pyinstaller no predefined compiler for raspberry pi

Question

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?

Full Tutorial

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.

Key Takeaways

• pip ships PyInstaller with the incorrect architectures. You need to build it yourself for ARM (Raspberry Pi).

Step by Step

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

Debugging

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
