Build failed for man pages (cmake)

Asked by islander

Hello, i'm trying to publish package of small utility built with CMake.

Build failed with this error:

 fakeroot debian/rules binary
cd build_dir; cmake -DCOMPONENT=Unspecified -DCMAKE_INSTALL_PREFIX=../debian/tmp/usr -P cmake_install.cmake
-- Install configuration: ""
-- Install component: "Unspecified"

CMake Error at cmake_install.cmake:101 (file):
  file INSTALL cannot copy file
  "/<<PKGBUILDDIR>>/build_dir/xkb-switch.1.xz" to
  "/usr/share/man/man1/xkb-switch.1.xz".

My debian/rules is:

#!/usr/bin/make -f

BUILDDIR = build_dir

build:
 mkdir -p $(BUILDDIR)
 cd $(BUILDDIR); cmake -DOPT_BIN_SUFFIX=ON -DCMAKE_INSTALL_PREFIX=/usr ..
 make -C $(BUILDDIR) preinstall
 touch build

binary: binary-indep binary-arch

binary-indep: build

binary-arch: build
 cd $(BUILDDIR); cmake -DCOMPONENT=Unspecified -DCMAKE_INSTALL_PREFIX=../debian/tmp/usr -P cmake_install.cmake
 mkdir -p debian/tmp/DEBIAN
 dpkg-gensymbols -pxkb-switch
 dh_shlibdeps
 dpkg-gencontrol -pxkb-switch
 dpkg --build debian/tmp ..

clean:
 rm -f build
 rm -rf $(BUILDDIR)

.PHONY: binary binary-arch binary-indep clean

My cmake_install.cmake is:

if("x${CMAKE_INSTALL_COMPONENT}x" STREQUAL "xUnspecifiedx" OR NOT CMAKE_INSTALL_COMPONENT)
  file(INSTALL DESTINATION "${CMAKE_INSTALL_PREFIX}/share/man/man1" TYPE FILE FILES "/home/user/src/debian-build/xkb-switch.1.xz")
endif()

My CMakeLists.txt is:

SET(MANDIR "share/man" CACHE STRING "Manpages installation path")
INSTALL(FILES ${compressed_man}
    DESTINATION ${MANDIR}/man${man_type})

How can I fix this issue?
Or have we good practices to build man files on launchpad?

This isn't a Launchpad problem - you should be able to reproduce exactly the same thing locally using sbuild (https://wiki.ubuntu.com/SimpleSbuild).

The problem appears to be that your build system is trying to install the man page directly to /usr/share/man/... rather than to a prefix, but I'm not clear why your setting of CMAKE_INSTALL_PREFIX apparently isn't taking effect here. In general we can't debug your build system for you, though - I suggest focusing on reproducing the problem in sbuild and then you can debug it locally.

Ok, thanks, I'll try to install sbuild locally and test there.

Can you help with this problem?
