[pkg-db-devel] Bug#752368: src:db5.3: FTCBFS on any architecture: installs build_signature_$DEB_HOST_ARCH.txt which is not built

[Helmut Grohne]

Package: src:db5.3
Version: 5.3.28-3.1
Severity: important
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

Dear db5.3 maintainers,

Currently db5.3 fails to cross-build from source for any architecture,
because override_dh_installdocs tries to install a file never built:

| # Install build_signature_x32.txt to docs
| install -m 644 debian/build_signature_x32.txt /tmp/buildd/db5.3/db5.3-5.3.28/debian/libdb5.3/usr/share/doc/libdb5.3/
| install: cannot stat 'debian/build_signature_x32.txt': No such file or directory
| debian/rules:211: recipe for target 'override_dh_installdocs' failed
| make[1]: *** [override_dh_installdocs] Error 1
| make[1]: Leaving directory '/tmp/buildd/db5.3/db5.3-5.3.28'
| debian/rules:127: recipe for target 'binary-arch' failed
| make: *** [binary-arch] Error 2
| dpkg-buildpackage: error: debian/rules binary-arch gave error exit status 2

I suggest only installing this file when building it. Please consider my
patch attached.

Helmut
