java - Substitutes for unix shell commands for windows? -


i developing source code judging software.i have developed on linux platfrom ubuntu 12.04 lts.

now want deploy on windows. software creating commands per unix shell,saving them in file , executing commands through file. here part of code:

package codejudge.compiler.languages;  import java.io.bufferedwriter; import java.io.filenotfoundexception; import java.io.fileoutputstream; import java.io.ioexception; import java.io.outputstreamwriter;  import codejudge.compiler.timedshell;  public class c extends language {      string file, contents, dir;     int timeout;      public c(string file, int timeout, string contents, string dir) {         this.file = file;         this.timeout = timeout;         this.contents = contents;         this.dir = dir;     }     public void compile() {         try {             bufferedwriter out = new bufferedwriter(new outputstreamwriter(new fileoutputstream(dir + "/" + file)));             out.write(contents);             out.close();             // create compiler script             out = new bufferedwriter(new outputstreamwriter(new fileoutputstream(dir + "/compile.sh")));             out.write("cd \"" + dir +"\"\n");             out.write("gcc -lm " + file + " 2> err.txt");             out.close();             runtime r = runtime.getruntime();             process p = r.exec( dir + "/compile.sh");             p.waitfor();             p = r.exec(dir + "/compile.sh"); // execute compiler script             timedshell shell = new timedshell(this, p, timeout);             shell.start();             p.waitfor();         } catch (filenotfoundexception e) {             e.printstacktrace();         } catch (ioexception e) {             e.printstacktrace();         } catch (interruptedexception e) {             e.printstacktrace();         }     }      public void execute() {         try {             // create execution script             bufferedwriter out = new bufferedwriter(new outputstreamwriter(new fileoutputstream(dir + "/run.sh")));             out.write("cd \"" + dir +"\"\n");              out.write("./a.out < in.txt > out.txt");             out.close();             runtime r = runtime.getruntime();             process p = r.exec(dir + "/run.sh");             p.waitfor();             p = r.exec(dir + "/run.sh"); // execute script             timedshell shell = new timedshell(this, p, 3000);             shell.start();             p.waitfor();                     } catch (filenotfoundexception e) {             e.printstacktrace();         } catch (ioexception e) {             e.printstacktrace();         } catch (interruptedexception e) {             e.printstacktrace();         }     } }

when running same code on windows getting following erros( ihave mingw installed on windows):

codejudge compilation server running ... compiling garima.c... java.io.ioexception: cannot run program "c:\xampp\htdocs\project\codejudge-compiler\stage\1/compile.sh": createprocess error=193, %1 not valid win32 application     @ java.lang.processbuilder.start(unknown source)     @ java.lang.runtime.exec(unknown source)     @ java.lang.runtime.exec(unknown source)     @ java.lang.runtime.exec(unknown source)     @ codejudge.compiler.languages.c.compile(c.java:41)     @ codejudge.compiler.requestthread.run(requestthread.java:65) caused by: java.io.ioexception: createprocess error=193, %1 not valid win32 application     @ java.lang.processimpl.create(native method)     @ java.lang.processimpl.<init>(unknown source)     @ java.lang.processimpl.start(unknown source)     ... 6 more java.io.filenotfoundexception: c:\xampp\htdocs\project\codejudge-compiler\stage\1\err.txt (the system cannot find file specified)     @ java.io.fileinputstream.open(native method)     @ java.io.fileinputstream.<init>(unknown source)     @ java.io.fileinputstream.<init>(unknown source)     @ codejudge.compiler.requestthread.compileerrors(requestthread.java:90)     @ codejudge.compiler.requestthread.run(requestthread.java:66) java.io.ioexception: cannot run program "c:\xampp\htdocs\project\codejudge-compiler\stage\1/run.sh": createprocess error=193, %1 not valid win32 application     @ java.lang.processbuilder.start(unknown source)     @ java.lang.runtime.exec(unknown source)     @ java.lang.runtime.exec(unknown source)     @ java.lang.runtime.exec(unknown source)     @ codejudge.compiler.languages.c.execute(c.java:65)     @ codejudge.compiler.requestthread.run(requestthread.java:72) caused by: java.io.ioexception: createprocess error=193, %1 not valid win32 application     @ java.lang.processimpl.create(native method)     @ java.lang.processimpl.<init>(unknown source)     @ java.lang.processimpl.start(unknown source)     ... 6 more java.io.filenotfoundexception: c:\xampp\htdocs\project\codejudge-compiler\stage\1\out.txt (the system cannot find file specified)     @ java.io.fileinputstream.open(native method)     @ java.io.fileinputstream.<init>(unknown source)     @ java.io.fileinputstream.<init>(unknown source)     @ codejudge.compiler.requestthread.execmsg(requestthread.java:106)     @ codejudge.compiler.requestthread.run(requestthread.java:77)

i have little knowledge of win32 shell commands..what changes required made code ie. commands should changed not run on windows? , substittes windows?

you can use gnuwin32 tasks.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
