...alling convention (the default > in C) are decorated with an underscore prefix. So you'd need to update > your nasm source file to define the symbol _Foo instead of Foo. (Most > assembly files use some sort of macro for wrapping this detail.) Yes, my assembly files do use prefix macro (ASM_PFX) for wrapping the underscore. We use the __USER_LABEL_PREFIX__ to control the prefix macro expand to be "_" as below. I find the __USER_LABEL_PREFIX__ has been predefined by clang-cl, but it is defined as nothing. That is why my prefix macro expands to be nothing. Do you know why the cla...

Below is an example to show my problem in linux. The example has two only source files: main.c and foo.nasm. $ cat main.c void Foo (void);
