Shared Library on Mac OSX and QT - macos

Does anyone know how to get rid of this problem? I am using a Mac for developing for Maemo 5.
Killing remote process(es)...
Starting remote process...
Remote process started.
/opt/Blue/bin/Blue: error while loading shared libraries: libQtConnectivity.so.1: cannot open shared object file: No such file or directory
Finished running remote process. Exit code was 127.
I have followed the instructions here:
http://www.developer.nokia.com/Community/Wiki/Latest_Qt_and_Qt_mobility_evaluation_on_Maemo
I think I just need to make sure my mac links to that file, how to do that?
Building the package is fine but I get the error when I try to deploy it on my N900 phone. The error appears in the QTCreator output.

Running OpenFOAM native compile on a non-admin Windows

I have downloaded and installed a Windows native compiled OpenFOAM from here. But when I try to run any of the OF commands (e.g., blockMesh, foamDictionary, ...) in the MSYS2 terminal I get the message:
path/to/folder/v2106/msys64/home/ofuser/OpenFOAM/OpenFOAM-v2106/platforms/win64MingwDPInt32Opt/bin/blockMesh.exe: error while loading shared libraries: libstdc++-6.dll: cannot open shared object file: No such file or directory
and in the cmd terminal, I get the error message:
System Error The code execution cannot proceed because msmpi.dll was not found. Reinstalling the program may fix this problem.
From here, I see that I might have to reinstall OpenFOAM in admin mode, which I don't have on this work machine. so I tried installing MSMPI using pacman -S msmpi as I used to do here. But I get the error message:
error: target not found: msmpi
My goal is to install and use the OpenFOAM software, doesn't matter which release, on this Windows machine without admin privileges. I would appreciate it if you could help me know how can I fix the above problems, or find another way around.
P.S.1. Searching the installation directory, I see that the libstdc++-6.dll file is in the path\to\folder\v2106\msys64\home\ofuser\OpenFOAM\OpenFOAM-v2106\platforms\win64MingwDPInt32Opt\bin. So I wonder I get the first error message. Maybe OF is not compiled properly against the library? Should I try removing the path\to\folder\v2106\msys64\usr\lib\gcc\x86_64-pc-msys\7.4.0\libstdc++.dll.a as suggested here?
P.S.2. I had written this post ages ago about different ways to install OpenFOAM on Windows. Sadly it is still a big effort to get it up and running.
P.S.3. A follow-up on this issue here on the MSYS2 Discord server.
P.S.4. Opened a new issue here on the OpenFOAM repository.
With OpenFOAM-v2112 it is now possible to install without windows admin permissions.
The original problem will still be evident with older OpenFOAM versions since they relied on installing msmpi separately.

"GPU process isn't usable. Goodbye."

