I'm trying to cross-compile a package for openwrt (python3.7, cpu mips). This is what I did to set up the environment: cd build-mipsel/
mkdir build-python host-python wheels
tar zxvf Python-3.7.13.tgz
mv Python-3.7.13 Python-3.7.13-build
tar zxvf Python-3.7.13.tgz
mv Python-3.7.13 Python-3.7.13-host
cd Python-3.7.13-build/
./configure --prefix=$(realpath ../build-python/)
make -j
make install
cd ../Python-3.7.13-host/
PATH=$(realpath ../build-python/)/bin:$PATH ./configure --prefix=$(realpath ../host-python/) --build=x86_64-pc-linux-gnu --host=mipsel-linux-gnu --without-ensurepip ac_cv_buggy_getaddrinfo=no ac_cv_file__dev_ptmx=yes ac_cv_file__dev_ptc=no
PATH=$(realpath ../build-python/)/bin:$PATH make -j
PATH=$(realpath ../build-python/)/bin:$PATH make install
cd ..
build-python/bin/python3 -m crossenv host-python/bin/python3 cross_venv
. ./cross_venv/bin/activate
sudo apt install cmake ninja-build
build-python -m pip install -U pip
build-python -m pip install -U setuptools cmake wheel ninja
pip install -U pip
pip install -U setuptools wheel
pip -v wheel c104 -w wheels/ --no-build-isolationThe last command gives the following errors: Note that the compiler is specified as /usr/bin/c++, instead of the correct one. Perhaps this gives an error due to the bitness. However, if I run the command with the correct compiler: Perhaps I did something wrong or is this a bug in crossenv? |

cmake (and meson) do not detect their compiler from the python installation, but require you to explicitly specify it either via the environment or via a cross-compile file. |
