I think this is about the following line in debian/rules: optimflags = `DEB_BUILD_MAINT_OPTIONS=optimize=-lto dpkg-buildflags --get CFLAGS` https://sources.debian.org/src/r-base/4.4.0-2/debian/rules/#L101 ...which later propagares to cxxflags = $(optimflags) and eventually CXXFLAGS="$(cxxflags)" ... ./configure. On Sid, dpkg-buildflags --get CFLAGS includes -Werror=implicit-function-declaration, which g++ doesn't like: root@020af1fe3ba2:/# g++ -Werror=implicit-function-declaration -c ex.cpp cc1plus: warning: '-Werror=' argument '-Werror=implicit-function-declaration' is not valid for C++ -- Best regards, Ivan _______________________________________________ R-SIG-Debian mailing list R-SIG-Debian@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-debian
