---------------------------------------
Summary: [C++] Disable color diagnostics when compiling with ccache
Key: ARROW-14436
URL: https://issues.apache.org/jira/browse/ARROW-14436
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Krisztian Szucs
Fix For: 7.0.0
Copied from https://github.com/apache/arrow/issues/11279
Steps to reproduce:
Compile arrow_objlib with ccache, clang and CCACHE_DEBUG=1
CCACHE_LOGFILE=./ccache.log
Find in ./ccache.log:
Failed; falling back to running the real compiler
Result: unsupported compiler option
Dropping -fcolor-diagnostics fixes the issue.
I suggest either opting into color diagnostics with WITH_COLOR_DIAGNOSTICS or
adding a way to disable it via DISABLE_COLOR_DIAGNOSTICS.
It would be good if this wouldn't be tied to ARROW_USE_CCACHE since its also
relevant for:
-DARROW_USE_CCACHE=OFF -DCMAKE_CXX_COMPILER_LAUNCHER=emscripten_ccache.
I can open a PR if you tell me which way you prefer.
