Hello friends,<br><br>As far as I have been investigating this problem, seems that GNU compilers have a problem when combining -c flag with multiple files and -o flag to generate an executable.<br><br>The problem is that CMake somehow is generating the compile command, and assembling it wrongly. Is there any way to overcome this issue?<br>
<br>Thanks<br><br>Best Regards<br><br>Enrique<br><br><br><br><div class="gmail_quote">On Wed, Mar 2, 2011 at 10:51 AM, Enrique Izaguirre <span dir="ltr"><<a href="mailto:enrique.izaguirre@gmail.com">enrique.izaguirre@gmail.com</a>></span> wrote:<br>
