mingw linker cannot find library [message #209945]

Hi folks,
I'm an experienced user under an ARC context, but I'm setting up with
mingw for home use. I've posted on the beginner site as well.

using:
Eclipse Version: 3.3.1.1
CDT 4.0.2
GNU C++ version 3.4.5 (mingw special) (mingw32)

I built the stock Hello World with no problems and added a second
"utilities" static library project for practice. I did the following:
* checked "utilities" as a project reference for Hello World.
* added libutilities as as a lbrary to "Hello World" project library list.
* added "${workspace_loc:/utilities/Debug}" as the dir path for libs.
(libutilities.a lives there). (also tried the "file system" version of
this.
* Clean and build results in the following error:

g++ -LC:\projects\fargo\utilities\Debug -ohello_world.exe
src\hello_world.o src\c_template_class.o -llibutilities
C:\mingw\bin\..\lib\gcc\mingw32\3.4.5\..\..\..\..\mingw32\bi n\ld.exe:
cannot find -llibutilities
collect2: ld returned 1 exit status

Seems pretty basic - hoping it's just some idiot setup thing I'm doing.
Any ideas much appreciated.

Regards,
Steve

There's a beginner site? Where would I find that?

Tx,

To link a library libutilities.a, the command line option should be
-lutilities.

Hello Anton,
Yes, that was it - silly me...

I changed from "libutilities" to "utilities" in the "Hello World" project
library list and all is well.

Vielen Dank!
Steve
