I am new to Buildroot and working on using Buildroot to use Linaro as a kernel and build UEFI.

For building UEFI it needs ACPI tools mainly iasl command.. But iasl command available as a part of buildroot cant be executed and gives following error:

"Cant Execute iasl command"

I checked the file type of iasl and found out it is x86 while My system on which buildroot is running is x86_64. Not sure if this is the reasom for iasl to be failing..if so how can we specify buildroot to generate x86_64 tools?

error from buildroot logs is:

You're not giving enough details, but my feeling is that you might have built iasl for the target, and try to run it on the machine where you're running the Buildroot build. Cannot work. Make sure to use the host-acpica package.
