GRX 2.4.4 pre-release
by Mariano Alvarez Fernandez 28 Nov '01

Hi. I have uploaded a pre-release of GRX 2.4.4. Download it from: http://grx.gnu.de/download/grx244p1.zip MD5SUM for the package: ee807ba1edf3c20fdff8c62fe249ca62 *grx244p1.zip Only the zip archive is provided, but note, the zip archive expand to grx244, not to the contrib directory. Changes from 2.4.3: - added the changes to the pascal interface. - new functions to load/save jpeg image files. - the info install has now his own targets: install-info, uninstall-info - added "-lm" to make grx programs in the linux console makefiles, it is not ever necesary, but it doesn't hurt. Testing and comments will be welcome.

Any reason ? GrSaveContextToJpeg is a new function, the old SaveContextToJpeg lived in the addon subdir, and I didn't know if we can change it, so I had write a new one and his pair: GrLoadContextToJpeg. Can you add it to grx.pas? SaveContextToTiff live in the addon subdir too, so I need the author permission to rename it, place it in the src/gformat subdir and apply the GRX license. Hartmut, can I do it?

MINGW 32 C-functions docs

Hi, folks, I am about to port DJGPP-C-programs that use th GRX graphics library to MINGW32. My Question is where to find detailed documentation about the C-functions available when using MINGW32. I mean something like the command 'info libc alpha findfirst' which is available on DJGPP. Thanks for any hint. -- Gruss Waldemar Schultz. schultz(a)ma.tum.de Technische Universität München, Zentrum Mathematik M1, D 80290 München Tel: +49 (0)89 2892 8226 FAX: +49 (0)89 2892 8228

Please, mail in plain text if possible (not html). I'm not was able to respond your mail directly. I'm not sure what is your problem. What font are you using?. Can you made a small piece of code to see the problem?

by Kristopher Wong 19 Nov '01

19 Nov '01

Hi, I face a big problem when I try to display chinese character in linux by using grx library. I have found a tools that I can convert a chinese ttf file to fnt file. However, I still cannot display the chinese fonts (or any multibytes languages) correctly. Can anyone teach me what is the step to display the chinese fonts? Here is the host configuration in my host: 1. RedHat Linux 7.0 with CLE. 2. GRX version 2.4.3. Thanks for your help! Best regards, Kris Wong

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
