I am trying to compile Apache 2.4.25 on Fedora 25 Linux. The current version of nghttp2 is installed: ----------------------------- [John@prod04 httpd-2.4.25]$ rpm -qv nghttp2 nghttp2-1.13.0-2.fc25.x86_64 ----------------------------- ----------------------------- /usr/lib64/libnghttp2.so.14 /usr/lib64/libnghttp2.so.14.9.0 ----------------------------- To me, these would both seem to be greater than 1.2.1, but I am getting this error from configure: ---------------------------------------------- checking for nghttp2... checking for user-provided nghttp2 base directory... none checking for pkg-config along ... checking for nghttp2 version >= 1.2.1... FAILED configure: WARNING: nghttp2 version is too old no checking whether to enable mod_http2... configure: error: mod_http2 has been requested but can not be built due to prerequisite failures ------------------------------------------------ These are the currently available versions from the Fedora repository. Has anyone any suggestions as to why this might be occurring? Thanks in advance.
