[SailfishDevel] Odd issues with SDK - shared libraries not recognized as such

Wed Apr 5 06:51:28 UTC 2017

Hi Martin,

thank you for the tip, it worked nicely! There were several other libraries
affected: boost-program-options, libtiff, and libjpeg-turbo to name in
addition to the ones I mentioned earlier.

As for using sdk-mode - I actually didn't find (relatively fast google
search) on what does it do. In all examples on how to build packages
manually, I could see "-m sdk-install" option given. So, if you can give me
URL with description or tell what does it do and whether I should omit it,
please do so.

Ideally, I don't want to mess with sb2, all I wanted to run was

mb2 -t SailfishOS-i486 -s package.spec build

which failed due to the configuration error. Taking into account this bug,
maybe all packages specified in spec files as build-dep should be installed
in addition by zypper outside sb2?

Best wishes,

Rinigus
