New versions of iasl have introduced improved C file generation, as reported in the changelog: iASL: Enhanced the -tc option (which creates an AML hex file in C, suitable for import into a firmware project): 1) Create a unique name for the table, to simplify use of multiple SSDTs. 2) Add a protection #ifdef in the file, similar to a .h header file. The net effect of that on generated files is: -unsigned char AmlCode[] = +#ifndef __SSDT_S4_HEX__ +#define __SSDT_S4_HEX__ + +unsigned char ssdt_s4_aml_code[] = The above example is from ssdt_s4.asl. Fix the build with newer versions of iasl by stripping the '_aml_code' suffix from the variable name on generated files.
