using Sqlite;
an error occurs: "The namespace name` Sqlite 'could not be found "
I previously installed SQLite and command line compilation works :
valac --pkg gtk + -3.0 --pkg sqlite3 -X -lm SomeFile.vala
But if I create and compile a project in Anjuta, then an error occurs
I use VS Code with VLS and Builder, but I think the same is true for Anjuta(is this IDE still alive?) For correct operation Vala Language Server all dependencies should be described in the Build file Meson. For the Vala Language Server to work correctly, all the dependencies must be described in the Meson Build file.
Here is an example that I use with the plugin for VS Code:
project('vala app', 'vala', 'c')
dependencies = [
dependency('glib-2.0'),
dependency('gobject-2.0'),
dependency('sqlite3'),
dependency('gee-0.8'),
]
sources = files('valite.vala')
executable('valite', sources, dependencies: dependencies, install: true)

I am trying the new R package rhino from the Appsilon team to build shiny apps.
Running on a Windows10 laptop I installed the dependencies node.js and yarn as described in this tutorial.
Here is the output of rhino::diagnostics() :
Windows 10 x64 build 19042
R version 4.1.0 (2021-05-18)
rhino: 1.0.0
node: v16.15.0
yarn: 1.22.15
Running rhino::build_sass() gives me this error:
yarn run v1.22.15
$ sass --no-source-map --style=compressed root/app/styles/main.scss:root/app/static/css/app.min.css
Error reading root\app\styles\main.scss: no such file or directory.
error Command failed with exit code 66.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
Error:
! System command 'yarn' exited with status 66.
i If you can't use Node.js and yarn, try using sass: 'r' configuration.
Run `rlang::last_error()` to see where the error occurred.
I am puzzled by the paths in the call to "sass" that start with "root/app". My app is located in my home directory:
"C:/Users/XXX/Documents/workspace/rhino_dummy"
Is it possible that these paths are wrong in the call?
Luckily, the suggested alternative with the deprecated libsass interpreter works for the sass example in the tutorial. It would be nice to have node.js with sass working on Windows10 for future more complex apps.
Edit 1, after Kat's comment
Thanks Kat for the quick feedback. I added sass via yarn add sass and tried again same error:
> rhino::build_sass()

$ sass --no-source-map --style=compressed root/app/styles/main.scss:root/app/static/css/app.min.css

The warning is coming from the pckage.json file that was created by calling yarn inside my R project folder. It has only minimal content:
# package.json
{
"dependencies": {
"sass": "^1.51.0"
}
}
Out of curiosity, I tried to compile the javascript example, also failed with very similar error regarding folder paths:

For Node.js functions to work on Windows 10, you'll need to enable Developer Mode on your system as mentioned in our How-to: Use Rhino on Windows article. This is necessary for symbolic links to work on Windows (and the .rhino/node/root file is a symbolic link to the root of the project).
After you do that, delete the .rhino/node directory from your project, or run rhino:::add_node(clean = TRUE) in the root of your project.
Workaround
This answer is only a workaround, if you cannot enable developer mode on windows (see Kamil Zyla's post for more information).
It looks like the folder name "root" in the error messages is a broken variable.
The folder ...\workspace\rhino_dummy\.rhino\node\root does not exist, but the substructures do exit:
app\styles\main.scss
app\js\index.js
...\workspace\rhino_dummy\.rhino\node
Fix step1
I tried my luck and created the folder "root": C:\Users\XXX\Documents\workspace\rhino_dummy\.rhino\node\root
copied rhino_dummy\app\styles\main.scss to rhino_dummy\.rhino\node\root\app\styles\main.scss
copied rhino_dummy\app\js\index.js to rhino_dummy\.rhino\node\root\app\js\index.js
running rhino::build_sass() and rhino::build_js() now worked!

