After install

[JeffHoover]

Following the the steps in INSTALL.md on my raspberry pi (specs at the end of this issue), when I run make, I get an error (see below) that looks like maybe jansson wasn't installed correctly (although it appears to be, at /usr/share/doc/libjansson4/).

I thought at first it was because I had done the apt-get of the dependencies with sudo instead of as root. So I did remove, then su'ed to root, then did the apt-get again and exited. Make still gave me the error:

$ make cd lib/orcania && make make[1]: Entering directory '/home/pi/ulfius/lib/orcania' gcc -c -fPIC -Wall -D_REENTRANT -O3 orcania.c orcania.c: In function ‘json_search’: orcania.c:273:5: warning: implicit declaration of function ‘json_array_foreach’ [-Wimplicit-function-declaration] orcania.c:273:49: error: expected ‘;’ before ‘{’ token Makefile:35: recipe for target 'orcania.o' failed make[1]: *** [orcania.o] Error 1 make[1]: Leaving directory '/home/pi/ulfius/lib/orcania' Makefile:45: recipe for target 'libulfius.so' failed make: *** [libulfius.so] Error 2

Debian GNU/Linux 7.11 (wheezy)

I've updated the firmware, and I've done sudo apt-get update and 'sudo apt-get upgrade' as well.

It looks like you don't have libjansson-dev installed.

$ sudo apt-get install libjansson-dev 

Should do the trick, let me know if you still have the same problem after

Seems like it is already installed. See below. (Sorry I can't figure out the markdown formatting)

Maybe the latest version isn't the one I need? Here's what the install said (after I did the remove):

I think I got it, you use raspbian wheezy which has libjansson 2..3 in it, although in this version, there is no json_array_foreach macro.

You can update to raspbian jessie or install manually the last libjansson library. I'll add a note in the INSTALL.md file to prevent it, thanks.

I understand! :D Apparently *upgrading* to jessie is treacherous - I already ordered an SD with jessie pre-installed. Meanwhile, I'll try building and installing libjansson. Thanks for the link! Thank you! Jeff

I never upgraded from wheezy to jessie on a raspbian, but I flashed jessie images on sd-cards like billions of times, works like a charm :)

Installation worked fine on my new Jessie image. Thanks again for your help!
