The "build-wrapper-dump.json" file was found but 0 C/C++/Objective-C

Must-share information (formatted with Markdown):

which versions are you using (SonarQube, Scanner, Plugin, and any relevant extension)

SonarQube Scanner 4.0.0.1744
 Java 11.0.3 AdoptOpenJDK (64-bit)
 Linux 5.4.0-91-generic amd64
 SonarQube server 8.9.1
CFamily plugin version: 6.20.1.32841

what are you trying to achieve
I have a project which has kotlin, java and C++ code. Java and Kotlin code smells are working fine, but when it comes to C++ I am getting following error.

what have you tried so far to achieve this
Instead of C++, if I enable CXX, it works fine, I mean I get the code smells and issues on dashboard.

Due to security reasons, I can’t share build-wrapper.log or json
Alternate : I tried to copy C++ rules to CXX - Seems not possible. Is there anyway I can do that ?

Hi @VishwasKulkarni ,

you are now wrapping the build call with the build-wrapper, you are currently wrapping the cmake configuration call, to have correct C++ analysis you should change the sonar-scanner call to the following:

rm -f build-wrapper-linux-x86.zip

wget <build-wrapper-linux-x86.zip from server>
unzip build-wrapper-linux-x86.zip
export BUILDSCANNER=`pwd`/build-wrapper-linux-x86/
export PATH=$PATH:${BUILDSCANNER}

cd control
cmake -S . -B . 
build-wrapper-linux-x86-64 --out-dir ../build_output  cmake --build . --target clean
cd ..

#Execution fails with above mentioned error,
sonar-scanner -X \
  -Dsonar.projectKey=<rootProj> \
  -Dsonar.host.url=<url> \
  -Dsonar.login=<login> \
  -Dsonar.branch.name=${BRANCH} \
  -Dsonar.java.binaries=control/** \
  -Dsonar.java.libraries=**/** \
  -Dsonar.c.file.suffixes=- \
  -Dsonar.cpp.file.suffixes=.h,.cc,.cpp,.cxx,.c++,.hh,.hpp,.hxx,.h++,.ipp \ 
  -Dsonar.cfamily.threads=$(nproc) \
  -Dsonar.cfamily.cache.enabled=false \
  -Dsonar.cfamily.build-wrapper-output=build_output

VishwasKulkarni · April 7, 2022, 7:58am

I tried with below command.

cd controller
cmake -S . -B . 
build-wrapper-linux-x86-64 --out-dir ../build_output  cmake --build . --target clean
exit_code_cxx=$?

cd ..
sonar-scanner \
  -Dsonar.projectKey=<rootProj> \
  -Dsonar.host.url=<url> \
  -Dsonar.login=<login> \
  -Dsonar.branch.name=${BRANCH} \
  -Dsonar.java.binaries=controller/** \
  -Dsonar.java.libraries=**/** \
  -Dsonar.c.file.suffixes=- \
  -Dsonar.cpp.file.suffixes=.h,.cc,.cpp,.cxx,.c++,.hh,.hpp,.hxx,.h++,.ipp \
  -**Dsonar.cfamily.threads=$(nproc)** \
  -Dsonar.cfamily.cache.enabled=false \
  -Dsonar.cfamily.build-wrapper-output=build_output

and it did not solve the issue. Got this error

Error during SonarQube Scanner execution **13:13:59** ERROR: Language of file 'controller/CMakeFiles/3.18.1/CompilerIdCXX/CMakeCXXCompilerId.cpp' can not be decided as the file matches patterns of both sonar.lang.patterns.cxx : **/*.cpp and sonar.lang.patterns.cpp : **/*.h,**/*.cc,**/*.cpp,**/*.cxx,**/*.c++,**/*.hh,**/*.hpp,**/*.hxx,**/*.h++,**/*.ipp

Trails:
I added "-Dsonar.cxx.file.suffixes=- " to disable CXX and tried again but got below error.

I feel I am making a mistake in sonar scanner command but I am not able to pinpoint it exactly.

Hi @VishwasKulkarni ,

the sonar-cxx plugin is not supported by SonarSource, I recommend either uninstalling it or referring to their support channel if interferes with the SonarSource CFamily plugin.

VishwasKulkarni · April 7, 2022, 8:06am

@mpaladin ,
I recommend either uninstalling it or referring to their support channel if interferes with the SonarSource CFamily plugin.

If possible could you provide links to their support channel.

And if possible could you tell me with the command you suggested I got the following error. What could be cause or any solution you want me to try.

Hi @VishwasKulkarni ,

I don’t think that they can co-exist, I highly recommend that you pick one or the other, just uninstall sonar-cxx and give it a try. About their support channel just use any search engine to find their page and their support channel.

VishwasKulkarni · April 7, 2022, 10:18am

@mpaladin
We un-installed sonar-cxx from MarketPlace in sonarqube UI. We tried different combinations of commands on sonar-scanner, but all of them ended on same error message.

But still facing the same error with following command

cd controller
cmake -S . -B . 
build-wrapper-linux-x86-64 --out-dir ../build_output  cmake --build . --target clean
exit_code_cxx=$?

Are there any other trial methods we could try ?

mpaladin · April 7, 2022, 12:13pm

Hi @VishwasKulkarni ,

I overlooked the command above which only runs clean target, it should be:

build-wrapper-linux-x86-64 --out-dir ../build_output  cmake --build . --clean-first

VishwasKulkarni · April 7, 2022, 3:36pm

Thank you @mpaladin . I appreciate it.

Just one more doubt, what if I have to link android NDK library liblog.so with cmake command like below

export ANDROID_NDK_LIB=/home/<builder>/sdk/ndk/22.0.7026061/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/lib/arm-linux-androideabi/28/liblog.so

cmake -S . -B . -D lib-log=${ANDROID_NDK_LIB}
build-wrapper-linux-x86-64 --out-dir ../build_output  cmake --build . --clean-first

I get following error message and complete C++ report. I did try different ways to link the library like below(example)

cmake -S . -B . -D log-lib=${ANDROID_NDK_LIB}
build-wrapper-linux-x86-64 --out-dir ../build_output cmake --build . --target clean
build-wrapper-linux-x86-64 --out-dir ../build_output cmake --build .

Result was same: Complete C++ report, and below error while compiling.

VishwasKulkarni · April 19, 2022, 6:36am

@mpaladin any suggestions ?

mpaladin · April 19, 2022, 6:52am

Hi @VishwasKulkarni ,

are you able to get a successful build without build-wrapper? Could you try to get a successful build without build-wrapper and post the commands sequence?
