we are currently trying to run asp.net core 2.0 (latest preview) on Linux arm (Raspberry Pi - Ubuntu Mate) and we were able to solve almost all the issues so application works very well.
Not we are trying to run it with SQL Db (Sqlite) and on Windows, everything works fine, we can connect and read the DB but on the linux, we are getting following error:
System.DllNotfoundException: Unable to load DLL 'e_sqlite3': The specified module or one of its dependencies could not be found. (Exception from HRESULT: 0x8007007E).
I think I already tried everything, installed sqlite on linux, but nothing helped.
Any idea what might be wrong?
Thanks a lot
Rado
i changed the library that I used to connect to sqlite to this one
https://www.nuget.org/packages/sqlite-net-pcl/
and then (and not sure why), on linux, i had to take their implementation of SQLite.cs and manually add it to the project.
So for Linux, i had to have that CS included and for windows, i just excluded it so the one which was part of DLL works. Didn't do more investigation, but it works on Windows and Linux as well.
If you need more help just let me know.

Thanks

I think we'll have to wait, the issue isn't closed.
UPDATE:
this issue is closed and launched new version. You only need install the last version 1.1.8 of the package SQLitePCLRaw.bundle_green and SQLite in ARM works fine.
I am having the same issue and I after some investigation I think this happens because e_sqlite3.dll for ARM is not (yet) included the SQLitePCLRaw.bundle_green package.
This package contains the dll for different architectures but linux-arm is not yet mentioned in the dependencies (linux, osx and v110xp (win7) are).
We probably have to wait until the .NET Core ARM team adds it properly...

Realm is working in my react-native app, (running on iPad simulator). I've found the default.realm file but get the error 'Invalid top array' when trying to open it with Realm Studio. Realm Studio can open the downloaded demo file just fine, but I can't get it to work with my default.realm file for some reason.
I'm a little concerned about the different version numbers. In my project I'm using: "realm": "^4.0.0-beta.0"
However, the newest version of Realm Studio I can find is 3.9.0. I would assume Realm Studio should be 4.something too...
Any advice would be appreciated, this is my first project using Realm, so it may be something obvious that is wrong. I'll gladly provide more info if it could be helpful, but not sure where to begin.
Had this issue with 3.10.0 version.
I think that this issue occurs when you update Realm library version (in my case to 5.0) and still work with the same Realm Studio version (3.10).
So updating Realm Studio to newer version must help.
Interesting thing is that Realm Studio app told me that it was the latest version (3.10) and did not want to update. So I had to manually download the newer one.
I had the exact same issue, with same versions as you describe.
In my case, using Realm Studio 3.9.0 beta 0, helped.
:-) i spent day in this issue thinking something wrong with my code while creating DB.
I think issue was with Realm Studio 3.10.
After updating to Realm Studio Version 3.11.0 (3.11.0.719) Fixed my issue.
I need to migrate an enterprise production database from a Windows source machine running Postgres 9.5 to an Ubuntu destination machine running Postgres 11.6 with < 15 mins downtime. I plan to do this with pglogical, which requires the extension being loaded on both source and destination. I am having trouble with the source side because it is Windows.
I have very little Postgres-Windows experience and can neither find any helpful literature on the specific situation nor can I figure out for myself how to presumably install from source.
I've dug and dug and so far the only answer I've been able to find is "ugh... Windows". It seems like the only way to build from source is using Visual Studio, which I don't have or know how to use.

