Im trying to build Botan-1.10.12 for iOS (arch arm64) with Xcode 7.3.1. I tried to follow the guidelines on Botan's website: https://github.com/randombit/botan/blob/master/doc/manual/building.rst#for-ios-using-xcode
With some changes, I managed to build for armv7 doing the following:
./configure.py --prefix="armv7" --cpu=armv7 --with-zlib --cc=clang --cc-bin="clang++ -arch armv7"
sudo xcrun --sdk iphoneos make install
But when I try to do the same for arm64:
./configure.py --prefix="arm64" --cpu=arm64 --with-zlib --cc=clang --cc-bin="clang++ -arch arm64"
I get the following error:
ERROR: Unknown or unidentifiable processor "arm64"
And I get the same error if I try to change arm64 to armv8-a like the guidelines suggest:
ERROR: Unknown or unidentifiable processor "armv8-a"
I alse tried with --cpu=arm:
configure.py --prefix="arm64" --cpu=arm --with-zlib --cc=clang --cc-bin="clang++ -arch arm64"
and that works for the configure step, but then when I run sudo xcrun --sdk iphoneos make install, I get the following error:
In file included from src/asn1/asn1_alt.cpp:16:
In file included from build/include/botan/loadstor.h:13:
build/include/botan/bswap.h:58:11: error: unknown register name 'r3' in asm
: "r3", "cc");
^
1 error generated.
make: *** [build/lib/asn1_asn1_alt.o] Error 1
Im not that familiar with building stuff for iOS. How can I build Botan for arm64 iOS?
Thanks!
