Yesterday I built trb on my local computer running CentOS 6.9. I imagine I saved a bit of time from already having keccak V setup. The only dependency from the list on the bitcoin foundation's website I was missing was "bc."1
After grabbing the vpatches from the foundation's website I also pulled in two other vpatches written by jfw, one that provides an improved way to get/send rawtx's and another that fixes up the bitcoind build process in various ways. The commands to grab the patches and seals:
wget http://fixpoint.welshcomputing.com/v/bitcoin/bitcoin_rawtx_get_send.vpatch
wget http://fixpoint.welshcomputing.com/v/bitcoin/bitcoin_system_compiler.vpatch
wget http://fixpoint.welshcomputing.com/v/bitcoin/bitcoin_rawtx_get_send.vpatch.jfw.sig
wget http://fixpoint.welshcomputing.com/v/bitcoin/bitcoin_system_compiler.vpatch.jfw.sig
After a successful press, I ran into a couple of errors when trying to build the beast that is trb. The first one was some error related to my LD_LIBRARY_PATH variable. (UPDATE: As jfw pointed out in the comments, this error was received when I tried to do the build for the first time, without his system_compiler patch.)
You seem to have the current working directory in your
LD_LIBRARY_PATH environment variable. This doesn't work.
make[2]: *** [core-dependencies] Error 1
make[2]: Leaving directory `/home/whaack/v/trb054/bitcoin/build/buildroot-2015.05'
make[1]: *** [buildroot-2015.05] Error 2
make[1]: Leaving directory `/home/whaack/v/trb054/bitcoin/build'
make: *** [build] Error 2
I updated my environment by running:
LD_LIBRARY_PATH="";in my terminal.
The next problem I ran into was building Boost. I caught the issue because I actually stared at the screen and watched all that compiler spew. Python errors flowed in front of my eyes, and I figured that the problem must be related to the fact that the native python on CentOS 6.9 is python 2.6.6 rather than python 2.7.x.
Getting my environment to use python 2.7.x instead of python 2.6.6 was a little bit tricky. Apparently you cannot update the native python without putting your OS in danger. So you need to install this program scl as well as python27 through yum and then use scl to start a temporary environment that has python pointed at python27. In this environment you build bitcoind.
scl enable python27 bash
cd ~/v/trb054/bitcoin/
make ONLINE=1
- I also had to downgrade my gpg from 2.X to 1.4.23, as well as tweak my path so that my gcc was 4.4.7. (Previously my gcc was pointed to some gcc 8.x used by a 2019 version of GNAT.) [↩]
