FreeBSD Ports: How can I see all dependencies for a port, and all subdependencies for those dependencies?

I'm trying to build a port which depends on apache-ant.

I thought I could run make build-depends-list to see all dependencies required by this port:

# make build-depends-list
/usr/ports/devel/apache-ant
/usr/ports/java/jdk16
/usr/ports/math/gmp

But after installing everything, the port had a dependency list which was a mile long:

apache-ant-1.8.1 desktop-file-utils-0.15_2 gamin-0.1.10_4 gettext-0.18.1.1 gio-fam-backend-2.26.1 glib-2.26.1_1 gmp-5.0.1 inputproto-2.0 javavmwrapper-2.3.5 kbproto-1.0.4 libX11-1.3.3_1,1 libXau-1.0.5 libXdmcp-1.0.3 libXext-1.1.1,1 libXi-1.3,1 libXtst-1.1.0 libiconv-1.13.1_1 libpthread-stubs-0.3_3 libxcb-1.7 pcre-8.12 perl-5.10.1_3 pkg-config-0.25_1 python26-2.6.6 recordproto-1.14 unzip-6.0 xextproto-7.1.1 xproto

This dependency list is a rude surprise, and I would like to know about it before I commit to installing a port.

You are very close. Try this instead:

make all-depends-list

That will recurse through all dependencies and print them for you. To test different build scenarios and how they affect the dependency list, try things like:

make NOPORTDOCS=yes NOPORTEXAMPLES=yes all-depends-list

make WITHOUT_X11=yes all-depends-list

Here is the full set of dependency print targets:

all-depends-list
build-depends-list
run-depends-list
package-depends-list
pretty-print-build-depends-list
pretty-print-run-depends-list

Cheers, Greg

To list ports on which depends:

pkg_info -rx "port-name"

To list ports which require :

pkg_info -Rx "port-name"
