Ubuntu make shared object error

linux
#1

I created a of project in Windows using VS 2015 and was able to run it through the IDE. I wanted to build it and test it on Linux (Ubuntu) using this CMake addon.

I downloaded the OF Linux libraries and was able to generate the makefile using the addon. However, when I use that makefile the compilation fails with below error.

[ 95%] Linking CXX shared library ../bin/A01P01.app/Contents/Frameworks/libopenFrameworks.so

Does this mean I need to recompile the POCO sources with the -fPIC option?

#2

I’m having similar problem linking poco “relocation … again symbol” fails.
How can we recompile with -fPIC ?

#3

the install_dependencies.sh script should recompile poco with the correct settings, have you updated ubuntu recently or something like that?

#4

yes #!@ running now Ubuntu 16.10
I recompiled successfully via ‘install_dependencies.sh’ but compiling my app still fails.
I also tried ‘./apothecary update poco’ without success :frowning:

#5

can you try if the gcc6 version of the nightly builds works for you?
