newbie: Why Cygwin/Egcs compiled executable is so bloated

newbie: Why Cygwin/Egcs compiled executable is so bloated

[Luke Liu]

I understand that it is not as easy to work with dll with cygwin as with
Visual C++ or Borland C++.  However, when I compiled the Hello world program
generated by Visual C++ 6.0 wizard with Cygwin B20.1, the executable was
530KB, meanwhile the mingw32 build was 315KB. Then I got the egcs2.95.2 and
after renaming old lib for mingw32 by watching the gcc include/lib search
path, I was able to reduce the executable of hello.exe with mingw32 to
173KB. The size with Cygwin remains > 500KB.

The compiler switch I used were
	gcc -Os -mwindows -v -mno-cygwin -e _mainCRTStartup
and 
	gcc -Os -mwindows -v -e _mainCRTStartup

respectively. Am I simply didn't enable the correct gcc switch? BTW, the
VC++6.0 compiled debug executable is 157KB and the released version should
be much smaller.
Thanks,

Luke

P.S. I found that due to some screwed security of something, I cannot post
to the solutioncentral from company. :-(((

Actually, you did post to solutioncentral three times. :-)

Here is my answer:

By default, gcc adds debugging information to every executable.  To
remove this you can either add a '-s' to the gcc command line or use the
strip command on the resulting executable:

strip file.exe

This should greatly reduce the size of the executable.
