Ok, my application that I am porting has multiple directories and multiple sub-directories with multiple arches.

I have compiled one arch x86_64 on glibc which I compiled from the naclports

My next step is to take this simple app example provided by google.

----------------------------------------------------------------

Add the PNaCl toolchain to your path for convenience, if desired:

PATH=${PATH}:toolchain/linux_x86/pnacl_newlib/bin # Adjust the name for your system

Now compile hello.c:

pnacl-clang hello.c -o hello.nonfinal.pexe

pnacl-finalize hello.nonfinal.pexe -o hello.pexe

(NOTE: If you get an error about missing crt1.o or -lnacl, you must run the SDK install step. See the installation instructions in the previous section.)

You have now produced a "pexe", a PNaCl bitcode application. To run this pexe, it must be first translated to native code. Let's translate it to X86-32, X86-64 and ARM.

pnacl-translate -arch x86-32 hello.pexe -o hello_x86_32.nexe

pnacl-translate -arch x86-64 hello.pexe -o hello_x86_64.nexe

pnacl-translate -arch arm hello.pexe -o hello_arm.nexe

and apply it to this (which is the output of my complile with compat-glibc x86_64?

**********Thanks in advance**************

*************UPDATE************

Looks like the solution to getting from a large application to NaCl or PNACL involves following cross compile directions and using CMake or AutoConfig.
