converting Keil MDK-lite to OSX GNU problem.

benevbright

because license is so expensive, I'm converting my project to OSX GNU

I'm solving problems step by step..

Anyone can help me what's wrong here?

Thanks.

    Hi, to solve undefined reference to `sqrt' your need to link with the -lm option. The placement of this option is important (see gcc reference) and should be just before the -o option. As an example, see this modified MAKEFILE section:

    nrf51422_xxac_s110: $(BUILD_DIRECTORIES) $(OBJECTS) @echo Linking target: $(OUTPUT_FILENAME).out $(NO_ECHO)$(CC) $(LDFLAGS) $(OBJECTS) $(LIBS) -lm -o $(OUTPUT_BINARY_DIRECTORY)/$(OUTPUT_FILENAME).out
