Where can I find the source of Nautilus? I'd like to play around with its source code and compile it. What's the best way to go about this? Obviously, it would be nice if I would easily be able to revert to the repository version if something bad happens 🙂
Installation instructions vary across programs although there are well-established tools like autotools (includes automake and autoconf) and cmake.
Since programs can come in different programming languages, its hard to give generic commands that suit all packages. For example, Python often have setup.py scripts where C programs often use autotools or at least a Makefile.
I always start with finding the INSTALL, README or similar files. If you need to compile a program from source, you likely need the
build-essential package which depends on compilers and other generic development packages.
Depending on the program you're trying to compile, you might need to install other dependencies. Check the README for that or the output of the
./configure script (an executable file located in the root of the extracted source). For example, if it says that you need "x11 development headers", try finding "x11-dev" or "libx11-dev" in the repositories (in this case, it's
libx11-dev what you're looking for).
Source distributions that were built with autoconf/automake can be extracted and configured with:
tar xf foo-1.0.tar.gz
sudo make install
./configure --help for available options. By default, the files are often installed to
/usr/local which is perfectly fine. Unless you're going to package the file into a .deb file, do not change this prefix to
/usr as it may conflict with the package management system (dpkg).
make is supposed to start compiling everything where
make install installs the files to the designated locations (
sudo is necessary for writing to privileged locations like
/usr/local). To uninstall it later, run from the source directory
sudo make uninstall (providing that the package is properly build with autoconf/automake, which is a responsibility of the developer, not you, the user!
If you're just interested in compiling a package from the software center on your computer, proceed with (replace
package and the version accordingly):
sudo apt-get build-dep package
apt-get source package
dpkg-buildpackage -b -uc -us
See the respecxtive manual pages for more details on the commands. (e.g. run
man dpkg-buildpackage in a terminal). After performing these commands, you'll have a .deb file in the parent directory. It's recommended to use the packages from Ubuntu repositories where possible. The above steps are shown for educational reasons, but generally you want to make a modification to some files before building the package.
The install notes, referenced in the README text of the nautilus 3.8 version source-code. It lists dependencies, and gives installation instructions.
You may want to read the README file in the source code folder.
