pbuilder-dist fails if cmake can't find non-mandatary c++ feature support?

  • 772

I'm trying to submit a deb to my PPA according to this manual:
https://packaging.ubuntu.com/html/packaging-new-software.html
I'm able to build my app with bzr builddeb -- -nc -us -uc and to sign it with bzr builddeb -S. But execution of pbuilder-dist groovy build myproject_0.2.8-1.dsc in ../build-area fails.
Full log is available in pastebin: https://pastebin.com/whr6Qsd1

I believe that the problem is in following piece:

Determining if the CXX compiler accepts the flag -fno-keep-inline-dllexport failed with the following output:
Change Dir: /build/myapp-0.2.8/obj-x86_64-linux-gnu/CMakeFiles/CMakeTmp

make: *** [debian/rules:6: binary] Error 25
dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2

So, cmake is checking that /usr/c++ supports -fno-keep-inline-dllexport. Compiller ends with 1 bcs it doesn't support it, cmake returns 2 and dh_auto_configure painics.

If I execute cmake on my system I'm getting following stdout:

-- Checking to see if CXX compiler accepts flag -ffunction-sections -fdata-sections -Wl,--gc-sections
-- Checking to see if CXX compiler accepts flag -ffunction-sections -fdata-sections -Wl,--gc-sections - yes
-- Checking to see if CXX compiler accepts flag -fno-keep-inline-dllexport
-- Checking to see if CXX compiler accepts flag -fno-keep-inline-dllexport - no
-- Checking to see if CXX compiler accepts flag -Werror=return-type
-- Checking to see if CXX compiler accepts flag -Werror=return-type - yes

So even compiller on my system doesn't support -fno-keep-inline-dllexport. And I'm fine with that. It doesn't matter for me. cmake not fails.

It looks that the failed check of non-mandatory feature by cmake ruins whole pbuilder-dist process. Are there any way to change this behaviour or i'm missing something?

P.s. My build-depends are: debhelper-compat (= 13), cmake (>=2.8.9), gcc (>=4.6), qt5-qmake (>= 5.4), qtbase5-dev (>= 5.4), libtiff5-dev (>= 4.0.3), libjpeg8-dev (>= 8c), libpng-dev (>=1.6.2)

    I am not certain about the exact issue prompted by you configuration. But two possible solutions are

    1. Changing -std=c++0x to -std=c++11.
    2. Remove option -fno-keep-inline-dllexport.

    Please check your configuration files, where to modify this.

    Prior to this, you can check if any of these options would work. Go to the parent directory of CMakeFiles and try replicating the failed command at the command line, with the suggested modifications:

    1. /usr/bin/c++ -std=c++11 -fno-keep-inline-dllexport -o CMakeFiles/cmTC_3ab02.dir/DummyCXXFile.cxx.o -c /usr/share/cmake-3.16/Modules/DummyCXXFile.cxx
    2. /usr/bin/c++ -std=c++0x -o CMakeFiles/cmTC_3ab02.dir/DummyCXXFile.cxx.o -c /usr/share/cmake-3.16/Modules/DummyCXXFile.cxx

    For this to work, you would likely need to call first cmake --debug-trycompile (source).

    Notes about your pastebin (messages worth noting, even though not necessarily problems) and procedure:

    1. You have tons of ln: failed to create hard link '...' => '...': Invalid cross-device link messages.
    2. There is a problem reported with Qt5LinguistTools. Perhaps it is worth installing qttools5-dev prior to what you did.
    3. It reports Configuring incomplete, errors occurred!. It is worth checking what are possible sources of problems.
    4. It helps a lot if you specify the exact list of commands you issued, including the directory where each command was issued.
    5. What do you mean by "If I execute cmake on my system..."? Same as point above.
