[WIP] build: Add CMake-based build system #25305

hebasto commented at 10:09 AM on June 8, 2022: member

Done:

bitcoind executable, could be disabled with -DBUILD_DAEMON=OFF
bitcoin-cli executable, could be disabled with -DBUILD_CLI=OFF
libbitcoinconsensus shared library, could be disabled with -DBUILD_BITCOINCONSENSUS_LIB=OFF
libbitcoinkernel shared library, could be disabled with -DBUILD_BITCOINKERNEL_LIB=OFF
wallet support (SQLite, not BDB), could be disabled with -DENABLE_WALLET=OFF
ccache support, could be disabled with -DUSE_CCACHE=OFF
cross-compiling, including Windows builds with DEBUG=1
reduce exported symbols support, could be enabled with -DREDUCE_EXPORTS=ON (broken on macOS yet)

Not implemented yet:

optional package support
BDB wallet support
...

Need to be fixed:

-DREDUCE_EXPORTS=ON on macOS

A benefit to note -- cross compiling libbitcoinconsensus.dll with DEBUG=1 just works (see #19772)

Native compiling has been tested on the following OSes:

Ubuntu 22.04
macOS Monterey
FreeBSD 12.3

rm -rf build && cmake -S . -B build
cmake --build build

OpenBSD 7.1

rm -rf build && cmake -DCMAKE_MAKE_PROGRAM=gmake -S . -B build
cmake --build build

Cross compiling for Windows on Ubuntu 22.04

make -j$(nproc) -C depends HOST=x86_64-w64-mingw32 NO_QT=1
rm -rf build && cmake -C $PWD/depends/x86_64-w64-mingw32/share/depends.cmake -S . -B build
cmake --build build -j$(nproc)

Cross compiling for macOS on Ubuntu 22.04

make -j$(nproc) -C depends HOST=x86_64-apple-darwin NO_QT=1
rm -rf build && cmake -C $PWD/depends/x86_64-apple-darwin/share/depends.cmake -S . -B build
cmake --build build -j$(nproc)
