<div> </div>
<div>For a while now I have been trying to run GiNaC with CLN on an IPhone. To achieve that goal I need my Library Build to support some different architectures. So I used this handy bash script to get what I want:</div>
<div> </div>
<div>
<div><span style="font-size:12px;"><span style="font-family:courier new,courier,monospace;">#!/bin/bash</span></span></div>

{<br/>
sdks=`ls $PLATFORMPATH/$1.platform/Developer/SDKs`<br/>
arr=()<br/>
for sdk in $sdks<br/>
do<br/>
arr[${#arr[@]}]=$sdk<br/>
done</span></span></div>
<div><span style="font-size:12px;"><span style="font-family:courier new,courier,monospace;"> # Last item will be the current SDK, since it is alpha ordered<br/>
count=${#arr[@]}<br/>
if [ $count -gt 0 ]; then<br/>
sdk=${arr[$count-1]:${#1}}<br/>
num=`expr ${#sdk}-4`<br/>
SDKVERSION=${sdk:0:$num}<br/>
else<br/>
SDKVERSION="10.1"<br/>
fi<br/>
}</span></span></div>

<div> </div>
<div>I customised this a bit for GiNaC whih mainly ment swapping the last line with:</div>
<div> </div>
<div><span style="font-size:12px;"><span style="font-family:courier new,courier,monospace;">lipo -create ./output/armv7/lib/libginac.a ./output/armv7s/lib/libginac.a ./output/arm64/lib/libginac.a ./output/x86_64/lib/libginac.a ./output/i386/lib/libginac.a -output libginac.a</span></span></div>
<div> </div>
<div>The reason for this causes me to post here. After the build I can not seem to find any output in the arm64, armv7 and armv7s folders. GiNaC has output in all of those folders. Is it not possible to build CLN for those archs ?</div>
<div> </div>
<div><span style="font-family:verdana,geneva,sans-serif;"><span style="font-size:12px;">Also here is my full error message from the linker:</span></span></div>
