mingw - module/unit `gpc' could not be compiled
by Andreas Wirooks 20 Oct '06

20 Oct '06

Hello, i'm a beginner at MinGW and Pascal and i've downloaded and searched through the archived mailbox fo a long time but i found no solution. And generally i find no useful information for setting up mingw and gpc. I wanted to use the latest gpc snapshop and so downloaded the corresponding mingw files. I used the candidate ones that the MinGW 5.0.2 installation program because these are the only ones wich have gcc 3.4.4 wich is the latest gpc snapshot is based. So the files i installed in C:\MinGW are these: These were downloaded by MinGW 5.0.2 installation program mingw-runtime-3.8.tar.gz w32api-3.5.tar.gz binutils-2.16.91-20050827-1.tar.gz gcc-core-3.4.4-20050522-1.tar.gz gcc-g++-3.4.4-20050522-1.tar.gz gcc-g77-3.4.4-20050522-1.tar.gz gcc-ada-3.4.4-20050522-1.tar.gz gcc-java-3.4.4-20050522-1.tar.gz gcc-objc-3.4.4-20050522-1.tar.gz mingw32-make-3.80.0-3.tar.gz Theses i downloaded from MinGW.org download page in the current section: gdb-5.2.1-1.exe mingw-utils-0.3.tar.gz These from gnu-pascal.de: gpc-20051116.i386-pc-mingw32.tar.gz pdcurs24.beta-i386-pc-mingw32.zip gmp-2.0.2-i386-pc-mingw32.zip rx-1.5-i386-pc-mingw32.zip I found no other MinGW setupinformation than putting C:\MinGW\bin to the path. I already know that with the --automake --autobuild options because without these i got the "module/unit interface `GPC' could not be imported" error. But with one of these options i get the error listed in the subject line. Here is the output for "gpc -v --autobuild statfsdemo.pas -o statfsdemo.exe" wich is a demo program from the doc\gpc\demos directory: C:\MinGW\doc\gpc\demos>gpc -v --autobuild statfsdemo.pas -o statfsdemo.exe Reading specs from C:/MINGW/BIN/../lib/gcc/mingw32/3.4.4/specs Configured with: ../configure --with-gcc --with-gnu-ld --with-gnu-as --host=mingw32 --target=mingw32 --prefix=/mingw --enable-threads --disable-nls --enable-languages=pascal --disable-win32-registry --disable-shared --enable-sjlj-exceptions --without-x --enable-interpreter --enable-hash-synchronization Thread model: win32 gpc version 20051116, based on gcc-3.4.4 (mingw special) C:/MINGW/BIN/../libexec/gcc/mingw32/3.4.4/gpc1.exe -quiet -v -iprefix C:\MINGW\BIN\../lib/gcc/mingw32/3.4.4/ statfsdemo.pas -quiet -dumpbase statfsdemo.pas -auxbase statfsdemo -famtmpfile=C:\WINDOWS\TEMP/ccbxkigb.gpa -fautobuild -version -o C:\WINDOWS\TEMP/ccWldggb.s GNU Pascal version 20051116, based on gcc-3.4.4 (mingw special) (mingw32) compiled by GNU C version 3.4.4 (mingw special).

I remember, when i tried to learn c years ago (i tried to learn pascal with turbo pascal 6.0 12 years ago), that for emx (yes, the os/2 box is still lying around here) i had to setup many environment variables for the include and library pathes so that i was able to run it. I now compiled gpc.pas by hand and copied all files (.o, .gpi etc.) in the demos directory and it worked doing the commandline above. Can some hacker point me to the solution? I don't think that i have an broken installation. Befor this constellation i used different mingw's with nearly all gpc incarnations from gnu-pascal and mingw but this with this one i came at least to an exe file. Alles Gute and Thanks, Andy _________________________________________________________________ Sie suchen E-Mails, Dokumente oder Fotos?

static linking of libgpc
by Peter Norton 18 Oct '06

18 Oct '06

Hello, A few years ago I was managed to create dynamically linked executables with statically linked libgpc (or even only some objects from the lib the program used). Now I have needs to make it again but unfortunately I cann't recall the process :-( The only things I remember - the program was compilled as object first and then linked with ld to executable. I still have system.o and gpc.o in that program's folder and beleive they was involved in process somehow. Could anyone help me with ideas? Thanks in advance, Peter __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

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
