I had 'json-c.x86_64' and 'json-devel.x86_64' installed.  On your suggestion I searched for json-c and installed 'json-c-devel.x86_64'.  That's what was needed.  Thanks for the nudge in the right direction.  After install of 'perl-XML-LibXML.x86_64', 'flex.x86_64', and 'bison' it compiled.

Hi All,

We've been using Quagga for a while and looking forward to switching over to FRR.  I'm having trouble compiling on Centos 7 though.  When I attempt to compile I get this error:

checking whether to build static libraries... yes checking json-c/json.h usability... no checking json-c/json.h presence... no checking for json-c/json.h... no checking for json_object_get in -ljson-c... no checking for json_object_get in -ljson... no configure: error: lib json is needed to compile

I see the header and c file in the lib folder:

[centos@ip-172-30-5-42 frr-frr-3.0.2]$ find ./ -name json.* ./lib/json.c ./lib/json.h [centos@ip-172-30-5-42 frr-frr-3.0.2]$

I have json libs installed on my machine:

[centos@ip-172-30-5-42 frr-frr-3.0.2]$ yum list installed | grep json json-c.x86_64 0.11-4.el7_0                   installed json-devel.x86_64 0-4.20150410gitd7d0509.el7     @epel json-glib.x86_64 1.2.6-1.el7                    @base json-glib-devel.x86_64 1.2.6-1.el7                    @base libfastjson.x86_64 0.99.4-2.el7                   @base python-jsonpatch.noarch 1.2-4.el7                      @base python-jsonpointer.noarch 1.9-2.el7 installed [centos@ip-172-30-5-42 frr-frr-3.0.2]$

What am I missing?  Thanks for any help.
