Hi, I was trying to write a toy luajit, use the libgccjit. and I want to call my defined functon from the jit code. not the libc function like printf or getchar. but it failed with error: undefined reference to `wrap_return_var' collect2.exe: error: ld returned 1 exit status libgccjit.so: error: error invoking gcc driver I checked my code, it seems ok, and if I change the name to printf, it compile success. so I wonder maybe the gccjit could not call user defined function? thanks.
