Not quite. You shouldn't do xdc.useModule('ti.sdo.ce.image1.IIMGENC1') because
IIMGENC1 is an Interface, not a Module. Kind of the right idea - we need to
get that ti.sdo.ce.image1 support package brought into the executable.
What really should happen is that ti.sdo.codecs.jpegenc.dm355.ce.JPEGENC Module
should declare (in it's JPEGENC.xdc Module spec file) that it implements the
ti.sdo.ce.image1.IIMGENC1 interface. That will cause the support for that
interface (namely the library with those IMGENC1_* APIs) to be added to the
generated linker.cmd file when the config step sees a codec that needs that
support has been integrated.
When you run your config step, does the generated linker.cmd file include a
library from the ti/sdo/ce/image1 package? Maybe you either 1) forgot to run
the config step after changing your .cfg script or 2) aren't passing the newly
generated linker.cmd into your linker?

Subject: RE: undefined reference to 'IMGENC1_create' error
Either the application .cfg file or some included package would need to do:
xdc.useModule('ti.sdo.ce.image1.IIMGENC1');
to bring in the library containing IMGENC1_create().
I'm not familiar with the details of the ti.sdo.codecs.jpegenc.dm355.ce.JPEGENC
module so I can't check that out, but perhaps you need to manually invoke the
above statement in your cfg.

Subject: undefined reference to 'IMGENC1_create' error
Hi,
I am getting an error of undefined reference to 'IMGENC1_create' I have added
the appropriate header file #include ti/sdo/ce/image1/imgenc1.h to the code,
I suspect that something in the cfg file may be not correct to make it not link
to the proper libraries?
This is my cfg file I am using! Thank in advance
