MINGW/GRX sound
by Waldemar Schultz 13 Jul '01

Is there a possibility to generate some kind of sound or beep from within a MINGW/GRX Win32 program ? Thanks for any pointers. -- Gruss Waldemar Schultz. Technische Universität München, Zentrum Mathematik M1, D 80290 München Tel: +49 (0)89 2892 8226 FAX: +49 (0)89 2892 8228

Update to Linux and X11 makefiles
by Andris Pavenis 29 May '01

29 May '01

Here is update to Linux and X11 makefiles. I used different suffixes for object files, so both Linux and X11 builds in src directory can be done without overwritting object files. Diffs are generated from files I really used so some extra .CHR files related stuff is inside Andris --- grx241/src/makefile.lnx~2 Thu Apr 26 00:33:28 2001 +++ grx241/src/makefile.lnx Tue May 29 16:53:10 2001 @@ -5,6 +5,8 @@ include ../makedefs.gnu +.SUFFIXES: .o .lo .lso .c .S + INCDIR= -I. -I./include -I../include CCOPT += -DLFB_BY_NEAR_POINTER -pipe @@ -18,10 +20,6 @@ GRX20ST = ../lib/$(GRX_LIB_SUBDIR)/libgrx20.a -ifdef SHARED -CCOPT += -fPIC -D__SHARED__ -endif - OX=.o OP= @@ -32,7 +30,7 @@ $(STD_9) $(STD_10) $(STD_11) $(STD_12) BGI_O= $(BGI_1) $(BGI_2) $(BGI_3) $(BGI_4) \ - $(BGI_5) $(BGI_6) + $(BGI_5) $(BGI_6) $(CHR_1) ADDON_O= ifdef DEBUG @@ -76,38 +74,22 @@ misc/lnxmisc.o \ vdrivers/svgalib.o -ifdef SHARED -# ------------------------ SHARED -all: $(GRX20SHna) +OBJS_SHARED = $(subst .o,.lso,$(O)) +OBJS_STATIC = $(subst .o,.lo,$(O)) -$(GRX20SHna): $(LINUX_i386_SVGALIB_SHARED) $(O) - -rm -f $(GRX20SHna) - $(CC) -shared -Wl,-soname,$(notdir $(GRX20SHli)) -o $(GRX20SHna) $(O) +all: $(GRX20SHna) $(GRX20ST) -$(O): $(LINUX_i386_SVGALIB_SHARED) - -else -# ------------------------- STATIC -all: $(GRX20ST) +$(GRX20SHna): $(OBJS_SHARED) + -rm -f $(GRX20SHna) + $(CC) -shared -Wl,-soname,$(notdir $(GRX20SHli)) -o $(GRX20SHna) $(OBJS_SHARED) -$(GRX20ST): $(LINUX_i386_SVGALIB_STATIC) $(O) +$(GRX20ST): $(OBJS_STATIC) -rm -f $(GRX20ST) - $(AR) -rv $(GRX20ST) $(O) + $(AR) -rv $(GRX20ST) $(OBJS_STATIC) $(RANLIB) $(GRX20ST) -$(O): $(LINUX_i386_SVGALIB_STATIC) -endif - -$(LINUX_i386_SVGALIB_STATIC): - if [ !

Small fix for bcc2grx
by Andris Pavenis 29 May '01

29 May '01

Here is small fix for bcc2grx: I moved explicit use of memcpy() from getfillpattern() to _gr_getfillpattern and called latest from getfillpattern(). Reason problems with gcc-3.0 dev. version. Although similar problems I met are already submitted in GCC bug database (libstdc++/2989), anyway I think we should clean up libbcc.h to avoid such problems.

Announce: ctx2png
by Mariano Alvarez Fernandez 15 May '01

15 May '01

I want to announce second version of ctx2png. Now it works decently on X11. Ctx2Png is an addon to the GRX graphics library. It loads/saves a context from/to a PNG file. PNG is a lost-less compressed graphics format. It have lots of features, like the ability to handle an alpha channel. You can read more about the PNG format in http://www.libpng.org/pub/png The routines are not very efficient yet, but they work. Download: http://www.terra.es/personal/malfer/zipfiles/ctx2png.zip

GRX for GPC: Demo files?
by Markus Gerwinski 15 May '01

15 May '01

Hi folks, are there any demo files for usage of the GRX GNU Pascal interface? Especially I need to know how to just initialize a GRX program - in X11 or - from a shell. Since the Pascal interface of grSetMode has another parameter list as the original function in C, this is a non-trivial problem. Further, I need to know how to handle keyboard events and mouse events with the GRX GPC interface. Thanks in advance for any help Markus -- http://www.gerwinski.de/~markus/

Mouse Events and Graphics Contexts
by Markus Gerwinski 09 May '01

09 May '01

Hi Folks, is there an easy way to determine the graphics context a mouse event occurred in? Thanks Markus P.S.: I'm currently writing from a temporary account which I'm not allowed to subscribe to the list. So please send the answer via "group reply" or with CC to this address.

Announce: GRX 2.4.1
by Mariano Alvarez Fernandez 04 May '01

04 May '01

Hi all: I'm pleased to announce GRX 2.4.1 Here is the changelog: 01/04/25 User's guide (info) updated, by Vicente Fuentes Gea 01/04/20 User's guide (html) updated 01/04/19 Applied partially patches to make GRX compile with MS-VC by Hartmut Schirmer 01/04/18 Added install and uninstall targets to src/makefile.dj2 and src/makefile.w32 01/04/18 Patched src/bgi/text7.c to compile Ok with GCC 3.0 by Andris Pavenis 01/04/14 New API routine: GrBitBlt1bpp, contributed by Josu Onandia Added bb1test.c test program 01/04/01 Changed compiler options from "-O6 -fomit-frame-pointer" to "-O2" only. Suggested by Andris Pavenis. 01/03/27 drawpattern and bltr2v_24 added to fdrivers/fd_win32.c 01/03/26 Fixed a bug in pnm/ctx2pnm.c, when grx == NULL the actual context must be used. Reported by Vicente Fuentes Gea 01/03/25 The dj2 version uses now "uclock" in mouse/input.h to get 1ms resolution in input code. Because "uclock" can be unsafe in W3.1 when O_REPROGRAM_TIMER is defined the old code is used. A comment has been added to makedefs.dj2 01/03/25 Changed CLOCKS_PER_SECOND by CLK_TCK for linux in mouse/input.h to get real ticks per second 01/03/24 New API routines: GrSetWindowTitle and GrSleep 01/03/22 Changed DJGPP test macro from __GO32__ to __DJGPP__ by Andris Pavenis Download: For linux/X11 users: http://www.terra.es/personal/malfer/zipfiles/grx241.tar.gz For DJGPP/Mingw users (with manifests files): http://www.terra.es/personal/malfer/zipfiles/grx241s.zip Enjoy, M.Alvarez
