Hello,
I am having great fun with Eclipse, CDT and CGYWIN on Win2K.
I downloaded the latest stable versions about 15 days ago.
Even though my experience is really limited I could compile and run a
simple project.
I wrote the following .mak
************************************************************
Prj1 : Prog1.o
gcc -O Prj1 Prog1.o
Prog1.o : Prog1.c
gcc -ggdb -O Prog1.c
all :
make -f prog1.mak
..PHONY : clean
clean :
-del Prj1.exe -del *.o
****************************************
the project is compiled and runs correctly in native mode.
When I try to debug it I can stop the execution at the main()
but when I look at the gdb console I get the following:
************************************************************ **
info threads
No stack.
No symbol table is loaded. Use the "file" command.
info threads
2 thread 1412.0x9d4 * 1 thread 1412.0x588
************************************************************ ***
I'd appreciate any help.
Thank in advance
Sandro

up to the completion.
Thank you,

Thank you Mikhail for the quick response!!
I did as suggested but unfortunately there are no changes.
Now the gdb console shows the following:
------------------------------------------------------------ ------
info threads
No stack.
No symbol table is loaded. Use the "file" command.
info threads
2 thread 2472.0x9bc * 1 thread 2472.0x8b4 No symbol table is
loaded. Use the "file" command.
Single stepping until exit from function main,
which has no line number information.
------------------------------------------------------------ ---------
while the program is still running in suspended mode.
Thank you for your patience!!

Mikhail, please forgive me as I sent some misleading info.
First this is my current makefile:
------------------------------------------------------------ -----
Prj1 : Prog1.o
gcc -o Prj1 Prog1.o
Prog1.o : Prog1.c
gcc -ggdb -o Prog1.c
all :
make -f prog1.mak
..PHONY : clean
clean :
-del Prj1.exe -del *.o
------------------------------------------------------------ ----------
When I started this thread I used the -O and I could get a clean build
but I was missing debugging info.
Then you suggested to use -o I did it and I tried again, but I didn't
build correctly the project again, so in fact the second time I used the
very first build.
Whne I deleted .o and .exe and rebuilt with -o I didn't get a clean
build and the messages I get are as follows:
------------------------------------------------------------ ----------
***(all) Error 2
***(Prog1.o) Error 1
------------------------------------------------------------ ----------
Maybe the installation of CGYWIN is not correct but I don't know how to
go further.
Thank you again,
Ciao

Your Makefile is awefully filled with mistakes!
* -O is for optimizations --> -o <file> is for "output into <file>"
* your target Prj is missing an extension! in you clean rule you wrote
it right
* The first target in you Makefile is 'Prj1', and your 'all' rules is
way below and looks really useless, since Eclipse calls the build
process this way:
make clean
make
Here is a more proper Makefile:

Thank you!!!
I modified your makefile and could consistently build my test program.
Unfortunately I still cannot run the program step by step nor
stop at breakpoints.
I did also the following:
- copied the files ( .c and .mak ) into the native cygwin environment
- built the program again
- compared the size of the .exes : they are the same.
- then I rebuilt ( in cygwin ) the program WITHOUT the -g or -ggdb
options and THE SIZE REMAINS THE SAME!!!
No Debugging info are added in either cases.
So, it looks like a problem in cygwin.
I subscribed to the cygwin@cygwin.com but I have problems because my
e-mails are rejected.
I'll try anyway to reach that mailing list.
Thanks to all for the helpful info.
ciao

The first is by myself :(
In the top ifeq... the elsis must be written as:
else
ifeq ($(TargetArch),"Unix")
....
endif
endif
since make does not recognize nested conditional statements.
The second mistake is yours.
In the debug: -rule, their is no "C_DEBUG=", since this would clear out
this variable!
Thats why I added it just in the 'all'-rule, where you dont want debug
infos usually.
The make command in the debug-rule should be:
<tab>$(MAKE) $(PROG1)
Also, if you set .DEFAULT: debug, you dont need to move the debug rule
above the all-rule.

when you try to debug within CDT, it is because there are spaces in the
path to your project. Move the project to a path without spaces, or move
the entier Eclipse install to a path without spaces and it should work. I
was tearing my hair out over the same problem.
