From: Thomas Hindoe Paaboel Andersen <pho...@gmail.com> scan-build is a static analyzer in llvm. As ususal static analyzers tend to mostly find theoretical bugs in software that has been in production for a while. For in-development code it can be useful to check if new issues is added as there is a chance to spot real problems before release. For systemd we are now down to 297 issues - the vast majority are false positives because the tool does not understand the cleanup attribute.
Running clang's static analyzer scan-build is a bit messy. You have to run both configure and make "inside" the build-scan tool. To have an easy shortcut from autogen.sh I thus call both directly from it. This makes it different from the other options in autogen.sh. I chose 's' for static analysis. scan-build is in the package clang-analyzer on fedora. On fedora we also need to set --use-analyzer=/usr/bin/clang --- autogen.sh | 3 +++ 1 file changed, 3 insertions(+) diff --git a/autogen.sh b/autogen.sh index 91df10a..b6d197d 100755 --- a/autogen.sh +++ b/autogen.sh @@ -65,6 +65,9 @@ elif [ "x$1" = "xa" ]; then elif [ "x$1" = "xl" ]; then ./configure CC=clang CFLAGS='-g -O0 -ftrapv -Wno-cast-align -Wno-gnu' --enable-kdbus $args make clean +elif [ "x$1" = "xs" ]; then + scan-build --use-analyzer=/usr/bin/clang ./configure CFLAGS='-g -O0 -ftrapv' --enable-kdbus $args + scan-build --use-analyzer=/usr/bin/clang make else echo echo "----------------------------------------------------------------" -- 1.8.4.2 _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
