First, it is improper ettiquite in this list to post messages in anything but plain text.
At first glance, it looks to me like you are missing the "main" function. As for the IRQ declaration you listed, there is nothing wrong with it. After declaring two variables, it compiled for me fine, but not without a "main" function. Not sure if the requirement for including a main() function is in the documentation or not, but it is a general requirement for all C programs. The docs do talk about the possibly of calling some other function from the startup code (auto-generated by the compiler to get things going), but the default is to call main().

I read the GCC help and think that I changed the code correctly, but the error is still there. Here's the code: interrupt (UART1TX_VECTOR) usart1_tx(void) { char next; switch (chars_left) { case -1: //Writing null-terminated string next = *(++tx_buffer); if (next != 0) { TXBUF1 = next; } else { chars_left = 0; } break; case 0: //Nothing left to write break; default: //Writing fixed length data next = *(++tx_buffer); TXBUF1 = next; chars_left--; break; } return; } and the error that I get is "C:/mspgcc/bin/../lib/gcc-lib/msp430/3.2.3/msp2/libgcc.a(_reset_vector__ .o)(.init+0x38): In function '_reset_vector__':: undefined reference to 'main' Anyone know what this error means?
