Aborting compilation
by Pascal Viandier 30 Apr '09

30 Apr '09

Hi all, Is there a gpc directive that can issue a message and then abort the compilation? I tried {$M ...} but it does not stop the compilation process. My goal is to prohibit the use of FillChar() in our code by stopping the compilation when the compiler finds one. I used a macro that redefines FillChar(a,b,c); as {$M ERROR: Fillchar use is not allowed!} but this does not seem sufficient to prevent its usage and its destructive effect on strings :-( If there is no such compiler directive, any other suggestion is welcome. Regards Pascal Viandier

Wasn't aware that someone had GPC working with the GCC 4 back end, but I'm happy to hear it (must not have been paying enough attention to the list). Anyway, I now have a working GPC on my laptop and I have verified that my existing GCC (4.2.3) still works. Thanks to both you and the Chief for your help. --------------------------| John L.

Stupid Installation Question
by John L. Ries 19 Apr '09

19 Apr '09

How does one go about compiling and installing GPC under Linux in such a way as to not interfere with the GCC 4 one already has? I've ended up installing and ripping out GPC on the Linux side on three different occasions (always Slackware) because I was no longer able to use GCC 4 (as much as I hate C, it is useful to have a C compiler around for compiling free software). Seems that the GCC 3 libraries GPC needs end up pre-empting the GCC 4 libraries. If people need exact error messages, I can go ahead and redo the install, so I can remember what they are (it's been a while). I did recently install that other free Pascal compiler, only to discover that it wouldn't compile my nearly completed project from 5 years ago (not even my Borland-style units), so I really would like to have GPC back on my Linux boxes without the hassle of changing distros. BTW: As much as I appreciate Kevan Hashemi's making a pre-compiled Linux GPC binary available, my preference would be for a 64-bit build. --------------------------| John L.

Stupid Installation Question # 2
by John L. Ries 19 Apr '09

Probably related to the first. I notice that Gentoo masks its GPC e-build. Are there any precautions to be observed when unmasking it so it can be installed? --------------------------| John L. Ries | Salford Systems | Phone: (619)543-8880 x107 | or (435)867-8885 | --------------------------|

I was referring to "Where on earth do I get a non-broken version of sed? What is sed anyway? Why won't patch work on this machine with these diff files? Is it patch that's not working or is it just that I'm a retard? What does it mean that the .tar.bz.tar archive is in an unrecognizable format?" Compiling GPC will be four hours work for me, minimum. > If you find one, it may not work. So far, that 20041218 distribution of binaries has worked on every single one of the two dozen machines we have loaded it onto. Why would the 20070904 distribution fail to work?

Hello, I am trying to compile an old pascal code with gpc. There was a problem with the autolinker, symbols collided between ncurses and grx (I think) ,so I removed it and build a command line manually in a makefile. I turned off the graphics and everything worked fine, it compiled linked and produced the desired output. Now I am trying to turn the graphics on again. The problem is that the linker complains that the following symbols could not be found. __gr_setcolor' `setlinestyle' `outtextxy' `setwritemode' `setviewport' `clearviewport' `__gr_getfillsettings' `setfillstyle' `settextstyle' `__gr_closegraph' So I edited the graph unit and replaced the references to these symbols by impleamantations that do nothing. No everything compiles again, a graphics window appears, but nothing is drawn into it. Here is my compile and link command line: c:\dev_gpc\bin\gpc c:\dev_gpc\examples\gbr\brichten.pas -oc:\dev_gpc\examples\gbr\richt.exe -lgrx20 c:\dev_gpc\units/graph.o -lgrx20 -lgdi32 c:\dev_gpc\units/dos.o c:\dev_gpc\units/grx.o c:\dev_gpc\units/gpc.o c:\dev_gpc\units/system.o c:\dev_gpc\units/mathe.o c:\dev_gpc\units/crt.o c:\dev_gpc\units/crtc.o -lpanel -lpdcurses c:\dev_gpc\units/math_nst.o c:\dev_gpc\units/br_var1.o c:\dev_gpc\units/br_var2.o c:\dev_gpc\units/br_proz.o c:\dev_gpc\units/br_plan.o c:\dev_gpc\units/geometri.o c:\dev_gpc\units/br_bili.o c:\dev_gpc\units/br_dio.o c:\dev_gpc\units/br_ko_g.o c:\dev_gpc\units/grafikpl.o -fno-inline -s -fno-io-checking -fno-range-checking -fimplicit-result -O1 -Wno-warnings -fno-assertions -fextended-syntax -fignore-function-results -fcstrings-as-strings -fpointer-arithmetic -march=i486 --no-autolink --no-automake -funit-path=c:\dev_gpc\units;c:\dev_gpc\examples\GBR\UNIT -funit-destination-path=c:\dev_gpc\units -Bc:\dev_gpc\lib\ -Bc:\dev_gpc\lib\gcc\mingw32\3.4.5\ -funit-path=C:\dev_gpc\examples\GBR\INC;C:\dev_gpc\examples\GBR\UNIT --no-autolink -LC:\dev_gpc\lib Note that -lgrx20 is given and that -no-autolink is given. I also analyed libgrx20.a with nm. It told me that a symbol. `_setlinestyle' does existis. But replacing `setlinestyle' with `_setlinestyle' in the graph library caused the linker to complain that the symbol `_setlinestyle' was not resolved. So my basic question is how can I turn on the graphics. Yours Dirk

I did not know that the order of the command line arguments is important now everything works fine
