  Re: gcc
 
I am running Windows XP. Should I also use the version of binutils that the install steps recommend? I was reading the post about newer version of binutils and was wondering if there are any advantages to using the newer releases. If there are (...)

  Re: gcc
 
Sam Paolo Masetti instructions, (URL) suggest downloading gcc-2.95.2 for building the cross compiler. These instructions are standard instructions for windows os.

  Re: Help with Clock
 
(...) That's currently done in the leJOS loader (see rcx_impl/main.c), and only if no program is running. So you can't turn it off, but you don't need to turn it off either once your program is running ... Jürgen (22 years ago, 5-Sep-02, to lugnet.robotics.rcx.java)
 
  Re: Semaphore(s) locked when task killed.
 
This has been suggested and may very well be the best way to handle manual removal of a runaway task. I plan to investigate this once I get my current updates squared-away. I hope this type of handling can be done in the kernel only. User tasks (...) (22 years ago, 5-Sep-02, to lugnet.robotics.rcx.legos)
 
  Re: Semaphore(s) locked when task killed.
 
Last night I worked on a solution to this. So far it is coming along very good. My proposed solution is to write tasks so that they shutdown when signalled. The user tasks should respond to the run/stop button by shutting down gracefully. If a task (...) (22 years ago, 5-Sep-02, to lugnet.robotics.rcx.legos)
 
  gcc
 
Hi Everyone, I just installed the latest version of cygwin, and downloaded binutils 2.12. I am wondering what version of gcc I should download, thanks. Sam (22 years ago, 5-Sep-02, to lugnet.robotics.rcx.legos)
 
  Re: Help with Clock
 
What about turning the timer off that turns the RCX power off. What would be the class and method or is it a ROM routine. Thanks, Scott (22 years ago, 4-Sep-02, to lugnet.robotics.rcx.java)
 
  Re: Semaphore(s) locked when task killed.
 
Have you considered implementing thread cleanup handlers? Similar to what pthread_cleanup_push and pthread_cleanup_pop provide.

  Re: Semaphore(s) locked when task killed.
 
(...) hmmm I wonder what other unix like OSs do in this situation? automatically unlocking doesn't seem particuarlly clean, what is to say that it is safe to unlock the mutexes just because the locking thread has been killed? Perhaps we can (...) (22 years ago, 4-Sep-02, to lugnet.robotics.rcx.legos)
 
  Semaphore(s) locked when task killed.
 
I have found that killing a task which is sending data via lnp will cause lnp to stop functioning. Turning the brick off then on again will get lnp working again. The issue is with the semaphore(s) used in the kernel tasks. Currently there is no (...) (22 years ago, 4-Sep-02, to lugnet.robotics.rcx.legos)

John, Good Job, John! It seems that older version of gcc don't catch the problem.

  Small problem compiling w/gcc-3.2 and binutils-2.12.0 with patch.
 
While compiling the brickos kernel under gcc-3.2 and binutils-2.12.0 I was getting errors about nb_tasks and nb_system_tasks not being te same as their declarations so I made them volatile just like in the header and the kernel now compiles.
