Answer 1

How did you setup your Cygwin toolchain in your Eclipse CDT?
(from the Alex Wu's excellent blog post in Alex's Tech Blog)

1/ Install the Cygwin properly, you need following packages:

binutils
gcc
gcc-core
gcc-g++
gcc-mingw-core
gcc-mingw-g++
make
gdb (needed if you want to support debug in eclipse)

you can check your cygwin installation using the 'cygcheck -c' command

2/ Add %cygwin%\bin to your env PATH, then open the eclipse. you will find the cygwin tool chain will be shown when you open a new c/cpp project wizard.

3/ Configure the GDB.

Go to Windows->Preference->C/C++ -> Debug -> Common Source Lookup.
Add following 'Path mapping':

\cygdrive\c -> c:\
\cygdrive\d -> d:\ 
other drives if any .......

Answer 2

you need minGW 64 bits
