Title: Bitcoin core 0.9.2.1 on Centos 6.5
Post by: yabu on September 07, 2014, 08:21:31 AM
I'm trying to run the latest bitcoin core on my centos 6.5 server, but I get the following
symbol lookup error: .../bitcoin-0.9.2.1-linux/bin/64/bitcoin-qt: undefined symbol: _ZN10QTextCodec11validCodecsEv
 
What's missing?

Apparently qt 4.6.4, see here for bug report on git https://github.com/bitcoin/bitcoin/issues/4799

I hope this helps: https://github.com/bitcoin/bitcoin/issues/4799

CentOS ships qt 4.6.2. Our version (4.6.4) makes use of codecForTr which calls the newly defined (in 4.6.4) validCodecs. Annoying. Would be solved by building against 4.6.2 instead.

I think we have to draw the line somewhere, though, we can't keep downgrading Qt in the releases. If you build from source it will work on your platform.

Centos 7 has been out for a while which uses Qt 4.8.5.

I hope they would put together a bitcoin core client for RHEL/Centos 6.x because it's going to be around for a long time. EOL is currently set at 2021.

It says if you build from source it will be fine. Have you tried it?

Thanks for the link.

Tried to build bitcoin core on my centos 6.5, but haven't been able so far to sort out the dependencies.
Also, haven't found any centos specific instruction for compiling. Are there any?

Not on github, I don't think.

CentOS pops up every so often: https://bitcointalk.org/index.php?topic=588032  A more in-depth search might yield more.

Thanks for the link.

But I think I'll stick to running an older version of bitcoin core for now.
