Description

libmicrohttpd v0.9.74 marks some definitions as deprecated, which leads to compiler warnings when using them, which libhttpserver does. This leads to build failure when calling configure with --enable-debug because that adds -Werror to compiler flags.

Steps to Reproduce

1. Build libmicrohttpd v0.9.74 or v0.9.75
2. Call ../configure with --enable-debug
3. Call make

Expected behavior: Successful build.

Actual behavior: Build fails.

Reproduces how often: Always.

Versions

• OS version: Debian GNU/Linux 10 (buster)
• libhttpserver version: master
• libmicrohttpd version: v0.9.75, compiled

If you have problems during build:

• Compiler version: gcc (Debian 8.3.0-6) 8.3.0
• autotools version: ??

Additional Information

The deprecated definitions are these:

• MHD_HTTP_UNORDERED_COLLECTION
• MHD_HTTP_PAYLOAD_TOO_LARGE
• MHD_HTTP_UNPROCESSABLE_ENTITY
