7c2 Subj : Error: Unresolved external To : borland.public.cpp.borlandcpp From : "lasombra" Date : Wed Feb 18 2004 02:54 pm In the internet i found several descriptions of that problem, but nothing helped me. I use BCC 5.5.1, installed in "D:\Developement\C & C++\BCC552". The file bcc32.cfg is configured as follow: -I"D:\Development\C & C++\BC551\include" -L"D:\Development\C & C++\BC551\lib";"D:\Development\C & C++\BC551\Lib\PSDK" The file ilink32.cfg is configured as follow: -L"D:\Development\C & C++\BC551\lib";"D:\Development\C & C++\BC551\Lib\PSDK" The file I want to compile is DIBmain.cpp, which contains something like that: #include "stdafx.h" #include "DIB.h" #include "Image.h" #include "RGBtoHLS.cpp" int main(int argc, char* argv[]) { .... } The inluded files are in the same directory as the DIBmain.cpp (E:\DEVELOPMENT\C++\FACEREC\), and all OBJ-Files are generated. But I get the following error: Turbo Incremental Link 5.00 Copyright (c) 1997, 2000 Borland Error: Unresolved external 'Image::~Image()' referenced from E:\DEVELOPMENT\C++\FACEREC\DIBMAIN.OBJ Error: Unresolved external 'DIB::~DIB()' referenced from E:\DEVELOPMENT\C++\FACEREC\DIBMAIN.OBJ Error: Unresolved external 'DIB::DIB(char *)' referenced from E:\DEVELOPMENT\C++\FACEREC\DIBMAIN.OBJ Error: Unresolved external 'DIB::operator Image *() const' referenced from E:\DEVELOPMENT\C++\FACEREC\DIBMAIN.OBJ Error: Unresolved external 'Image::Image(Image::ImageType, int, int)' referenced from E:\DEVELOPMENT\C++\FACEREC\DI BMAIN.OBJ Error: Unresolved external 'Image::getPlane(int)' referenced from E:\DEVELOPMENT\C++\FACEREC\DIBMAIN.OBJ Error: Unresolved external 'DIB::DIB(Image *)' referenced from E:\DEVELOPMENT\C++\FACEREC\DIBMAIN.OBJ Error: Unresolved external 'DIB::SaveAs(char *)' referenced from E:\DEVELOPMENT\C++\FACEREC\DIBMAIN.OBJ I'm not an advanced C++ programmer, so can anybody help me? Where's the problem? . 0
