Hi all,
I am fairly new to DMC and C++, and I a experiencing problems trying to
compile a simple hello.cpp program from \dm\stlport\hello.cpp

I followed the intructions from the readme.txt to build the stlport libaries and dlls, xcopied them as per instructions and am able to compile from command line ok.

I am running WinXP ( so not sure if this is a problem or not ? )

I start the SCW32mn.exe and get the IDDE up and running.

I then create a new dos project and add the hello.cpp file

Try to build it and get this error

sc hello.cpp -ms -C -S -3 -a2 -c -gf -ohello.obj
Fatal Error: O:\DM_FILES\hello.cpp(1): unable to open input file 'iostream'
Lines Processed: 1  Errors: 1  Warnings: 0
Build failed

Hmm a bit odd really, since I have included ..\stlport\stlport in the sc.ini file in the include path

Any help appreciated
Yeric

Why are you using SCW32mn.exe? I haven't used this version of the IDDE, I
use SCW32.exe and it runs fine on XP

Sorry sent my message too soon...coffee makes you hit keyboard shortcuts before needed...

You say that you successfully built stlport so, hmm. Are you including "C:\dm\stlport\stlport" before the normal include?

Like: INCLUDE="C:\dm\stlport\stlport";"%@P%\..\include";"%@P%\..\mfc\include";"%@P %\..\stl";%INCLUDE%

I had some trouble with the environmental variables version of the STLPort path (but I didn't give it much time, I was hasty). I have this setup and it works for me.

No should not be a problem.

With SCW32MN.EXE you are able to start the idde more than once. Might be handy when working on more than one project at the same time

This is the problem I guess. You should not create a 'dos' project but a 'Windows NT console'. In the project window use the ARROW KEYS to select the target type.

Also take a good look at sc.ini in the compiler bin drectory and make sure the settings are correct.

Well I am including this in the sc.ini file exactly as per readme

I am now using the SCW32 also now but it still doesn't work :(

I copied the dll and .lib files to the \dm\lib dir, the only thing I ave not done yet is reboted my machine, should I need to ??

I am going to play a bit more with it, for the moment the command line will suffice, but hopefully soon the IDDE will be most useful

Thanks
Yeric

Ok done this and when it loads the project I get this

No errors :)
but then I try and build and get this

And here is my sc.ini file

[Version]
version=7.51 Build 020

[Environment]
PATH=%PATH%;"%@P%\..\bin"
BIN="%@P%\..\bin"
INCLUDE="%@P%\..\stlport\stlport";"%@P%\..\include";"%@P%\..\mfc\include";"%
@P%\..\stl";%INCLUDE%
LIB="%@P%\..\lib";"%@P%\..\mfc\lib";%LIB%
HELP="%@P%\..\help"

And the source file

#include <iostream>

using namespace std ;

int main( void )
{
    cout << "Hello world!" << endl ;
}

Well for many hours now I have been battling with this one

If I change the <iostream> and append .h it works fine !!

This denotes a problem somewhere with my stlport configuration or does it ?since

dmc hello -I\dm\stlport\stlport \dm\lib\stlp45dms.lib -D_DLL works fine no errors

If I use sc instead of dmc I get this

*** Unrecognized Command ***
DESCRIPTION:
 SC is a command line program used for communicating with the
 NT Service Controller and services.
USAGE:
 sc <server> [command] [service name] <option1> <option2>...

 The option <server> has the form "\\ServerName"
 Further help on commands can be obtained by typing: "sc [command]"
 Commands:
   query-----------Queries the status for a service, or
                   enumerates the status for types of services.
   queryex---------Queries the extended status for a service, or
                   enumerates the status for types of services.
   start-----------Starts a service.
   pause-----------Sends a PAUSE control request to a service.
   interrogate-----Sends an INTERROGATE control request to a service.
   continue--------Sends a CONTINUE control request to a service.
   stop------------Sends a STOP request to a service.
   config----------Changes the configuration of a service (persistant).
   description-----Changes the description of a service.
   failure---------Changes the actions taken by a service upon failure.
   qc--------------Queries the configuration information for a service.
   qdescription----Queries the description for a service.
   qfailure--------Queries the actions taken by a service upon failure.

   sdset-----------Sets a service's security descriptor.
   GetDisplayName--Gets the DisplayName for a service.
   GetKeyName------Gets the ServiceKeyName for a service.
   EnumDepend------Enumerates Service Dependencies.

