1) If you start a "normal" ((ie cmd.exe) not cygwin command prompt, are
you able to run make ok?
[zhao]yes, I can make by cmd.exe and run the built application which is
the usually ways I do now
2) If so, is it definitely the make you expect, ie a GNU make?
[zhao] yes, it is definitely a GNU make. however I need to specify a
detail compiler, like g++-3,g++-4,gcc-3
3) Still if so, Try running cmd.exe from within Eclipse, that should
inherit the environment that Eclipse is running as and perform the same
tests as above.
[zhao]Where do you configure cmd.exe in Eclipse to run it. I used to do
that from properties of project, but failed calling cmd.exe.
I double checked my eclipse version which only support CDT4 and I don't
want to upgrade eclipse.
