Hi,
I'm using CDT 3.0.0 & Cygwin/gcc/g++ on WinXP.
I believe I'm trying to dynamically link to shared libraries... ie I've
checked Project Properties->C/C++ Build->GCC C++ Linker->Shared Library
Settings->Shared checkbox. The other fields on this page (eg. shared
object, import library name) are empty however.
When I look at the Modules panel whilst debugging I see that cygwin1.dll
is listed as well as a few others.
However, when I build my executable is 554KB. When I build a Release
version, it is around 440KB. I'm sure that it is to do with static
linking of libraries, because when I compare it with a significantly
more complex application build using MSVC++ dynamically linked to
libraries, the application is only 50KB.
Could anyone please give me some help on how to configure Eclipse CDT to
work with Cygwin/gcc to dynamically link to libraries properly please?
Thanks very much for your help.
PretzelX.

Not necessary. You can't really compare codes generated from different
compilers.
Anyway. First thing to do would be to strip the executable file (strip
<name_of_file> ). It should slim your exec a lot of kilobytes.
Also I would recommend browsing through gcc (g++) manual to find out
what other options you have when compiling/linkg C/C++ applications as
well as some general info about how gcc works.
Cheers,
Radek.
