<![CDATA[How to make Qt Creator stop compiling after the first error]]>I often make a small error which leads to a lot of other errors, so the program won't compile. But to fix my error, I only need to know the first error, not the other ones. For example, imagine I write the following code:

intt x = 0;
int y = x;
return x + y;

In this case, to fix the error, I only need to know that I wrote intt instead of int, but Qt Creator would continue compiling after the first line putting an error on the second line and the third line saying that x is undefined. In this case it doesn't matter so much, but in real life, I would use x over 100 times and Qt Creator would take several minutes to compile a code although it already knows that it won't succeed to compile.

So my question is, is there a way to make Qt Creator stop compiling after the first error?

A "sub-project" meant run a new make recursively from the makefile. If a compilation fails that returns a non-0 result to its make which then exits immediately returning non-0 to its parent make. You then have the - symbol in a makefile command and/or the -k argument to make for further control.

Worked, and worked fine, for a century. Why do they need to complicate stuff? ;-)

In another one it will stop the current project too I'm sure :)

The compiler it uses is MSVC. Unfortunately it has no such option. There was a feature request for it on Microsoft's UserVoice site, but it was closed due to little interest.

GCC (and MinGW) on the other hand has a switch for it that you can pass to the compiler in the .pro file: QMAKE_CXXFLAGS += -Wfatal-errors.
So if you want that feature in MSVC you'll need to convince Microsoft to implement it :(

Therefore you have to see whether the compiler you're using supports the feature you want. If this can be enabled via a compiler option, then it can be added to the .pro file using QtCreator.
