--------------------------------
Summary: [C++/Python] pyarrow build incorrectly detects x86 as
system process during cross-cimpile
Key: ARROW-15445
URL: https://issues.apache.org/jira/browse/ARROW-15445
Project: Apache Arrow
Issue Type: Bug
Components: C++, Python
Reporter: Uwe Korn
When cross-compiling {{pyarrow}} for aarch64 or ppc64le we run into the
following issue:
{code:java}
-- System processor: x86_64
-- Performing Test CXX_SUPPORTS_SSE4_2
-- Performing Test CXX_SUPPORTS_SSE4_2 - Failed
-- Performing Test CXX_SUPPORTS_AVX2
-- Performing Test CXX_SUPPORTS_AVX2 - Failed
-- Performing Test CXX_SUPPORTS_AVX512
-- Performing Test CXX_SUPPORTS_AVX512 - Failed
-- Arrow build warning level: PRODUCTION
CMake Error at cmake_modules/SetupCxxFlags.cmake:456 (message):
SSE4.2 required but compiler doesn't support it.
Call Stack (most recent call first):
CMakeLists.txt:121 (include)
-- Configuring incomplete, errors occurred!
{code}
The error is valid as we are building for a target system that doesn't support
SSE at all.
