[GitHub] [arrow] Yuhta opened a new issue, #13367: How to build without PIC
Yuhta opened a new issue, #13367:
URL: https://github.com/apache/arrow/issues/13367
I try to build a static library without PIC, and cannot find a way to do so.
I am setting these options in cmake `-DARROW_BUILD_SHARED=off -DARROW_CXXFLAGS=-fno-PIC`, but when the build actually happening, a `-fPIC` is automatically appended after `ARROW_CXXFLAGS`:
```

```
I looked around in the cmake and cannot find where the last `-fPIC` gets appended. Can you point me a way to remove that flag?

Thanks @kou , our company has the policy that every library must be build for both PIC and non-PIC version, non-PIC version is for performance optimization. It would be nice to have a flag to optionally disable PIC in the build.

We always set `CMAKE_POSITION_INDEPENEDNT_CODE` to `ON` in `cpp/cmake_modules/*.cmake`.
You need to change `*.cmake` files to set `CMAKE_POSITION_INDEPENDENT_CODE` to `OFF` for now because we don't provide option to control it.
BTW, why do you want to disable PIC?

OK. Could you open an issue on https://issues.apache.org/jira/browse/ARROW as a feature request?
