liboesenc_pi.so: undefined symbol: _ZTI23PlugInChartBaseExtended

[Arno]

Hi everybody,

since 2 weeks I try to compile OpenCPN and oesenc_pi from source under Ubuntu 32-bit.
The OpenCPN version 4.5.0 and all plugins which will be build with it run fine. But when I compile any version of the oesenc_pi from version 2.0 down to the first committed version I always get an error at load time:


undefined symbol: _ZTI23PlugInChartBaseExtended


Here is the extract from the logfile:

Any idea what is going wrong?

Why use an old version of OpenCPN. Probably to old.
Upgrade to latest stable version 4.8.4 and you'll be fine.
Thomas

[Arno]

Thanks for your answer.

Unfortunately this is not a solution. I compiled version 4.8.2 which is the newest available version in the git repository. This version results in incompatible plugins. Here an extract from the logfile:

Only version 4.5 compiles without any problems.

The missing symbol is due to an exported class in the oesenc plugin which will be dynamically loaded from OpenCPN. Therefore I think it depends not on the OpenCPN version, but I dont know why it is missing.

Arno...
Current oesenc plugin will not work with OpenCPN as old as 4.5. Build at least 4.8.4 and better invest your time into debugging why it is considered the plugins incompatible on your system, which does not happen on any of our testing machines. You may start looking at https://github.com/OpenCPN/OpenCPN/b...nager.cpp#L940

Pavel

[Arno]

Thanks for the advice.
I will try a new compilation on a different hardware platform...
Arno

[did-g]

Did you do
sudo make install
after compiling 4.8.2? From the errors it looks like you trying to run a newer opencpn with a previously installed older one.

[Arno]

Yes, I did a sudo make install and I also checked that there is no old installation at /usr/local...

By the way, opencpn will be installed to /usr/local and oesenc_pi will be installed to /usr if I use sudo make install. So I have the choice to change the prefix in the makefile of oescenc or to copy the installed folders by hand to put oesenc_pi in the right place.

Which Ubuntu version? Are you using libelf?

For oesenc, yes some plugins default to /usr rather than /usr/local/, you can use:
cmake -DCMAKE_INSTALL_PREFIX=/usr/local
for choosing where to install them
.

[Arno]

It's a 32-bit machine therefore it runs version 15.04. That is the reason why I will try to switch to another hardware (64-bit) with a newer Ubuntu version.

libelf is installed but not linked to opencpn as far as I can see.

Thanks for the remark on the prefix define...

In this case you should have

Did not found LibELF, plugin compatibility check will be simplified.

in cmake output and it could be a false positive.
If it's not installed try to install libelf dev
could be libelf-dev
or libelfg0-dev
actual name is distribution and version dependent.
If it' already there on your box with 15.04 I'm afraid you're on your own.

[Arno]

did-g thanks a lot!

libelf-dev was the key to the solution. This lib must be installed. Now opencpn 4.8.2 is running without any problems and also the oesenc_pi plugin is working.

Thanks again
Arno
