PROCESSOR-SDK-OMAPL138: Issues in cross compiling

Part Number: PROCESSOR-SDK-OMAPL138
Other Parts Discussed in Thread: OMAPL138

Hi,

I am using OMAPL138 SDK v6.03. While compiling a simply C Hello world program, it shows an error saying that "stdio.h: no file found". I set the PATH as export PATH=”<SDK INSTALL DIR>/linux-devkit/sysroots/x86_64-arago-linux/usr/bin:$PATH same as specified in the guide https://software-dl.ti.com/processor-sdk-linux/esd/docs/06_03_00_106/linux/Overview/GCC_ToolChain.html. I don't know what I am missing.

Hi Rejin,

Please see the file Rules.make in the SDK installation directory:

export CROSS_COMPILE=$(LINUX_DEVKIT_PATH)/sysroots/x86_64-arago-linux/usr/bin/arm-oe-linux-gnueabi/arm-oe-linux-gnueabi-
export CC=$(CROSS_COMPILE)gcc --sysroot=$(SDK_PATH_TARGET)

So please ensure you setup the cross compile toolchain correctly, especially to use '--sysroot' in the compile command.

Hi Rejin,

what Bin suggested should work but why not simple use ("source") the environment-setup script from the linux-devkit folder? And then you can compile using $CC and $CXX and $LD and such and it all should just work including headers and libraries etc.

Regards, Andreas

Hi Bin,

While doing the above export command I got an error as "bash: export: `--sysroot=$(SDK_PATH)/linux-devkit/sysroots/armv5e-oe-linux-gnueabi/': not a valid identifier".

Hi Andreas,

I have no idea how to use $CC, $CXX and $LD command. I am completely new with all this commands. Any guide to use this.

Please instead do what Andreas recommended, it will resolve this error.

cd linux-devkit/
source environment-setup
