hi hi hi,

I am trying to get the vinylcontrol~ external to work on my raspberry pi. I have eventually seemed to be able to compile it but when I run a patch with the vinylcontrol~ external in it I get the following error :

error: /usr/lib/pd/extra/vinylcontrol~.pd_linux: /usr/lib/pd/extra/vinylcontrol~.pd_linux: undefined symbol: _ZN16flext_root_multidlEPv

I'm a complete noob when it comes to compiling, and I have struggled to get the flext build system working. It seems to build a couple different vinylcontrol~.pd_linux externals in folders marked shared, single and multi. I have tried them all and none work.

Thanks in advance. Any and all help is much appreciated.

@suroh It looks like you are missing flext, or it is not found.
More help here with flext...... http://frauzufall.de/en/2014/linux-vinyl-control-puredata/
But depending on your system and Pd version you might need to delve deeper for a 64-bit compilation of flext........ https://grrrr.org/pipermail/flext/2014-July/000481.html.... with a possible solution in the next message........https://grrrr.org/pipermail/flext/2014-July/000482.html

Hi David, thanks for the speedy reply. I do have flext installed, previously my error was that it couldn't find libflext.so.0.0.6 which I managed to fix by changing my flext install location to /usr/lib/ but now I have the error mentioned in my first post...

Thanks for the additional links, I'll try out that possible solution you found for 64-bit compilation.

David, thank you! You have made my day! I have managed to get it working by adding the flags found in the posts you found.

@suroh Brilliant! Well done.
And thank you for letting us all know. Someone will stumble on your thread one day and have confidence they will also succeed.
(adding -DFLEXT_USE_CMEM=1 and -fPIC was the solution!) from pipermail.
David.
