This small example program is not working. I have a feeling dmc does not link header files to there cpp files automaticly. If someone could clue me into what settings I need to make this test file work that would be sweet. There are 3 files: main.cpp, mine.h, mine.cpp CODE:: // main.cpp //--------------------------------- #include <cstdlib> #include <iostream> #include "mine.h" using namespace std; int main(int argc, char *argv[]) { int x = foo(); cout << x << endl; system("PAUSE"); return EXIT_SUCCESS; } //mine.h //------------------------ #ifndef _MINE_H #define _MINE_H int foo(); #endif // mine.cpp // ------------------ #include "mine.h" int foo() { return 5; } I get this error when I try to compile with dmc main.cpp C:\>dmc main.cpp link main,,,user32+kernel32/noi; OPTLINK (R) for Win32 Release 7.50B1 Copyright (C) Digital Mars 1989 - 2001 All Rights Reserved main.obj(main) Error 42: Symbol Undefined ?foo YAHXZ (int cdecl foo(void )) --- errorlevel 1 begin 644 error.txt M+VYO:3L-"D]05$Q)3DL *%(I(&9O<B!7:6XS,B` 4F5L96%S92`W+C4P0C$- M(%-Y;6)O;"!5;F1E9FEN960 /V9O;T!`64%(6%H *&EN="!C9&5C;"!F;V\H ` end begin 644 code.zip M```(`*:+1C:N'Z<8IP```-T````(````;6%I;BYC<'!-S,L*PC`0!=!](/\P M)279S[3UP2EA_I$9C6K>,THHB5YC!RB,\A<A%:07Q> :`QBA,1^+<)V< >R% M"````&UI;F4N8W!P4\[,2\XI34E54,K-S$O5RU#BY>+ERLPK44C+S]?05*CF M. ````8``````````0` `````````&UI;F4N:%!+`0(4"Q0````(`*:+1C:N M'Z<8IP```-T````(``````````$`(````%0```!M86EN+F-P<%!+`0(4"Q0` ` end

I C++ (and C) there is not necessarily any connection between the name of some .h file and some .cpp file.I get this error when I try to compile with dmc main.cpp C:\>dmc main.cpp link main,,,user32+kernel32/noi; OPTLINK (R) for Win32 Release 7.50B1 Copyright (C) Digital Mars 1989 - 2001 All Rights Reserved main.obj(main) Error 42: Symbol Undefined ?foo YAHXZ (int cdecl foo(void ))You need to list all the .cpp files on the commandline: dmc main.cpp mine.cpp -- Just another homepage: http://damb.dk But it's mine - Bertel
