One thing I’ve been using a lot lately is Madde’s mad-admin to add development packages to the build tree that QtSDK uses to build armel applications and I pretty much figured that out alone – well, not completely alone but after seeing a how-to related to qtmobility installation for Maemo that used this without really explaining what was what).<\/p>\n
Preamble:<\/p>\n
QtSdk comes with a full build environment (analogue to what one`s got on scratchbox) for armel applications. This is used every time you build a Qt project selecting a device (N9(|(0|5)0)). This whole mechanism stays quite hidden inside the sdk’s files.<\/p><\/blockquote>\n
Problem:<\/p>\n
Your application may have dependencies (headers, shared libs) on packages that are not provided with QtSDK. Without proper installation of this dependencies on QtSDK’s environment, you’ll never get code-completion, compiling or linking using the default SDK.<\/p><\/blockquote>\n
In a normal desktop-only world, you’d normally install development packages for a given library to then<\/em> be able to compile\/build applications that use such library. Only after installing those packages you’ll have the proper headers, shared libraries, etc needed to build your, “higher level”, application.<\/p>\n
Debian packages tagged by the -dev suffix usually carry what is needed (e.g. headers) for a developer to “develop” something that uses the homonimous library. While the package without<\/strong> the -dev suffix carry what is needed to RUN (e.g. shared library) an application that uses such package. (worth nothing that a foo-dev<\/strong> package will normally depend on the foo <\/strong>pkg).<\/p>\n
The question is: How to do this inside QtSDK’s own world.<\/p>\n
The secret (for Harmattan) is inside<\/p>\n
[sourcecode language=”shell”]
\n\/QtSDK\/Madde\/bin\/
\n[\/sourcecode]<\/p>\nPS: for maemo it’s inside<\/p>\n
[sourcecode language=”shell”]
\n~\/QtSDK\/Maemo\/4.6.2\/bin
\n[\/sourcecode]<\/p>\nbut works pretty much the same way.<\/p>\n
There you’ll find to binaries that make handling this libraries\/dependencies business as easy as on a normal debian system.<\/p>\n
Say you have a library called libfoo and that you already have it built and packaged for harmattan\/armel (well, that’s what I use Scratchbox for…but that stays for another post). You’ll probably have files like<\/p>\n
[sourcecode language=”shell”]
\nlibfoo_1.0_armel.deb
\nlibfoo-dev_1.0_armel.deb
\n[\/sourcecode]<\/p>\nWell, just do:<\/p>\n
[sourcecode language=”shell”]
\nyou@box:~\/QtSDK\/Madde\/bin$ .\/mad set harmattan-platform-api
\nyou@box:~\/QtSDK\/Madde\/bin$ .\/mad-admin xdpkg -i ..\/path-to-that-deb\/libfoo_1.0_armel.deb
\nPackage ‘libfoo’ installed.
\nyou@box:~\/QtSDK\/Madde\/bin$ .\/mad-admin xdpkg -i ..\/path-to-that-deb\/libfoo-dev_1.0_armel.deb
\nPackage ‘libfoo-dev’ installed.
\n[\/sourcecode]<\/p>\nIn line 1 you-re setting which target you are referring (you can select which target you are using in QtCreator’s project management window.
\nAfter that, on line 2 and 4 it’s pretty much the same thing as using dpkg -i. Voila! Now your QtCreator will recognize your new lib and all’s good.
\nRemember that you’ll need that foo_1.0_armel.deb package installed on the device but that should be automatic if you reference to it on your debian\/control file and if that package is in the same
\nrepository as your application.<\/p>\nWell, gotta go back to something useful.
\nHope this helps someone.<\/p>\n","protected":false},"excerpt":{"rendered":"One thing I’ve been using a lot lately is Madde’s mad-admin to add development packages to the build tree that QtSDK uses to build armel applications and I pretty much figured that out alone – well, not completely alone but after seeing a how-to related to qtmobility installation for Maemo that used this without really […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[13,14,19,15,18],"tags":[],"class_list":["post-45","post","type-post","status-publish","format-standard","hentry","category-harmattan","category-n9","category-n900","category-n950","category-qtsdk"],"_links":{"self":[{"href":"http:\/\/cpscotti.com\/blog\/index.php?rest_route=\/wp\/v2\/posts\/45","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/cpscotti.com\/blog\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/cpscotti.com\/blog\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/cpscotti.com\/blog\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/cpscotti.com\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=45"}],"version-history":[{"count":5,"href":"http:\/\/cpscotti.com\/blog\/index.php?rest_route=\/wp\/v2\/posts\/45\/revisions"}],"predecessor-version":[{"id":51,"href":"http:\/\/cpscotti.com\/blog\/index.php?rest_route=\/wp\/v2\/posts\/45\/revisions\/51"}],"wp:attachment":[{"href":"http:\/\/cpscotti.com\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=45"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/cpscotti.com\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=45"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/cpscotti.com\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=45"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
