Issues compiling from source

[shitbox120]

I have been breaking my head for 2 days and do not know what library I am missing. This is the error I am seeing.

` validation.cpp: In constructor ‘ConnectTrace::ConnectTrace(CTxMemPool&)’: validation.cpp:3103:94: error: ‘_1’ was not declared in this scope 3103 | pool.NotifyEntryRemoved.connect(boost::bind(&ConnectTrace::NotifyEntryRemoved, this, _1, 2)); | ^~ validation.cpp:3103:94: note: suggested alternatives: In file included from /usr/include/boost/mpl/aux/include_preprocessed.hpp:37, from /usr/include/boost/mpl/placeholders.hpp:43, from /usr/include/boost/iterator/iterator_categories.hpp:16, from /usr/include/boost/iterator/iterator_facade.hpp:13, from /usr/include/boost/filesystem/path.hpp:22, from /usr/include/boost/filesystem.hpp:16, from ./fs.h:11, from ./util.h:20, from primitives/block.h:13, from core_memusage.h:9, from coins.h:11, from validation.h:16, from validation.cpp:8:

I am using Ubuntu 20 with DB 4.8 . I have flowed it step by step.

./configure gives me this.

UPDATE: I am now able to make it to this final point. Am i missing a depend or do i have the wrong version of c?

I have the same problem when compiling on arm or x64 linux... I tried to compile with c++17 but i still have the problem

[yoyo20016]

@AndyNeoxa @shitbox120 I think I fixed the problem after spending by whole evening on it. The httpserver.cpp is missing this line #include <deque> on the top of the file. I complied the wallet for aarch64 and it works(it started and I am syncing the blockchain) Also on the makefile I made some changes for using c++17 and not c++14 but I think the second change is not required.

I also modified the validation.cpp as this:

Look in the code_modifications_neoxa.txt

And validationinterface.cpp as this :

`Look in the code_modifications_neoxa.txt

And validation.cpp:

`Look in the code_modifications_neoxa.txt

The most important changes are to change the placeholder binding '_1','_2','_3' by 'boost::placeholders::_1','boost::placeholders::_2','boost::placeholders::_3' and to add '#include <boost/bind.hpp>' to the files that uses thoses placeholders