 The following commands don't require a service name:
 sc <server> <command> <option>
   boot------------(ok | bad) Indicates whether the last boot should
                   be saved as the last-known-good boot configuration
   Lock------------Locks the Service Database
   QueryLock-------Queries the LockStatus for the SCManager Database
EXAMPLE:
 sc start MyService

Would you like to see help for the QUERY and QUERYEX commands? [ y | n ]:
QUERY and QUERYEX OPTIONS :
 If the query command is followed by a service name, the status
 for that service is returned.  Further options do not apply in
 this case.  If the query command is followed by nothing or one of
 the options listed below, the services are enumerated.
    type=    Type of services to enumerate (driver, service, all)
             (default = service)
    state=   State of services to enumerate (inactive, all)
             (default = active)
    bufsize= The size (in bytes) of the enumeration buffer
             (default = 4096)
    ri=      The resume index number at which to begin the enumeration
             (default = 0)
    group=   Service group to enumerate
             (default = all groups)
SYNTAX EXAMPLES
sc query                - Enumerates status for active services & drivers
sc query messenger      - Displays status for the messenger service
sc queryex messenger    - Displays extended status for the messenger service
sc query type= driver   - Enumerates only active drivers
sc query type= service  - Enumerates only Win32 services
sc query state= all     - Enumerates all services & drivers
sc query bufsize= 50    - Enumerates with a 50 byte buffer.
sc query ri= 14         - Enumerates with resume index = 14
sc queryex group= ""    - Enumerates active services not in a group
sc query type= service type= interact - Enumerates all interactive services
sc query type= driver group= NDIS     - Enumerates all NDIS drivers

Now I am totaly confused stuck and frustrating

What have I done wrong ???

Start SCW32
Project->new
Hello.prj > Win NT
Add hello.cpp file
moans about some HELLO_DEF not added add anyway, I click no but it adds it
anyway
Makes no difference if it is in the project or not same compile error

build generates this file all the time

new.h

Is there some other .ini file I need to be poking at ??

Any help appreciated Please

Yeric

Ok I gave up in the end !!

Deleted Path from environemt
Deleted dm

Xcopied from CD again

Built stlport again!!

copied to \dm\lib *.lib and *.dll

opened project created an empty WIN NT console app used <iostream> and using namespace std ;

et voilla it compiled without a qualm

how odd is this ??

the only thing it moans about is when I reopen the project and it parses the files, it gives loads of warnings about the stlport .h files, but will still compile ok :)

However this I do not understand at all

dmc hello -I\dm\stlport\stlport \dm\lib\stlp45dms.lib -D_DLL = 34kb run from command line

so I decided to do a bit of experimenting and edited the sc.ini file, lib path and preceeded the first entry with this

\..\lib\stlp45dms.lib -D_DLL

thinking that this might have something to do with the .exe size but it doesn't, actually it increases the size by a few kb.

So I try building it as a dos exe, and dos com but they fail on the build something to do with the stlport libraries.

So can anyone tell me why there is such a difference in size between the command line compiled version and the IDDE version please ?

Does anyone know a way to other than setting optimizations for space or size, how to reduce exe size

Ilya Minkov in one of my previous posts suggested this from the command line

dmc hello.cpp -Nc -6 -o

but how to pass such arguments to IDDE ??? The make file somewhere ???

Thanks in advance for your patience and help on this
Yeric

Adding static libs or import libs to link against should be done in the IDDE: right click the project -> click 'settings...' -> click on the 'directories' tab. At 'Library Directories' add the direcory path for the libs you want to use seperate them with ;
Click OK
right click the project -> click 'Edit Project...' type the lib name and  extension in the 'file name' edit control click on 'Add'.
repeat for all libs you want to add to the project, don;t forget to click on OK.

You use different comilation options??

-Nc is function level link:
right click project -> 'Settings...' -> 'Build' tab -> 'Compiler -> Code Generation'

-6 is not supported in the idde, but you mat set this in the sc.ini file   Modify the CFLAGS and/or CFLAG= entry add -6

Ok thanks for the tips :)
I am still in the middle of reading the IDDE help files
>

Yes they are very different more options with the IDDE and none with the command line.

thank you again for your tips

I am not used to using and ide yet, everything I have done in the past has been with GCC via mingw32 comand line and basic make file

Thanks Yeric
