<html><body><div style="color:#000; background-color:#fff; font-family:arial, helvetica, sans-serif;font-size:10pt">Hi,<br><br>Would it be possible to use qreal rather than double and
float for the Qt function calls and template instantiations of Qt
objects? This would completely solve the ARM compilation problems and
avoid the need for the LINUX distributions that support ARM to carry
around patch files. The decision to use qreal as float for ARM is a
decision made by the Qt developers. Therefore, there is some resistance
to patch Qt within the Debian camp. I can supply patch files, for
changes against 1.4.3,<br><br>Thanks and best regards,<br><br>Will<div><span></span></div><div><br></div> <div style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"> <div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"> <div dir="ltr"> <hr size="1"> <font face="Arial" size="2"> <b><span style="font-weight:bold;">From:</span></b> William Bell <whbell@btinternet.com><br> <b><span style="font-weight: bold;">To:</span></b> Scribus User Mailing List <scribus@lists.scribus.net> <br> <b><span style="font-weight: bold;">Sent:</span></b> Tuesday, 20 August 2013, 20:45<br> <b><span style="font-weight: bold;">Subject:</span></b> Re: [scribus] Compiling Scribus 1.4.3 on an ARM CPU (Debian Wheezy)<br> </font> </div> <div class="y_msg_container"><br><div id="yiv1151779154"><div><div style="color:#000;background-color:#fff;font-family:arial, helvetica, sans-serif;font-size:10pt;">Hi
