Hi,
I am a new TI Sitara user for an embedded project. I have installed Sitara Linux SDK, which has the Linaro Toolchain. I want to use NE10 simply for DSP algorithm. Thus, it needs to set variable
GNULINUX_PLATFORM? (But I do not know how to set it)
It is not directly for Android. Excuse me for this non-Android question because I cannot find other appropriate forum for that.
After export the path:
SDK_INSTALL_DIR=$HOME/ti-sdk-am335x-evm-06.00.00.00
export PATH="$SDK_INSTALL_DIR/linux-devkit/sysroots/i686-arago-linux/usr/bin:$PATH"
the toolchain is verified that I can run it by:
But I still cannot build the NE10 library, please see the below message. I am new to GCC environment. Could you give me more detail information on Cmake or something other modification needed?
Regards,

I am still trying to compile NE10 library. First of all, I think Ubuntu/Linaro gcc 4.7.3 toolchain works in Ubuntu 12.04 LTS. Now, I want to use Android Emulator to simplify problems without considering any TI tool here. I want to generate NE10 library for the general Android use in the post.
When I run
arm-linux-gnueabi-gcc
it looks for input file. I think the Linaro Toolchain works now. cMake also works after installed it.
CMakeBuilding.txt under folder Home/projectNe10-Ne10-4167142/doc says that
make
I do not know what I should modify in GNUlinux_config.cmake to generate the library. (Or, I can use GNUlinux_config.cmake directly?)
When I run the above commands, it says:
robert@robert-M5100:~/projectNe10-Ne10-4167142/build$ cmake -DCMAKE_TOOLCHAIN_FILE=../GNUlinux_config.cmake ..-- Configuring done-- Generating doneCMake Warning: Manually-specified variables were not used by the project:
Is the above right considering the warning? What causes the warning?
When I continue to run "make", it has errors:
What is wrong in the library building? Could you help me?
I notice that in link:Ne10 Library Getting Started says
$cmake -DCMAKE_TOOLCHAIN_FILE=../config.cmake ..
but I cannot see config.cmake file there.
There is a file under folder Home/projectNe10-Ne10-4167142/ named GNUlinux_config.cmake. But, I do not know what I should/must to modify to use Ubuntu Linaro toolchain.
Thanks,
