I can build swupdate without suricatta but when I enable it, fails to find -ljson-c.
I am using ubuntu 20.04 and yocto kirkstone, with an A55 processor.
The problem is normally that libjson-c-dev has not not being installed using apt. This is not the case, I can see the headers and the libraries.
This is the cmdline used by bitbake

This is the error shown, it cannot find libjson.

cannot find -ljson-c: No such file or directory`
I have checked the headers and libs are installed
find /usr/lib -name libjson*
/usr/lib/x86_64-linux-gnu/libjson-c.a
/usr/lib/x86_64-linux-gnu/libjson-c.so.4
/usr/lib/x86_64-linux-gnu/libjson-c.so.4.0.0
/usr/lib/x86_64-linux-gnu/libjson-c.so
I have checked the search path and that matches the path for the libjson-c libs.
ld --verbose | grep SEARCH_DIR | tr -s ' ;' \\012
SEARCH_DIR("=/usr/local/lib/x86_64-linux-gnu")
SEARCH_DIR("=/lib/x86_64-linux-gnu")
SEARCH_DIR("=/usr/lib/x86_64-linux-gnu")
SEARCH_DIR("=/usr/lib/x86_64-linux-gnu64")
SEARCH_DIR("=/usr/local/lib64")
SEARCH_DIR("=/lib64")
SEARCH_DIR("=/usr/lib64")
SEARCH_DIR("=/usr/local/lib")
SEARCH_DIR("=/lib")
SEARCH_DIR("=/usr/lib")
SEARCH_DIR("=/usr/x86_64-linux-gnu/lib64")
SEARCH_DIR("=/usr/x86_64-linux-gnu/lib")
I have checked the libraries are in the correct format.
I checked libcrypt and libjson-c library as libcrpt is found and is in the same directory as libjson-c.
objdump -h /usr/lib/x86_64-linux-gnu/libjson-c.a
file format elf64-x86-64
objdump -h /usr/lib/x86_64-linux-gnu/libcrypt.a
file format elf64-x86-64
Can anybody suggest how to analyse why it is not finding this one library ?
