Hi

I am trying to compile last mumble version in Windows 11 and Ubuntu.

I had some minor problems compiling vcpkg in both Windows and Linux because mumble-voip-ice-3.7.tar.gz real hash was "205b3ce0fa0ecc157944dd4dae5d9c68c54f07e7b0b8012beea83d83870bb7df8c21f930b6239b6c0dd49fb758ce9a58b1e2670d0de14349a582c58f73a2fafa" instead of the value included in the ports/zeroc-ice-mumble/portfile.cmake file: "d91d88459b4bca14cf4a8addf642246a0cdd5b7bf740f916d3eead2f7d7e0b52bc3a2b8af2f024e63d05baa0b258f5a5676bc205f379387fb233dd6b9bb81228" but I finally got mumble and murmur compiled in Windows.

Now, I am trying to generate mumble in Ubuntu. I achieved to compile vcpkg (using https://github.com/mumble-voip/mumble/blob/master/scripts/vcpkg/get_mumble_dependencies.sh script), but I get a link error when I try to generate mumble:

mkdir build && cd build
cmake ..
cmake "-DVCPKG_TARGET_TRIPLET=x64-linux" "-Dstatic=ON" "-DCMAKE_TOOLCHAIN_FILE=$HOME/vcpkg/scripts/buildsystems/vcpkg.cmake" "-DIce_HOME=$HOME/vcpkg/installed/x64-linux" "-DCMAKE_BUILD_TYPE=Release" ..
make

I the the following undefined references:

[ 90%] Built target mumble_autogen

OS and gcc version follow:

Linux cozuelos 6.5.0-27-generic #28~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Fri Mar 15 10:51:06 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0

I have googled the problem but I couldn't find anything which could help me to solve the problem. Is there any hint that I could use to deal with it?

Thanks and kind regards.

Have you also tried cleaning the build directory? Maybe static is cached to OFF...

Hi

I have finally been able to compile and run mumble in Ubuntu but I don't know if I have done it the right way. I found that the problems where related with the content of build/src/mumble/mumble_client_object_lib_plugin_import.cpp file

Q_IMPORT_PLUGIN(QSvgIconPlugin)
Q_IMPORT_PLUGIN(QSvgPlugin)
Q_IMPORT_PLUGIN(QXcbIntegrationPlugin)

and I figured out that they were generated because of the src/mumble/CMakeLists.txt content. I have changed the following lines:

pacebes@toribio:~/ubuntu/desarrollo/mumble$ diff src/mumble/CMakeLists.txt src/mumble/CMakeLists.txt.orig 

549,562c549,562
< ##if(static)
< ##	if(TARGET Qt5::QSQLiteDriverPlugin)
< ##		include_qt_plugin(mumble_client_object_lib PRIVATE "QSQLiteDriverPlugin")
< ##		target_link_libraries(mumble_client_object_lib PUBLIC Qt5::QSQLiteDriverPlugin)
< ##	endif()
< ##	if(TARGET Qt5::QSvgIconPlugin)
< ##		include_qt_plugin(mumble_client_object_lib PRIVATE "QSvgIconPlugin")
< ##		target_link_libraries(mumble_client_object_lib PUBLIC Qt5::QSvgIconPlugin)
< ##	endif()
< ##	if(TARGET Qt5::QSvgPlugin)
< ##		include_qt_plugin(mumble_client_object_lib PRIVATE "QSvgPlugin")
< ##		target_link_libraries(mumble_client_object_lib PUBLIC Qt5::QSvgPlugin)
< ##	endif()
< ##endif()

Now mumble now compiles and runs on Ubuntu. I don't know it this is the right option to deal with the issue or not. Any Idea ???

Thanks in advance

You have to enable the static option (-Dstatic=ON) when compiling in a static environment.

Thanks for your answer.

I have tried again your suggestion (I have already tried this following https://github.com/mumble-voip/mumble/blob/master/docs/dev/build-instructions/build_static.md instructions):

make clean
cmake "-DVCPKG_TARGET_TRIPLET=x64-linux" "-Dstatic=ON" "-DCMAKE_TOOLCHAIN_FILE=$HOME/vcpkg/scripts/buildsystems/vcpkg.cmake" "-DIce_HOME=$HOME/vcpkg/installed/x64-linux" "-DCMAKE_BUILD_TYPE=Release" ..
make

but I get again the same problem:

lto-wrapper: warning: using serial compilation of 79 LTRANS jobs
/usr/bin/ld: /tmp/cc3ddpai.ltrans78.ltrans.o: in function `_sub_I_65535_0.0':
<artificial>:(.text.startup+0xa44): undefined reference to `qt_static_plugin_QSvgIconPlugin()'
/usr/bin/ld: <artificial>:(.text.startup+0xa54): undefined reference to `qt_static_plugin_QSvgPlugin()'
/usr/bin/ld: <artificial>:(.text.startup+0xa64): undefined reference to `qt_static_plugin_QXcbIntegrationPlugin()'
collect2: error: ld returned 1 exit status
make[2]: *** [src/mumble/CMakeFiles/mumble.dir/build.make:421: mumble] Error 1
make[2]: Leaving directory '/home/pacebes/ubuntu/desarrollo/mumble/build'
make[1]: *** [CMakeFiles/Makefile2:1454: src/mumble/CMakeFiles/mumble.dir/all] Error 2
make[1]: Leaving directory '/home/pacebes/ubuntu/desarrollo/mumble/build'
make: *** [Makefile:136: all] Error 2

Which is consistent with the fact that these libraries are only included when static is ON (CMakeLists.txt)

if(static)
 	if(TARGET Qt5::QSQLiteDriverPlugin)
 		include_qt_plugin(mumble_client_object_lib PRIVATE "QSQLiteDriverPlugin")
 		target_link_libraries(mumble_client_object_lib PUBLIC Qt5::QSQLiteDriverPlugin)

As I commented in the previous I have now successfully compiled mumble client (not murmur server) patching the CMakeLists.txt file but it seems a bit odd to me that this was the right way. There must be a simpler solution I don't find..

Kind Regards

Thanks!

You are right.

I have deleted the local repository and I've started from the beginning again (only mumble, not vcpkg):

rm -rf mumble
git clone https://github.com/mumble-voip/mumble/
cd mumble
git submodule update --init --recursive
mkdir build && cd build
cmake "-DVCPKG_TARGET_TRIPLET=x64-linux" "-Dstatic=ON" "-DCMAKE_TOOLCHAIN_FILE=$HOME/vcpkg/scripts/buildsystems/vcpkg.cmake" "-DIce_HOME=$HOME/vcpkg/installed/x64-linux" "-DCMAKE_BUILD_TYPE=Release" ..
make VERBOSE=1

And it now works smoothly..

Thank you so much !!
