I'm trying to install a font for use with TCPDF. To do so, I need to run the included command line utility ttf2ufm. (Included with TCPDF in fonts/utils/ttf2ufm) When I run it though, I get the error -bash: ttf2ufm: command not found. I'm probably just overlooking something simple, but I've searched and can't find what I'm missing here.
Should mention I'm using Debian Lenny.
Perhaps you do not know how commands are executed in bash.
If the program is not in the path, you need to specify the path to get it to run.
If you are in the right directory.
.../fonts/utils/ $ ./ttf2ufm ....
Note the ./ in front of it, that gives the file a path, in the present working directory, or the full path will work, or any other relative path. Just using ttf2ufm on its own will not, as the current directory is not usually part of the executable path.
Additionally, the program will need its executable bit set.

I've been reading about building RPMs, and the process is quite complex. Is there any program/software that works like this:
Download tar.gz file. Extract to directory
cd into directory
Run
RPM file is output into the directory
Does any such program exist? It seems as if it should. After all, when I run make, make install etc, I don't need to specify spec files, provide locations for where the software has to be installed. So why should I have to do all that for creating RPMs?
I've tried using checkinstall, but I keep getting errors like "Directory not found: /root/rpmbuild/BUILDROOT/hello-2.10-1.x86_64/usr"
So is there an easier way?
No. There is no easier way.
Sometimes upstream provide 'make rpm' target. Sometime checkinstall works. But often you have to create the spec file manually.
BTW that error from checkinstall reveals two things:
you are running that command as root. That is very very unwise.
you should create few build directories. Run command rpmdev-setuptree it will create them for you.
Download binary packages on https://www.playframework.com/documentation/2.0/Installing gives me a play-2.0 folder with play exec file. However running play on that same directory using console returns
play: command not found
My environment is MAC and I tried
chmod a+x play
while running into the same problem
Can someone give me a guide on the installation process?
When we run a command, the shell look for this file (command) in a list of directories (folders). This list of directories is stored in a enviroment variable called PATH. If you want to see the values inside PATH. You can run:
echo $PATH
Note that the folders are separated by :.
The problem you are facing is because the shell can't find a dir that contains the file play. This happens because the play's dir is not in PATH
You can add play's dir to your PATH by running
export PATH=$PATH:/path/to/your/play/dir
This is a temporary thing. After you exit your shell session you will loose it. To make it permanent you need to edit the .bash_profile file in your home folder and add this command in the end of the file and save it.
I have installed a xampp portable package on my drive D, added the php folder path inside it on the system environment so I would be able to run php basically anywhere from the command line. but when i try to check if its working by executing the "php -v" command, it runs but i get this following error/warning messages.
"Warning: PHP Startup: Unable to load dynamic library 'xampp-portable\php\ext[:any].dll - The specified module could not be found."
*the [:any] there just means some dll filename.
and i get a lot of that warnings with just varying dll filenames,
anyway, here's the catch. when i do change my current path in the command line to somewhere in drive D, and then run the same command "php -v" it runs smoothly.
so what configuration should i do to fix this problem?
by the way, i do the same with mysql, putting its bin directory path on the system enviroment, run it in both inside drive C and drive D. and it runs smoothly. so i guess this problem is only on php.
I've posted the same question in xampp forums and this is the answer that was given to me. I'll be quoting the answer as it was and give credit to the one who answere it.
XAMPP is very proud that it don't have to set any environment
variables or registry values.
What you want to do is not possible with XAMPP portable without
mapping to a specific Drive letter. All configurations in xampp
portable have relative paths, so if you want to use cli from a
different drive letter, php can be executed, but all extensions of
them throw errors.
I would install the full version of XAMPP, map it to the current drive
letter with help of the setup_xampp.bat file and use the XAMPP control
panel Shell instead of default command line (advantage: The XAMPP
control panel shell sets local include paths to the needed XAMPP
folders).
Works for me (i can even use pear, git, composer, and other cli
scripts with the Xampp Shell if correct integrated).
best wishes, Altrea

Open your php.ini file, replace all relative paths to absolute paths. Eg: \xampp\ to C:\xampp\
I use cpan to install Carton. When I run this command first, the output is URL can't found. When I run this command second, the output is follows:
Going to read '/home/hengaini/.cpan/Metadata'
Warning: Cannot install Carton, don't know what it is.
Try the command
i /Carton/
to find objects with matching identifiers.
I think the file /home/hengaini/.cpan/Metadata can edit manual or by some tool to go back the first enrionment.
What's the problems.
If you show us the complete output of the cpan command, we might be able to help better.
In this case, I'd just delete everything in the .cpan directly and try again. cpan will fetch everything it needs.
I want to build html docs using a virtualenv instead of the native environment on my machine.
I've entered the virtualenv but when I run make html I get errors saying the module can't be imported - I know the errors are due to the module being unavailable in my native environment.
How can I specify which environment should be used when searching for docs (eg the virtualenv)?
The problem is correctly spotted by Mathijs.
$ which sphinx-build
/usr/local/bin/sphinx-build
I solved this issue installing sphinx itself in the virtual environment.
With the environment activated:
$ source /home/migonzalvar/envs/myenvironment/bin/activate
$ pip install sphinx
$ which sphinx-build
/home/migonzalvar/envs/myenvironment/bin/sphinx-build
It seems neat enough.
The problem here is that make html uses the sphinx-build command as a normal shell command, which explicitly specifies which Python interpreter to use in the first line of the file (ie. #!/usr/bin/python). If Python gets invoked in this way, it will not use your virtual environment.
A quick and dirty way around this is by explicitly calling the sphinx-build Python script from an interpreter. In the Makefile, this can be achieved by changing SPHINXBUILD to the following:
SPHINXBUILD = python <absolute_path_to_sphinx-build-file>/sphinx-build
If you do not want to modify your Makefile you can also pass this parameter from the command line, as follows:
make html SPHINXBUILD='python <path_to_sphinx>/sphinx-build'
Now if you execute make build from within your VirtualEnv environment, it should use the Python interpreter from within your environment and you should see Sphinx finding all the goodies it requires.
I am well aware that this is not a neat solution, as a Makefile like this should not assume any specific location for the sphinx-build file, so any suggestions for a more suitable solution are warmly welcomed.
I had the same problem, but I couldn't use the accepted solution because I didn't use the Makefile. I was calling sphinx-build from within a custom python build file. What I really wanted to do was to call sphinx-build with the exact same environment that I was calling my python build script with. Fiddling with paths was too complicated and error prone, so I ended up with what seems to me like an elegant solution, which is to "manually" load the console script entry point and call it:
from pkg_resources import load_entry_point
cmd = load_entry_point('Sphinx', 'console_scripts', 'sphinx-build')
cmd(['sphinx-build', basepath, destpath])
