Hi,
Just wanted to let you know that we have updated VisualGDB to run the Cygwin build of CMake using an alternate mechanism that does not trigger the problem. Please use this build: http://sysprogs.com/files/tmp/VisualGDB-5.4.7.2524.msi
It also looks like as of v3.12, the Cygwin-based build of CMake would crash when trying to reload a project without restarting it:
assertion "0" failed: file "<...>/CMake/Utilities/cmlibuv/src/unix/core.c", line 185, function: uv_close 0 [main] cmake 33156 cygwin_exception::open_stackdumpfile: Dumping stack trace to cmake.exe.stackdumpIf you ever encounter that message, please right-click on the project in Solution Explorer and select “Reload CMake Project”. This will restart CMake and reload the project successfully.
Hello,
It seems that i missed the link you posted, it is already unavailable.
Please let me download it again.
Hi,
Sorry about that. Please download v5.4 Preview 8. It includes all the fixes from all previous builds.
Hello,
I’ve installed the v5.4 Preview 8.
I succeeded to load the project without errors.
The problem you mentioned happens every time i try to build the project.
On the build command i get following message:
Code model queried in 1483 msec
assertion “0” failed: file “/home/salex/CMake/Utilities/cmlibuv/src/unix/core.c”, line 185, function: uv_close

VisualGDB: Error: Command-line action failedHi,
No problem, we can add a workaround to the first problem that will automatically restart CMake if it crashes during reconfiguration.
The second problem looks like you are using backward slashes in the path to GNU Make (configured via VisualGDB Project Properties). Please try using forward slashes instead and let us know if this solves the problem.
Hi,
No problem. Please try this build: http://sysprogs.com/files/tmp/VisualGDB-5.4.9.2552.msi
Hi,
This version one is working. It started to build the program.
The next problem is that the VisualGDB executes bash.exe of Cygwin without login option.
VisualGDB: Run “C:\PX4\toolchain\cygwin64\bin\bash.exe -c “make “” in directory “c:\PX4\home\Firmware\VisualGDB\Debug” on local computer
This causes that some python scripts, which are activated from the CMakeList, cannot import modules (numpy).
I tried manually to do this, and bash.exe -l , should solve the problem.
Can i add this option in configuration, or the command is hard-coded in VisualGDB ?
Hi,
Yes, you should be able to customize the build command line via VisualGDB Project Properties -> CMake project settings -> Make Command.
It doesn’t work this way.
If i put it before make command, meaning it will appear immediately after bash.exe, it recognizes the -l as invalid option.
It looks like it should be hardcoded in bash command, my be as an option.
Hi,
Strange. Could you please share a screenshot of your settings and the command line shown in the build log?
Hi,
The screenshot of the settings is in the attachment.
And here is the screenshot of error message:

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========Hi,
Sorry for the delay. We have pinpointed and fixed the issue in this build: http://sysprogs.com/files/tmp/VisualGDB-5.4.9.2571.msi
Hi,
Thank you for your efforts.
Now i can see the login command, but something strange happens. The make is not starting at all.
I tested again with version VisualGDB-5.4.9.2552, the command line looks same, but without –login, and make process is working (until it stops on because of login problem).
Here is the output of the latest VisualGDB:
—— Build started: Project: Px4_WinGDB, Configuration: Debug VisualGDB ——
VisualGDB: Run “C:\PX4\toolchain\cygwin64\bin\bash.exe –login -c “make “” in directory “c:\PX4\home\Firmware\VisualGDB\Debug” on local computer

Hi,
Sorry about that, looks like our bug (we did not compensate for the fact that –login resets the working directory). We have updated the logic for wrapping the Cygwin commands in this build and tested it in several scenarios, so it should finally work: http://sysprogs.com/files/tmp/VisualGDB-5.4.10.2583.msi
Please open the toolchain editing window and manually set the command launch mode to “Interactive Bash Session”.
