Thanks!

@sifmelcara it doesn't look like rstudio uses the updated rsconnect that you've updated

I'm using the master branch of nixpkgs & installed rstudio via: nix-env -f ~/src/nixpkgs -i -E 'f: let pkgs = (f {system = "x86_64-linux";}); in pkgs.rstudioWrapper.override { packages = [ pkgs.rPackages.PKI pkgs.rPackages.RCurl ]; }'

In the ide I see:

> packageVersion("rsconnect")
[1] ‘0.8.5’

thoughts?

Hmm... It even failed to show the gui on current master.

This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".

Reinstalling the application may fix this problem.
Aborted

After bisecting, I found it was broken by #33297 being merged into master.
Maybe this issue is also related to #33702 ?

@joncfoo Although I'm not a expert about R and rstudio, I think you may got that 0.8.5 version because you have installed rsconnect in your home directory? (~/R maybe?)
When I tried your command, rstudio simply tells me that rsconnect is not installed.
Also it seems there is no need to manually fetch packages when compiling rstudio anymore.. because upstream have decided to not to install those packages when installing rstudio ( rstudio/rstudio@3198140#diff-a5cf8527025032071e38a684d4b25d01 )

@joncfoo What I tried to say is that rstudio seems not to come with rsconnect and rmarkdown anymore. We should install those packages by install.packages().
https://cran.rstudio.com/web/packages/rsconnect/index.html
And it seems the new version of rsconnect have not been uploaded to CRAN

@sifmelcara did you install Rstudio in your profile or started it via nix-shell? It could also be, that you have the wrong qt version installed in your profile. Some explanation from @ttuegel #30551 (comment)

@Mic92 I started it by executing nix-build -A rstudio then ./result/bin/rstudio.
So the only correct way to test rstudio is to install it to user profile via nix-env? It indeed works for me.

So I found setting QT_QPA_PLATFORM_PLUGIN_PATH make it work without installing into profile, not sure if this is the correct solution though.

   postInstall = ''
-      wrapProgram $out/bin/rstudio --suffix PATH : ${gnumake}/bin
+      wrapProgram $out/bin/rstudio --suffix PATH : ${gnumake}/bin \
+                                   --set QT_QPA_PLATFORM_PLUGIN_PATH ${qtbase.bin}/lib/qt-*/plugins/platforms
       mkdir $out/share
       cp -r ${desktopItem}/share/applications $out/share
       mkdir $out/share/icons

@sifmelcara yes, you need to use nix-env, home-manager or environment.systemPackages in nixos.
I think there is a reason, we can not just set QT_QPA_PLATFORM_PLUGIN_PATH as it would prevent other plugins from being loaded.

Ok, thank you for the clarification!

@sifmelcara thanks for looking into this - I did have rsconnect installed locally as you mentioned.

btw I used propagatedBuildInputs as mentioned in #33702 and got rstudio working. I added the line propagatedBuildInputs = [ qtbase qtwebkit qtwebchannel ];
