| + | ===== Alternative option using asm ===== | ||
| + | |||
| + | User ColaEuphoria points out that an alternative for x86 architecture is to use assembly | ||
| + | |||
| + | section .rodata | ||
| + | |||
| + | global _my_data; | ||
| + | |||
| + | _my_data: incbin "my_data.file" | ||
| + | _my_data_size: dd $-_my_data | ||
| + | |||
| + | and compile it with `''nasm -felf64 resource.s -o resource.o''` (Note that ''-felf64'' here is Linux 64bit. The options needs to be replaced with the corresponding target architecture and OS). | ||
| + | |||
| + | The data can then be referenced using | ||
| + | |||
| + | extern const unsigned char _my_data[]; | ||
| + | |||
| + | with gcc. MSVC does not need the leading underscore in c-code and one can reference it using ''my_data''. | ||
