CDT for Windows - default install, "launch failed no binaries" [message #197694]

So I've installed CDT for Windows to take for a test drive before
we teach CDT and PTP at OSCON next week.
Great work Doug! No longer do we need to tell Windows folks to install
all of Cygwin, etc.

I did the default install on a machine without Eclipse or Cygwin.
I did everything using the defaults.
However when I create and build the 'hello world' C project I get
"Launch failed no binaries."

No binaries are under the Debug config.
When I change source and save i get in the Console view:
**** Build of configuration Debug for project ****
then nothing else except for
(Exec error:Launching failed)

I tried to force the build a couple of other ways too
(nice new little "hammer" action icon)
but no luck.

What's wrong?

I also had the warning "error launching external scanner info."
MinGW/bin wasn't in my windows path.
I added it and now i can gcc from the command line.
I launched Eclipse, no longer see the warning, but still
no binaries found.
I rebooted too.

There was no PATH variable in Project Properties, C/C++ Build,
Environment. Setting it (to MinGW\bin path) doesn't help

The Project Properties, C/C++ Build, Settings has Cygwin C Compiler and
Cygwin C Linker! Not MinGW!

The Toolchain editor (Project properties, C/C++ Build, Tool Chain
Editor) was set to Cygwin GCC. Changed to MinGW GCC.

It works now!

Why was the default set to Cygwin?

My question is rather: why does it compile a MinGW project with default
settings, but not a Cygwin project?

I'm also having a problem with cygwin. I've traced it to the class
IsGnuCygwinToolChainSupported. It is checking for {"gcc ", "binutils ",
"make "}; in c:\cygwin\etc\setup\installed.db. If it doesn't find any of
these cygwin is not supported. I checked installed.db on my machine and
there is no "gcc ". Perhaps the comparison should be for gcc-core.

BTW, I fixed Karen's bug for 4.0.1.

Because the MinGW project settings adds the mingw/bin directory to your
path.

In Wascana 0.9.3, if you don't have cygwin installed, it won't be
offered as a choice in the New Project wizard by default.

Hi, I'm new with Eclipse, I read this thread, but I couldn't get the tip to
compile a Cygwin console project under windows (XP, btw). I have makefile
errors working with Cygwin C++ compiler, so I have no the binaries.
I've tryed everything, but nothing seems to work. The cygwin folders (bin,
lib, etc are in the PATH environment variable).
I choose the correct toolchains, etc. What set value I've missed?

Thanks for any tip (sorry for my english)
greets, rossana
