Problem using Aquila

[waterzch]

I compile Aquila step by step as the guide (installation-guides/install-aquila.md) said. But when I use it in QT project, it failed to compile.
Aquila/lib//libAquila.a(SignalSource.cpp.o): relocation R_X86_64_32 against `_ZTVN6Aquila12SignalSourceE' can not be used when making a shared object; recompile with -fPIC
Is it an issue?
How could I fix it?

You can't just link a static library (libAquila.a) into a shared object unless it's specifically prepared for that use case, see this SO question. To not meddle with the source code of Aquila, instruct CMake to build a shared library instead: cmake .. -DBUILD_SHARED_LIBS=ON. You should see a libAquila.so in your build folder.

If that fails, add the following after these lines:

set_target_properties(Aquila PROPERTIES POSITION_INDEPENDENT_CODE ON)

Successfully tested on a custom shared library that links to libAquila.so. Closing with dd2938d.
