How to get latest chromium code, and compile it in debug mode? I am using ubuntu 10.04.
If you only need a Chromium package with debug mode enabled, you can easily install chromium-browser-dbg from the Chromium PPA.
Checking out from SVN can take a long time.
You can download the source tarball in
http://dev.chromium.org/developers/how-tos/get-the-code
The link also contains instructions of how to build code under Ubuntu.

I was trying to run a flutter app on Ubuntu 22.04 LTS. Everything was working fine. But, today this problem came up while running the app. The Flutter SDK fails to build the app throwing the below error.
/snap/flutter/130/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/../../../../lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by /usr/lib/x86_64-linux-gnu/gio/modules/libgvfsdbus.so)
Failed to load module: /usr/lib/x86_64-linux-gnu/gio/modules/libgvfsdbus.so
After searching on the internet I realized I need a backward version of libc. If I do file /snap/flutter/130/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/../../../../lib/x86_64-linux-gnu/libc.so.6.
I get the result /snap/flutter/130/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/../../../../lib/x86_64-linux-gnu/libc.so.6: symbolic link to libc-2.31.so.
Probably I need to install libc-2.31. But, how? I did not find any solution. Both Flutter and Ubuntu are upgraded to the latest versions.
It's a snap problem with vscode.
First remove vscode :
sudo snap remove code
Then download the .deb of vscode here : https://code.visualstudio.com/docs/setup/linux
And install it with :
sudo apt install ./<file>.deb
moving to edge channel, snap refresh flutter --edge
running flutter upgrade
deleting build directory rm -r build/
running the application again flutter run -d linux
reference this
I had this problem. I just uninstalled and reinstalled flutter. It worked nice.
snap remove flutter
snap install flutter
flutter doctor
After searching on the internet I realized I need a backward version of libc.
No, you don't.
The error means: the version of GLIBC you are using is too old and does not satisfy requirements of the system libgvfsdbus.so which you are trying to load.
Your application appears to be using a custom version of GLIBC, located in /snap/flutter/130/lib/x86_64-linux-gnu/libc.so.6, which is older than the system-installed GLIBC (which is likely 2.33 or newer).
I don't know whether Flutter makes you use a custom GLIBC, or whether you chose to do so on your own. Either way, this seems like a terrible idea.
If you must use custom GLIBC for this app, then you should not use any system libraries (such as /usr/lib/x86_64-linux-gnu/gio/modules/libgvfsdbus.so) in it.
I want to add Doxygen plugin to QtCreator.
I am using QtCreator 2.5.2 in ubuntu 12.10 and the latest Doxygen version for QT is 2.4.0.
I've changed the doxygen.pluginspec file to get rid of version error.
But now I've got another error:
can not load library libdoxygen.so (libQtconcurrent.so can not open shared object file:No such file or directory)
Any suggestion would be appreciated.
I hope you are no longer stuck, but if not, I will still try to help.
Yes, the quick install binaries are available only for QtCreator 2.4, but the plugin stays easy to install without it : you have to download the sources and build them yourself, as written in the wiki.
Moreover, you have to build it with the same version of Qt4 as the one that was used for build your QtCreator (have a look here)
It became compatible with QtCreator 2.7 and Qt5 at the end of March, and I succeeded in installing in in QtCreator2.8-beta.
If you have any other question, I guess it would be better to ask them in the plugin forum where developpers always answer to people in need.
Hope this helps (you and other people in need).
You can install Doxywizard wich provides an user interface to use Doxygen.
I'm not shure I'm using fedora to install I used.
yum install doxygen-doxywizard.x86_64.
For Ubuntu it should be if the package name is the same.
apt-get install doxygen-doxywizard.x86_64

How to enable debugger in fp-ide? I read somewhere that I should compile fp-ide from sources, but I don't know how to do this. Can someone help me?
Get the generic linux tar installer (fpc-2.6.0.x86_64-linux.tar) for FPC from http://www.freepascal.org/down/x86_64/linux-hungary.var It comes with a precompiled IDE with integrated debugger support and it works fine at least on 12.04 LTS.
I wasn't able to find a PPA for fp-ide, but I can describe how the CLI IDE is compiled on Arch Linux as documented in the repository. Do note that compiling will not enable the debugger in the CLI, as it seems to be an incompatibility between gdb and fp (fp-ide) according to e.g. this bug report in Debian. On Arch Linux, the fpc package also doesn't support the debugger in fp by design (it is explicitly disabled using the NOGDB flag).
Anyhow, here goes the compilation process:
Make sure you have FreePascal installed already, as you need it to compile the IDE
Download the source tarball
Extract the tarball to a location of your convenience and cd into that directory
Execute the following code from within your shell:
pushd fpcsrc/compiler
fpcmake -Tall
popd
make build
make -j1 install
# in Arch, the switch "NOGDB=1" is present in both make lines
That should compile the IDE and install it (you can even try to integrate it in dpkg by using checkinstall instead of make install, but take a look at the Arch PKGBUILD to see an example of what might be needed).
But why do you use the command line IDE fp instead of lazarus? With lazarus you can also make console applications and it offers much more features (e.g. working debug support).
I have installed Node.js on an Ubuntu 64bit server using a standard apt-get and would like to profile scripts through the "--prof" flag.
Web searching shows there should be a tool to process the v8.log output located in "deps/v8/tools/linux-tick-processor" but I don't seem to have any of those directories. Do they come with the native install? should they be installed separately? if so how?
Thank you
You need to download the source package with sudo apt-get source nodejs.The path you mentioned is in there.
You'll need to scons prof=on d8 in deps/v8 to build the debugger first, which might have some trouble on a 64-bit machine (v8 is 32-bit only), see here for more info.
Here's how I did it for Node.js 0.10.25 and 0.10.26:
I downloaded the source for Node.js that corresponds to the binaries I'm using. (I'm on Debian testing, which is a bit behind the releases from the Node.js web site.)
I checked the version of v8 bundled in the node sources. (Look at deps/v8/ChangeLog. It was 3.14.5 for Node.js 0.10.25 and 0.10.26.)
I downloaded this exact version of v8 from the v8 site.
Why? I tried running make native in Node.js deps/v8 directory but the Makefile was complaining about a missing test directory. From this we can infer that the Node developers are not including the entire v8 distribution. Once upon a time, with an earlier version of Node (0.8.something) I did build v8 from what was available in deps/v8 but this time I decided to use a different approach.
As explained in v8's build/README.txt, in the top level of the source tree for v8, I did:
$ svn co http://gyp.googlecode.com/svn/trunk build/gyp
(Linking my installed gyp to build/gyp as suggested in OrangeDog's answer did not work. That's why I did the above.)
I ran:
$ CXX=g++-4.7 make native
Why the CXX setting? I ran into a compilation problem right away when I tried with the default gcc. I checked the version. It was 4.8 and I remembered a story on Slashdot about how 4.8 was giving people trouble. So I installed 4.7. Worked fine.
I linked out/native/d8 to a location which is in my PATH. This is because the linux-tick-processor script does a poor job at finding d8. The simplest solution was to make it available in my PATH. Your mileage may vary.
After all this, linux-tick-processor can be used with the v8.log files that Node produces.
Either install the source package - sudo apt-get source nodejs, or switch to the official source as the ubuntu packages are very out of date.
To build d8, go to the deps/v8 directory.
Create a symlink at build/gyp to the directory where gyp can be found (e.g. /usr/bin).
Run make native.
Copy/symlink out/native/d8 to somewhere on your PATH.
This might be more of a CYGWIN question than a Nodejs but here goes.
I installed Cygwin yesterday and on the packages selection I just clicked next as it looked like most were pre-selected, and then today read this guide http://boxysystems.com/index.php/step-by-step-instructions-to-install-nodejs-on-windows/ on installing nodejs.
The ./configure had an error that it was unable to remap python lib-dynload/itertools.dll to same address as parent. As the process still completed I tried the make command, but it fails on the same error.
So, I opened cygwin setup.exe and this time I clicked the source checkbox for all the Python packages. But still get the same error. Should I now go to Cygwin and check all the source packages for the Make packages, delete it and reinstall from scratch using the above guide. Or something else?
Any help gratefull received/
Use the official 0.5.x windows build from http://nodejs.org/#download - you just have to download a .exe file and you can start it.
Versions 0.5.X have problems with Cygwin and because of developing clean Windows version Cygwin environment is now unsupported. Stable version 0.4.12 builds on Cygwin with no problems. If you want to use node.js unstable 0.5.X branch on Windows use windows build at official node.js site.
check this out:
https://github.com/joyent/node/wiki/Building-node.js-on-Cygwin-(Windows)
Update Sept 1, 2011 -- as of today, v0.5.5 does not build on Cygwin (errors on make). Use v.0.5.4 (ie. follow instructions below and use "git checkout v0.5.4".
https://github.com/joyent/node/wiki/API-changes-between-v0.4-and-v0.6
Cygwin build is no longer supported. Use native windows builds instead.