I pulled down the qtpdf repository to check out and play with from here:
http://code.qt.io/cgit/qt-labs/qtpdf.git
As soon as I open the qtpdf.pro file, I get the following general messages:

Project ERROR: Unknown module(s) in QT: pdfwidgets
Project ERROR: Unknown module(s) in QT: pdf
Also when running "rebuild all" I get the following error message:
16:15:33: Starting: "C:\Qt\Tools\mingw530_32\bin\mingw32-make.exe" qmake_all
"Some of the required modules (!qnx:!uikit:!winphone:!winrt:!win32-g++:!integrity) are not available."
"Skipped."
I've narrowed this down to !win32-g++ - If I remove that, it won't throw that error, but I don't understand what exactly this error means - I have googled around a lot but couldn't find anything that seemed reminiscent of this particular problem.
I managed to build qtpdf with mingw provided with Qt5.11.2.
Comment out "requires(!qnx:!uikit:!winphone:!winrt:!win32-g++:!integrity)" from pdf.pro
Apply the patch found here : https://github.com/Alexpux/MINGW-packages/blob/master/mingw-w64-pdfium-git/pdfium-2729.patch (link dead in 2021, no backup sorry)
Add -luuid after "win32: LIBS_PRIVATE += -ladvapi32 -lgdi32 -luser32" in lib.pro
I don't know why, probably because I am not an expert, but mingw doesn't generate correctly the folder "include". As a workaround I use the one generated under linux. For some reason, mingw generate only QPdfDepends and QPdfWidgetsDepends, none of the needed headers are generated. I didn't dig because I am lazy.
Hope it helps !
# Upstream PDFium has not been ported to various platforms yet.
requires(!qnx:!uikit:!winphone:!winrt:!win32-g++:!integrity)
The module is not working on win32-g++ (mingw32).
I want to connect to Mongo DB using Robot Framework.
I have read in the following link that we have to pull the source code and install the library. Robot FrameWork - MongoDB-Library
I installed the Library and it is installed in the location

When I add 'MongoDBLibrary' library in the RIDE it showing in red (means library is not installed properly),
when i ran the same using eclipse + Maven project i got the following error

Make sure you have installed PyMongo (or bson):
pip install pymongo
pip install bson (don't know if still required then)
I’ve just installed v-play but when i compile to desktop i get error :-1: error: cannot find -lGL and exits.
Then if i compile to android it will compile and install but the it never successfully opens the app and it exits on deployment.

I'm trying to get smaller scalar executable jar file with sbt-proguard.
I added project/plugin.sbt these two lines of code:
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.13.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-proguard" % "0.2.2")
The first one is to get uberjar file, and I could get uberjar with sbt assembly that works fine.
Then, I executed sbt proguard:proguard to get this error message.
[error] Error: Can't read [/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/jre/lib/rt.jar] (Can't process class [apple/applescript/AppleScriptEngine.class] (Unsupported class version number [52.0] (maximum 51.0, Java 1.7)))
java.lang.RuntimeException: Proguard failed with exit code [1]
at scala.sys.package$.error(package.scala:27)
...
at java.lang.Thread.run(Thread.java:745)
[error] (proguard:proguard) Proguard failed with exit code [1]
From the hint from this post: ProGuard says Unsupported class version number [52.0] (maximum 51.0, Java 1.7) with sbt-proguard,
I switched to both Java 1.7 and Java 1.6 with export JAVA_HOME=/usr/libexec/java_home -v '1.6*' command to run proguard to get the slim-lined jar file, but this doesn't run.
Invalid or corrupt jarfile target/scala-2.11/proguard/myproject_2.11-1.0.jar
What might be wrong? These are the lines that are added to build.sbt.
proguardSettings
ProguardKeys.options in Proguard ++= Seq("-dontnote", "-dontwarn", "-ignorewarnings")
ProguardKeys.options in Proguard += ProguardOptions.keepMain("core.HelloWorld")
I believe this is documented in the pro guard docs.
Running your application with java -classpath <jarpath> --class classname <program-arguments> should work.
This happens because pro guard by default removes all MANIFEST files from the jar hence the java runtime cannot find the jar class entries. Another way to do this would be to keep the MANIFEST.md file and run it using the java -jar option but I have never tried that.
Define a recent Proguard version that supports Java 1.8
ProguardKeys.proguardVersion in Proguard := "5.3.3"
Also a couple of useful ones if you run out of mem are
javaOptions in (Proguard, ProguardKeys.proguard) := Seq("-Xmx2G")
javaOptions in (Proguard, ProguardKeys.proguard) += "-Xss1G"
