Hi,
I am trying to build a DLL library from a C code. I installed CygWin and
can compile and run the proverbial "Hello world" - just to get the feel
for it.
However, I do not have the makefile for building a DLL, nor have I been
able to find it by searching Google.
Does anyone have a working example that I could use?
On another note, I have not been able to run my hello.c program in debug
mode.
This is what I find in the log:
!ENTRY org.eclipse.cdt.launch 4 150 Dec 16, 2002 15:15:17.155
!MESSAGE Failed Launching CDI Debugger : Error initializing: Timedout
!STACK 0
org.eclipse.cdt.debug.core.cdi.CDIException: Error initializing: Timedout
at
org.eclipse.cdt.debug.mi.core.GDBDebugger.createLaunchSessio n(GDBDebugger.java:49)
...
What am I missing?
Any clues will be greatly appreciated.

You should read the FAQ at www.mingw.org
It will answer most of your questions about DLL building. The MinGW and
Cygwin tools share the same back-end. (GCC), but unless you need/want a
POSIX emulation layer, MinGW is probably the better choice.
Make sure that the -g option is set in your build command (the gcc line, not
the make line) to build a debug version of your code.

Thanks. I installed MinGW and followed your advice. The DLL is built
allright, and I can execute my testcase, but debugging through Eclipse is
still a problem. I am getting different errors, depending on my Debug
settings.
When I select "GDB Debugger" in the Debugger tab of the Launch
Configurations window, and try to start the Debug, an attention panel pops
up: "Exception occurred while launching configuration. See log for more
information. Reason: failed launching CDI Debugger: No symbol table is
loaded. Use the "file" command."
And this is the log:
!ENTRY org.eclipse.debug.ui 4 120 Dec 17, 2002 16:06:18.359
!MESSAGE Error logged from Debug UI:

I tried selecting "Cygwin GDB Debugger" option, but this does not work
either, bringing up the following attention panel: "The execution of
program is suspended because of error". The detail message is: "No
executable specified, use 'target exec'".
The log in this case is empty.
Interestingly enough, both times the gdb.exe process is launched - I can
see it in my Task Manager window.
Perhaps you or someone else knowledgeable in CDT/Debug interaction can
glimpse something peculiar in the above traceback that I fail to see. In
particular, what is this "file" command the Debugger is complaining about?
