[Solved] jSON issue on RTOS SDK V1.4

[ivanroberto]

Hi all,

With new release of RTOS SDK v1.4, i'm getting erros when it links jSON functions.

10:06:44 Build Finished (took 3s.680ms)

Of course, using the old RTOS SDK (v1.3), every thing is fine.

I appreciate if some one help me.

Thanks

Hi,

Please add "-lmirom" in the makefile, and try it again.

If your problem is still unsolved, please feel free to let us know.

Thanks Espressif_Faye,

It works!

[quote="ivanroberto"]Thanks Espressif_Faye,

How can solved it?
But I can solved it for add "-lmirom" to makefile!
why?it display....

Hi,

Please revise your makefile according to the cjson_test/makefile in the attachment.

Hi,
This is my makefile, where to put the "-lmirom" ?
