# Proposed changes
Add an environment variable `EXTRA_CXX_FLAGS` to customize the extra compile
flags.
## Problem summary
In our daily work, someones may want to change the compile flags to satisfy
their requirements. This pr introduces a way to customize extra compile flags.
E.g.
Change the optimization level:
```shell
BUILD_TYPE=ASAN EXTRA_CXX_FLAGS=-O3 ./build.sh --be
```
```shell
export EXTRA_CXX_FLAGS=-O3
BUILD_TYPE=ASAN ./build.sh --be
```
```shell
echo EXTRA_CXX_FLAGS=-O3 >> custom_env.sh
BUILD_TYPE=ASAN ./build.sh --be
```
