I get linker errors...

This is my toolchain-ark.cmake...

With the following additions...

SET(CMAKE_C_FLAGS_INIT "-L/opt/xiphos/sdk/ark/sysroots/aarch64-xiphos-linux/ -L/opt/xiphos/sdk/ark/sysroots/aarch64-xiphos-linux/usr -L/opt/xiphos/sdk/ark/sysroots/aarch64-xiphos-linux/lib -L/opt/xiphos/sdk/ark/sysroots/aarch64-xiphos-linux/lib64 -L/opt/xiphos/sdk/ark/sysroots/aarch64-xiphos-linux/usr/lib64 -L/opt/xiphos/sdk/ark/sysroots/aarch64-xiphos-linux/usr/lib" CACHE STRING "C Flags required by platform")

Then I get this...

The C compiler

"/opt/xiphos/sdk/ark/sysroots/x86_64-xiphossdk-linux/usr/bin/arm-xiphos-linux/arm-xiphos-linux-gcc"

is not able to compile a simple test program.

It fails with the following output:
