- Subject: [PATCH] configure.ac: add --disable-werror
- Allow the user to disable -Werror to avoid the following build failure:
- In file included from hash.c:7:
- xxhash.h:2667:5: error: #warning is a GCC extension [-Werror]
- 2667 | # warning "XXH3 is highly inefficient without ARM or Thumb-2."
- | ^~~~~~~
- xxhash.h:2667:5: error: #warning "XXH3 is highly inefficient without ARM or Thumb-2." [-Werror=cpp]
- Fixes:
