Build-wrapper empty for c++ on linux

Hi,
I have been struggling with this. I have the following versions

  • build-wrapper-linux-x86 - build-wrapper, version 6.9 (linux-x86)
  • Ubuntu 18.04
  • sonarqube-developer-8.3.1.34397
  • SonarScanner 4.3.0.2102
  • Java 11.0.3 AdoptOpenJDK (64-bit)

I have run the following to compile, but still leaves build-wrapper-dump.json empty

**build-wrapper-linux-x86-64 --out-dir /opt/builddir sudo ./autogen.sh **


** 161 mkdir build**
** 162 cd build**
** 163 build-wrapper-linux-x86-64 --out-dir /opt/builddir sudo …/configure**
** 164 build-wrapper-linux-x86-64 --out-dir /opt/builddir sudo make clean all**
** 165 build-wrapper-linux-x86-64 --out-dir /opt/builddir sudo make check**

I have checked settings, permissions. My trial license will expire soon and need to ensure I can get this working and desired results are achieved before we purchase.

Hello @binie,
First, you only have to call build-wrapper once with the build command instead of 3 times.
Second, sudo shouldn’t be passed to build-wrapper.

So following the build commands that you provided it should be something like that:

sudo ./autogen.sh
mkdir build
cd build
sudo ../configure
sudo build-wrapper-linux-x86-64 --out-dir /opt/builddir make clean all
sudo make check

If this still fails please can you upload the full build-wrapper log file directly after executing these commands?

many thanks @Abbas_Sabra. The build-wrapper file gets created but is still empty.

I do notice that one of the functional test fails when I do a make check. Will this affect data being written to build-wrapper. I am trying to get the developers to look at this.
build-wrapperlog.txt (4.6 KB)

in addition, the following command comes back with an unknown command -
sudo build-wrapper-linux-x86-64 --out-dir /opt/builddir make clean all

I have to run it as
build-wrapper-linux-x86-64 --out-dir /opt/builddir sudo make clean all

@binie,
you cannot pass sudo to build-wrapper. Do you really need sudo to build your project?
try build-wrapper-linux-x86-64 --out-dir /opt/builddir make clean all

@Abbas_Sabra Thanks for all your help; I was able to get this to scan same code on ubuntu 18.04 and 20.04. We’ll move on to the next phase of getting justification :wave:t4: :muscle:t4:
