[yocto] Problem with TI SDK Build 05.

[David Castelow]

Hi,

I had an issue building the latest TI SDK for Sitara processors (05_00_00_15), and Kemal from TI suggested I post my findings here for comment.

So the build I attempted was for

$ MACHINE=am335x-evm bitbake arago-base-tisdk-image

following instructions from

http //software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Overview.html <http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Overview.html#id13>

and using both Linux Mint 17.3 (trusty based) and Ubuntu Xenial (16.04) as host machines, giving essentially the same error.

The problem appears in failure to build libtool-cross successfully.

I have traced this back to something in the bitbake recipes/patches that modify the libtool configure script:
See http://e2e.ti.com/support/arm/sitara_arm/f/791/p/718479/2660196#2660196 for the history.

The build does succeed if I ensure HOST_SYS is defined:
As I said in my last post to that thread,
Compilation/build is successful if I edit

arago/tisdk/sources/oe-core/meta/classes/nativesdk.bbclass

-#HOST_SYS = "${HOST_ARCH}${TARGET_VENDOR}-${HOST_OS}"
+HOST_SYS = "${HOST_ARCH}${TARGET_VENDOR}-${HOST_OS}"

I think this is because there are libtool related .bb files and .patch files that reference either ${host_alias}-libtool or ${HOST_SYS}-libtool.

If HOST_SYS is empty, then the executable would be called -libtool, and then the configure script fails to clean up as it attempts to execute

rm -libtool

which won't work as the file name starts with a - (were this to work, it would need to do the mv/rm of ./${file} rather than just of ${file}).

I'm not sure if this is the correct solution to the problem, but it suggests the need to set HOST_SYS as part of the build instructions.

Can you advise if this is correct?
