-<title>Debugging Build Failures</title>

-<para>At the beginning of each phase of the build (such as unpacking,
-building or installing), the set of all shell variables is written to
-the file <filename>env-vars</filename> at the top-level build
-directory.  This is useful for debugging: it allows you to recreate
-the environment in which a build was performed.  For instance, if a
-build fails, then assuming you used the <option>-K</option> flag, you
-can go to the output directory and <quote>switch</quote> to the
-environment of the builder:
-
-<screen>
-$ nix-build -K ./foo.nix
-... fails, keeping build directory `/tmp/nix-1234-0'
-
-$ cd /tmp/nix-1234-0
-
-$ source env-vars
-
-<lineannotation>(edit some files...)</lineannotation>
-
-$ make
-
-<lineannotation>(execution continues with the same GCC, make, etc.)</lineannotation></screen>
