Discussion:
[Bug-apl] why no difference between configure --help=short and --help=recursive

Wanting to understand my ./configure options, for SVN 927,
I did ./configure --help, ./configure --help=short, and ./configure --help=recursive.
Captured the output from all 3 and then did a diff on the logs of the short vs the recursive.
There is no difference other than the values of --help.

Did I do something wrong?

<br>
you are not doing anything wrong.<br>
<br>
The different <b>--help</b> variants in the <b>configure</b>
script are generated by the <b>autoconf</b> tool itself. Whether
they<br>
make a difference or not probably depends on how the macros
provided by <b>autoconf</b> are being used by<br>
<b>configure.ac</b><br>
<br>
From an <b>autoconf</b> perspective GNU APL is probably a small
project because it produces essentially only one<br>
binary. Therefore the <b>configure</b> options are flat and so is
the help for them. I suppose that in a project that<br>
produces, for example, multiple binaries, there might be per
binary configure options. But for GNU APL this<br>
is simply not the case.<br>
