compile error

[merkleID]

Hi,
I am experiencing a compile break on ubuntu 16.04-update and git fetch updated.

nohup log file says:

make[2]: Leaving directory '/root/git/multichain/src/secp256k1'
CXXLD libbitcoinconsensus.la
/usr/bin/ar: u' modifier ignored since D' is the default (see `U')

CXX protocol/multichaind-filter.o
In file included from protocol/filter.cpp:4:0:

compilation terminated.

make[1]: Leaving directory '/root/git/multichain/src'
Makefile:560: recipe for target 'all-recursive' failed
make: *** [all-recursive] Error 1

I posted the same compile error yesterday on multichain Q&A site, but it was under ubuntu 18.04, so I gave it a chance to compile also under ubuntu 16.04 but same error happens.

Thanks,
Luca

@lucaonelogin you installed v8 Engine ?

[medeirosfalante]

@lucaonelogin you did get it ?

I have installed the v8 Engine but I fail now:
CXX protocol/multichaind-filter.o
In file included from protocol/filter.cpp:8:0:
./v8/v8filter.h:86:5: error: ‘Global’ in namespace ‘v8’ does not name a type
v8::Globalv8::Context m_context;
^
./v8/v8filter.h:87:5: error: ‘Global’ in namespace ‘v8’ does not name a type
v8::Globalv8::Function m_filterFunction;

I have repoduced this error under ubuntu 14.04 64bit.

I have looked at the master: https://github.com/MultiChain/multichain/blob/master/README.md
Will try Build Google's V8 locally
Please use the instructions in V8.md to build and install V8 for use by MultiChain.
and see if this resolves the problem.

I've just stucked on v8 compile ("ninja -C $RELEASE" step) on errors like:

In file included from ../../third_party/antlr4/runtime/Cpp/runtime/src/./antlr4-runtime.h:149: ../../third_party/antlr4/runtime/Cpp/runtime/src/tree/pattern/ParseTreePattern.h:34:21: error: explicitly defaulted copy assignment operator is implicitly deleted [-Werror,-Wdefaulted-function-deleted] ParseTreePattern& operator=(ParseTreePattern const&) = default; ^ ../../third_party/antlr4/runtime/Cpp/runtime/src/tree/pattern/ParseTreePattern.h:97:13: note: copy assignment operator of 'ParseTreePattern' is implicitly deleted because field 'patternRuleIndex' is of const-qualified type 'const int' const int patternRuleIndex; ^ 4 errors generated.

Would be good to have some docker image for source compilation ...
