Fix Version: 7.0.0.3
Severity: Standard
Applicable for: Wind River Linux 7
Component/s: Analysis
Trying to run Wind River Workbench 4 on an Emerson MATXM target under heapscope control displays an error in Workbench:
ERROR: ld.so: object '/usr/lib64/libheapscope.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS64): ignored
Workbench still seems to run OK; it still runs in 64-bit mode so the error seems to be non-fatal.
But I noticed that trying to run Workbench in 32-bit mode fails (and heapscope also complains about missing multilib versions). This is a problem because some processes launched by Workbench are 32-bit processes and I would like to get these instrumented by heapscope too. How can I make heapscope multilib aware ?
1. Configure:
/installations/wrlinux/7.0/LB21_7.0/wrlinux-7/wrlinux/configure --enable-reconfig --enable-board=intel-x86-64 --enable-rootfs=glibc-std-sato+debug-wb+gdbserver+analysis+lttng2+usttrace_demo+valgrind+kernel-debug+self-hosted --enable-kernel=standard --enable-build=profiling --enable-debuginfo-split=yes --with-layer=examples/lemon_layer --with-package=heapscope,cmake,qt4-embedded --enable-prserver=128.224.198.50:31721 --with-ro-sstate-mirror=http://szg-bld-wb.wrs.com/wrlinux-reference-builds/7.0/LB21_7.0/sstate
2. Boot it on Emerson MATXM
export DISPLAY=:0
x11vnc -forever -shared > x11vnc.log 2>&1 &
matchbox-terminal &
3. Connect VNC, and in the terminal:
zip up an already installed Workbench 4, copy to target
cd /root/wb4/workbench4/eclipse/x86_64-linux2
4. heapscope -- $PWD/wrwb
