Thanks, but this is what I was using already.

I'll try install.sh

Ok. In particular, you've already added the --enable-module-recovery switch?

I tried but I didn't know where to add it.

Add it to the ./configure line (but if you're going to install.sh, that's the preferred way to install anyway)

I tried install.sh and it says "/usr/local/include/boost/test/tools/old/impl.hpp:130: undefined reference to `boost::test_tools::tt_detail::equal_impl(wchar_t const*, wchar_t const*)"

When I ran "./configure --enable-module-recovery" it says "configure: WARNING: unrecognized options: --enable-module-recovery"

Maybe you didn't use the --build-boost arg? install.sh is best when it builds all dependencies and doesn't require system libs (to avoid version conflicts, etc).

Thanks, trying install.sh with --build-boost

It's for the secp256k1 configure script, btw.

install.sh will build the required version (you can see that it passes the args there when building if you take a peek at install.sh).

compiling now.

src/.libs/libbitcoin-system.so: undefined reference to `boost::re_detail_106900::put_mem_block(void*)

Can't say without seeing the system, but the 2 things I'd recommend when using install.sh: 1) Make sure the --prefix=/path path doesn't exist (or rm- rf it if it does), 2) If it looks like system boost is still being picked up by configure (I've seen this on some, but not all systems), use PKG_CONFIG_PATH=/home/me/install-path/lib/pkgconfig ./install.sh --prefix=/home/me/install-path --build-boost

A few edits there, but I think I got that right there 😉

Hmm ok but won't that install it in my home directory?

That example would install it in $HOME/install-path. You can pick wherever of course

It's not recommended to install to system as root, but I know some people that do that. It can cause future build issues when conflicts arise

I realize the docs literally say to do the sudo make install, so let me clarify that I don't recommend that, as it causes issues on future builds

Personally, I tend to go for options like this: https://github.com/libbitcoin/libbitcoin-system#building-icu-zlib-png-qrencode-andor-boost

How do I uninstall from root?

Not sure, personally, I haven't had to do that. You can try the standard 'make uninstall' from each of the repos I suppose(?)

Oh ok

Ok trying again

Aha it worked. Thank you!

Boost is problematic because it gets installed in so many variations by so many apps. DLL hell on Linux. The trick is to isolate it to a prefix dir, as you’ve done.

Can you tell me about what's going on with libsecp256k1? what does --enable-module-recovery actually do?

These may help: https://github.com/bitcoin-core/secp256k1/blob/master/configure.ac#L132

And Libbitcoin usage: https://github.com/libbitcoin/libbitcoin-system/blob/master/src/math/elliptic_curve.cpp

Ahh thanks.

How does libbitcoin-blockchain work without libbitcoin-consensus?

It uses its native script implementation in libbitcoin-system.

Oh ok

Does it work WITH libbitcoin-consensus? I'm asking because I just noticed something in libbitcoin-blockchain that says verify_script automatically fails if use_libconsensus is true!

I haven't tested it recently in master, but there are at least 2 version3 mainnet servers, and 1 of them runs with consensus, the other without. The last I did test it in master, it was also working well.

I think you are misinterpreting the source.

The failure only occurs if attempting to use libconsensus when it has not been compiled and linked.
