utilprog/modetest.c: In function `main': utilprog/modetest.c:223: warning: implicit declaration of function `kbhit' gcc -o ../bin/modetest utilprog/modetest.o ../lib/unix/libgrx20.a -lvga /usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../libvga.a(mouse.o): In function `ms_init': /usr/src/bs/BUILD/svgalib-1.4.1/src/mouse/ms.c:395: undefined reference to `pow' /usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../libvga.a(i740.o): In function `I740CalcVCLK': /usr/src/bs/BUILD/svgalib-1.4.1/src/i740.c:381: undefined reference to `log' /usr/src/bs/BUILD/svgalib-1.4.1/src/i740.c:381: undefined reference to `log' collect2: ld returned 1 exit status make: *** [../bin/modetest] Error 1 Would someone who has some experience building these libraries please help me ? thanks Tony

Using GRX in Linux
by Cappellini, Tony 01 Nov '01

01 Nov '01

Hello I'm very new to the GRX library. One of the engineers I work with has written a DOS program, which uses the GRX library. Currently this program is compiled with DJGPP. I am trying to port the program to Linux, and need help understanding what has to be done to get a GRX-based app to compile and run under linux. According to the GRX User's guide, GRX is supported under Linux. I have svgalib installed, but I don't see any mention about compatibility with the GRX library, and the fucntion calls in svgalib are radically different. Would someone please point me to some docs on how to do this ? Thanks

Some patches for grx-2.4.3
by Frank Heckenbach 14 Oct '01

14 Oct '01

Hi. (I'm not subscribed to this list, so please CC any replies to me.) I just tried grx-2.4.3, and found a number of little things to fix and improve: When building it, there are a few warnings because of some missing external declarations in some test programs and some unused variables in colors.pas. (diff0) GRX_DEFAULT_FONT_PATH must be quoted (string in a C source file), and quoted again in the Makefile (which is eaten by the shell). (see diff1 -- this diff is only for the X11 target, and should probably be made similarly for the other ones). Alternatively, one could use preprocessor stringification in loadfont.c. I suggest there to be an `install-fonts' target in the top level Makefile, so one doesn't have to chdir and call make in a subdirectory. (diff2 -- also only for X11) The rest of this mail is referring to the Pascal interface. Since I'm one of the GPC maintainers, I'm mostly interested in that. For the libraries linked, I suggest to add a case for the Linux console (though the default under Linux should be X11) and optional cases for libpng etc. (diff3). I suggest to rename the Pascal `bgi2grx' unit to `Graph' (diff 4, then mv pascal/bgi/bgi2grx.pas pascal/bgi/graph.pas -- the further diffs assume this renaming), so it will be BP compatible and more natural to Pascal programmers. demo.pas, allmodes.pas: GPC supports Str like BP, so the special case in MyStr is not necessary. sh_funcs.pas: Pi, PChar and Random have been built into GPC for a long time, so the declarations there are not necessary anymore. Furthermore, I suggest to move the remaining two declarations (KeyPressed, ReadKey) into graph.pas (perhaps conditionalized) because they'll be needed by many programs that use that unit (which would use CRT in BP), and they're external declarations of GRX routines, anyway. Then sh_funcs.pas can be removed entirely. (diff5) In grx.pas (type GrColor) it says "MUST be 32bit". So I suggest to declare it accordingly. (diff6) The handling of Pascal strings in C code is not recommendable because the internal format is likely to change in some future GPC version. It's also completely unnecessary since GPC supports (also for a long time) automatic conversion from Pascal to C strings, so simple external declarations of the C routines will work just fine (like it's already done for some newer routines, like TIFF and JPEG routines in this unit). This removes __gr_p_initgraph, __gr_p_textheight, __gr_p_textwidth, __gr_p_outtext, __gr_p_outtextxy, __gr_p_installuserfont, __gr_p_GPCstr and the files gpc_init.c, gpc_text.c. Also, instead of StrPas, the built-in and more efficient CString2String function can be used. (diff7) The Pascal units should be installed from the Makefiles. (diff8) Some argument type declarations (GrBuildPixmap, GrImageBuild, GrImageBuildUsedAsPattern, GrBuildCursor) in Pascal are, though correct, somewhat unfortunate (since pointers and arrays are not the same in Pascal). Also, grx.pas seems to be incomplete. I'm adding some of the missing routines (including PNM and PNG routines), but didn't check what more is missing. (diff9) doc/readme.bgi says: "libbcc.h won't include GRX and pascal stuff any more; there's no Pascal support any longer, sorry". Are there any known serious problems with this Pascal interface currently, or is it just that no-one is willing to update it to future changes in GRX?

