Does anyone know how to address the rpcserver.cpp error during the make process?

I am using Ubuntu 16.04 with the default boost 1.58.

System information Ubuntu 16.04, default boost 1.58 installed.

<!-- What version of Bitcoin Core are you using, where did you get it (website, self-compiled, etc)? -->

<!-- What type of machine are you observing the error on (OS/CPU and disk type)? -->

<!-- GUI-related issue? What is your operating system and its version? If Linux, what is your desktop environment and graphical shell? -->

The minimum required Boost is 1.64.0 since v22.0. To build Bitcoin Core on your system try to build with depends.

Thanks. I have removed the Boost 1.58 and manually installed by Ubuntu 16.04 with Boost 1.77.

Now, I have a new error with the main.cpp during make. Does anyone know how to address this main.cpp issue?

main.cpp: In function ‘void RegisterWallet(CWalletInterface*)’:
main.cpp:152:98: error: ‘_1’ was not declared in this scope
     g_signals.SyncTransaction.connect(boost::bind(&CWalletInterface::SyncTransaction, pwalletIn, _1, _2, _3));

@cvcook7

What version of source are you trying to build (a branch, or a tag, or a commit)?

What are options you provided to the configure script?

Have you successfully built with depends?

Hi @hebasto ,

Thanks for your reply. I have actually found a way to solve the problem. I just needed to add the following to the main.cpp so that it could work with my boost 1.77.

#include <boost/bind/bind.hpp> 
using namespace boost::placeholders;

I think it is because the Bind placeholders (_1, _2, ...) in the global namespace are deprecated in newer versions of boost. Thanks.
