code generation - qt qmake extra compilers with dependencies among generated files -

-

can qmake handle dependencies of generated source files?

we have prf file this:

idl_h.name = generate .h file ${qmake_file_base}.idl idl_h.input = idls  # variable containing our input files idl_h.variable_out = headers idl_h.commands = <command takes .idl , genrates .h> idl_h.output = $$idl_gen_dir/${qmake_file_base}.h qmake_extra_compilers += idl_h

this generation works fine , creates .h files @ make time. problem input files ($$idls) depend on each other, , not built in correct order. have app.idl, containing:

#include "common.idl"

it seems following should work

idl_h.depend_command = g++ -ee ... $$idl_gen_dir/${qmake_file_base}.h

but apparently depend_command is not executed.

another idea parse dependencies out of original idl:

idl_h.depends = $$system(cat ${qmake_file_in} | grep "^#include" | sed -re 's/#include\s+["<]([^.]+)\.idl[">]/\1.h/')

but seems qmake syntax failing me.

try adding

idl_h.dependency_type = type_c

to prf, , drop .depend_command , .depends

c++ - Convert big endian to little endian when reading from a binary file -

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...

C#: Application without a window or taskbar item (background app) that can still use Console.WriteLine() -

i'm trying create application adheres following: no taskbar no console or form window can utilize console.writeline() . (i.e. if executes app command prompt write console.) the problem if create windows form (or wpf) application can have there no taskbar, console or window show up, console.writeline() nothing. if create console app, writes console, can't figure out how hide (and if did hide it, write command prompt window?)... how do this? just create standard console application. callers responsibility hide window caused program (from how run c# console application console hidden ): system.diagnostics.processstartinfo start = new system.diagnostics.processstartinfo(); start.filename = dir + @"\myprocesstostart.exe"; start.windowstyle = system.diagnostics.processwindowstyle.hidden;
