Here is a patch to make buliding for ios a lot easier out of the box.
The patch:
1. Makes building cryptopp into a 'build' directory possible. In other
words, mkdir build; cd build; make -f ../GNUMakefile will put all the .o
and .a into the build directory. This is needed because iOS needs to run
the make process twice, once for the device and once for the simulator.
2. Adds a new target for iphone/libcryptopp.a, which uses (1) to build
the library
3. Adds a new target for iphonesim/libcryptopp.a, which uses (1) to
build the library
4. Adds a new target for ios/libcryptopp.a, which depends on (2) and (3)
and uses lipo to combine the two libraries
5. Adds a new convenience target, ios, which depends on ios/libcryptopp.a
Of course I'd like to see this patch reviewed and committed :-) So any
comments would be welcome.
Thanks,
Joseph
