ARM Compilers: refer external symbols from elf

HI guys,



is it possible to compile a source file where the external symbols should be referred in the elf (elf for whole build) by ARM compiler/Linker.

we use compilers :ADS120 ,RVCT3.1,RVCT4.1

Scenario :

Build consist of all the source, we make build by integrating  this source file/changes and we compile whole build. so if there is any compilation/link error with integrated source file/changes we will able to know after whole build is compiled .
i want to optimize this process,by compiling only changed files before integrating in the whole build ,where external symbols should be referred in elf (generated for whole build(previous  successful build)). Once it compiled successfully i can integrated in build and compile.so by this process i will be able to resolve the errors in very less time.

Thanks for reading the post.

    Once you have complied things to an executable no symbolic information is exported, so an ELF executable cannot be an input to a link step.

    You original question was around trying to avoid recompiling everything  if only a few files have changed - build tools like GNU Make will only rebuild what has changed, and reuse the old output objects if the file has not changed. I'd suggest investigating that type of Build tool - it does exactly what you are trying to do ...
