Package: dpkg-dev
Version: 1.22.11
Severity: normal
dpkg-buildflags has started tightening build conditions such that implicit declarations are
now treated as errors (C flag -Werror=implicit-function-declaration)
This is a problem for scalapack (probably blas too), which has an
ancient code base without headers, so implicit function declarations
all the way through
dpkg-buildflags provides the facility to switch off the error
condition by setting
export DEB_BUILD_MAINT_OPTIONS = qa=-bug-implicit-func
in debian/rules, which I've done for scalapack 2.2.1-4exp4.
This fixes the scalapack for all architectures
https://buildd.debian.org/status/package.php?p=scalapack&suite=experimental except powerpc
https://buildd.debian.org/status/fetch.php?pkg=scalapack&arch=powerpc&ver=2.2.1-4exp4&stamp=1726724534&raw=0
On powerpc, I can see other dpkg-buildflags options,
-g -O2 -ffile-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security
but a flag for implicit-function-declaration is missing (whether
-Werror or -Wno-error).
So dpkg-buildflags on powerpc does not seem to be processing the qa=-bug-implicit-func option in DEB_BUILD_MAINT_OPTIONS.
