Build Targets
=============
When you build with ``mach build``, there are some special targets that can be
built. This page attempts to document them.
Partial Tree Targets
====================
The targets in this section only build part of the tree. Please note that
partial tree builds can be unreliable. Use at your own risk.
export
Build the *export* tier. The *export* tier builds everything that is
required for C/C++ compilation. It stages all header files, processes
IDLs, etc.
compile
Build the *compile* tier. The *compile* tier compiles all C/C++ files.
libs
Build the *libs* tier. The *libs* tier performs linking and performs
most build steps which aren't related to compilation.
tools
Build the *tools* tier. The *tools* tier mostly deals with supplementary
tools and compiled tests. It will link tools against libXUL, including
compiled test binaries.
binaries:
Recompiles and relinks C/C++ files. Only works after a complete normal
build, but allows for much faster rebuilds of C/C++ code. For performance
reasons, however, it skips nss, nspr, icu and ffi. This is targeted to
improve local developer workflow when touching C/C++ code.
install-manifests
Process install manifests. Install manifests handle the installation of
files into the object directory.
Unless ``NO_REMOVE=1`` is defined in the environment, files not accounted
in the install manifests will be deleted from the object directory.
install-tests
Processes the tests install manifest.
Common Actions
==============
The targets in this section correspond to common build-related actions. Many
of the actions in this section are effectively frontends to shell scripts.
These actions will likely all be replaced by mach commands someday.
buildsymbols
Create a symbols archive for the current build.
This must be performed after a successful build.
check
Run build system tests.
