I'd like to compile Nginx 1.9.8 from source and install it on a Ubuntu 14.04 server. However, and this goes for any software, how do I figure out which dependencies I need to install on my local system in order to build the software?

Say I'd like to compile Nginx. I can always do aptitude show nginx to get dependencies for the current package available through a repository. On the other hand, this may not be a correct list as the repository may offer an old version where dependencies are different from the new version I'd like to compile.

In general, how do I collect the list of dependencies I need to have installed on a system for a given piece of software?

Given that the dependencies may differ based on the compilation options I provide, is this a matter of "trial and error". That is, should I attempt to compile, then wait for the first error, see what it complains about, add that dependency, and do the same iteration again?

if you are lucky enough to have the software in your repositories, you can install dependencies with apt:

root # apt-get build-dep nginx 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Note, selecting 'libgd-dev' instead of 'libgd2-dev'
Note, selecting 'liblua5.1-0-dev' instead of 'liblua5.1-dev'
The following NEW packages will be installed:
  autotools-dev debhelper dh-apparmor dh-systemd geoip-bin gettext
  intltool-debian libcroco3 libfontconfig1-dev libfreetype6-dev libgd-dev
  libgeoip-dev libice-dev libice6 libjbig-dev libjpeg-dev libjpeg-turbo8-dev
  libjpeg8-dev liblua5.1-0 liblua5.1-0-dev liblzma-dev libmhash-dev libmhash2
  libpam0g-dev libpcre3-dev libpcrecpp0 libperl-dev libpng12-dev
  libpthread-stubs0-dev libreadline-dev libreadline6-dev libsm-dev libsm6
  libtiff5-dev libtiffxx5 libtinfo-dev libunistring0 libvpx-dev libx11-dev
  libxau-dev libxcb1-dev libxdmcp-dev libxml2-dev libxpm-dev libxslt1-dev
  libxt-dev libxt6 pkg-config po-debconf x11-common x11proto-core-dev

  • But then again, what if the nginx in my repositories is a different version from the one I'd like to install? I can't be sure the dependencies have not changed.

  • most of the times, small version changes do compile with same deps. I don't think there is a way to determine dependencies for an arbitary version

  • Alright...so if I try to compile a piece of software which is not in any repository, it's a matter of some detective work then to figure out dependencies...

    Yes. That's what package maintainers do. Typically, reading the docs will give some reasonable hints.

  • if it's not in any ppa with source listings, then yes