I'm experimenting with building a Windows and Mac OS app using Electron and have hit a snag.
In short, if I try to run the application directly with Electron on Mac OS Big Sur (as opposed to building a Mac app and then running that) I get the following error returned:
[35941:0821/171720.038162:FATAL:gpu_data_manager_impl_private.cc(415)] GPU process isn't usable. Goodbye.
I am running directly with Electron using the following in my package.json:
"scripts": {
...
"test": "electron main.js",
...
}
So far the only Mac OS environment I have access to is Big Sur so haven't tried this on earlier versions of Mac OS but from Googling it seems this error may be related to Big Sur's tightened security/sandbox constraints -- but I am guessing about that.
In any case, after some Googling several suggestions indicated trying to run without the app sandbox, i.e. adding this to main.js:
app.commandLine.appendSwitch('no-sandbox');
That's all well and good and works.
However, if I ever want to build and distribute a signed Mac app targeting the Mac App store or a just a signed, sandboxed DMG or PKG installer, then this won't be suitable.
If I remove the above no-sandbox command from main.js and specify the app sandbox in my entitlements plist as shown below the resulting signed app will not run:
<key>com.apple.security.app-sandbox</key>
<true/>
The app tries to open and just closes. I can try running at the command line with open <appname>.app but this throws the following error in the console:
The application cannot be opened for an unexpected reason, error=Error Domain=NSOSStatusErrorDomain Code=-10826 "kLSNoLaunchPermissionErr: User doesn't have permission to launch the app (managed networks)" UserInfo={_LSFunction=_LSLaunchWithRunningboard, _LSLine=2561, NSUnderlyingError=0x7fd3c9c13db0 {Error Domain=RBSRequestErrorDomain Code=5 "Launch failed." UserInfo={NSLocalizedFailureReason=Launch failed., NSUnderlyingError=0x7fd3c9c158e0 {Error Domain=NSPOSIXErrorDomain Code=153 "Unknown error: 153" UserInfo={NSLocalizedDescription=Launchd job spawn failed with error: 153}}}}}
If I build a signed app with no-sandbox enabled, the app will run just fine on Big Sur using open <appname>.app.
I have tried my best through Google, Stack Overflow, etc to diagnose this but am not getting anywhere. Here's to hoping the Stack Overflow community can provide me the critical clue to solving this.
For further context, I created a new, empty Electron application and followed the Electron Quick Start Guide to the section where it describes creating an empty main.js which technically should allow the Electron app to start -- but it won't. The same error describe above re the GPU gets thrown even without instantiating a BrowserWindow or writing any custom code of my own.
NEW UPDATE: I set these environment variables to true and then tried running the app with npm start:
ELECTRON_ENABLE_LOGGING
ELECTRON_DEBUG_NOTIFICATIONS
ELECTRON_ENABLE_STACK_DUMPING
The result is more detailed error output:
[48836:0823/165857.676747:ERROR:icu_util.cc(179)] icudtl.dat not found in bundle

Haven't had time to do the research as to what ICU refers to but thought I would update with this info.
ANOTHER UPDATE: all this has been done on Mac OS Big Sur which is my main development machine. Trying this on a Windows 10 machine, using the same Electron code, dependencies, etc and things work fine. So the problem is either related to Mac OS Big Sur or a specific local issue on my development machine which I cannot identify. Any suggestions on how to diagnose this will be much appreciated.
ONE MORE UPDATE: Based on a guess, I created a new user on my mac, took the code in there and it ran perfectly. So -- this probably means that I need to find something installed in my profile or some corruption in my own profile/settings that is breaking things. As always, any suggestions appreciated it.
In my case, I got this to work using command line switch, --in-process-gpu, or:
app.commandLine.appendSwitch('in-process-gpu');
There's also an extensive list of Chromium switches here that you can try at:
https://peter.sh/experiments/chromium-command-line-switches/
Yeah, the whole hardened runtime thing is just such an awful, awful mess! Now to figure out the next crash!
So -- partial answer. I think I've found the solution to this error:
GPU process isn't usable. Goodbye.
My development directories are all on a file system accessed via a symbolic link. As soon as I moved the folder for this app to my my home directory (no symlinks involved) I could launch with npm start without needing to enable no-sandbox and without seeing this error or the errors related to icudtl.dat.
I haven't yet determined if the problem described with the error below when launching the packaged app is related/solved:
The application cannot be opened for an unexpected reason, error=Error Domain=NSOSStatusErrorDomain Code=-10826 "kLSNoLaunchPermissionErr: User doesn't have permission to launch the app (managed networks)" UserInfo={_LSFunction=_LSLaunchWithRunningboard, _LSLine=2561, NSUnderlyingError=0x7fd3c9c13db0 {Error Domain=RBSRequestErrorDomain Code=5 "Launch failed."

