I have a legacy static library written in Pascal which I need to call from a C++ application targeting both PowerPC and x86 processors on the Mac OS X platform ( a so-called universal binary). After compiling and linking everything together, I'm having trouble calling the Pascal runtime libraries: i.e. I crash. Software used: glenn% gpc -v Reading specs from /Developer/Pascal/gpc345u2/lib/gcc/powerpc-apple- darwin8/3.4.5/specs Configured with: ../gcc-3.4.5/configure --enable-languages=pascal,c -- enable-threads=posix --target=powerpc-apple-darwin8 --host=powerpc- apple-darwin8 --build=powerpc-apple-darwin8 --prefix=/Developer/ Pascal/gpc345u2 Thread model: posix gpc version 20051116, based on gcc-3.4.5 gpc-i386 -vReading specs from /Developer/Pascal/gpc345u2/lib/gcc/i386- apple-darwin8/3.4.5/specs Configured with: ../gcc-3.4.5/configure --enable-languages=pascal,c -- enable-threads=posix --target=i386-apple-darwin8 --host=powerpc-apple- darwin8 --build=powerpc-apple-darwin8 --prefix=/Developer/Pascal/ gpc345u2 --with-sysroot=/Developer/SDKs/MacOSX10.4u.sdk/ --with- arch=pentium-m --with-tune=prescott Thread model: posix gpc version 20051116, based on gcc-3.4.5 Mac OS X 10.4.4 XCode 2.2.1 Source: 34 files of legacy Pascal which I've gone through and fixed all of the compiler errorss and most of the warnings. Steps I've taken. 1) Compiled and packaged using gpc, libtool, and lipo: gpc -c --automake -Wl,-framework,Carbon -funit-path=/Developer/Pascal/ GPCPInterfaces/ MySrc.p libtool -static *.o -o MyLibPPC.a rm *.gpi rm *.o gpc-i386 -c --automake -Wl,-framework,Carbon -funit-path=/Developer/ Pascal/GPCPInterfaces/ MySrc.p libtool -static *.o -o MyLibx86.a lipo *.a -create -output MyLib.a 2) Made a universal version of the gpc.a library lipo /Developer/Pascal/gpc345u2/lib/gcc/i386-apple-darwin8/3.4.5/ libgpc.a /Developer/Pascal/gpc345u2/lib/gcc/powerpc-apple- darwin8/3.4.5/libgpc.a -create -output gpc.a 3) Added both libraries to my XCode 2.2.1 C++ application 4) Compile and Links without running, crashes as soon as it tries to call WriteLn, if I remove the WriteLn, it crashes later in a call to the file routine Assign, which might be the first runtime library call. I declare the entry in C++ as: extern "C" short MyEntry(const char *path); In Pascal, I declare it as const MaxPointerChars = 20000; Type PAPointerChar=^APointerChar; APointerChar = Packed Array [0..MaxPointerChars] of Char; Int16 = Integer attribute ( size = 16); ... function MyEntry(DllPathC:PAPointerChar):Int16; attribute (name = 'MyEntry'); ... function MyEntry(aCString:PAPointerChar):Int16; var DLLPath:String2048; pathLength:Int32; i:Int32; begin pathLength := StrLen(aCString); if pathLength > 2048 then pathLength := 2048; DLLPath := ''; for i := 1 to pathLength do begin DLLPath := DLLPath + aCString^[i-1]; end; WriteLn(DLLPath); { crashes here} ... gdb gives me the following console output: Running… Program received signal: "EXC_BAD_ACCESS". Unable to disassemble _p_Write_Init. 5) I've written a little test application in Pascal to debug the libraries code (when it is not packaged as a library but compiled directly into the application) and the code works perfectly well in that environment. The debugging was done with XCode 2.1 as I believe there is a problem with gpc and XCode 2.2. So how do I fix this?
