problem with static building

[mismael85]

hi,
i built a simple GUI that uses another console application.and i embeded this console application in my GUI exe file using resources.and i built the program using shared linking and the program worked fine.but when i built my program using static linking , the program runs well but when it tries to run the console app, it failes.
what is the problem?

Read your post and then think about how we should help you with this few informations.

i used this xml code to add the console app into my resource file

<file>Resources/upx.exe</file>
and i used this code to access the program

UPX = new QProcess(this);
UPX->start("./Resources/upx.exe", QStringList(QDir::toNativeSeparators(lineEdit->text())));
note that this code works fine when it is built shared.
it only does not work when it built static.
i mean by work that my program works but when i execute the last code it do nothing. it means the program doesn not see the console app.
i hope that is enough.

First of all, you can't execute an executable which has been embedded as a resource. You would have to extract it first. Secondly, start("./Resources/upx.exe") does not even run it from resources but from a sub-directory called similarly.

[mismael85]

you are right.
i tried the shared version a way from the UPX.exe file and it did not work.
so how can i extracte it?

so how can i extracte it?
I'd simply try with QFile::copy() from resources to disk. This way the OS has chances to actually execute it.

i used this code

QFile::copy("./resources/upx.exe", "c:\\")
but nothing copied in the c: directory.

I thought it was "./Resources/upx.exe" not "./resources/upx.exe" and the second parameter takes the new name even if it remains the same, not just the target path.


if (QFile::copy(":/Resources/upx.exe", "c:/upx.exe"))
{
...
}

and still "./resources/upx.exe" isn't a resource path...

Oops, my bad. Thanks for pointing it out. ;)

[mismael85]

what is the difference between using

./Resources/upx.exe
and using

:/Resources/upx.exe
