Hi. We are using IRIS motes and we would like to convert the value provided by the temperature sensor. The formula given by the datasheet requires logarithm, so we need the math.h header file in the folder /usr/msp430/include/math.h. But we are having trouble when we want to include it. During the compilation it prints strange errors for math.h, here is a sample: /opt/tinyos-2.1.1/tos/lib/net/blip/math.h:22: syntax error before `}' /opt/tinyos-2.1.1/tos/lib/net/blip/math.h:27: syntax error before `const' /opt/tinyos-2.1.1/tos/lib/net/blip/math.h:36: syntax error before `_PARAMS' /opt/tinyos-2.1.1/tos/lib/net/blip/math.h:37: syntax error before `_PARAMS' /opt/tinyos-2.1.1/tos/lib/net/blip/math.h:38: syntax error before `_PARAMS'
And there is errors like for almost all the lines of math.h. And of course the log function we want to use is not recognized. We tried to include the header like any header: #include <math.h> but it's not the one we want because the log() function was not recignized. So we tried to put the complete path like this: #include "/usr/msp430/include/math.h" and then the errors occured. Is it a classpath error or something like that? Thanks in advance. Etienne Lachaud.
