[proposal] Make static release builds

[l-n-s]

Quote from IRC:

SGLG hints to the devs of i2pd that it would be really nice if there were a statically compiled tar.gz'ed pre-compiled version that could be extracted and ran from the folder it was extracted to.

Portable binary? Sounds like a good idea.

I have this for linux armhf, would be nice to have a script that pulls in dependencies and builds a static release.

@hagen-i2p had some concerns about static builds for linux

[hagen-i2p]

Several releases ago there was issues with static build on unix with glibc/gethostbyname(), because it's nsswitch support with pluggable modules.

I'll try again.

[hagen-i2p]

The same warning. See message in last line.

/usr/lib/x86_64-linux-gnu/libcrypto.a(dso_dlfcn.o): In function dlfcn_globallookup': (.text+0x11): warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking libi2pd.a(Reseed.o): In functionboost::asio::detail::socket_ops::getaddrinfo(char const_, char const_, addrinfo const&, addrinfo**, boost::system::error_code&)': /usr/include/boost/asio/detail/impl/socket_ops.ipp:3177: warning: Using 'getaddrinfo' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking

@hagen-i2p that commit fixed the option to statically build awesome!

Since this is a proposal for the static builds can I request static builds for armel? I have been trying it for a while now with a armel cmake toolchain using -DCMAKE_TOOLCHAIN_FILE= without any succes.

I've just tried to build static i2pd with openssl and it gave me such error:

Google search showed that to fix that issue, I'll need to add -ldl flag here

After that, it compiles and works perfect.

EDIT: I build with such command:

make LIBDIR="$STATDIR/lib" USE_STATIC=yes INCFLAGS="-I$STATDIR/include"

Did we still need that issue?

[l-n-s]

There is big demand for static Raspberry Pi build, so I guess yes

[r4sas]

Now here no problems to build staticly, because I already created needed chroots for building packages, where I can also build static binary.
