[users@httpd] Error nghttp2 version is too old
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.
John

I solved this one and it had nothing to do with the version of the nghttp
library.
I did not have the development environment for nghttp installed.
Installing libnghttp2-devel.x86_64 resolved the problem and the compilation
ran to completion.
[The following applies specifically to Fedora 25; I don't know if it is
applicable to other current distros.]
For what it's worth, this is the second time I have got caught this way on
this project. Last time it was pcre. Installing the programme using dnf
(replacement for rpm/yum) doesn't also install the development components,
if any. You can find out if any exist by running 'dnf search name' and if
name-devel exists it will be listed.

John

Just prints the "Checking..." message. The actual check is below -
compilation of some snippet.
> AC_TRY_COMPILE([#include <nghttp2/nghttp2ver.h>],[
If compilation and test succeed then the following assignment happens:
"ac_cv_nghttp2=yes".
Apparently the compilation and test failed, and the variable was not assigned.
The following block

The "if" branch was skipped and "else" branch printed the warning.
I suggest you to check what is the actual value of NGHTTP2_VERSION_NUM.
> checking for user-provided nghttp2 base directory...
Try to specify the path explicitly,
--with-nghttp2=PATH

Re: [users@httpd] Error nghttp2 version is too old
Posted by John Iliffe <jo...@iliffe.ca>.
I'm not sure it is evident that there is a question buried in the note
below so here is a precis of what I asked:
1. the requirement is for nghttp2 at level 1.2.1 whereas I have nghttp2
1.13.0 installed. Why is that considered lower than the requirement?
2. assuming (always a bad idea) that the problem is that the compiler is
checking for some specific link in the nghttp2 library, is it likely that
what I really need to do is install a back level, and if so, any idea what
it is looking for? ..or what back level is required?
Sorry for the confusion.

OK, I will have to see what I can do with Fedora, probably not much in
this case.
My question though was that the version I have is 1.13.0 according to
rpm. That would seem to be higher than 1.2.1 so why would the compiler
complain? I assume that it has an internal requirement on the library
that it didn't find?
In that case it might be necessary to back off a few levels to find
whatever the compiler wants?

John

You really need to approach your package maintainer, I picked up
nghttp2 around that same point a year ago and never had an issue.
Anything to do with rpm installs is on the maintainer, and has nothing
to do with this project, sorry we can't be of more help.
