i added the gdb output, i hope that helps to find the bug!? |
|
@niemeyer do you have time to look at it or do you need more infos? |
|
The debug run doesn't really show much. The most interesting information there is this line: Would be worth finding out which function and parameter is being complained about. Unfortunately, I don't have a Windows environment where I might debug this, so we'll need someone able to look at it. |
|
i could investigate more, how can i figure the function gdb is complaining? single step until the message appears? |
|
Single step would be painful. Try stepping over the main lines, and then once you figure out where it's coming from, step into the specific function failing. Would also be worth finding out what's going on when asmcgocall is failing. The actual crash point reported is apparently within exit finalizers, which might imply the real issue is being hidden by these errors. |

@niemeyer is this debug output useful to find the issue? |
|
Not much.. still have no idea about which function it's complaining about. |
|
Actually, it does give a hint.. it might be something around the memory fencing that is done in the idle timer. |
|
whats wrong here? gopkg.in/qml.v1/_obj/_cgo_defun.c: No such file or directory. |
|
That file is generated by cgo. You can have a look at it by preserving the work directory during build with |
|
idleTimerInit doesnt have anything windows specific!? |
|
The code there was already tweaked quite a bit so it actually worked on Windows, and it did work. I don't know what's wrong for your case, and we'll likely need someone that has more familiarity with the environment to tell. |
|
Gerald, have you tested with go 1.2? It worked for me (but even 1.3 did

@neclepsio: same error with go 1.2.2 |
|
Same issue, segfault at Compiling the Qt Gui examples ( |
|
Tried to run the test program in this issue and the example in "examples/controls/basiclayouts". Here are the results: Machine 1: Windows 7 32-bit, Go 1.3.1, Qt 5.3.2:Starts and workds well! Machine 2: VM, Windows 10 Technical preview x64, Go 1.3.3, Qt 5.3.2:Starts (not crashing like OP) but shows empty white window. A lot of messages in the console. |
|
I'm getting a crash on 64bit windows which seems similar. details: My stripped down crashy program: I can compile and run a simple cgo 'hello world' ok. Next step I think is to try compiling my own QT from source, on mingw-w64 (not looking forward to that...). I'll probably try msys2 & pacman first, just of the off chance. I don't really expect any solutions, just wanted to add some more data! |
|
I faced the problem same as you, too. |
|
can you try go 1.4 rc2? |
|

Hi, Sorry, my trouble is same as Mr. bcampbell's trouble. regards. |
|
does it also work with mingw 4.9.1 - 32 bit? |
Yes, crash is reproduced on Qt5.3.2 built by MinGW 4.9.1 rev.2 32bit, and is gone by ANGLE patch.
No, I used for 32bit MinGW that is "i686-4.9.1-release-posix-dwarf-rt_v3-rev2.7z" downloaded from http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/mingw-builds/4.9.1/threads-posix/dwarf/ . And there is a additional information. |
|
just wondering why MinGW 4.9.1 is not in Minimalist GNU for Windows?!? |
|
I do not know it. |
|
I have the same problem. test on QT5.4 MINGW 4.9.1 and QT 5.3.2 mingw 4.8.2 , windows 2003, |
|
The patch https://github.com/noliar/qml/commit/352842b73ada0fc32d94cf91e75541e590675f82 solves "signal arrived during cgo execution" (Go 1.4, Qt 5.4, MinGW 4.9.1, Windows 7 32-bit) |

hi,
if i execute the following program i run into a seg fault:
here my test program:
i use go-qml on windows 7 32 bit with the following configuration:
edit: same error with go 1.3.3

i copied all dlls from C:\Qt\Qt5.3.2\5.3\mingw482_32\bin to the direcory of the executable, just to make sure i dont miss any dll...
the app crashes:
debug session with liteide, which comes with gdb:
to investigate this further, i started gdb without liteide:
from what i see, the issue is caused by the timer!?
