build errors

Inside /bts_wallet/CMakeLists.txt (or whichever app you are building), you need to add pthread as an argument to target_link_libraries().

I followed the build instructions.

When I run: make

I get:

../vendor/leveldb-1.12.0/libleveldb.a(port_posix.cc.o): In function `leveldb::port::InitOnce(int*, void (*)())':
/home/tzadik/BitShares/vendor/leveldb-1.12.0/port/port_posix.cc:50: undefined reference to `pthread_once'
