Bug #185
Updated by Sven Eckelmann over 8 years ago
Running @gen-compat-autoconf.sh@ generates a broken header file ("@compat-autoconf.h@"), because the first line contains the invalid characters @-n@. This causes the build to fail with following error:
<pre><code>compat-autoconf.h:1:1: error: expected identifier or '(' before '-' token</code></pre>
This error is possibly caused by "line 8":https://git.open-mesh.org/batman-adv.git/blob/5b3eab94367eb94b8cff8af053e3c7465374a818:/gen-compat-autoconf.sh#l8 8":https://www.open-mesh.org/projects/batman-adv/repository/revisions/master/entry/gen-compat-autoconf.sh#L8 in the @gen-compat-autoconf.sh@ script. This line does **not** invoke echo with the @-n@ parameter, instead it outputs @-n@ literally which is then included in the header file and causing the error.

Possible fix:
I think line 8 is redundant, because line 39 would create the file anyway. If you want an alternative (to be sure) I'd suggest to replace line 8 by '@touch "${TMP}"@'.
