Hello, I've figured out how to use the JIT example script "TccSimpleLP.js" (which exists in /HISE-1.0.0/tools/scripts ) after checking the source codes.
Download the build version 646. (windows)
Replace "TccLibrary.h" (which exists in /HISE-1.0.0/tools/tcc/windows/include) by the file "TccLibrary.h" (which exists in /HISE-1.0.0/hi_scripting/scripting/api)
Make the folder named "tcc" in C:\Users\your\AppData\Roaming\Hart Instruments & move all the contents (which exist in the source /HISE-1.0.0/tools/tcc/windows) to that folder.
That's it!! I wish this JIT functionality would be revived...
Thanks for giving HISE