That said, it is a big step forward.
I have a similar issue on a linux machine with an electron app. The answer in this github issue helped me.
Using --disable-gpu-sandbox flag with electron apps solved it for me.
The underlying problem seems to be that the Mac OS sandbox is preventing the GPU process to spawn properly.
You can specify a variety of entitlements when packaging your application, but not all entitlements are created equally, especially entitlements that want access to the keychain, secure enclave and TouchID.
If you're specifying a provisioning profile - make sure that all those entitlements are only in the original file, keep your inherited entitlements empty or to the bare minimum. In my case, I had the keychain-access-groups specified in my inherited entitlements which was a painful lesson to learn. Removing it made the builds not crash!
I believe in your case it's likely that you tried to access files outside of the application itself which might have caused the sandbox to prevent opening the GPU processes.
I know the OP reported this against MacOS, but on my Windows 10 VM I used the following instructions to create the electron-quick-start app…
net use T: \\busdata\company\BrianT
T:
cd \Development\Sandbox\electron
"C:\Users\thomasb\AppData\Local\GitHubDesktop\app-2.9.15\resources\app\git\cmd\git.exe" clone https://github.com/electron/electron-quick-start
cd electron-quick-start
npm install && npm start
…and then electron wrote error messages to the console, the same errors as those reported by the OP:
[5796:1025/121431.238:ERROR:gpu_process_host.cc(969)] GPU process launch failed: error_code=18
[5796:1025/121431.328:FATAL:gpu_data_manager_impl_private.cc(441)] GPU process isn't usable. Goodbye.
An earlier answer mentioned symbolic links, and to investigate that further I xcopied the entire electron-quick-start folder down from T: (a remapped network folder) to C: (my local disk).
When I then ran npm start in the folder that I'd copied down to C: there was no error.
Looks like electron is being fussy about where the source files live.
I had the same Issue when running the files off of a server such as a nas, but moving files to local storage solved the issue.

Signing error when trying to open executable created with raco (macOS)

I've been breaking my head on this issue and have come to SO to ask for some help. I'm running Racket v7.7 on macOS 10.14. I've built an application with a GUI (https://github.com/layetri/markoviser), and when I compile it with raco exe --gui, all is fine. That is, until I try to execute the created .app. The program seems to start for a few seconds, but then dies. Looking at the Console, tccd gives me the following error:
Failed to copy signing info for 10203, responsible for file:///Users/layetri/Development/markoviser/Markoviser.app/Contents/MacOS/Markoviser: #-67062: Error Domain=NSOSStatusErrorDomain Code=-67062 "(null)"
...after which the program quits. Would anyone know what I'm doing wrong or what I can do about this?

Unable to start LLDB in Qt Creator Mac OS X

I'm transitioning to Mac OS (from Win and Linux) and today I got strange messages while trying to debug some code:
Unable to start LLDB "/Applications/Xcode.app/Contents/Developer/usr/bin/lldb": chdir: No such file or directory.
The LLDB process failed to start. Either the invoked program "/Applications/Xcode.app/Contents/Developer/usr/bin/lldb" is missing, or you may have insufficient permissions to invoke the program.
What's going on?
I had the same problem when I set my working directory to a folder that didn't exist. Changing my working directory to an existing path fixed the issue.

External makefile in Atmel Studio won't build. Windows error 0xc0000142

I downloaded bitcloud, the atmel zigbee stack and I am trying to compile one of the default applications, ZLLDemo.
It is located currently at:
C:\Users\Ryan\Desktop\BitCloud_MEGARF_3_1_0\Applications\ZLLDemo\atmelStudio_projects\ATmega256RFR2.cproj
Everytime I try to compile the application I get a windows message screen for "mkdir.exe" error 0xc0000142. In the Output screen I see the line "make: *** [directories] Error -1073741502"
This same error and error code occurs later in the build process for cp.exe if I manually make the folders myself.
I have tried the following things to fix the error:
Change folder and contents to different owners, everyone having full
privileges
run make command manually from a command prompt window as admin
clean solution before retrying
all other examples files
ran directly from C: as "C:\BitCloud_MEGARF_3_1_0\Applications\ZLLDemo\atmelStudio_projects\ATmega256RFR2.cproj" - as per general suggestion for the windows error I tried
"sfc /scannow" in case mkdir had somehow been corrupted
Changed AppInitDLLs Reg key to 0 to load all DLLs at start of application
Disabled Internet security
Does this have a general fix or is there perhaps something else at work here? General compilations work, its just external ones. My friend did the same and it seems to work just fine for him.
Windows 8.1
Atmel Studio 6.2
Avrfreaks had a solution that I finally found here.
Their solution is to download an old version of the msys file for winavr. Which means that their is something more than likely wrong with the latest version of winavr for windows 8.1
