Problem with aarch64 #251

Closed mialuyao closed 1 year ago

mialuyao commented 2 years ago

I'm trying to compile relic library on Linux ubuntu 5.15.0-52-generic aarch64. When the compilation I received this error:

libscapi/build/OTExtensionEncrypto/extern/ENCRYPTO_utils/extern/relic/src/arch/relic_arch_x64.c:43:49: error: unknown register name ‘%rdx’ in ‘asm’
   43 | #define asm                                     __asm__ volatile

How to fix this problem? Thank you!

You should try changing the configuration to ARCH=A64 for aarch64 support.

I got what your mean. I'm ashamed that I'm a beginner in programming. I try to add SET(CMAKE_SYSTEM_PROCESSOR A64) in CMakelists.txt, which is invalid. And I have no idea how to change the configuration to ARCH=64. Besides, I got the warning as 

CMake Warning (dev) in extern/ENCRYPTO_utils/CMakeLists.txt:
  Policy CMP0111 is not set: An imported target missing its location property
  fails during generation.  Run "cmake --help-policy CMP0111" for policy
  details.  Use the cmake_policy command to set the policy and suppress this
  warning.

  IMPORTED_LOCATION not set for imported target "Boost::thread".
This warning is for project developers.  Use -Wno-dev to suppress it.

Is this warning related? Could you give me some instructions? Thank you very much!

Don't worry, RELIC's usability is nothing to write home about.

You should execute cmake -DARCH=A64 <build_dir> to set the target architecture to Aarch64 in your build directory. It should have been detected automatically, but Aarch64 support is recent and might still be buggy.

I assume problems were solved, so closing it for now.
