Detailed Description

One of the original OpenC++ source files, considerably modified by Josef Troch.

This file contains platform dependent functions of the original OpenC++ plus a few new platform dependent functions added by Josef Troch.

Functions from this file are used on Linux / gcc platform. The same functions for Windows / MSVC platform can be found in driver2.cpp.

Only functions added or modified by Josef Troch are commented.

Define Documentation

#define lt_dlhandle void *

#define PREPROCESSOR_EXT ".i"

Extension of files generated by preprocessor.

#define TRANSLATOR_EXT ".ii"

Extension of files that are the results of IOPC SP / OpenC++ translation.

#define SLIB_EXT ".so"

#define OBJ_EXT ".o"

Function Documentation

int execvp ( ... )

int wait ( int * )

void ParseCmdOptions ( int from,

int argc,

char ** argv,

char *& source

)

void AddCppOption ( const char * arg )

void AddCcOption ( const char * arg )

void CloseCcOptions ( )

void ShowCommandLine ( const char * cmd,

const char ** args

)

bool ParseTargetSpecificOptions ( char * arg,

char *& source_file

)

void RunLinker ( )

char* RunPreprocessor ( const char * src )

Runs preprocessor (g++ / cpre) on file_in.

Returns:
Name of the file that contains preprocessor output. (The name is generated using MakeTempFilename().)

See also:
PREPROCESSOR_EXT, SetTargetDirectory()

char* OpenCxxOutputFileName ( const char * src )

void RunCompiler ( const char * org_src,

const char * occ_src

)

Runs compiler (g++) on occ_src.
Sends the compiler the parameters specified when executing IOPC SP / OpenC++ (only the "compiler" options). Adds to them some parameters specified by IOPC SP / OpenC++ options, if called from IOPC SP adds some parameters needed for translated source to compile (two bytes wchar_t support).

Parameters:

org_src The original (not translated) C++ source file name. Used in OpenC++ if generating shared library.

occ_src Name of the translated C++ source file - input for the compiler.

See also:
SetTargetDirectory()

void RunSoCompiler ( const char * src_file )

lt_dlhandle LoadSoLib ( char * file_name )

void * LookupSymbol ( lt_dlhandle handle,

char * symbol

)

void RunSoLinker ( const char * org_src,

char * target

) [static]

char * MakeTempFilename ( const char * src,

const char * suffix

) [static]

Creates temporary filename from given filename (src) and extension (suffix).
Rewritten by JT - uses targetDir now..

See also:
SetTargetDirectory()

Returns:
The filename.

void SetTargetDirectory ( const char * dirPath )

Sets path (targetDir) into which files generated by IOPC SP / OpenC++ should be placed.
Sets drive and directory (targetDrive, targetDir) into which files generated by IOPC SP / OpenC++ should be placed.
