Hi Robert,

Thanks for the gist: https://gist.github.com/RobertCNelson/aca2d52e962c80343857

Our latest problem is that we can't successfully cross-compile the ti-opencl-monitor package under Buildroot.

>> Compilation failure
Makefile.am57x:147: recipe for target 'objs/edma.obj' failed
make[2]: *** [objs/edma.obj] Error 1

1 catastrophic error detected in the compilation of "src/monitor.c".
Compilation terminated.

I saw the list of dependencies for ti-opencl-monitor in your gist and we are utilizing a similar list.

config BR2_PACKAGE_TI_OPENCL_MONITOR
	bool "ti-opencl-monitor"
	depends on BR2_arm
	select BR2_PACKAGE_HOST_TI_CGT_C6X
	select BR2_PACKAGE_HOST_TI_FRAMEWORK_COMPONENTS

	select BR2_PACKAGE_HOST_TI_SYSBIOS
	select BR2_PACKAGE_HOST_TI_XDCTOOLS
	select BR2_PACKAGE_TI_EDMA3_LLD
	select BR2_PACKAGE_HOST_TI_AETLIB
	select BR2_PACKAGE_HOST_TI_XDAIS
	select BR2_PACKAGE_TI_IPC

We should be building the `host-ti-xdais` package but I can't find that missing xdas.h header anywhere on my system.

I know you were able to build ti-opencl-monitor successfully using your Debian-based build system.  I am looking at your Debian build scripts for some answers.

https://github.com/beagleboard/repos/tree/master/ti-opencl/suite/jessie/debian

But all I came up with was this.

# Currently the monitor must be built in an X86 cross-compile environment
# If doing an opencl build/install on an ARM platform the monitor files
# must be copied over.
override_dh_auto_build:
  mkdir -p ./monitor/monitor_am57x/
  cp -v /usr/share/ti/opencl/dsp.out ./monitor/monitor_am57x/dsp0.out
  cp -v /usr/share/ti/opencl/dsp.syms ./monitor/monitor_am57x/dsp0.syms
  cp -v /usr/share/ti/opencl/dsp_syms.obj ./monitor/monitor_am57x/dsp0.syms.obj
  cp -v /lib/firmware/dra7-dsp2-fw.xe66 ./monitor/monitor_am57x/dsp1.out
  dh_auto_build -- BUILD_OUTPUT=lib BUILD_AM57=1 ARM_LLVM_DIR=/opt/ti-llvm-3.6 DESTDIR=$(CURDIR)/debian/ti-opencl

I'm not sure what dh_auto_build does.  This is all we're doing Buildroot to try to build that `ti-opencl-monitor` package.

define TI_OPENCL_MONITOR_BUILD_CMDS
  $(TARGET_MAKE_ENV) $(MAKE) -C $(@D)/monitor $(TI_OPENCL_MONITOR_MAKE_OPTS)
endef

Thank you for your assistance.

Hi Frank,

Yeap, opencl-monitor is one i couldn't build purely on debian...
Oh, "jessie" is locked in a old release, use the stretch varient..

These 4 files are taken from the ti opencl-monitor package:

I have them hosted here for easy access:

Looks like this is from:

Nothing special in meta-ti's xdais package: http://git.yoctoproject.org/cgit/cgit.cgi/meta-ti/tree/recipes-ti/xdais

Hi Robert,

I downloaded and copied that xdais stuff that was missing to output/build/ti-opencl-monitor-v01.01.18.00/monitor/src/ti/xdais

Now I am getting the following compilation error when i try to build ti-opencl-monitor.

"src/monitor.c", line 92: fatal error: cannot open source file "GDB_server.h"

1 catastrophic error detected in the compilation of "src/monitor.c".

Compilation terminated.

>> Compilation failure

I didn't know gdbserver was a dependency of ti-opencl-monitor.  Maybe it's needed for dsptop.

and we don't built the device tree node for dsptop/debugss anymore
either, yet that include is still needed..
