porting from sun (pc,cc) to gnu(gpc,gcc)compilers
by vanam srihari kumar 26 Oct '05

26 Oct '05

I will clearly explain our present software structure in solaris and how the exporting/importing will takes place. It consists of hundreds of modules and programs written in C and Pascal ,functions interaction will be in below combinations a) C functions defined in C Programs will be called from Pascal Modules and Programs b) Pascal functions defined in One Pascal module will be called from other Pascal Modules and Programs I)PASCAL MODULE STRUCTURE a)MODULE XXXX /* module name xxxx */ b)… [View More]

ANN: SQLite3 Unit
by Eike Lange 25 Oct '05

25 Oct '05

Hi Folks! Welcome to the wonderful world of SQLite3. SQLite3 is a library that implements an SQL database engine. The database is stored in one file, not in many files and the engine itself is not a kind of server, which makes it interesting for me to put my databases in such files. See http://www.sqlite.org/ for more details. I've written a unit which is an interface to SQLite3. You may download the unit from http://www.gnu-pascal.de/contrib/eike/sqlite3-gpc-20051025.tar.gz Eike

Dear All Is it possible to have export clause at the end of module/program in gpc version 2.1 as my porting will becomes much easier regards Hari __________________________________ Yahoo! FareChase: Search multiple travel sites in one click. http://farechase.yahoo.com

I want to write a macro which should compatible with gpc version 2.1 and look like below #define PAS_EXTERNAL_C(X) asmname 'X' suppose if i define a macro like above, it should be preprocessed like below Before preprocessing: procedure Hello; PAS_EXTERNAL_C(Hello); After preprocessing: procedure Hello; asmname 'Hello'; I am worried why #define PAS_EXTERNAL_C(X) asmname 'X' this is not working? Please help me Regards Hari __________________________________ … [View More]

I just checked that Free Pascal accepts the followig program: program keyw; var absolute, external, overload, override, virtual, abstract, reintroduce : integer; begin end . gpc -fdelphi says: keyw.p:2: error: `absolute' is a keyword in Borland Pascal keyw.p:2: error: `external' is a keyword in UCSD Pascal, Borland Pascal, keyw.p:2: error: traditional Macintosh Pascal keyw.p:2: error: `virtual' is a keyword in Object Pascal, Borland Pascal, keyw.p:2: error: traditional Macintosh … [View More]

LastReadWriteStrFDR memory leak
by Peter N Lewis 22 Oct '05

22 Oct '05

LastReadWriteStrFDR is used to cache an FDR to avoid allocating and releasing one for each use of ReadStr, Val etc. Unfortunately, the memory is leaked since it is never freed and there is no way to cause it to be freed. This causes my leak detection routines to fire on termination of my program. I've added to files.pas: procedure DisposeReadWriteStr; attribute (name = '_p_DisposeReadWriteStr'); procedure DisposeReadWriteStr; begin if LastReadWriteStrFDR <> nil then begin … [View More]

compiler flags explanation
by vanam srihari kumar 18 Oct '05

18 Oct '05

Thanks for the reply I am using below compiler flags PFLAGS = -L -w -tc -fnonstd -ftrap=%all -DSOLARIS -DL_SOLARIS -Qoption cpp -C -Qoption cpp -DSOLARIS Please find below the explanation of unavailable flags in gpc -fnonstd -fnonstd = The -fnonstd option causes nonstandard initialization of floating-point arithmetic hardware. By default, IEEE 754 floating-point arithmetic is nonstop, and underflows are gradual. (See the Numerical Computation Guide for details.) The -… [View More]fnonstd option causes hardware traps to be enabled for floating-point overflow, division by zero, and invalid operation exceptions. These hardware traps are converted into SIGFPE signals, and if the program has no SIGFPE handler, it terminates with a memory dump. -fnonstd also causes the math library to be linked in by passing -lm to the linker. This option is a synonym for -fns -ftrap=common. -tc -tc =The -tc option instructs the compiler to generate pc3 stab information that allows cross-module type checking. This option can be used for two purposes: To check for any name conflicts that your program may have with the standard libraries with which it is to be linked, such as libc. The linker allows name conflicts, which may cause erroneous runtime behavior in your program. For example, the following program has a name conflict with libc: program p(output); var time: integer; begin writeln(wallclock); end. When the program is compiled with the -tc option, pc3 issues a warning that the name time is already defined as a libc routine. Running a.out causes a core dump. To avoid this problem, change the name of the variable that has the conflict--in this case, time. To check for possible name conflicts in the various modules of your program. These conflicts arise if you define a routine with the same name in several modules, or refer to an external, but undefined, variable. The linker detects these error situations and does not create the executable file. hostname% {$w-} -Qoption The -Qoption passes an option to the program. The option value must be appropriate to that program and can begin with a plus or minus sign. The program value can be either cpp(1), cppas, iropt, ld(1), ild(1), pc0, or pc3. For example, the following command passes the option -R to cpp and allows recursive macros: hostname% pc -Qoption cpp -R myprog.p Regards Hari __________________________________ Yahoo!

gpc compiler problem
by vanam srihari kumar 17 Oct '05

17 Oct '05

Dear All I am trying to make use of gpc compiler(2.1 version) in solaris 2.8 platform.For testing purpose I have written two sample programs,one for creating a module and another is a program. program will call the function defined in the module. I am compiling those programs by make use of a make file. When I am trying to call a function from library it is giving linking problem.Below I am pasting the code and make file.Please correct my code sothat it facilitates me to call the function … [View More]
