compiling software for embedded linux distro (openwrt)

Question

I have a problem with Linux embedded OpenWRT. I must compile a software for arch MIPS. The software is composed of 2 file.c and 4 /include/file.h ... I have compiled a toolchain for Openwrt with the "new" gcc (for mips) I have compiled one by one the 2 file.c getting 2 file.o as output. How can I create a unique binary file to execute the software?

Second question: it is correct to compile the file one by one?

Thanks, I hope that my question is clear.

You can create an OpenWrt package. See this tutorial. You can point OpenWrt to the folder, where your files are and let compile the project there instead of pulling it from a VCS repo.

See this SO answer about compiling multiple files with GCC.
