Compiling a C++ program with g++

Question

I am having issues compiling my C++ program on g++ on Windows. My program is comprised of of the following files: one cpp file, two header files, and an asm file in MASM format. I tried using the following command to compile the x64 PE file:

g++ test.asm test.cpp -o test.exe

I am getting the following exception: file format not recognized; treating as linker script.

Could someone point me in the right direction? Thanks in advance!

There are different dialects of assembler. MSVC uses MASM while GCC uses GAS.

If your .asm file's format isn't understood by GCC try a different assembler like JWasm, UASM, SASM or NASM to compile it to COFF object file (e.g. jwasm -coff -win64 test.asm -Fo test.o) and then use GCC to link your C++ program with it.