Alex, the 2ndQuadrant article you link to in your own comment solves this. A few of the project or build options noted there have moved a little bit in the newer VisualStudio Community editions, so I can see where you got hung-up.
Just for kicks I compiled 32-bit DLL on my oldest Windows instance. I included the /Release path so you can grab my DLL & see if it works for you. It's (a) 32-bit because I'm assuming worst-case for an old v9.5 install, and (b) targets Postgres 9.6 because that's what I had installed. Unless there were major API changes though, it should connect to v9.5 without any issues:
https://github.com/mbijon/winpglogical/tree/master
If you find you need a version that entirely matches Postgres 9.5, grab my solution files & VS Community 20xx. Load the project & update the Additional Include Directories in Project Config to target your v9.5 paths. That should be all that's needed to link v9.5 Postgres libs.
I am packaging my app into exe with javafx-maven-plugin. x64 version works well. But then I package x86 version on 32-bit Windows 7 (running in VirtualBox if that's important) with 32-bit JDK 1.8.0_161 and 32-bit Maven. The resulting application installs, but fails to run, claiming that MSVCR100.dll is missing even though it is in the runtime\bin folder. I googled around and found out that this is a JDK bug that was supposedly fixed way back in u40. So why does this still happen?
If I copy that dll manually next to the .exe it starts on one machine (again, in VirtualBox), but for some reason silently crashed on another (real one this time, fresh installation). Found an identical problem in javafx-gradle-plugin issues, though it got resolved when building on newest Win10 version, whereas I'm building on newest Win7.
If I just install Microsoft Visual C++ 2010 Redistributable Package then everything works, obviously, but I don't want user having to do that. So how do I copy .dll with Inno Setup script and how do I figure out the reason behind silent crashing?
I don't think this is related to Windows being 32 bit and it just happens to coincide with your two testing computers. I posted a question that is related here: Failed to find library: jvm.dll. What's going on here?
What you are experiencing is likely a bug on java(fx)packager as described here: https://bugs.openjdk.java.net/browse/JDK-8191176. That bug report claims the bug started on 8u155 and was solved by 8u171 but I am experiencing the bug all the way to the latest 8u172 b03 as I describe here: https://github.com/javafxports/openjdk-jfx/issues/59
I also tried going to 8u144 before the bug existed and I found that building the installer fails because of a missing MSVC dll (surprise! surprise!). I described the problem here: Where/how to get the MSVC dlls Java 1.8.0_144 wants?
There may be another .dll on which MSVCR100.dll depends and which is not present on specific machine.
That is a reason why the Redistributable Package installs everything together.
Try to find another dependencies using http://dependencywalker.com/, it looks like you need more dlls than MSVCR100.dll.
Or simply install Redistributable Package on each machine. Installing it multiple times does not harm any application or system.
I want to deploy my QT program and I can't find the reason it doesn't work, maybe you guys can help me ?
I work with visual studio 2010, windows 7, QT 5.0.2.
I have tested my deployment tree on my own computer and it works fine.
When deploying my application I ship every necessary dll that I am aware of. Depends.exe does not complain. I also deployed the plugin I know of, and since it still did not work I moved my entire plugin folder in the exe folder.
When I execute it on any other computer than my development computer, the program exits instantaneously with no message whatsoever.
Any idea where I should look now ?
How can I debug that kind of issue ?
Did you try deploying the debug version of the program and then starting it from the command line. The debug version will output more information to the console which could help you resolve the issue.
You will have to also deploy the debug versions of the MS c-runtime libraries.
Deploying the debug version is not a permanent solution, so you should not adopt that as normal routine for distributing your software. I am just suggesting that you try running the debug version one time on that particular machine until you figure out the issue. Then remove the installed program and install the release version again.
You can run your application using QtCreator:
Debug > Start Debugging > Start and Debug External Application...
This can give you more information about what's going on.
Hoping that I do this corectly.
I am having the above issue. My development machine is win7 64. Im developing x86 application,(x86 set in compile options). I have downloaded sqlite-netFx40-setup-bundle-x86-2010-1.0.81.0 as my app will be on .net4. I have referenced the above dll, set it to copy local. Can confirm that its in the deployed dirrectory. Tests OK on development machine both as a debug and a fully instaled app. When I put the app on a separate win 7 64bit it wount run due to the Dll. It installs ok into ProgramFiles(x86) and runs untill the database is required. The dll is in the instaled dirrectory when instaled on the other PC. (fresh win instal).
I am using InstalShield and it is also telling me about an error ' -6248: Could not find dependent file system.data.sqlite.dll, or one of its dependencies of component' but it compiles OK.
Im stearing at the Dll in the program , in the references, the intelisence picksup the SQLite name and all the code is right. I have referenced by browse and then finding the dll.
What on earth could I be doing wrong ?
This has had so many views that I decided to answer this so as to help others.
The problem isnt a big deal once you know what it is, despite the error message that sends you almost in the wrong dirrection. The problem isnt the DLL, its one of its dependancies. Basicaly you have to install C++ distributable file on the client machine , even if you are using VB.net.
