Linking Error

[Olivier6767]

I just updated open-zwave and Domoticz to the latest release. When linking Domoticz I now get the following error:

[100%] Linking CXX executable domoticz
/usr/bin/ld: /home/Services/domotique/open-zwave-read-only/libopenzwave.a(DNSImpl.o): undefined reference to symbol 'ns_initparse@@GLIBC_2.9'

Could you make sure there is no newer commit ? I recently added a check for the resolv library On what system are you building ?

Could you try adding -lresolv at line 741 of CMakeList.txt

[gizmocuz]

After a git pull, remove the CMakeFile/Cache folder/file

[Olivier6767]

I'm building on Ubuntu 18.04. I just made a new Git Pull. I've a lto of files / folders in CMKaeFiles, which one do I need to remove ? In the meantime, I tried Make Clean / Make It is compiling now...

[gizmocuz]

Remove the folder CMakeFiles and the file CMakeCache.txt then issue

cmake -DCMAKE_BUILD_TYPE=Release CMakeLists.txt -DUSE_OPENSSL_STATIC="NO"

then make

[norrland1]

I'm also on Ubuntu and got same issue. Worked by adding -lresolv as you said.

Edit: Ran : cmake -DCMAKE_BUILD_TYPE=Release CMakeLists.txt -DUSE_OPENSSL_STATIC="NO"

But did not delete old files first. Did not work.

[gizmocuz]

@norrland1 , if you do a 'git pull' it should already be added in the CMake file

[norrland1]

Can't see it on line 741 but on line 691. Reset and building again.

$ git pull Already up to date.

IF-statement around line 741:

IF(CMAKE_SYSTEM_NAME STREQUAL "Darwin")

ENDIF()

[gizmocuz]

@norrland1 , yes thats ok... closing issue

[gizmocuz]

At least.. i hope it's solved..

[gizmocuz]

Maybe it is a combination of both... final build running here

[norrland1]

Did a complete reset so build is taking some time, at 84% now....

[gizmocuz]

I think we only have to add it ~line 741 after -lrt ... building again...

[Olivier6767]

Ok, I did git pull, removed CMakeFiles folder and CMakeCache.txt file, issued cmake -DCMAKE_BUILD_TYPE=Release CMakeLists.txt -DUSE_OPENSSL_STATIC="NO" then make

I'm still having the error: [100%] Linking CXX executable domoticz /usr/bin/ld: /home/Services/domotique/open-zwave-read-only/libopenzwave.a(DNSImpl.o): undefined reference to symbol 'ns_initparse@@GLIBC_2.9' /usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/libresolv.so: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status CMakeFiles/domoticz.dir/build.make:3635: recipe for target 'domoticz' failed make[2]: *** [domoticz] Error 1 CMakeFiles/Makefile2:77: recipe for target 'CMakeFiles/domoticz.dir/all' failed make[1]: *** [CMakeFiles/domoticz.dir/all] Error 2 Makefile:151: recipe for target 'all' failed make: *** [all] Error 2

[norrland1]

Yes, got same issue now.

[gizmocuz]

Few minutes...

[norrland1]

It does the trick, works fine if I add it to line 742.

target_link_libraries(domoticz -lresolv -lrt ${Boost_LIBRARIES} ${ZLIB_LIBRARIES} ${MINIZIP_LIBRARIES} ${CURL_LIBRARIES} pthread ${LUA_LIBRARIES} ${MQTT_LIBRARIES} ${SQLite_LIBRARIES} ${CMAKE_DL_LIBS} ${TELLDUS_LIBRARIES} ${EXECINFO_LIBRARIES})

[gizmocuz]

Yep it's building... but does it work for OpenBSD/Darwin ? Time will tell... If you do a 'git pull' it should work correctly now...

[norrland1]

Yes got it, looks good now, at least from my end ;)

[Olivier6767]

Yes I confirm, git pull, then make. All good. Thanks!

[petergebruers]

but does it work for OpenBSD/Darwin ? Time will tell...

Darwin did not build, because of dependency on libresolv, but this PR fixes that: https://github.com/domoticz/domoticz/pull/3526

[gizmocuz]

Thanks all for the help ! I think it will have to be added for OpenBSD as well ;)

[pipiche38]

Seems that I'm having the same on Fedora29

[gizmocuz]

@pipiche38 , could you explain a bit more... in the latest CMakeList.txt we added the resolv library Is it working now or does it now work ?

[pipiche38]

Sorry for the confusion. I switch to an existing system, and no issue at link time. So problem on my end.

[gizmocuz]

Hope all works find... closing issue
