Hi, I cannot compile TI's MSP430F21x2 examples with mspgcc. It gives me following error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘void’
* Ubuntu 10.04 * I downloaded mspgcc4 binary from: http://sourceforge.net/projects/mspgcc4/files/GCC-4.4.2-GDB-7.0-20091124/20091124-msp430-gcc-4.4.2-gdb-7.0-insight-6.8.7z * I unpacked it and copied to /opt dir * Then I added following line to .bashrc file: export PATH="$PATH:/opt/msp430-gcc-4.4.2/bin" Actually I'm not sure if I'm using right mspgcc because I have also mspgcc-tinyos in my machine (http://docs.tinyos.net/index.php/Installing_TinyOS_2.1) maybe that might cause problems.

Is makefile OK? Is there something wrong with my mspgcc installation? Andres
