Hi Leonid,
2016-01-16 11:13 GMT+02:00 Leonid Lisovskiy <lly.dev(a)gmail.com>om>:
Please check presence of full line information in
debug sections:
readelf -WS /opt/lib/openjdk8/arm/libnet.so | grep .debug_macinfo
It's not there, indeed:
[root@unknown root]$ readelf -WS
/opt/lib/openjdk8/arm/libnet.so | grep .debug_macinfo
[root@unknown root]$
Have you tried addr2line method?
No, but seeing full line information isn't there, it seems there's no sense
too.
Which gcc version you are using? Could it be
optimization issues? Will
something changed if build OpenJDK without compiler optimizations, gcc
flag "-O0" (disable -Os/-O2) ?
I'm using gcc-5.2.0. I haven't tried "-O0" flag, and I remember I used
to debug some applications with "-O2" built with the same toolchain
and '-g' flag, and they had line information. I've now noticed I have
"--disable-debug-symbols" and "--disable-zip-debug-info" in OpenJDK
configure options, maybe it's filtering out the '-g3' option I added
manually? I should try to disable those options.
Best regards,
Alex
