Source: qtwebkit Version: 2.3.2.dfsg-2 Severity: important User: debian-h...@lists.debian.org Usertags: hurd Tags: patch
Hello, qtwebkit currently puts hurd buildds on their knees because its build systems uses "make -j", i.e. without specifying the requested parallelism level, which means unbound parallelism, which when building c++ code basically means filling dozens of gigabytes of memory. This apparently comes from ./Tools/Scripts/webkitdirs.pm which for unknown platforms makes numberOfCPUs() return an empty string, which thus ends up with "make -j". The attached patch makes qtwebkit default to 1 instead of defaulting to unbound parallelism. Perhaps upstream will also prefer to try to use the portable way, sysconf(_SC_NPROCESSORS_ONLN) (I don't know the perl equivalent).
