Build from source without Boost?

[benwills]

Operating System: Ubuntu 20.04
Source Code URL: https://github.com/manticoresoftware/manticoresearch/archive/3.5.2.tar.gz

The documentation references Boost needing to be used by Galera: https://manual.manticoresearch.com/Installation/Compiling_from_sources#Available-features-and-their-dependencies

I'm trying to build a fairly minimal install from source and don't need replication. For build options, I've referenced the documentation for building from source, https://github.com/manticoresoftware/manticoresearch/blob/master/config/config_cmake.h.in, and grepped "USE_" and "WITH_" across the all source code.

This is how I'm running cmake:
cmake \ -DUSE_BISON=0 \ -DUSE_FLEX=0 \ -DUSE_GALERA=0 \ -DUSE_ICU=0 \ -DUSE_LIBEXPAT=0 \ -DUSE_LIBICONV=0 \ -DUSE_LIBSTEMMER=0 \ -DUSE_MYSQL=0 \ -DUSE_ODBC=0 \ -DUSE_PGSQL=0 \ -DUSE_RE2=0 \ -DUSE_SSL=0 \ -DUSE_SYSLOG=1 \ -DUSE_ZLIB=1 \ -DWITH_EXPAT=0 \ -DWITH_GALERA=0 \ -DWITH_ICONV=0 \ -DWITH_ICU=0 \ -DWITH_MYSQL=0 \ -DWITH_ODBC=0 \ -DWITH_PGSQL=0 \ -DWITH_RE2=0 \ -DWITH_STEMMER=0 \ -DWITH_SYSTEMD=1 \ -DWITH_SYSTEMD=1 \ -DWITH_ZLIB=1 \ -DCMAKE_BUILD_TYPE=RelWithDebInfo

cmake outputs a line saying "-- Could NOT find Boost (missing: Boost_INCLUDE_DIR context) (Required is at least version "1.61.0")", which is then followed by downloading Boost.

Is there a way to build from source without including Boost and/or creating a fairly minimal install? Or is Boost now required?

Thanks.

Is there a way to build from source without including Boost

Try -DWITH_BOOST=OFF

and/or creating a fairly minimal install?

Try -DBUILD_TESTING=OFF -DDL_EXPAT=OFF -DDL_MYSQL=OFF -DDL_UNIXODBC=OFF -DSTRICT_BUILD_FLAGS=OFF -DSYSTEM_ASIO=OFF -DUSE_GALERA=OFF -DUSE_SSL=OFF -DWITH_BOOST=OFF -DWITH_EXPAT=OFF -DWITH_ICU=OFF -DWITH_ICU_FORCE_STATIC=OFF -DWITH_MYSQL=OFF -DWITH_ODBC=OFF -DWITH_STEMMER=OFF -DSTATIC_BINARY=ON -DHAVE_GETADDRINFO_A=OFF

I tried both of your suggestions, including with -DWITH_BOOST=0, and all of them proceeded to download Boost. Each attempt was also made with a freshly-unzipped source directory.

No, no easy way.
Boost.context is essential part and can't be avoided to build with.
If you need to build from sources you can either install boost on build host, either (which is essentially the same) use docker image with boost installed (you can find bunch of them in dist/build_dockers folder).

kind of 'minimal' build would be to extract boost.context from the whole boost and used, but it is also not an easy task by itself. Final version of boost.context we link with is a static library from couple of sources, taking just 4-20Kb (depends from debug symbols attached), but building from sources invokes many parts of not very important but still necessary stuff from other parts of boost.

Theoretically the only lib may be subsetted and patched to be standalone, but don't think it is a good idea in general as with such customization we have then support this code, and not just refer to upstream boost for it.
