As i ask before, to use dart-sqlite, I must install dart-ext:sqlite first. But every time I try to build it, I found error= Can not found dart_api.h. how to fix it?
I install it on ubuntu 12.04.
Thank you
It sounds like you didn't follow the build instructions:
Either edit build.sh to point to the SDK, or set the environment variable DART_SDK.
Once you correctly point DART_SDK to the dart-sdk directory of your local Dart installation, the build system will find $DART_SDK/include/dart_api.h just fine.

I'm using visual studio code to program in R and I have recently had trouble using the ?func and ??func command.
When typing something like ?rnorm, the message Couldn't show help for path: /library/stats/html/Normal.html shows up. The path is there and I'm sure R is in the path environment. This is really boggling me.
When I first installed R it was working absolutely fine in VSC but now it does not work. However the function works in the R shell. When I try to navigate to the R extension and click on "Help Topics by Package" it says help provider not available.
The packages/html files are there, but VSC doesn't want to access them.
Please advise what I can do to solve this.
I solved the same issue by checking my environmental variables. The steps I followed:
I added the bin installation file (C:\R\R-4.1.3\bin in my case, or C:\Program Files\R\R-4.1.3\bin) to the path in my user environmental variables. If you have an admin account, then you have to add the bin folder to the system environmental variables.
Check if you can start a R console from any terminal.
If that is positive, then in the Rpath settings for the R extension in vscode write r, or in the settings.json: "r.rpath.windows":"r"
Restart vscode. Check if the help pages are working.
Hope this helps ! Cheers.
This happened to me as well. I googled and tried different things and this works for me:
You need to provide the Rpath for the system you are using in the settings for the vscode R package. For example, for a windows machine, you need C:\Program Files\R\R-4.1.3\bin\x64\R.exe there if you installed the latest R using the default settings, and similarly for other systems.
Hope it helps!
I installed Scilab 5.5.2 on Windows 10, and then installed the Scilab Code Generator toolbox.
However, when I start Scilab, the following message appears and I can't use the toolbox. This problem occurs for every toolbox.
Start Scilab Code Generator
Version: 0.9.20190122
Load macros
atomsLoad: An error occurred while loading 'xcos_code_generator-0.9.20190122':
File "C:\Users\光\AppData\Roaming\Scilab\SCILAB~1.2\atoms\x64\XCOS_C~1\09E129~1.201\macros\names" does not exist or read access denied.
(光 is my username.)
I suppose the problem comes from "\Scilab\SCILAB~1.2" in the middle of the file path. In my computer, the only folder in "Scilab" is "scilab-5.5.2", so indeed the software cannot find the file it's looking for.
Does anyone have any ideas?
I need to use the toolbox at work soon, so any help is greatly appreciated. Thank you in advance.
Note: I'm not using the latest Scilab 6.0.2 because it fails to work on my computer. It closes immediately after I open it.
I solved the problem by myself.
It was my user name "光" that caused the problem. I found people saying that user names in full-width characters such as Japanese sometimes cause problems like this.
The solution is to create another user account with a name in half-width characters and install Scilab in that account. (Just changing the full-width user name doesn't work because it doesn't change the filenames that already exist.)
I couldn't find the solution until today because I was searching for solutions only in the context of Scilab, not in the context of software in general.
I hope this answer helps someone.
I'm not sure why you are using an outdated version of Scilab. The latest version is 6.0.2 on Windows. If the newer version doesn't work properly then that's the problem you need to fix first. To test your Scilab installation you may run it in the terminal. Find the installation folder. For me, it is C:\Program Files\scilab-6.0.2\bin the on cmd go to the path and run Scilex.exe. If not uninstall everything and install it in a proper way. My recommendation is to uninstall the old Scilab you already have. Then:
Install Chocolatey package manager
Open PowerShell as Admin and run choco update all -y, once in a while update your packages this way.
run choco install Scilab -y
then open the Scilab software
run the atomsInstall("xcos_code_generator") in the console
runt the atomsLoad("xcos_code_generator") to make sure your package is installed properly. You should see this as a result:
--> atomsInstall("xcos_code_generator")

I am trying to follow this tutorial, in order to install the Nix package manager in my home directory instead of /nix.
