Mac OS X Pascal Interfaces version 2.1
by Adriaan van Os 06 May '08

06 May '08

Updated Mac OS X Pascal Interfaces, version 2.1 (release H), can be downloaded from <http://www.microbizz.nl/gpc.html>. The direct link is <http://www.microbizz.nl/GPCInterfacesH.dmg> The installer package contains Mac OS X Pascal interface units for GNU Pascal, FreePascal and MetroWerks CodeWarrior Pascal. A lot of work went into this new release, units were added or updated and several bugs have been fixed. There are now 330 Pascal interface units. For GPC on Mac OS X, this release requires the recently released gpc346u2 compiler (and a soon-to-be released new GPC Xcode kit). Please report bugs to <gpc(a)microbizz.nl>.

pascal strings in the gnu assembler
by steven.borley 05 May '08

05 May '08

Hope this is not considered too off-topic as it about the gnu assemble (gnu-as). I beg forgiveness on grounds that's its Pascal related. In my assembly code I'm trying to place string constants in memory (length byte followed by ASCII string with no trailing zero byte) The following is failing with "Error: illegal relocation size: 1" FOO: .byte ((BAR - . - 2) & 0x7F) ; calculate length .ascii "foo" BAR: .word 0x1234 ; dummy for this example I could just hard code the length, except I eventually want this as macro as I have several hundred strings. And unfortunately this part of the code has to be in assembler, for various reasons. I assume the error is because ((BAR - . - 2) & 0x7F) resolves to a two byte type even although we can see its value would always fit within a byte. It didn't seem a particularly unusually thing to want to do so I'm hoping someone can point me in the right direction with this. Regards, Steven

GPC Home Page

Hi, The following page is top of the list when you Google "GNU Pascal Compiler". http://www.gnu-pascal.de/gpc/h-index.html The copyright on the page has not been updated since 2005. The most recent version of GPC available on the site is 20041017. When I look for GPC, I end up finding it in three different places: one for MacOS (I have 20051116), one for Linux (I use 20041017), and one for Windows (I have 20070904 for MinGW). My cross-platform code has to include compiler directives like this: {$ifdef __GPC_RELEASE__} {$if __GPC_RELEASE__ > 20050000} {$define INIT_CALL '_p__M0_init'} {$else} {$define INIT_CALL 'init_pascal_main_program'} {$endif} {$else} {$define INIT_CALL 'init_pascal_main_program'} {$endif} procedure initialize_main; external name INIT_CALL; Where can I get the latest GPC binaries for MacOS, Linux, and MinGW? If the binaries are not available, where can I download the latest source files? Yours, Kevan -- Kevan Hashemi, Electrical Engineer Physics Department, Brandeis University http://alignment.hep.brandeis.edu/

Building latest gpc on Intel OS X 10.5.2
by Peter Schorn 28 Apr '08

28 Apr '08

I'm trying to build the latest gpc (gpc-20070904.tar.bz2) with Adriaan's patches on a Macintosh OS X 10.5.2. with Intel. I configure with ../gcc-4.1.2/configure --enable-languages=pascal,c --enable-threads=posix --prefix=/Developer/Pascal/gpc412 but the "make bootstrap" fails with Undefined symbols: "___sysctl", referenced from: ___enable_execute_stack in _enable_execute_stack_s.o ld: symbol(s) not found /usr/bin/libtool: internal link edit command failed make[3]: *** [libgcc_s.dylib] Error 1 make[2]: *** [libgcc.a] Error 2 make[1]: *** [stage1_build] Error 2 make: *** [bootstrap] Error 2 What am I missing?

compiling static library + gpc runtime without _statvfs on Mac OS X for Intel
by Glenn Howes 20 Apr '08

20 Apr '08

Hello, After months of being distracted by another portion of my application, I'm back to creating a universal binary version of the Pascal based library we are linking into our C++ based application. The problem is the application will not launch under PPC on Mac OS X 10.3 (Panther). The console registers an undefined symbol: _statvfs expected to be defined in /usr/lib/libSystem.B.dylib After some research, I found this call is being used by the StatFS routine implemented in rts.c (line 1510) /** Get information about a file system. */ GLOBAL (Boolean _p_StatFS (char *Path UNUSED, StatFSBuffer *Buf)) { int Result; #ifdef HAVE_STATVFS struct statvfs b; errno = 0; Result = statvfs (Path, &b); Buf->BlockSize = (long long int) b.f_frsize; Buf->BlocksTotal = (long long int) b.f_blocks; Buf->BlocksFree = (long long int) b.f_bavail; Buf->FilesTotal = (int) b.f_files; Buf->FilesFree = (int) b.f_favail; #elif defined (HAVE_STATFS) struct statfs b; errno = 0; Result = statfs (Path, &b); Buf->BlockSize = (long long int) b.f_bsize; Buf->BlocksTotal = (long long int) b.f_blocks; Buf->BlocksFree = (long long int) b.f_bavail; Buf->FilesTotal = (int) b.f_files; Buf->FilesFree = (int) b.f_ffree; #else Result = -1; errno = ENOSYS; #endif if (Result == 0) return True; Buf->BlockSize = 0; Buf->BlocksTotal = 0; Buf->BlocksFree = 0; Buf->FilesTotal = 0; Buf->FilesFree = 0; return False; } It appears to me that HAVE_STATVFS is defined if my current OS X SDK (10.4) has a statvfs.h header file amongst its include files, which means if I build my Pascal development environment from the build-on- Intel.command that the statvfs version will be hard wired into the runtime and any binary I generate will not work on 10.3 (which does not have statvfs in its libSystem.B.dylib library). Also, if I build my environment/library on a PowerPC using the build-on- powerPC-10.3.command, I end up with a different set of link problems involving the long double version of pow(). Besides which, I'd prefer to do my development on OS X for Intel going forward. I have tried hand editing the above routine and rebuilding my Pascal development environment, and pulling the statvfs.h file from my OS X SDK, and yet when my application links, it still has an unresolved reference to _statvfs. I'm not a build engineer, as my previous missives to this mailing list make clear, and I'm at a loss as to how to proceed. Just to be clear, I link in two static libraries: a universal version of the libgpc.a for the runtime, and a universal version of the library I've created. Neither of them contain the symbol _statvfs (at least I can't find that text in them). I link that with my application. The application now references _statvfs (I can now see the text in it's executable). I can't launch on 10.3. I comment out the calls to the Pascal library and recompile+relink, and the application no longer has the symbol and I can launch under 10.3. So something in either of the gpc associated libraries must be calling something which calls statvfs, making the linker (ld) mark statvfs as an unresolved symbol to be loaded in at runtime. At least that is my impression. So, I'd appreciate some suggestions. --glenn
