GRX library with MINGW32
by Waldemar Schultz 14 Feb '02

14 Feb '02

Hi MinGW users, Does anyone of you use the impressive graphics library GRX ? latest prerelease version is at http://grx.gnu.de/download/grx245p1.zip The GRX package is maintained by Mariano Alvarez Fernandez. I posted this question some time ago, but I got no answer. Thanks for attention. -- 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

hi all, to compile the grx244 lib with mingw32: in src/makefile.w32 i change $(WIN32_GCC_i386_STATIC): $(MAKE) -f makefile.w32 clean * if not exist $(WIN32_i386) del $(SYSTEM_TAG_PREFIX).* echo WIN32_GCC_i386_STATIC_TARGET > $(WIN32_GCC_i386_STATIC) to $(WIN32_GCC_i386_STATIC): $(MAKE) -f makefile.w32 clean * if not exist $(WIN32_GCC_i386_STATIC) if exist $(SYSTEM_TAG_PREFIX).* del $(SYSTEM_TAG_PREFIX).* echo WIN32_GCC_i386_STATIC_TARGET > $(WIN32_GCC_i386_STATIC) it works, but please check it. willi

Announce: GRX 2.4.4
by Mariano Alvarez Fernandez 11 Jan '02

11 Jan '02

Hi, all. I'm pleased to announce GRX 2.4.4 Here is the changelog: 02/01/09 Modified the demogrx test program to center the image when a mode bigger than 640x480 is selected 02/01/09 Added an alternate linux console input driver, it handles the mouse directly openning /dev/psaux, but note only PS/2 mouses work by now. It must be activate explicitly by uncomenting the switch "USE_DIRECT_MOUSE_DRIVER=y" in "makedefs.grx" 02/01/09 The linux framebuffer video driver now set the console in graphics or text mode when necesary. Now the text cursor is not show, and the svgalib mouse input driver doesn't collide with GPM, so, surprise!, it works! 02/01/09 Small changes to improve the linux console input driver 02/01/07 More patches to the Pascal interface, by Frank Heckenbach and Maurice Lombardi 02/01/02 Go to full screen in the Win32 driver if the requested framemode dimensions are equal to the screen dimensions (setting the client start area at 0,0). 01/12/22 More patches to the Pascal interface, by Frank Heckenbach and Maurice Lombardi 01/12/22 Added an optional configure script, by Frank Heckenbach 01/12/21 The linuxfb driver now open /dev/fb0 by default. An alternative frame buffer device can be specified setting the environment variable $FRAMEBUFFER 01/12/21 pascal ega colors are now functions, by Frank Heckenbach 01/12/21 fixed some borland bgi incompatibilities, by Frank Heckenbach 01/12/21 added 'const' (C) and 'protected' (Pascal) to some function parameters, to make them a little "safer", by Frank Heckenbach 01/12/16 Added imgview.pas and colortst.pas demo programs, by Frank Heckenbach 01/12/16 Change in the pascal interface: GrAllocEgaColors, GrGetScanline, etc. return a pointer to an array of GrColor, rather than to a single GrColor, by Frank Heckenbach 01/12/16 Make installation of shared libraries optional on Linux/X11 by Frank Heckenbach 01/12/16 GrSaveContextToGrayJpeg added to the pascal interface, by Maurice Lombardi 01/11/29 better w32 keyboard handling. Now most special keys with shift, alt and control combinations works 01/11/29 added jpeg functions to grx.pas and jpgtest.pas demo, by Maurice Lombardi 01/11/29 patch to define gpc-main in grx.pas and graph.pas, by Frank Heckenbach 01/11/29 patch to remove warnings on unix in test/bgi programs, by Frank Heckenbach 01/11/16 Added new function: GrSaveContextToGrayJpeg. Now GrLoadContextFromJpeg can load grayscale jpeg files 01/11/08 jpgtest test program added. It works too without jpeg support and shows a message 01/11/08 New jpeg functions (GrSaveContextToJpeg, GrLoadContextFromJpeg, GrQueryJpeg, GrJpegSupport). Added dummy functions if there isn't jpeg support 01/11/07 Added new targets to makefiles: install-info, unisntall-info. Now install doesn't install info (readme file updated) 01/09/08 Applied additional patches to update Pascal interface, new polytest.pas demo, by Maurice Lombardi 01/09/07 Applied patches to update the Pascal interface, by Frank Heckenbach. Note, the "bgi2grx" unit was renamed to "Graph", so it will be BP compatible and more natural to Pascal programmers Download it from the GRX site: http://grx.gnu.de Enjoy, M.Alvarez

It is an omission. In fact I have made some error while producing the diff, because on my setup it is included in w32 like in others.

FullScreen in Win32
by Mariano Alvarez Fernandez 04 Jan '02

04 Jan '02

I have noticed a curious Win32 effect: when the intial window client position is set to 0,0 and the client area dimensions are set to the total screen area, you obtain a fullscreen mode. I attach a patch to the win32 driver to take advantage on this. By example, after recompiling, if I set GRX20DRV to "win32 gw 1024 gh 728 nc 16M" (my screen resolution) and next run "wintest", a full screen GRX application appears.

Better GRX linuxfb driver
by Mariano Alvarez Fernandez 26 Dec '01

26 Dec '01

Hi, attached to this mail are two modified drivers I expect somebody can test: mouse/lnxinput.c It handles /dev/psaux directly, so it works with the linuxfb driver and even with the svgalib driver (indeed it works better for me than the svgalib mouse driver). The problem: only PS/2 mouses are handled. vdrivers/vd_lnxfb.c It puts the console in graphics or text mode as required, so the text cursor disappear and the mouse driver doesn't collide with GPM. I will be happy if somebody can test: - a PS/2 Intellimouse, if the driver doesn't work with it, the tt.c test program can helps to understand the mouse protocol. - a USB mouse, the linux USB mouse driver has a PS/2 compatible device driver, so opening /dev/input/mice instead /dev/psaux in lnxinput.c must work. Problems: - sometimes at the begining the mouse works badly, exiting the program and reruning it and the problem disappear. - when exit from a grx program the text console doesn't restart well, issuing a simple "ll" command and all is ok. Greetings, M.Alvarez

Hello There I have got a problem about installing GRX. I have Turbo c / Borland c 3.1 and I was not able to install it. When i say make it give me errors. How can I modify makefile? I can not use DJGPP because my project should be unde turbo c. Please help me. Yours sincerely. Mr. Gild.

configure
by Frank Heckenbach 20 Dec '01

20 Dec '01

Hi, as I said recently, I wrote a small configure script now. It doesn't support all options in makedefs.grx yet, just the most important ones and those that I need myself. E.g., I can now do all my settings for Linux/X11 with: ./configure --enable-gpc --enable-jpeg --enable-png-z --with-fontpath (More details, of course, with ./configure --help) The script is completely optional, i.e. those who don't want to use it can configure GRX manually just like before, but those like me who don't want to edit config files by hand should not need to do this anymore. It will just create a link from the appropriate makefile.foo to Makefile (so you can invoke make without `-f makefile.foo' afterwards) and change some settings in makedefs.grx, and if Pascal support is enabled, also the `{$L}' directives in grx.pas and graph.pas. It currently supports X11, svgalib and DJGPP (only X11 really tested), but if wanted, it should be easy to add Mingw support (or more config options). (diff23 -- you must set execute permissions on configure afterwards; patch can't do this) Frank -- Frank Heckenbach, frank(a)g-n-u.de http://fjf.gnu.de/ PGP and GPG keys: http://fjf.gnu.de/plan
