I'm on Mac OS X Mountain Lion and a newbie to autotools and other GNU build tools. I'm trying to build a custom version of json-c to use with a a C project (axis2/c). After running the auto tools, and I run the configure command I get a failure with this output:
checking whether to use JSON... yes
checking for JSON... no
configure: error: Package requirements (json) were not met:
No package 'json' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables JSON_CFLAGS
and JSON_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
If I install json-c from macports, configure runs properly. Unfortunately, the project needs a later version of json-c, than what is available in macports (even though this is successful in the configure stage, it later results in a compilation error).
When I install this manually from source, I see that the libs are there in /usr/local/lib and header files in /usr/local/include/json-c. After removing any json-c files that came from macports, I tried copying these repective to the locations in /opt/local/lib and /opt/local/include/json-c but it still resulted in the same package not found error.
What does macports do differently that the package is 'found' when you run configure? Can I replicate the same when I manually install json-c from source?
Thanks in advance.
