 | | Warning cleanup questions with gcc3.2

When compiling brickos with gcc3.2, I get a lot (about 360 or so) of warnings about two things; a) warning: multi-line string literals are deprecated These seem to be mostly quotes around blocks of assembly code. Some of the code in lib/mint seems (...) (22 years ago, 5-Sep-02, to lugnet.robotics.rcx.legos)

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)

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)

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)

Have you considered implementing thread cleanup handlers? Similar to what pthread_cleanup_push and pthread_cleanup_pop provide.

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)

(...) yes, that's possible, but isn't the symbolsrec format a bit of a standard, indicating that the 2.12.1 version is just buggy? Also, it doesn't help with 2.13 since that one doesn't even get to produce any code. alejandro (22 years ago, 2-Sep-02, to lugnet.robotics.rcx.legos)
