Dear ALL

It always show some  errors when I configure the mysqljsonload.

when configure the mysqljsonload,it always shows "Jansson library does not exist",though i have already installed the jansson-2.4.

I`m sure the jansson has already installed ,and use "./configure --with-jansson=/usr/local --with-mysql=/var/lib/mysql/" to install themysqljsonload.

The location of jansson & mysql  is correct.

 

I`m not sure ,is there still some mistakes?

Thx a lot .

This is my problem I guess, and I have to look into it. I'll have to
check where this is detected and how. All-in-all, it's not a JSON issue
anyway, but rather an issue with mysqljsonload.

This test in configure fails if libjansson.a doesn't exist in the given
localtion (I always assume a static link here). Also, there is a test
for a function (json_string) to make sure that this is the right
library. Can you do three things for me he (send it to me directly, so
we don't clutter the Jansson mailing list with unnecessary stuff):
1) Try with mysqljsonimport instead of mysqljsonload. This is a much
more recent version (the tool was renamed).
2) Check that libjansson.a exists as /usr/local/lib/libjansson.a
3) Attach the config.log, generated by configure, in the mysqljsonload /
mysqljsonimprt directory to me, and I'll have a look at it.

Cheers
