This my memo where I store the commands I’m using when building packages with pkgsrc (http://www.netbsd.org/docs/software/packages.html).
Determining the package dependencies:
$ bmake show-depends-pkgpath
Finding build references to a given package, e.g. libdrm:
$ egrep ‘libdrm|xf86driproto’ */*/buildlink3.mk
All the available targets are documented in The pkgsrc make target reference – NetBSD Wiki.
This is used to rebuild a patched package:
bmake distinfo && bmake clean && bmake build
The following builds and install the package:
bmake distinfo && bmake clean && bmake package
QNX specific issues are discussed in the forum http://community.qnx.com/sf/discussion/do/listTopics/projects.pkgsrc/discussion.general.
