I’ve managed to compile the the SDK fine in Linux and I can load the example in Reaper just fine. Now I’d like to figure out how to set things up to compile my own plugins. What should my folder structure look like? Something like this?
My_Root_Dir
-vst3sdk
-MyPlugins
-build
-CMakeLists.txt
Also, I’m not sure what should be in CMakeLists.txt, I’ve got the following:
cmake_minimum_required (VERSION 3.19)
project(MYPLUG)
add_subdirectory(vst3sdk)
I’ve added some defines to the top level CMakeLists.txt file and it’s making some progress.
cmake_minimum_required (VERSION 3.19)
project(MYPLUG)
add_definitions(-D_DEBUG -DDEVELOPMENT)
add_subdirectory(vst3sdk)
However, it ultimately fails with errors:
source/vst/hosting/module_linux.cpp.o
[ 80%] Linking CXX executable /VST3Inspector/VST3Inspector
Error creating directory "/VST3Inspector/Resources".
make[2]: *** [vst3sdk/public.sdk/samples/vst-hosting/inspectorapp/CMakeFiles/VST3Inspector.dir/build.make:219: /VST3Inspector/VST3Inspector] Error 1

make: *** [Makefile:91: all] Error 2
Looks like it’s trying create a directory off the root of my harddrive. The result of a missing define I suspect. Not sure where to look.

So I gave up on trying to compile my plugin outside of the SDK and opted to just replace the contents of AGain with my own code and modify the CMakeLists.txt file accordingly.
Compiling seems to go fine, but there’s an issue during linking.

I had forgotten to include my entry.cpp in the CMakeLists.txt.
