TODO:

Headline

2014 Aug. 12-13-14

Configuration imarsu * /etc/config/system * hostname: imarsu

  • mv openwrtexperiment openwrtexperiment20140812 * try latest openwrt version with openwrtexperiment buildroot
    • using uclibc
    • Using latest feeds.conf, enable oldpackages feed

Problem

  • ldso debug
    • uclibc ldso.c in builddir/toolchain-i386i486gcc-4.8-linarouClibc-0.9.33.2/uClibc-0.9.33.2/ldso/ldso/
    • vim builddir/toolchain-i386i486gcc-4.8-linarouClibc-0.9.33.2/uClibc-0.9.33.2/.config
      • DODEBUG? Search for DEBUG
    • SOLUTION: minimal build –> no problem
      • incremental packages selection.. add ima-carpc feed at the end and rebuld –> no problem!!!

Trick

  • Quick edit and recompile package libdaiutil ? procedure?:
    • edit code
      • make package/libdaiutil/clean V=s
      • make package/libdaiutil/{clean,compile} V=s

  • data pipe line segfault at add() lock_guard.
    • pipeline is a thread.
    • each module is a thread and starts writing to pipeline after started. Pipeline may not be started.
    • not working solution: start pipeline first
      • module stage is registered after module is created.
    • other solution: create modules, register pipeline stage, start pipeline, start modules.
