Building Debian packages with scan-build
This page describes the different solutions you have when you want to build a Debian package using scan-build, the static analysis tool from the LLVM suite.
A few solutions I have heard of, some of them work but some of them cannot.
Just do :
Working well, this is one good solution to keep. This is simply the previous solution, wrapped up in a new script. When you are using a tool which calls dpkg-buildpackage (e.g sbuild).
mv /usr/bin/dpkg-buildpackage /usr/bin/dpkg-buildpackage.faked cat > /usr/bin/dpkg-buildpackage <<EOF #!/bin/bash scan-build dpkg-buildpackage.faked $@ EOF chmod +x /usr/bin/dpkg-buildpackage dpkg-buildpackage
Wrapping the make command in scan-build is not sufficient because scan-build needs also to be called for the "configure" phase. This technique may lead to unexpected results.
Does not work with scan-build because scan-build is not a real compiler it is a wrapper of ccc-analyzer which is itself a wrapper calling the clang -cc1 frontend.
mkdir /tmp/scan-build-path ln -s /usr/bin/g++ /tmp/scan-build-path/ export PATH=/tmp/scan-build-path:$PATH dpkg-buildpackage
