Ubuntu 14.04 compatibily
smvicente opened this issue · comments
Hi guys!
Even though I have installed an updated GCC version from the one available for Ubuntu 14.04.5 using the PPA ubuntu-toolchain-r/test, I'm still getting this error:
dlopen(/opt/ida-6.95/plugins/labeless_ida_690.plx): /opt/ida-6.95/plugins/labeless_ida_690.plx: symbol _ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE9_M_createERjj, version GLIBCXX_3.4.21 not defined in file libstdc++.so.6 with link time reference
I guess this is compilation/ABI-related, so not sure if there is an easy solution for this besides me upgrading to a newer Linux distro?
Thank you in advance.
Best.
Hi @smvicente,
Yes, it looks like ABI problem. You can build the labeless. I'll help you providing the instructions.
First of all, could you shown me the output of ldd /opt/ida-6.95/plugins/labeless_ida_690.plx?
Hi @a1ext!
Thank you for your swift response! The output is:

Hmm...
I found this similar issue, so we can try to rebuild Labeless with CFLAGS="-D_GLIBCXX_USE_CXX11_ABI=0"
I'll try in few days and let you know.
Nice! thank you!!
Hey @smvicente,
Did the Labeless work before the gcc update?
I need do few more checks, could you send me the output of the following commands:
ldd -r /opt/ida-6.95/plugins/labeless_ida_690.plx
ldd -r /opt/ida-6.95/libprotobuf.so.9
Need to determine if protobuf requires rebuild too.
Hi @a1ext!
No, Labeless didn't work before the GCC update. In fact, that was the reason for me to update it :)
Find attached the output of those commands: output.txt
Thanks a lot!!
Hey @smvicente,
Could you try this build labeless_1.1.2.1_linux_gcc_abi_fix0.zip
Hey @a1ext!
I can confirm it works! thank you so much!!
You welcome :) Thanks for reporting a bug. Feel free to request new features and report bugs.
Hi!
Sorry for writing again here... It turns out that I had to downgrade to the official Ubuntu 14.04.5 GCC version so I can continue updating the Kernel to recent revisions... I was having problems with my custom one otherwise.
I'm leaving here the output of previous commands: labeless_output.txt
This is just in case something quick can be done, but if it takes more than 10 minutes then don't worry because I think I'll upgrade my system at some point in the near future so this should not be a problem anymore :)
Thank you!!
Hi,
hmmm... problem in glibc ABI, as before. Don't think it could be solved quickly
Then don't worry, not important! I'll upgrade in some months so I can wait as I don't need Labeless everyday, although useful :)
Appreciate the response!
Best.
As a solution, you could build it on your own, I'll post here instructions how to do this a bit later
Ok great!!
