Running on iOS

[pdoh...@cipherloc.net]

I am back again with an issue on iOS that only seems to be affecting devices and not the simulator.  I did not have access to a device until this point so it went unnoticed.  I can build the library with no compiler issues but when I try to run it on a device(this one is arm64 architecture) I get an error of unreferenced symbols on two functions out of the bench object file.  The functions are BenchmarkAll2(double,double) and GlobalRNG().  We are running with version 5.6.5 of cryptopp on xcode 8 in an objective c program.  Any ideas or possible a hint as to where we should look would be much appreciated.

I meant to put undefined symbols not unreferenced

It sounds like you are including test files in your library build. The library should *not* include:

* validate.h
* bench.h

* test.cpp
* bench1.cpp, bench2.cpp
* validat0.cpp validat1.cpp validat2.cpp validat3.cpp
* datatest.cpp
* regtest.cpp
* fipsalgt.cpp
* dlltest.cpp
 
I've been meaning to investigate moving them into a Test namespace (CryptoPP::Test). We've got a major change coming up for the next release, so now would be a good time to do it.

If interested in more of the details, GlobalRNG() is declared in validate.h, and it is defined in test.cpp. It is used by the validation and test routines. The output artifact for validation and test is cryptest.exe.

I'm not getting any hits after building the library for iOS and arm64:

hilbert:cryptopp$ nm libcryptopp.a | c++filt | grep GlobalRNG
hilbert:cryptopp$ nm libcryptopp.a | c++filt | grep BenchmarkAll2
hilbert:cryptopp$

Also, the 'make sources' recipe gives you lists of source files. It
does not list header files, though:

Apologies for replying so late.  Work got a bit busy.  I was able to solve this by removing bench.cpp from our folder for compiling.  It seems that it was left over after an update.
