Dear Gale, I will be out of town and away from the Intel Mac for a week or so. I will come back by October 17, and then I will check the things you are asking for. Sorry for the delay and thank you very much for your concern.

type mismatch in argument 2 of `NumToString'
by Ken G. Brown 08 Oct '06

08 Oct '06

Thx a lot for your long explanation of Strings. Here is another one that has me baffled. My code in a procedure: procedure doHeader (pageNum, numPages : Integer); var pageNumStr, numPagesStr : Str255; the call: NumToString(pageNum,pageNumStr); I get compile error: error: type mismatch in argument 2 of `NumToString' In NumberFormatting.p procedure NumToString(theNum: SInt32; var theString: Str255); external name '_NumToString'; What do I need to do in this case? Thx Ken

Why Syntax error in function declaration?
by Ken G. Brown 07 Oct '06

07 Oct '06

Mac OS X 10.4.8, gpc 35u2 This is driving me crazy. Why does this snippet give a compile error in the function declaration? error: syntax error before `(' program PrtTst2; uses GPCStringsAll; // from the gpc.pdf manual this is the way a function should look // // function function_identifier (parameter list): result type ; // declaration part // begin // statement part // end; function fixDateYear(thisDate : String(255)) : String(255); begin end; begin {main} end. Thx for any help, Ken

indirect jmp
by Nestor Aguilera 06 Oct '06

06 Oct '06

Hi, I am running Mac OS X 10.4.8 on a MacBook Intel 2Ghz Core Duo, using gpc installed from gpc345u2-intel.dmg (downloaded from http:// www.microbizz.nl/gpc.html) When compiling I get errors involving "indirect jmp without `*'" as in $ gpc helloworld.p /var/tmp//ccz2cAa1.s:110:indirect jmp without `*' /var/tmp//ccz2cAa1.s:127:indirect jmp without `*' /var/tmp//ccz2cAa1.s:144:indirect jmp without `*' /var/tmp//ccz2cAa1.s:161:indirect jmp without `*' /var/tmp//ccz2cAa1.s:178:indirect jmp without `*' /var/tmp//ccz2cAa1.s:195:indirect jmp without `*' /var/tmp//ccz2cAa1.s:212:indirect jmp without `*' where helloworld.p is program helloworld(input, output); begin writeln('Hello world') end. Do you know what the problem is? Thanks, Nestor Aguilera

Serial Out Example?
by Ken G. Brown 04 Oct '06

04 Oct '06

I need to support a legacy custom printer driver app in Pascal which used to directly access the old style serial ports on Mac OS 9. I need to get it running from OS X since it is used for point of sale invoice printing. The computers have been upgraded. I have the Keyspan USA28x USB to 8 pin mini din adapter, and have their test program working but now I need to either call their C routines somehow, or rewrite something similar in Pascal. I also have most of the legacy Pascal code compiling, except for the serial stuff. Can anyone point me to appropriate examples on how to do serial drive using Xcode and gpc? Thx for any pointers. Ken

gpc20060325 says "new style GCC `-H' output detected" and doesn't want to build
by Igor Marnat 03 Oct '06

03 Oct '06

Hello List! I've built two toolchains (native for i386-linux and cross for ppc-linux target) based on gpc 20060325 and gcc 4.0.3. I have the units that use {$L file.c} directive. Native compiler build them just fine but cross compiler of the same version gives an error "new style GCC `-H' output detected" and stops build. I couldn't find any information in Google and GPC mailing lists. Please, any ideas? Native compiler version: [igor@marnat2 main_program]$ gpc -v Using built-in specs. Configured with: ../gcc-4.0.3/configure --enable-languages=c,pascal --enable-threads=posix --prefix=/home/igor/src-big/tools Thread model: posix gpc version 20060325, based on gcc-4.0.3 Cross compiler version: [igor@marnat2 main_program]$ ppc-linux-gpc -v Using built-in specs. Configured with: ../configure --prefix=/home/igor/src-big/ELDK4.0/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --disable-libgcj --target=ppc-linux --with-newlib --enable-languages=c,pascal --enable-multilib=no --disable-multilib Thread model: posix gpc version 20060325, based on gcc-4.0.3 (DENX ELDK custom version 4.0.3-1) Best regards, Igor Marnat mailto:marny@rambler.ru

packed array size
by Jonas Maebe 03 Oct '06

03 Oct '06

Hello, What is the size of this packed array in gpc on 64 bit systems: type ta = 0..$7fffffff; tb = packed array[0..799] of ta; Is it 3100 or 3104 bytes? On a related note, can someone explain me how to build gpc for Mac OS X/ppc64? powerpc64-apple-darwin8 doesn't seem to be a supported target, but maybe it's called differently? Thanks, Jonas

import gpc
by Bastiaan Veelo 26 Sep '06

26 Sep '06

Hi there, Is it correct that gpc does not look in its own units directory by default? If I have a main.pas that does import gpc, I have to build with something like (on windows): @gpc --print-file-name=units > temp.tmp @SET /p GPC_UNITS=<temp.tmp DEL temp.tmp gpc --unit-path="%GPC_UNITS%" --automake main.pas Can this not be done more straightforward? gpc.exe 20051116, based on gcc-3.2.3 (mingw special 20030504-1) Best regards, Bastiaan.

Strange up-to-date check failure.
by Bastiaan Veelo 26 Sep '06

26 Sep '06

Hi, I finally reproduced an unjust "`somfile.gpi' must be recompiled" message with a minimal example. This is the tree: \ywin.pas \testy.pas \contrib\gpc.o \contrib\gpc.gpi gpc.* are compiled from gps.pas as supplied with the compiler. ywin.pas and testy.pas are as follows ============== ywin.pas START =================== MODULE ywin; EXPORT ywin = (dummy); IMPORT gpc only (PCStrings, CParamCount, CParameters); procedure dummy; end; procedure dummy; begin end; { dummy } end. ============= ywin.pas END ===================== ============= testy.pas START ==================== program testy; import ywin; begin end. ============= testy.pas END ====================== ============ Compile log START ================ >gpc -c -g --unit-path=contrib ywin.pas >gpc testy.pas testy4.pas:3: `ywin.gpi' must be recompiled ============= Compile log END =================== If ywin.pas and testy.pas live in the same directory you can get around this problem by making testy.pas with --automake, but if they live in different directories that does not work. The problem goes away if gpc.* are put together with ywin.pas. I have not tested whether this is a particular problem of gpc.pas or whether it happens with any unit interface. Best regards, Bastiaan.
