The test suite must be run separately from the build, either before or
|
|
after the package is built and installed. Do not run
|
|
<command>make install</command> after running the test suite. To build
|
|
and install the package, you need to start with a fresh or clean source
|
|
tree. For the test, you also need a clean source code, so either start by
|
|
removing the source code directory and starting over, by uncompressing
|
|
the source tarball or by running <command>make clean</command>. Then
|
|
configure again, adding <quote>--with-pydebug</quote> to the
|
|
<command>configure</command> switches above, run <command>make</command>,
|
|
then <command>make test</command>. Remember that tests must be executed
|
|
using an X terminal. One test fails. The test SBU highly depends on the
|
|
speed of the internet connection.
