[Help needed] 'make' throws 'Type mismatch' error

[rcksn]

Hi, I generated the makefiles using .../build> cmake .. -G "Eclipse CDT4 - MinGW Makefiles" but when I tried to do the next step .../build> make the following error occurred:

'make' has been successful with Ferror and another library (nlopt), so this error seems to occur only for this project.

Any help would be appreciated.
