System function doesn't work anymore after deploy

RekTek249

Hey, I'm using curl. I have the following code been used to send an email:

QString cmd = "curl smtp://smtp.gmail.com:587 -v --mail-from \"xxxxxxxxxx@gmail.com\" --mail-rcpt \"xxxxxxxxx@gmail.com\" --ssl -u xxxxxxxxxxx@gmail.com:xxxxxxxxxxxxxx-T \"msg.txt\" -k --anyauth";
const char* ccmd = cmd.toStdString().c_str();
WinExec(ccmd, SW_HIDE);

It works fine in Qt Creator Debug but when I "Deploy" it, it doesn't work anymore. Here is how I deployed it. { Qt Console >> cd <MyPathToMyProject> >> windeployqt --gui . } Thanks for your help...

@RekTek249 ,

May be some dll's and libraries will be missing.

make sure curl have all needed dlls also.

Why using WinExec rather than QProcess? but, most importantly, why using curl.exe rather than the libcurl API?

@VRonin Because I didn't find any code for libcurl in c++... And I'm using WinExec because I had no idea QProcess existed. I'll google that and try replacing it with that... @Vinod-Kuntoji @mrjj I use the same that in debug, it should work...

It's literally on libcurl's website: https://curl.haxx.se/libcurl/bindings.html

Hi

I use the same that in debug, it should work...

When you run the app in Creator (both release/debug) it has a runtime environment setup including paths for dlls etc.

When you run it outside in a folder, its not setup same way.

You could use
http://www.dependencywalker.com/
to see if any is listed as missing.
I would examine the curl.exe first to see what it needs.

windeployqt cannot know if curls need anything to run as its external app.

const char* ccmd = cmd.toStdString().c_str();

One note: why do you create a QString first and then a char*? The QString in this case isn't needed, just do:

char* cmd = "curl smtp://smtp.gmail.com:587 -v --mail-from \"xxxxxxxxxx@gmail.com\" --mail-rcpt \"xxxxxxxxx@gmail.com\" --ssl -u xxxxxxxxxxx@gmail.com:xxxxxxxxxxxxxx-T \"msg.txt\" -k --anyauth";
