<p>Hi,</p>
<p><br>
</p>
<p>We have situation when MACHINE value change affect nativesdk packages (thud but the same situation was on krogoth).<br>
<br>
MACHINE="x86" bitbake nativesdk-<package> -> build package and dependencies x86<br>
MACHINE="x86-64" bitbake nativesdk-<package> -> build package and dependencies for x86-64<br>
and finally<br>
MACHINE="x86" bitbake nativesdk-<cpackage> -> a lot of setscene functons executed for nativesdk packages<br>
<br>
MACHINE value affects BASELIB. For x86-64 we override BASELIB = lib64.<br>
For x86 BASELIB = lib. baselib for cross/natviesdk ramains unchanged (lib).<br>
<br>
<span style="font-family:"Courier New",monospace"># $BASELIB</span><br style="font-family:"Courier New",monospace">

<br>
Tracking dependencies shows that nativesdk-<package> depends on gcc-crosssdk which depend on<br>
shared gcc-source package. And gcc-source tasks hash values (starting from from gcc-source.do_patch) are different for<br>
x86 and x86-64 (due to baselib), so nativesdk-<package> task stamp signature deps part depends on gcc-source tasks hash
</p>
<p>and also become different if we change MACHINE.<br>
</p>
<p><br>
</p>
<p>Technically it can be fixed with tweaking sstate_rundepfilter - but it's not generic solution.<br>
</p>
<p><br>
Is there any way to avoid rebuilding nativesdk packages that depend on shared packages (e.g. gcc-source)?</p>
<p><br>