I am doing the PRoot installation (see 2. in tutorial). At the end, the
tutorial proposes to be smart in Building native packages section, to be
able to run packages without PRoot:
To run packages natively (without PRoot) they have to be build from source because all paths to the nix store are hard-coded. It is simple, really:
mkdir $HOME/nix
nix-channel --update
env NIX_STORE_DIR=$HOME/nix nix-env -i nix
And now your Nix store gets built up using the new paths. The built binaries can be run directly from there.
I did that, but I don't see how it frees me from PRoot. If I don't do the /nix mounting point with PRoot, nothing works (no nix-env executable,
I can't install new packages).
Should this NIX_STORE_DIR environment variable be put in my .bashrc ?
It seems I always need to run PRoot because ~/.nix-profile points to
a /nix/... directory:
.nix-profile -> /nix/var/nix/profiles/default
There are more steps in the tutorial (5., 6.) - should I follow them ? It seems they apply only in case of using the manual installation (step 4.),
although it is not explicit.
Any help would be appreciated :)
For anyone stumbling on this old question: there is no currently supported way to install Nix without root. The above wiki was moved to https://nixos.wiki/wiki/Nix_Installation_Guide . It may well be out of date. PRoot could work, but even then, rebuilding the whole store at a different path is not a good idea, not the least because the binary caches won't help and you'll need to build everything.
I suggest trying Nix in a virtual machine or cloud server.
Future people from Google, it's still unsupported but does work. Script here that installs a couple dependencies, builds a temporary Nix, and uses that to install a proper version in your directory of choice.
I have installed meld 3.14.2, at last (on NFS share in Redhat 6.3 server), after nearly 40 hours of efforts , installing each and every dependency and at last seems to be successful. But one finale error needs to be solved:
(meld:20703): GLib-GIO-ERROR **: No GSettings schemas are installed on the system
Trace/breakpoint trap (core dumped)
There was answer here: GLib-GIO-ERROR**: No GSettings schemas are installed on the system
I am not aware of these jargons before. So, please explain in detail what to do.
Do I need to set the variable $XDG_DATA_DIR or not? And if, why and what should be the value?
And I can find that the compiled file is already located in MyApp/share/glib-2.0/schemas.
However, I have also tried the following, even though the compiled schema is already there:
glib-complile-schemas <PATH_TO_SCHEMAS> --targetdir=MyApp/share/glib-2.0/schemas
But still I am getting the error. I have tried the variable too by setting it to MyApp and MyApp/share/glib-2.0/schemas. That too doesn't work.
I have also tried reinstalling gsettings-desktop-config. Still error. In my case, it's 3.12 version.
So, what's going on here?? Please explain. I have been sleepless. :(
Thanks you!
And also for your information, I have installed all the dependencies GTK+,ATK,CAIRO,PANGO etc... under the same installation directory with prefix=<base>/meld/deps.
Example:
meld binaries resides as follows: <base>/meld/bin/
cairo binaries are installed as follows: <base>/meld/deps/bin/
atk binaries are installed as follows: <base>/meld/deps/bin/
Similarly, you can think of other dependencies
Well I am unsure why you are installing it to its own prefix... but just setting GSETTINGS_SCHEMA_DIR to the full path to the schema dir should work.
I try install eclim using Graphical Installer by http://eclim.org/install.html tutorial. Installation process complited without errors, but eclim not working. Not found $ $ECLIPSE_HOME/eclimd file on my eclipse root directory, but $HOME/.vim was created succesful.
Where I should look for eclimd?
I just found this thread with no solution trying to figure out the same thing.
I was able to find the launcher under:
"~/.eclipse/org.eclipse.platform_4.7.0_155965261_linux_gtk_x86_64/"
I was just looking for a solution as I was facing the same problem to choose eclipse installation directory otherwise I was unable to proceed eclim installation. However I tried to choose different directories and finally I found the right installation directory
"/Applications/Eclipse.app/Contents/Eclipse"
That worked for me I hope this will help you as well.
