<div dir="ltr">Hi all, My machine is running on 2.6.25.10-86.fc9.i686. When I tried to compile an open source, following errors displayed. [error on the screen] /usr/bin/m4:<a href="http://condigure.ac:1240">condigure.ac:1240</a>: recursion limit of 1024 execcded, use -L<N> to change it autom4te: /usr/bin/m4 failed with exit status: 1 autoscan: /usr/bin/autom4te failed with exit status: 1 [end of the error] The results of the autoscan are attached. I think that the problem can be resolved by m4 -L2048. When I execute autoscan. it invokes autom4te after that invokes 'Autom4te::Request'. The Autom4te::Request is 'Request.pm' that is Perl module. How can I change default option of nesting-limit from 1024 to 2048 for m4 ? Thanks in advance. regards, </div>
