c++ - Library dependencies when distributing software on Linux? -


i'm trying linux release piece of qt software, i'm clueless linux newbie. i've built application qt libraries statically linked, , made .deb , .rpm packages, when test them warnings missing libraries on distributions. example, .deb version runs fine on debian , ubuntu, doesn't start on linux mint kde due missing libraries. running ldd find there 4 missing libraries:

libpng16.so.16 => not found libicui18n.so.57 => not found libicuuc.so.57 => not found libicudata.so.57 => not found

clearly need somehow ensure necessary library present, list of libraries required seems vary. example linux mint cinnamon lists 33 libraries, while ubuntu unity lists 34 (libpng12.so.0 one). assume of libraries standard linux libraries come distributions wouldn't need include them.

i don't know i'm doing, few questions:

what best way determine list of libraries need include .deb , .rpm packages? if ldd best option, need include listed libraries or there bundled standard debian/rpm distributions?

what best way to include libraries? include them in package or specify them in dependency list?

any other general advice appreciated because i'm not sure i'm going right way.

thanks.

don't think library dependencies; think package dependencies.

when create (deb, rpm) package, can list other packages depends on. figure out package has desired library in it, , add package dependency.

then, when user installs package, package manager also, if needs to, install packages depends on. presto: have libraries need.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
