I need to compile some software on my Fedora machine. Where's the best place to put it so not to interfere with the packaged software?

Rule of thumb, at least on Debian-flavoured systems:

  • /usr/local for stuff which is "system-wide"—i.e. /usr/local tends to be in a distro's default $PATH, and follows a standard UNIX directory hierarchy with /usr/local/bin, /usr/local/lib, etc.

  • /opt for stuff you don't trust to make system-wide, with per-app prefixes—i.e. /opt/firefox-3.6.8, /opt/mono-2.6.7, and so on. Stuff in here requires more careful management, but is also less likely to break your system—and is easier to remove since you just delete the folder and it's gone.

  • interestingly, many programs/appplications automatically suggest to install to /opt if you do sudo install.

  • I would also recommend puting your source code in a subdirectory ie /usr/local/src. Cf unix.stackexchange.com/a/362784/78577 and refspecs.linuxfoundation.org/FHS_3.0/…

    Please, please stop using this extremely bad system. Just put it in your user dir, in something with a normal, sensible name like ~/apps and then either symlink binaries into a $PATHed directory or add them as aliases to your shell config. The world of computers has enough dumb complexity as it is.

If you really don't want it to interfere at all, don't put it anywhere in your $PATH.

If you want it in $PATH, at least make sure not to install to /usr/local. I've found that a lot of software looks there even if it's installed by the distro into /usr.

My favorite way to install custom-compiled software is in my $HOME directory. That way you don't have to use sudo for anything, and it's very nicely separated from the rest of your system. For example:

mkdir ~/stage
./configure --prefix=/home/username/stage && make && make install

And if you want to, you can then add /home/username/stage/bin to your $PATH.

    Definitely, using your home directory is the best option. IMO.

    +1 Agreed. I like ~/sbin for bash/ruby/python scripts, and ~/opt/... for compiled installs, with aliases in ~/bin.

    +1 for using your home directory as it makes things simpler; -1 for the suggestion to avoid $PATH -- there are actually directories there "reserved for local installs" according to the standards (e.g., /usr/local).

    My suggestion to avoid /usr/local was based on the original poster's (somewhat vague) desire to not interfere with packaged software. Since there is plenty of packaged software that will "help" by looking in /usr/local or in $PATH, I figured that qualifies as interfering. But it really depends on a person's individual needs and goals. /usr/local can be a perfectly fine choice in many situations.

FHS says to put it in /usr/local where distributions shouldn't be touching it. /usr/local/bin for the binaries /usr/local/src for the source and /usr/local/lib for libraries. See the FHS spec for more info

  • What about configuration? Say I installed MySQL without using the package manager, should I still use /etc/mysql for the configuration?

Most of the time, I like to place my own compiled stuff in /opt. It's sort of a pseudo-standard place. You can also consider /usr/local, but I prefer to keep my stuff 100% isolated.

    distro's tend to put quite a few things in /opt (usually proprietary packages) /opt doesn't say that the distro can't touch it. however it does say that about /usr/local

    I've never seen a distro put stuff in /opt, however I've seen many times where /usr/local is littered with junk that does come from the distro

  • distro's I use like to put java in /opt I've seen acrobat reader in there too. if they are putting stuff in /usr/local they are ignore FHS which say it needs to be safe from being overwritten in system updates.

  • To each their own, I guess. FHS is nice, but I think it gets ignored sometimes.

  • The only stuff I've ever seen distro packages place in /usr/local was directory hierarchies that paralleled those in the standard tree, and maybe index files for things like TeX.

Put them to /usr/local/src.

What I do is extract the source in this directory. It will create a path like

/usr/local/src/postgresql-8.3.7

Then I create a symbolic link to it:

/usr/local/src # ln -s  postgresql-8.3.7 postgresql

Do all your building in /usr/local/src/postgresql.

Doing things this way helps when you need to pop between versions and documents what version you are using.

Per the FHS, /usr/local/ is used for applications compiled from source, while /opt/ is used for 3rd party applications not supported by your operating system vendor.

If there is possibility - I'd suggest compiling your software and then creating FC package (I believe it's using yum to install software packages). Then you can install that package of your own compiled software and remove it without messing up the whole system.

If you want to able to easily install and remove several applications you've built yourself, you can use Stow as a simple package manager.

Two things I'd recommend:

System wide: use stow and install under /usr/local/stow/package-version. Then you can easily switch between version.

In my home, or if I don't have /usr/local write permissions, I personally install programs under ~/.local, which is hinted by XDG standard.

You can also use stow locally, although I never did :)

I have a little different setup than most people because I do a lot of development. I have a /home/jackson/bin/ directory that I install stuff into and I've edited my .bashrc adding this:

export PATH=/home/jackson/bin/bin::$PATH
export LD_LIBRARY_PATH=/home/jackson/bin/lib:$LD_LIBRARY_PATH
export PKG_CONFIG_PATH=/home/jackson/bin/lib/pkgconfig:$PKG_CONFIG_PATH

I wouldn't do this for everything, but its nice during development.

It is actually not that hard to create deb's or rpm's from a source tarball. That way, you can use the facilities of your distro's package manager to keep your system clean. This is what I do, most of the time: just create a little rpm.

if you are compiling an application you can add its executables path in you PATH env variable. this will not impact other users.

There's always the option to "put it where it belongs" but write a simple rpm, first.

If you want your application to be available for all users on the system and you have the necessary permissions, use /opt. If you want the application to be available only for you (and root), use /home/username

The easiest way of doing this is to grab the source package (.src.rpm for RPMites), unpack it, hack the new source/configuration/whatever into it, change the version appropiately and build. Installing this makes your package manager aware of the new package, allows to consider it for dependencies and uninstall/update.

This is a chore the first time around, but if a new version (or some critical patch) comes out, it is then simpler to update. Another benefit is that you can create your own repository with local software, to be shared e.g. by the machines in a lab.

Write an RPM, it is not difficult, has guidelines on where to put things and makes uninstalling a snap.

If you do this, install files under /usr and not under /usr/local, like all other files that come through the packaging system.
