[elbe-devel] pbuilder on wheezy targets: incompatible "-jauto" option

[Manuel Traut]

Hi Lukasz,

thanks for your report. I opened an issue:
https://github.com/Linutronix/elbe/issues/147

> When building Debian packages for <suite>wheezy</suite> images with pbuilder, elbe calls pdebuild with --debbuildopts "-jauto", which is supported by dpkg since version 1.17.10:
> 
> 
> dpkg-buildpackage(1):

>       -j, --jobs[=jobs|auto]
>               Number  of  jobs  allowed  to  be  run  simultaneously,  number  of  jobs matching the number of online
>               processors if auto is specified (since dpkg 1.17.10), or unlimited number if  jobs  is  not  specified,
> 
> 
> However, pbuilder for a <suite>wheezy</suite> image is (not surprisingly) created as Debian 7.x (wheezy) pbuilder:
