How do I find the current configured path for make install?
The resources that I have read till now only describe how to overwrite it.
configure creates a file called config.log this contains near the top the configure command with the arguments that was run. You should find your --prefix argument there.
Otherwise grepping for PREFIX should get you a result.
Another solution is to use make -n install which would perform a dry run and print what make install would do without doing it.

Meson/Ninja provide an easy method to run a script at install time.
For example, this line will tell Meson to run the glib-compile-schemas command to compile the GSettings on Linux (system configuration options).
meson.add_install_script('glib-compile-schemas', schemas_dir)
(this command will be automatically run when the user executes ninja install)
How can I tell Meson to run a custom command at uninstall?
In this specific case I would like to delete (or at least reset to default) the key-value pairs in GSettings. To reset them, I have found that the command is gsettings reset-recursively <path> (successfully tested in terminal).
Adding custom uninstall script is still being discussed, it's proposed quite some time ago but not yet implemented. It looks this task is typically left for package manager (and therefore to corresponding packaged scripts).
But I agree, there is some illogical asymmetry in case of meson install command. As a workaround, you can create your own target:
run_target('my-uninstall', command : ['scripts/uninstall.sh'])
The drawbacks, of course, are that it should be invoked explicitly, cannot override, append or rename internal uninstall target and script should have executable permissions.
The internal, reserved uninstall target, however, does revert all explicit install operations:
Meson allows you to uninstall an install step by invoking the
uninstall target. This will remove all files installed as part of
install. Note that this does not restore the original files. This also
does not undo changes done by custom install scripts (because they can
do arbitrary install operations).
I followed the Software Collections Quick Start and I now have Python 3.5 installed. How can I make it always enabled in my ~/.bashrc, so that I do not have to enable it manually with scl enable rh-python35 bash?
Use the scl_source feature.
Create a new file in /etc/profile.d/ to enable your collection automatically on start up:
$ cat /etc/profile.d/enablepython35.sh
#!/bin/bash
source scl_source enable python35
See How can I make a Red Hat Software Collection persist after a reboot/logout? for background and details.
This answer would be helpful to those who have limited auth access on the server.
I had a similar problem for python3.5 in HostGator's shared hosting. Python3.5 had to be enabled every single damn time after login. Here are my 10 steps for the resolution:
Enable the python through scl script python_enable_3.5 or scl enable rh-python35 bash.
Verify that it's enabled by executing python3.5 --version. This should give you your python version.
Execute which python3.5 to get its path. In my case, it was /opt/rh/rh-python35/root/usr/bin/python3.5. You can use this path to get the version again (just to verify that this path is working for you.)
Awesome, now please exit out of the current shell of scl.
Now, lets get the version again through this complete python3.5 path /opt/rh/rh-python35/root/usr/bin/python3.5 --version.
It won't give you the version but an error. In my case, it was
/opt/rh/rh-python35/root/usr/bin/python3.5: error while loading shared libraries: libpython3.5m.so.rh-python35-1.0: cannot open shared object file: No such file or directory
As mentioned in Tamas' answer, we gotta find that so file. locate doesn't work in shared hosting and you can't install that too.
Use the following command to find where that file is located:
find /opt/rh/rh-python35 -name "libpython3.5m.so.rh-python35-1.0"
Above command would print the complete path (second line) of the file once located. In my case, output was
find: `/opt/rh/rh-python35/root/root': Permission denied
/opt/rh/rh-python35/root/usr/lib64/libpython3.5m.so.rh-python35-1.0
Here is the complete command for the python3.5 to work in such shared hosting which would give the version,
LD_LIBRARY_PATH=/opt/rh/rh-python35/root/usr/lib64 /opt/rh/rh-python35/root/usr/bin/python3.5 --version
Finally, for shorthand, append the following alias in your ~/.bashrc
alias python351='LD_LIBRARY_PATH=/opt/rh/rh-python35/root/usr/lib64 /opt/rh/rh-python35/root/usr/bin/python3.5'
For verification, reload the .bashrc by source ~/.bashrc and execute python351 --version.
Well, there you go, now whenever you login again, you have got python351 to welcome you.
This is not just limited to python3.5, but can be helpful in case of other scl installed softwares.
On windows after running the grunt build command for creating brackets shell it gives done without errors but i dont see any .exe file generated..
What might be the problem???
Here are some possible solutions:
Are you following the full brackets-shell build instructions, including all prerequisites?
Make sure Brackets isn't running at the same time. The build will fail silently if the .exe file is currently in use (see bug).
Try with a fresh git clone of the repo. If your brackets-shell local copy has been around for a while, sometimes the build & deps folders can get in a bad state. (I'm assuming you haven't modified the source at all. If you have, try with an unmodified copy of the source first to make sure it builds correctly without any of your changes).
Check that python --version shows 2.7.x
Verbose build output would also be helpful in diagnosing issues like this, but unfortunately there's not yet an easy way to get that...
If you follow the instructions on bracket-shell's wiki page, the Windows executable should be created in the Release directory.
I have an install.bat file and a resource folder. so long as these two files are in the same directory, if you run install.bat, it will install a my lwjgl game. so what im trying to do is make a self extracting file that when completed runs the launch.bat file. I have tried using iexpress, and got it working for the most part. i have added in all my files and such so it will extract to some directory and then i can run the install.bat file to get my program to work. thing is though, i want the exe i created with iexpress to launch install.bat when its finished. so, i tried using the option in iexpress that says it will execute a command when finished the "installation" (using quotes because its not the actual installation, just extracting the files to some directory specified by the user). when i get to the step where it says what i would like to execute during and after the "installation". during the installation i left blank. after the installation i chose the install.bat file. when i try to click next though, it tells me i must choose something for the command during the extraction. I don't have anything specific to do during the installation so i just said "echo." (without quotes). after i was done i tried running the installer. before it even prompted me for a folder to extract to, it told me that echo. could not be executed. so i went back into my installation (via a .sed file) and changed the "echo." to "pause". that didn't work either. i then read on another website that in order to run a file the way i would like to, i put the file name in both the during and after installation boxes. i tried doing that and it didn't work either. can anyone please help me?
If I understood your question correctly you will need to specify what the iexpress must do at the post install command option provided so that cmd.exe is used instead of command.com, eg:
cmd.exe /c filethatyouwanttorun.bat
Refer to the question: Create Batch file for iexpress.
You can use the SED file and then modify the self extraction directive. This will run the batch file that you wanted to run and then install the application. (If you have chosen the option to extract and run an installation in iexpress, a temp folder will be used for the extraction I suppose.)
I'm not sure I understand your question exactly but perhaps a few points would help:
If you want a "do nothing" command, you can use something like:
cmd /c echo.
There is no "command during the extraction". There's only an install program and a post install command. Both of these execute after extraction. If you only need to execute one batch file, put it in the install program line and leave the post install command blank.
You can't ask the user for an extraction path and execute a file. You can only do one or the other. (The install program could prompt the user and copy the files there, though.)
I am trying to start use Symfony2, and i have troubles with a first step.
In the documentation I found
To create a bundle called AcmeHelloBundle (a play bundle that you'll
build in this chapter), run the following command and follow the
on-screen instructions (use all of the default options):
php app/console generate:bundle --namespace=Acme/HelloBundle
> --format=yml
and I really don’t understand where should I write this string? In which program or in which file?
As Molecule Man said, it's a command line thing. But just to give a few more details:
Open up a console window (also called a command prompt in Windows)
Type "php --version" (no quotes). It should come back with a version number. If it says something like "can't find php" then you need to set a path to php.
Change directory to your Symfony directory
Type "php app/console" If everything is working then you will see a list of available commands. There are many things you can do from the command line.
If you happen to be on a unix system then you can make console executable and just use "./app/console"
Now try creating your bundle
