Hello NG,

i've some big problems with the DM C++ Compiler ... i have portted a project
from Watcom 11.X to DM. This Project uses the DosExtender.
Now when i build the Program in the final step following errors occurs :

cx.obj ..... Symbol Undefined __x386_start
cx.obj ..... Symbol Undefined __x386_data_16_alias
cx.obj ..... Symbol Undefined __x386_dbg_hook
cx.obj ..... Symbol Undefined __x32_link_in_x32_lib

sdx.lib ..... Symbol UnDefined __x386_memlock
sdx.lib ..... Symbol UnDefined __x386_memunlock

Can you help me ???
Thx

Those are defined in cx.obj and sdx.lib. cx.obj has to appear first in the
command to the linker.

i have the dosextender ;-) i found the mistake ... i have forgotten to link
the x32.lib to the project ....

Now the project is built but i can't start it ... when i call it then
nothing happend.

Source :

#include <iostream.h>

void main(void)
{
    cout << "Hello World!" << endl;

}


OS : DOS 6.22 .... RAM 256 MB .... conv Mem : 487 kb .

config.sys :

device=c:\dos\himem.sys
rem device=c:\dos\emm386.exe /noems
BUFFERS=30
FILES=40
STACKS=9,256
LASTDRIVE=Z
dos=high,umb
SHELL=c:\COMMAND.COM c:\ /P /E:1024
rem devicehigh=C:\NET\ifshlp.sys


autoexec.bat :

echo off
PATH = c:\;c:\dos;c:\tools;c:\novell;c:\spc4
\dos\KEYB GR,,\dos\KEYBOARD.SYS
\dos\doskey
prompt $p$_$g

Thanks

I have no clue. What exactly is the command you use to build and link? Also,
try using printf instead of iostream.
