The changelog entry for last change to the civetweb package says:

enable -DCIVETWEB_ENABLE_WEBSOCKETS and -DCIVETWEB_ENABLE_X_DOM_SOCKET

However, checking the available features in the library using a tiny test program:

$ cat civetweb_check_features.c
#include "civetweb.h"
int main()
{
    printf("%x\n", mg_check_feature(MG_FEATURES_ALL));
    return 0;
}
$ gcc civetweb_check_features.c -lcivetweb
$ ./a.out 
9f

I.e. MG_FEATURES_WEBSOCKET (0x10u) is available in the library, but MG_FEATURES_X_DOMAIN_SOCKET (0x800u) is not.

The civetweb source provides two different build systems: plain makefiles and cmake. Providing more than one build system introduces a risk that they diverge, which has happened here: in the released version 1.16 the plain makefiles support enabling X_DOM_SOCKET, but cmake does not. Since the Fedora and RHEL builds use cmake the option, though present in the cmake command line in the spec file, is not propagated to the build. The missing lines in the CMakeLists.txt have since been added in a commit to the upstream github repo:

https://github.com/civetweb/civetweb/commit/08b7241f4bce808c3a932a5fddc1181acee5c0c1

Adding a patch based on this commit fixes the problem.

An additional point:

According to the changelog the last change was made to allaw root to be built using the system civetweb. As the maintainer of the root package I welcome this step. However, in the current master branch in the root github repo, the check for a good system civetweb library checks for three features:

https://github.com/root-project/root/blob/58786cc3783e90f0afa7a5529f8d206c48a2453d/cmake/modules/SearchInstalledSoftware.cmake#L587

CIVETWEB_HAS_WEBSOCKET, CIVETWEB_HAS_ZLIB amd CIVETWEB_HAS_X_DOM_SOCKET.

I would therefore like to request that the ZLIB compression option is enabled in the build as well.

Wirh these changes the test program above returns:

$ LD_LIBRARY_PATH=./usr/lib64 ./a.out 
a9f

I.e. all of MG_FEATURES_WEBSOCKET (0x10u), but MG_FEATURES_X_DOMAIN_SOCKET (0x800u)
and MG_FEATURES_COMPRESSION (0x200u) are available in the library.

civetweb ia currently retired in rawhide, with the stated reason: "unused by any packages". With the fixes proposed in this bugreport this would not be true any more, since it would be used to build the root package. I would therefore like to request that the package is unretired.

How can these changes be forwarded to the RHEL packages as well?

Reproducible: Always

Steps to Reproduce:
1. See test program in Details above

Actual Results:
X_DOM_SOCKET not supported.

Expected Results:
X_DOM_SOCKET (and ZLIB compression) supported.
