Title: Error compiling on raspberry pi 2 with salsa20.s.
Post by: zhangweis on March 14, 2015, 12:04:30 am

I tried gcc and clang with the similiar errors like below. I guess it's because salsa20.s doesn't support arm. What is this salsa20 for and can I make it work with arm? Can we turn it into C to make it compile or is there a way to bypass this?

Seems solved by commenting all the salsa related lines in libraries/fc/CMakeLists.txt

I also want to mention that I have to use export LC_ALL="en_GB.UTF-8" instead of en_US as I don't have locale en_US preinstalled on my raspbian.

I'm also getting this error early on:
In file included from /home/pi/graphene/graphene/libraries/fc/vendor/secp256k1-zkp/src/secp256k1.c:11:0:
/home/pi/graphene/graphene/libraries/fc/vendor/secp256k1-zkp/src/util.h:102:37: error: ‘__int128’ is not supported for this target
 SECP256K1_GNUC_EXT typedef unsigned __int128 uint128_t;

which, according to:
http://raspberrypi.stackexchange.com/questions/3919/using-128bit-integers-in-gcc
__int128 isn't defined on raspberry pi

I think you can just comment out:

Code: [Select]

#SET(SALSA_SRC vendor/salsa20/salsa20.s)and it will work. It's already checking if it is not apple, it should also check if it is not x86 or x86_64

Recently removed salsa20 from build; should be gone in upcoming versions: https://github.com/bitshares/bitshares/issues/1089#issuecomment-114653757
