I have been trying to get my Arduino/Eclipse environment setup. For some reason I keep having trouble with the linker.
Here is the error I receive when trying to build.
So there is a conflict between libgcc and libc?
I have followed these instructions pretty close, but there are some nuances.

I realized that I did not add the libary m. So I appended -lm using the add libraries option.
The make file now has this command.
This still gave me the same issue.
Looking at the guide at http://arduino.cc/playground/Code/Eclipse
It says,
My make file now has this command.
