Description (last modified by bullerdu@…)

Test zlib-ng feature 'Gzip: support for zlib-ng.' https://hg.nginx.org/nginx/rev/1f3d0d9f893f

Downdload zlib-ng from https://github.com/zlib-ng/zlib-ng.

Then do configure ./configure --prefix=/home/yefei.dyf/nginx --with-zlib=/home/yefei.dyf/zlib-ng-2.0.7 --with-cc-opt=-I/home/yefei.dyf/boringssl/include --with-ld-opt='-L/home/yefei.dyf/boringssl/ssl -L/home/yefei.dyf/boringssl/crypto'

The compile error is as follows.

Resolution:	→ invalid
Status:	new → closed

The zlib-ng library is a different library, not zlib, so trying to instruct nginx to build it by using --with-zlib= configure option is expected to fail.

Instead, consider building zlib-ng yourself. If it's not installed system-wide, make sure to provide appropriate include and library dirs with --with-cc-opt="-I /path/to/zlib-ng/include" and --with-ld-opt="-L /path/to/zlib-ng/lib" when building nginx. Alternatively, load it with LD_PRELOAD when starting nginx compiled with zlib.

Note well that you'll have to build zlib-ng with zlib compatibility, --zlib-compat. Please refer to zlib-ng documentation for more details.

Note: See TracTickets for help on using tickets.
