What
Updates the Bitcoin Knots installation guide to use CMake instead of Autotools for versions 29.x and later.
Why
Bitcoin Knots v29.x (following Bitcoin Core) migrated from Autotools to CMake as the build system. The
autogen.shscript no longer exists in the source tree, causing installation failures when users follow the current guide. This is a breaking change that prevents users from successfully compiling Bitcoin Knots v29.x and later.How
autogen.shand./configuresteps with CMake configuration commandsmkdir build && cd build, thencmake ..with optimization flags-DBUILD_BENCH=OFF -DBUILD_TESTS=OFF -DBUILD_GUI=OFFScope
This is a necessary update to keep the guide functional for current Bitcoin Knots versions.
Test & maintenance
Testing:
bitcoind --versiondisplays Core version to obfuscate Knots informationMaintenance:
This change should remain stable as CMake is now the standard build system for Bitcoin Knots going forward. Future versions (v30.x+) will continue using CMake unless another major migration occurs (unlikely in near term).
I'm willing to update this section if CMake configuration changes in future versions.
Note for v28.x users:
The old Autotools method still works for v28.x and earlier. Consider adding a version selector or note at the beginning if backward compatibility is needed.
