Eclipse(CDT)--manual make works but make from Eclipse doesn't

[thrash242]

I have a fairly simple C++ program that uses the windows port of PDCurses, which I built and installed correctly (as far as I know).

When I do a build (using make) from Eclipse, I get several errors, including that curses.h can't be found. However, when I run make from the project directory manually from a command prompt, everything works fine.

Any ideas why? I'm sure there's some setting I'm missing, but I don't get why running make from a command prompt works fine, but doing so from Eclipse doesn't. I'm using the same exact makefile.

The makefile is pretty standard and is based on the default one that Eclipse makes with a new project. I'm using MinGW and MSYS. I'm using Vista 64.

This problem isn't too major, since I can still build it fine, but I miss out on Eclipse showing me errors, since it *always* thinks there are errors that don't exist when I build manually.

Thanks in advance.
