#935 OSX: QProcess killed during compilation

[Anonymous]

I have the following problem:

I have a rather large tex file to compile, including pgfplots, which take a while to compile, when using no externalize function. I switched from Windows with Miktex to a Mac with TexLive. When I start the compilation with

/usr/texbin/pdflatex -shell-escape -output-directory=build -synctex=1 -interaction=nonstopmode %.tex

it works fine. When I start the compilation within Texstudio (F1), it compiles, when I comment parts of the file, no matter which one it is. However, when the compilation takes too long (mostly after exactly 30s), the compilation crashes, leaving the .aux and the .log unfinished, but without any error message. When I start texstudio from the command line and compile with F1, the error

QProcess: Destroyed while process ("/usr/texbin/pdflatex") is still running.

is printed in the terminal. Some research brought me to the function waitForFinished(), which apparently has a timeout after 30s. Searching for that function in the texstudio folder with grep gave no result.

Has anyone of you got a clue why this is happening and how to stop it? I don't give a minimum working example, since the file compiles alright in the terminal and also from texstudio, when commenting some part of it, no matter which.

Since I found no other way to upload an example, I re-submitted the the ticket.

Where did you define the command? As user or quickbuild command?

It does not seem to consider it a latex command. (as is does for "pdflatex" or "compile"). The names of all latex commands are listed in the texstudio.ini under the Tools\Kind\LaTeX key

[Jakob]

I use F1, so quick build and view, which is defined as

txs:///compile | txs:///bibtex | txs:///view

where the standard compiler is

txs:///pdflatex

and the command for that is

/usr/texbin/pdflatex -shell-escape -output-directory=build -synctex=1 -interaction=nonstopmode %.tex

To be honest, I don't quite get what you mean by "it does not considere a latex command". It compiles alright, when the tex file is short enough (in terms of compilation time). Just if there are too many 3D pgf, which need to be recompiled, it chrashes, even though it works for each one individually.

[Benito van der Zander]

That looks all correct

What does it list in texstudio.ini in the Tools\Kind\LaTeX key?

Can you compile it from source to test some stuff?

it does not considere a latex command".

If you call a latex command, it waits till the command has stopped and shows the log afterwards

If you call a non-latex command, it kills it after 30s

[Jakob]

I would love to do so, but compilation fails. Any ideas on that:

TeXstudio compilation :

Darwin
-n Enter SYSTEM (1: UNIX ; 2: MACOSX)
(default is 2) :

-n Enter path to QT4 (e.g. /usr/lib/qt4, you can leave it empty if qmake is in PATH)
(default is /usr/local) :

-n Do you want to use the internal pdf viewer (requires the Poppler library)? (yes/no)
(default is yes) :

-n Do you want to use the video player in pdf files (requires the Phonon library)? (yes/no)
(default is no) :

-n Do you want to build a debug or release version?
(default is debug) :

-n Do you want to include tests in the debug build? (yes/no)
(default is yes) :

[Benito van der Zander]

The crash handler (that stops a crash and prints a backtrace instead) fails to compile. Perhaps it only works with gcc, not clang. Afair you can disable it with:

./BUILD.sh DEFINES+=NO_CRASH_HANDLER

[Jakob]

Alright: When I comment the if in texstudio.pro in order to enforce DEFINES+=NO_CRASH_HANDLER, the compilation (in debug mode) runs through and the funny thing is: Without changing anything in the source code I can compile my whole dissertation, which did not work on the pre-compiled version. Furthermore, texstudio is still usable during compilation, while it freezes in the pre-compiled version (which is actually annoying). But the scaling of bottoms etc. changed quite a bit, so it looks quite ugly. Furhtermore, Mac's fullscreen mode works fine in the pre-compiled, while it is not available, when I compile it.
The difference I can find: I compiled with QT 4.8.5, while you use 5.2.0. Any ideas, what is going on and how I could a version, that compiles and does not hurt my eyes?

[Tim Hoffmann]

Does it still happen with version 2.8?

[Jakob]

Awesome, problem solved + texstudio responds during compilation! Thanks a lot for your effort!
