combine two GCC compiled .o object files into a third .o file

People also ask

How do I merge object files?

select the "Object" folder and click the objects you would like to append/link to your project. Several objects can be selected by SHIFT+RIGHT click on them. Appending is merging the object into your current blend file and active scene/layer. By linking, the object is not copied but linked to the original .

Who merges 2 or more object files into one?

In computing, a linker or link editor is a computer system program that takes one or more object files (generated by a compiler or an assembler) and combines them into a single executable file, library file, or another "object" file.

Are .O files cross platform?

No. They are not platform independent.


Passing -relocatable or -r to ld will create an object that is suitable as input of ld.

$ ld -relocatable a.o b.o -o c.o
$ gcc c.o other.o -o executable
$ ./executable

The generated file is of the same type as the original .o files.

$ file a.o
a.o: ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped
$ file c.o
c.o: ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped

If you want to create an archive of two or more .o files (i.e.. a static library) use the ar command:

ar rvs mylib.a file1.o file2.o
