Basically build dependencies are +just like install dependencies, but they are resolved against the build system +just after parsing the spec file. Syntactically, build dependencies look just +like install dependencies in a spec file with "Build" prefixed: + + BuildPrereqs: + BuildRequires: + BuildConflicts: + +All the above dependencies include versions, files, existence/range tests, etc. +The build dependency checking can also be turned off with --nodeps if necessary +just like install dependency checking can. Eventually, build dependencies will +be automated in rpm, but the major impediment to that effort is the engineering +required to maintain the pretense that src rpm's are "noarch". + +Meanwhile, I've added a package called "InDependence-1.0" to powertools-6.2 +that may be of use in detecting build dependencies that can be added to +spec files as part of rebuilding packages for Red Hat 6.2. + +Here's a short example of how to generate the package/file names that were used +while building gnorpm using InDependence: + + rpm -U /mnt/redhat/comps/powertools/6.2/i386/InDependence-1.0-3.i386.rpm + rpm -i /mnt/redhat/comps/dist/6.2/SRPMS/gnorpm-0.9-11.src.rpm + cd /usr/src/redhat/SPECS + dep -detail rpm -ba gnorpm.spec >& xxx + ... + (the build will take longer since both dep and strace are pigs) + ... + grep -- '::' xxx > yyy + +========================================================================= +Aside: The dep perl wrapper is a "pig" only because it's exec'ing + rpm -qf <filename> + in order to turn filenames into package names. There are easier/faster + ways to get this information... + + There's no way to speed up the + /sbin/strace -q -etrace=open,execve -o ... + command itself.
