Hi,

I have the latest Cygwin/cygnome environment (Cygwin 1.5.5.1 dll) installed 
two weeks ago for compiling a working program already tested in linux and 
solaris. The program uses the X libraries Xt, Xpm, Xaw and X11 in an 
interface window written in C and runs a program written in Fortran.

I compiled the interface program written in C (xgraph.c) using gcc -x -o 
xgraph.o xgraph.c -I/usr/X11R6/include and it created the object file 
without problems.

I then compiled the fortran code and linked the libraries and required 
object files -including the C program- as I did in Linux (I just changed the 
paths for the includes and the libraries) and the names of the libraries ( 
-lXpm -> -lXpm.dll, -lX11 ->-lX11.dll). It compiled fine and I got my object 
dependencies ok and the exe file without problems. But, when I tried to run 
the program I got a "Program too big to fit in memory" error message and it 
didn't run. The program is 1.4 MB and my computer has 256 MB RAM and 9 GB 
hard disk free space (defragmented, i.e., single chunk).

I run the max_memory program included in Chapter 3 of the users manual I 
think, and it reports 1560 kB. So I'm discarding real memory problems.


I have tried:
1. increasing Cygwin memory restriction using regtool  for 
memory_chunk_in_mb to set 2048 kB. Nope.
2. compiling the code with -fconserve-space, -fno-inline, -Wl... heap and 
stack.... They Reduce the exe file size a bit, but still didn't work. 
Program too big to fit in memory.
3. stripping the exe file using strip -s <exe_file>. Reduces the size of the 
executable by 1/3 but still getting the same error message.

I run out of options, so I hope someone can give a hint what to do to make 
my program run.

Thanks,