MINGW with GRX 2.4 on W9x
by Waldemar Schultz 28 Sep '01

28 Sep '01

Can anyone please tell me how you switch the scope of the console window between foreground and backgrounnd (top/bottom) of the Desktop in W9x ? The following program behaves as expected, but _mostly_ the GRX window opens behind the console window (sometimes invisible) and scope doesn't fall back to the console when closing the GRX window. Quite annoying. ______________ #include <stdio.h> #include <stdlib.h> #include <conio.h> #include <windows.h> #include <grx20.h> #include <grxkeys.h> //macro to indicate that we have a GRX graphics window #define GRX_WIN { \ GrGraphicsMode _gm=GrCurrentMode(); \ volatile int _gm_win; \ \ switch(_gm) \ { \ case GR_80_25_text: \ case GR_default_text: \ case GR_width_height_text: \ case GR_biggest_text: \ case GR_width_height_color_text: \ case GR_width_height_bpp_text: \ case GR_NC_80_25_text: \ case GR_NC_default_text: \ case GR_NC_width_height_text: \ case GR_NC_biggest_text: \ case GR_NC_width_height_color_text: \ case GR_NC_width_height_bpp_text: \ (_gm_win=0); \ break; \ default: \ (_gm_win=1); \ } \ (_gm=_gm_win); \ } #define kbhit() ((GRX_WIN)?(GrKeyPressed()):(_kbhit())) #define getch() ((GRX_WIN)?(GrKeyRead() ):(_getch())) //this allows us to use kbhit() and getch() from within //a GRX window with the keyboard events disabled. char * grx_ver(void) { static char ver[200]; static char *os[10]; static char osb[10]; char *osbp=osb; os[GRX_VERSION_TCC_8086_DOS ]="TURBO C"; os[GRX_VERSION_GCC_386_DJGPP ]="DJGPPv2"; os[GRX_VERSION_GCC_386_LINUX ]="LINUX"; os[GRX_VERSION_GENERIC_X11 ]="X11"; os[GRX_VERSION_WATCOM_DOS4GW ]="Watcom32"; os[GRX_VERSION_GCC_386_WIN32 ]="Mingw32"; sprintf(ver,"%s -- GRX Version ",os[GrGetLibrarySystem()]); sprintf(osb,"%X",GrGetLibraryVersion()); while(*osbp) { sprintf(ver+strlen(ver),"%c",*osbp); if(*(++osbp)) sprintf(ver+strlen(ver),"."); } sprintf(ver+strlen(ver)," -- GCC Version %d.%d",__GNUC__,__GNUC_MINOR__); return ver; } int GRXMain() //int argc, char **argv) { int x=100,y=200; Beep(400,500); //Console GrSetMode(GR_80_25_text); //close default GRX window printf("%s%s\n\n","Hello World\n",grx_ver()); //output to console window printf("Hit Any Key\n"); //output to console window getch(); //input from console window //reopen GRX window GrSetMode(GR_width_height_bpp_graphics,800,600,24); GrSetWindowTitle(grx_ver()); GrTextXY(x,y,"Hit any Key",GrWhite(),GrBlack()); //text output to GRX window getch(); //input from GRX window //Console GrSetMode(GR_80_25_text); //close GRX window fprintf(stdout,"%s\n","Bye World\n"); //output to console window printf("Hit Any Key\n"); //output to console window getch(); //input from console window exit(EXIT_SUCCESS); } _______ Sorry for the lengthy snippet, but somebody might like to reuse it. Any suggestions or comments were highly appreciated. Thank you. -- Gruss Waldemar Schultz.
