# Configuring a build directory |
|
|
|
Often you want to change the settings of your build after it has been |
|
generated. For example you might want to change from a debug build |
|
into a release build, set custom compiler flags, change the build |
|
options provided in your `meson_options.txt` file and so on. |
|
|
|
The main tool for this is the `meson configure` command. |
|
|
|
You invoke `meson configure` by giving it the location of your build |
|
dir. If omitted, the current working directory is used instead. Here's |
|
a sample output for a simple project. |
|
|
|
Core properties |
|
|
|
Source dir /home/jpakkane/clangdemo/2_address |
|
Build dir /home/jpakkane/clangdemo/2_address/buildmeson |
|

Project options: |
|
Option Current Value Possible Values Description |
|

|
array_opt [one, two] [one, two, three] array_opt |
|
combo_opt three [one, two, three] combo_opt |

Testing options: |
|
Option Current Value Possible Values Description |
|
------ ------------- --------------- ----------- |
|
errorlogs true [true, false] Whether to print the logs from failing tests |
|
stdsplit true [true, false] Split stdout and stderr in test logs |
|
|
|
These are all the options available for the current project arranged |
|
into related groups. The first column in every field is the name of |
|
the option. To set an option you use the `-D` option. For example, |
|
changing the installation prefix from `/usr/local` to `/tmp/testroot` |
|
you would issue the following command. |
|
|
|
meson configure -Dprefix=/tmp/testroot |
|
|
|
Then you would run your build command (usually `meson compile`), which |
|
would cause Meson to detect that the build setup has changed and do |
|
all the work required to bring your build tree up to date. |
|
|
|
Since 0.50.0, it is also possible to get a list of all build options |
|
by invoking [`meson configure`](Commands.md#configure) with the |
|
project source directory or the path to the root `meson.build`. In |
|
this case, Meson will print the default values of all options similar |
|
to the example output from above.
