I want to convert myscript.py to a exexutable file. i am using raspberry pi(raspbian) and python 2.7.
I am issuing the following command
sudo pip install PyInstaller
sudo pyinstaller myscript.py
after some processing it provides an error
Fatal error: PyInstaller does not include a pre-compiled bootloader for your
platform. See <http://pythonhosted.org/PyInstaller/#building-the-bootloader>
for more details and instructions how to build the bootloader.
i go online to build compiler but could not understand the process. how could i solve this problem?

First, I have successfully installed PyInstaller on my Raspberry using pip -> "sudo pip install pyinstaller", and after I compiled one of my files that uses Python2. 7 using "sudo pyinstaller --onefile my_file.py". The result is great and everything worked.
The most common reason a PyInstaller package fails is that PyInstaller failed to bundle a required file. Such missing files fall into a few categories: Hidden or missing imports: Sometimes PyInstaller can't detect the import of a package or library, typically because it is imported dynamically.
PyInstaller bundles a Python application and all its dependencies into a single package. The user can run the packaged app without installing a Python interpreter or any modules. PyInstaller reads a Python script written by you.
pip will install PyInstaller's dependencies along with a new command: pyinstaller . PyInstaller can be imported in your Python code and used as a library, but you'll likely only use it as a CLI tool. You'll use the library interface if you create your own hook files.
But a google search revealed that pip install installes the wrong type of requirements. My project needs pygame module to work and also imports time, random and copy modules. The project is also spread across many files. Pyinstaller supports Linux but does it support raspbian on raspberry pi ARM core.
PyInstaller reads a Python script written by you. It analyzes your code to discover every other module and library your script needs in order to execute. Then it collects copies of all those files – including the active Python interpreter! – and puts them with your script in a single folder, or optionally in a single executable file.
PyInstaller is available on PyPI. You can install it through pip: tinyaes 1.0+ (only if using bytecode encryption). Instead of installing tinyaes, pip install pyinstaller [encryption] instead. PyInstaller should work on Windows 7 or newer, but we only officially support Windows 8+.
If it does not say ELF 32-bit LSB executable, ARM, but instead says Intel or x86, the PyInstaller tries to use the incorrect bootloader. If you executed all steps above, try renaming the Linux-32bit-arm to just Linux-32bit. That seems to have worked for this user.
After many hours of searching, I got this working. The answer is straightforward, but it is spread across multiple StackExchange answers and GitHub Issues. I put it all together in this tutorial, so I save some hours for the next poor soul.
pip ships PyInstaller with the incorrect architectures. You need to build it yourself for ARM (Raspberry Pi).1. Build the bootloader
git clone https://github.com/pyinstaller/pyinstaller
# Alternatively download the zip from https://github.com/pyinstaller/pyinstaller/releases
cd pyinstaller/bootloader
python ./waf distclean all # or python3
cd ../PyInstaller/bootloader/
ls
Here you should see Linux-32bit-arm and inside of it run and run_d
2. Check the bootloader
file Linux-32bit-arm/run
run: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0, BuildID[sha1]=a01c65d74d7d8b483800154dcdd4a5d2aad95d5b, stripped
If you see the above, you are good so far. However, if you see something like ELF 32-bit LSB executable, Intel 80386, that is wrong.
3. Copy the bootloader
If you installed PyInstaller with pip inside a venv, then do this
# Replace ${CLONED_PYINSTALLER_PATH} with the path where you git cloned above
# Replace ${PATH_TO_YOUR_PROJECT} with the path to your project (where you have the venv)
cp -r ${CLONED_PYINSTALLER_PATH}/PyInstaller/bootloader/Linux-32bit-arm ${PATH_TO_YOUR_PROJECT}/venv/lib/python3.5/site-packages/PyInstaller/bootloader/
If you installed with apt-get, then do this
# !!! Replace python3.5 with your version
cp -r ${CLONED_PYINSTALLER_PATH}/PyInstaller/bootloader/Linux-32bit-arm /usr/local/lib/python3.5/dist-packages/PyInstaller/bootloader
Issue
SystemError: objcopy Failure: objcopy: Unable to recognise the format of the input file `$FILE`
Check
`file dist/$FILE`
If it does not say ELF 32-bit LSB executable, ARM [...], but instead says Intel or x86, the PyInstaller tries to use the incorrect bootloader. If you executed all steps above, try renaming the Linux-32bit-arm to just Linux-32bit. That seems to have worked for this user
Issue
gcc not found
