Hello, I am trying to build a stripped down python 3.8 wheel from tag apache- arrow-3 <https://issues.apache.org/jira/browse/ARROW-3>.0.0. I am building it using
docker-compose run -e PYTHON=3.8 -e PYTHON_VERSION=3.8 python-wheel-manylinux-2014 however, it is being built using python 3.6. The final wheel gets tagged with pyarrow-3.0.0-cp36-cp36m-manylinux2014_x86_64.whl and looking through the build log I can see that cmake decides to use python 3.6 even though python 3.8 is available in the manylinux image. cmake -DARROW_BROTLI_USE_SHARED=OFF -DARROW_BUILD_SHARED=ON -DARROW_BUILD_STATIC=OFF -DARROW_BUILD_TESTS=OFF -DARROW_DATASET=ON -DARROW_DEPENDENCY_SOURCE=SYSTEM -DARROW_DEPENDENCY_USE_SHARED=OFF -DARROW_FLIGHT==OFF -DARROW_GANDIVA=OFF -DARROW_HDFS=OFF -DARROW_JEMALLOC=ON -DARROW_MIMALLOC=ON -DARROW_ORC=OFF -DARROW_PACKAGE_KIND=manylinux2014 -DARROW_PARQUET=ON -DARROW_PLASMA=OFF -DARROW_PYTHON=ON -DARROW_RPATH_ORIGIN=ON -DARROW_S3=OFF -DARROW_TENSORFLOW=OFF -DARROW_USE_CCACHE=ON -DARROW_UTF8PROC_USE_SHARED=OFF -DARROW_WITH_BROTLI=OFF -DARROW_WITH_BZ2=OFF -DARROW_WITH_LZ4=ON -DARROW_WITH_SNAPPY=ON -DARROW_WITH_ZLIB=ON -DARROW_WITH_ZSTD=ON -DCMAKE_BUILD_TYPE=release -DCMAKE_INSTALL_LIBDIR=lib -DCMAKE_INSTALL_PREFIX=/tmp/arrow-dist -DCMAKE_TOOLCHAIN_FILE=/opt/vcpkg/scripts/buildsystems/vcpkg.cmake -DCMAKE_UNITY_BUILD=OFF -DOPENSSL_USE_STATIC_LIBS=ON -DThrift_ROOT=/opt/vcpkg/installed/x64-linux/lib -DVCPKG_TARGET_TRIPLET=x64-linux-static-release -G Ninja /arrow/cpp -- Building using CMake version: 3.19.2 -- The C compiler identification is GNU 9.3.1 -- The CXX compiler identification is GNU 9.3.1 -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working C compiler: /opt/rh/devtoolset-9/root/usr/bin/cc - skipped -- Detecting C compile features -- Detecting C compile features - done -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Check for working CXX compiler: /opt/rh/devtoolset-9/root/usr/bin/c++ - skipped -- Detecting CXX compile features -- Detecting CXX compile features - done -- Arrow version: 3.0.0 (full: '3.0.0') -- Arrow SO version: 300 (full: 300.0.0) -- clang-tidy not found -- clang-format not found -- Could NOT find ClangTools (missing: CLANG_FORMAT_BIN CLANG_TIDY_BIN) -- infer not found -- Found Python3: /opt/python/cp36-cp36m/bin/python3.6 (found version "3.6.12") found components: Interpreter Am I missing some config to make it build a python 3.8 wheel? Thanks.
