Hi All
Have reall big problem...have project due out next week and now suddenly when i go to complile it get following compile error
"ERROR: GROUP DGROUP exceeds 64k"
Am really desperate to solve this as have tried everything!!!
Anybody seen this before
Thanks for any assistance
Mike
 

Thanks Andrue,
This program has developed over years and different people have added to it then in time left the company. So now ive been modifing it... Is their anyway of increasing the Dseg size as id never be able in the time left to me to do rewrite regarding finding all the arrays and modifing as you said.
This may be a stupid question on my part as am only a part time programmer as such, so knowledge is not the greatest.
Thanks for any assitance you give
Mike
 

Ms,
saw this sooner or later - your time has come :)
The problem is that you only have 64kB for static/global data and you
have just exceeded that.
There are at least two solutions:
1.Allocate your global variables on the heap and access them
through a static pointer.
2.Declare large structures as 'far'.

Ms,
IIRC the DSeg shares space with the stack so if you reduce the stack size you'll gain a
larger data area. I just hope you don't need a large stack.
One other possible solution is to look for a project option that is called something like
"far data size threshold". Any single entity bigger than that value automatically
becomes far and that moves it out of the DSeg.

Sorry to keep bothering people but....
Have found out about an -Ff command by surfing the net.
My understanding is that any any global data value above 9 will be put into the FARDATA segment.
This is my make file and have included it as shown below (-Ff=9)
---------------------------------------
# for Imake
#---------------------------------------
TARGET = ..\inspect.exe
INC = $x{*.h}
SRC = $x{*.c}
OBJ = ${SRC:.c=.obj}
CC = c:\borlandc\bin\bcc -ml -Ff=9 -c
LINK = c:\borlandc\bin\bcc -ml -e..\inspect
# .silent
${TARGET}: ${OBJ}
# .echo linking
$(LINK) ${OBJ} graphics.lib
.c.obj:
# .echo compile : $<
$(CC) $<
${OBJ}: $#.c ${INC}
Have tried different numbers ie -Ff=100 but no joy. Have very few arrays greater than 100.
Am I doing it correctly or is this even possible?
Really appeciate any time spent looking at my problem

running it in a 16 bit os (DOS or win3.x) you should be able to
recompile it as a 32 bit app and solve the problem. Otherwise, try
Andrue's suggestions.

Guys
My only hope seems to be the -Ff command. But have tried various options for -Ff ie
bcc -ml -Ff=20 -c
Every value for -Ff that I use does not seem to work.
Am I using it correctly above?
Getting really desperate
Am compiling in borland c++ version 3.1, am I in the wrong group, if so really sorry and which group would I be best to post this in?
Thanks for your patience guys

Ed......
I hope Im not being premature but deleted all the obj files as you said and recompiled with the -Ff=20 included.
THIS APPEARS TO WORK!!!!
Hopefully this is my problem solved.
Thanks all for your help. [My job is still safe :-)]
You hopefuuly won't be hearing from me again on this topic
Again Thanks
Ms

Try deleting all the object files and then making the project.

I am happy that it helped.
What happened is that you changed the option settings but did not recompile
the object files so the new setting did not take.
A Project|Build_All would have done the same thing.
