Homebrew Boost 1.78 breaks external signer configure #24413
Description
Test on macOS 12.2.1 against the master branch. #24397 doesn't fix it.
brew info boost
boost: stable 1.78.0 (bottled), HEAD
...
./configure --enable-external-signer
...
checking for boostlib >= 1.64.0 (106400)... yes
checking whether Boost.Process can be used... no
configure: error: External signing is not supported for this Boost version
It does work with boost 1.76 (there was no 1.77 release in home-brew):
brew install [email protected]
...
LDFLAGS="-L/usr/local/opt/[email protected]/lib" CPPFLAGS="-I/usr/local/opt/[email protected]/include" ./configure --enable-external-signer
...
checking for boostlib >= 1.64.0 (106400)... yes
checking whether Boost.Process can be used... yes
...
Options used to compile and link:
external signer = yes
There's nothing in the release notes about Boost.Process for either 1.77 or 1.78.
The Homebrew formula changes are nothing but a trivial version and hash bump.
