 | | main() not defined?

I get this error - "main() not defined" - when compiling. The code is copied straight from the Ferrari book. While C is the language of my choice, the line of code isn't so obtuse as to hide errors from me. So probably there is some other requisite (...) (22 years ago, 20-May-02, to lugnet.robotics.rcx.nqc)

I believe any data source (not just timers/sensors/variables) can be used in SetUserDisplay. The big limitation is that local variables cannot be used since the display is updated in a global context independent of the tasks. If you know of data (...)

Oops. Looks like a bug in the NQC API file. I just fixed the bug in the NQC source, but it's not major enough to warrant a new release yet. In the meantime, you can add the following lines to the top of of your source file as a work-around: #undef (...) (22 years ago, 8-May-02, to lugnet.robotics.rcx.nqc)

SetUserDisplay does not work like that. You need to specify either a sensor, timer, or global variable. Once you have done that it will continuously update the display as the value changes. In your case you should write your program something like: (...) (22 years ago, 6-May-02, to lugnet.robotics.rcx.nqc)

The following code always displays 0 regardless of the program slot in which it is run. Is this a bug, or do I not understand the purpose of Program()? I'm using the 2.0 firmware and NQC 2.4 r2. task main() { SetUserDisplay(Program(),0); (...) (22 years ago, 6-May-02, to lugnet.robotics.rcx.nqc)

The only thing I could think of is if NQC thinks you are generating code for some other device (e.g. CyberMaster). Try adding -Trcx2 to the command line to force NQC to target RCX2. If that doesn't fix it, email me the program and I'll take a look. (...) (22 years ago, 7-Apr-02, to lugnet.robotics.rcx.nqc)
