building a Codec Engine remote app

Gaston,

Have you set the DEVICES variable in <CE_INSTALL_DIR>/examples/xdcpaths.mak to TI816X?  Also, did you set the various toolchain installation directories in <CE_INSTALL_DIR>/products.mak?

Best regards,

    Janet

Yes I did.

Well, I only set the CC_V5T var and I've noticed by reading the comments that more than one var has to be set. The other one is CGTOOLS_V5T that I have left in blank so how should I set this var?

Gaston,

If you are building a remote app and a server for the DSP, you need to set:

ti.targets.elf.C674

CGTOOLS_V5T

CC_V5T

If you are building a server for the M3, you need to set:

ti.targets.arm.elf.M3

Best regards,

    Janet

Hi Janet,

I'm still not able to build a CE remote application.

CGTOOLS_V5T

CC_V5T

The vars ti.targets.elf.C674 and CC_V5T are set to ${EZSDK}/dsp-devkit/cgt6x_7_3_1 and ${HOME}/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-gcc respectively. Here's the console output when the CGTOOLS_V5T is set to  ${EZSDK}/linux-devkit as your colleague suggested in this post.

I've also read the products.make comment about GCC targets and I wonder what it means with the 'special' distinction.

"# Note that GCC targets are 'special' and require more than one var to be set."

Could you clarify this?

Regards,
gaston 

Janet,

From the last console output I've deduced that CGT var should be set this way:

CGTOOLS_V5T ?= ${HOME}/CodeSourcery/Sourcery_G++_Lite
CC_V5T      ?= bin/arm-none-linux-gnueabi-gcc

Therefore you can override my previous post.

However compilation of CE universal_copy example fails again. Here's the console message and the error output for more details.

Any idea about this issue?

It looks like the universal_copy codec library is not getting linked in.  Did you run 'make' from the top of the examples directory?  Could you verify that the directory

I've run the make from the top of the examples directory and it works well now. Janet, thank so much for your help.

Regarding the building process described in codec_engine_XXX/examples/build_instructions.html

"Each directory contains a GNU makefile which enables you to build the sample in the current directory. Top-level directories also contain a makefile which steps into subdirectories and builds all the examples under the parent directory."

I suggest to add "Before performing the build in a single sample directory It is necessary to build the whole examples from the top of the examples directory" or something like that.

gaston

Gaston,

Thanks for the feedback.  We are re-working the Codec Engine examples so  that each example is self-contained.  That should avoid the problem you encountered.

Best regards,
