Tobi (20/20) Jul 05 2003 ok, I'm just starting with C++ and Compilers are new to me.

I read that you have to do path variable setting or something like that.

What exactly is that?

I just unzip an copied everything to C:
in the dos-enviroment I can start the dmc.exe with the following path:
c:\dm\bin\dmc

but if I try:
c:\dm\bin\dmc test

I get the following error:
Fataf error: unable to open input file 'test'
---errrorlevel 1

my test-file has the ending test.cpp and looks as followed:

#include <iostream>
using namespace std;

int main()
{
cout << "Testing 1, 2 ,3\n";
return 0;
}

for some help I would be very thankful...

Well in your dos environment, which actually will be a win32 command 
prompt or 'console' when you are using NT/2000/XP, type:
C:\>set

Somewhere along those lines you will see:
Path=C:\WINNT\System32..................

This setting defines which directories will be searched when issueing a 
command not found in the current directory.

To set your path environment variable only for the current Console type:
c:\>set path=C:\dm\bin;%PATH%
Check the change with
c:\>path
and voila there it is now you can type dmc in any directory and it will 
be executed.

To make this path setting permanent consult your OS help.

To compile test.cpp you have to type:
dmc test.cpp

Good Luck
Arjan Knepper

Hi Arjan,

thanks a lot so far. I have to admit that I never worked with the console
earlier.

To set the path variable worked I guess, since I can start the dmc.exe now
without typing a path... just dmc

but still it doesn't open the test.cpp which is in the same folder as the
dmc.exe and just gives out the same error as before(unable to open input file).
do I have to do something special with the file (save it in a certain way,...)
or... 

I didn't do anything else than extracting the zip-file to C:

I'm very thankful for help... and if you explain, just think of me as a 4 year
old ;))

dmc looks for your program in the "current working directory", the directory
you set with the CD command from a command prompt. dmc does not look in the
directory that dmc.exe resides.

If the file is in your C:\dm\bin directory you need to type:

dmc c:\dm\bin\test.cpp

You could also make a directory for your small programs, type:

cd \
mkdir cpp
move c:\dm\bin\test.cpp c:\cpp
cd c:\cpp
dmc test.cpp

This way you won't clutter your digital mars hierarchy with objects and
unrelated source(.c, c.pp) and executables(.exe)

directory
 you set with the CD command from a command prompt. dmc does not look in

If you download the Environment Expander (NVX) tool from the system tools
page on my website - http://synesis.com.au/r_systools.html - you'll find
that it helps you see what is in your environment a lot easier. For example,
if you type

 nvx -i -l -p

that gives you a tokenised list of INCLUDE, LIB and PATH environment
variables, which for C/C++ developers are very useful. Doing that on my
system within a DMC++ setup gives

INCLUDE:
H:\STLSoft\Identities\STLSoft\stlsoft
P:\PROGRAMS\DM\beta\DM\include
P:\PROGRAMS\DM\beta\DM\include\win32
P:\PROGRAMS\DM\beta\DM\stl
P:\PROGRAMS\DM\beta\DM\mfc\include
LIB:
P:\PROGRAMS\DM\beta\DM\lib
PATH:
P:\PROGRAMS\DM\beta\DM\BIN
F:\WINXP\system32
F:\WINXP
F:\WINXP\system32\WBEM
P:\Program Files\Metrowerks\CodeWarrior\8.0\Other Metrowerks Tools\Command
Line Tools
P:\Program Files\Metrowerks\CodeWarrior\8.0\Win32-x86
Support\Libraries\Runtime\Libs\MSL_All-DLLs
P:\Program Files\Metrowerks\CodeWarrior\8.0\Win32-x86

P:\SDKs\Microsoft SDK\Bin
P:\SDKs\Microsoft SDK\Bin\WinNT
X:\bin
c:\bin
P:\Program Files\doxygen\bin
P:\Programs\ActiveState\Python22
P:\Programs\ActiveState\Perl\bin

You can also type in any other environment variable you fancy, as in

H:\>nvx VJSHARPTOOLS

F:\WINXP\Microsoft Visual JSharp .NET\Framework\v1.0.4205

There are other useful parts to it. For example, it can copy the items to
the clipboard, and it can highlight missing directories in environment
variables, as in

H:\>nvx -p -x
P:\PROGRAMS\DM\beta\DM\BIN
F:\WINXP\system32
F:\WINXP
F:\WINXP\system32\WBEM
P:\Program Files\Metrowerks\CodeWarrior\8.0\Other Metrowerks Tools\Command

P:\Program Files\Metrowerks\CodeWarrior\8.0\Win32-x86

P:\Program Files\Metrowerks\CodeWarrior\8.0\Win32-x86
Support\Libraries\MFC\Libs

P:\SDKs\Microsoft SDK\Bin\WinNT
* X:\bin
c:\bin
P:\Program Files\doxygen\bin
P:\Programs\ActiveState\Python22
P:\Programs\ActiveState\Perl\bin

Indicating that X:\bin does not exist.

Hope that helps
