yes - I'm working on making that *really* easy. > Still, I have been browsing the MerSDK VM and I have questions. > (If I can get this more clear, I am willing to write some documentation for > other starters on Sailfish) > > Please confirm/correct. > > -code is and stays on the host machine; correct lets say it lives in <your home>/<path to src> The host machine src directory (actually all of 'home') is shared with the build engine.

(tbd since I'm writing that this weekend) > -rpm is installed on the SailFish VM. yes, QtC will copy the rpm over to the VM and install it Since you asked about install... :) There are actually 2 install modes; one just copies binaries and 'stuff' over to a private area on the emulator and runs from there. The other mode actually installs your rpm to 'proper' system locations. The first is mainly used for hack/build development cycles as it is faster. The second is used when you're ready to fully QA your app and ensure it installs and runs properly. > Thanks. > > r > > > On 04/17/2013 12:10 PM, David Greaves wrote: >> On 17/04/13 10:34, Wim de Vries wrote: >>> christopher.l...@thurweb.ch schreef op 2013-04-16 23:05: >>>> If so, what ends up (if anything) in the Sailfish SDK and Emulator VMs? >>> I am just concentrating on the MER SDK for now. >>> Building the QtSerialPort project goes without errors. >>> But I haven't yet found out where the libs and headers did end up. >>> (I am not very experienced on VMs: >>> due to the directory mapping between host and VM it's hard to determine >>> what is >>> living on which (virtual) machine) >>> Building pilotnavigator fails because QtSerial headers are not found. >> This is the problem >> >>>> Depending on this, you may or may not need to deploy something to one >>>> or both in order to build and run your pilotnavigator project which >>>> imports QtSerialPort. >>> Yes, but where and how can I deploy QtSerialport on both VMs? >> This points to the solution :) >> >> For those unsure about terminology: we say QtSerialPort is a >> dependency for pilotnavigator; it could be a runtime dependency (eg if it >> provides an application or service only used during execution) or it may >> also be >> a build-time dependency (eg if some C++ code needs header files). >> >> In order for Sailfish to resolve this dependency automatically, QtSerialPort >> needs to be packaged into an rpm and SailfishOS needs to be told where to >> get it >> from. >> >> So step 1 is to make and rpm of QtSerialPort, step 2 is to put it somewhere >> (a >> repository) where SailfishOS can retrieve it - either when building the >> pilotnavigator app or when a user installs it. >> >> Both of these steps are still being polished - they are both possible right >> now >> but they are more complicated than we want them to be. >> >> I'll get some instructions pulled together - if you want to start by yourself >> then look at the spec file for making rpms and find out about the merproject >> OBS >> for building/publishing them as a repo (#sailfishos irc channel may be a good >> start) >> >>>> But stepping back a bit: are you actually asking the right question? >> Sensible thing to ask but even if not, this is still an important thing to be >> able to do. >> >> David >> >>>> p.s how are the thermals in Holland?
