Karl Dunkle Werner created ARROW-14210: ------------------------------------------
Summary: [C++] CMAKE_AR is not passed to bzip2 thirdparty dependency Key: ARROW-14210 URL: https://issues.apache.org/jira/browse/ARROW-14210 Project: Apache Arrow Issue Type: Bug Components: C++ Affects Versions: 5.0.0 Reporter: Karl Dunkle Werner It seems like the {{AR}} or {{CMAKE_AR}} variables aren't getting passed for the bzip2 build, which causes if to fail if we're doing a {{BUNDLED}} build and {{ar}} isn't available in the {{$PATH}} (e.g. in a conda environment). To replicate: 1. Download Arrow and start an interactive shell in a container (docker should be fine if you prefer it to podman) {code:sh} git clone --depth 1 g...@github.com:apache/arrow.git podman run -it --rm -v ./arrow:/arrow:Z docker://ursalab/amd64-ubuntu-18.04-conda-python-3.6:worker bash {code} 2. Build Arrow by running this in in the container: {code:sh} export ARROW_BUILD_TOOLCHAIN=$CONDA_PREFIX export ARROW_HOME=$CONDA_PREFIX export PARQUET_HOME=$CONDA_PREFIX cd /arrow mkdir -p cpp/build pushd cpp/build cmake \ -DCMAKE_BUILD_TYPE=$ARROW_BUILD_TYPE \ -DCMAKE_INSTALL_PREFIX=$ARROW_HOME \ -DCMAKE_AR=${AR} \ -DCMAKE_RANLIB=${RANLIB} \ -DARROW_WITH_BZ2=ON \ -DARROW_VERBOSE_THIRDPARTY_BUILD=ON \ -DARROW_JEMALLOC=OFF \ -DARROW_SIMD_LEVEL=NONE -DARROW_RUNTIME_SIMD_LEVEL=NONE \ -DARROW_DEPENDENCY_SOURCE=BUNDLED \ .. make # make[3]: ar: No such file or directory # make[3]: *** [Makefile:48: libbz2.a] Error 127 # make[2]: *** [CMakeFiles/bzip2_ep.dir/build.make:135: bzip2_ep-prefix/src/bzip2_ep-stamp/bzip2_ep-build] Error 2 # make[1]: *** [CMakeFiles/Makefile2:726: CMakeFiles/bzip2_ep.dir/all] Error 2 {code} In the cmake call above, {{ARROW_JEMALLOC}} and the SIMD flags are just to skip compiling irrelevant things. I think this line in {{ThirdpartyToolchain.cmake}} needs to be changed to pass {{CMAKE_AR}}. [https://github.com/apache/arrow/blob/bad8824d5cda0fd8337c7167729c49af868f93a5/cpp/cmake_modules/ThirdpartyToolchain.cmake#L2211] Other related issues have also needed to pass {{CMAKE_RANLIB}}, in addition to {{CMAKE_AR}}. I'm not sure if that applies here. Related: ARROW-4471, ARROW-4831 -- This message was sent by Atlassian Jira (v8.3.4#803005)
