Similar to C counterparts, use OPTEE_CLIENT_EXPORT as a standard path to export pre-built optee-client libraries and headers. Signed-off-by: Sumit Garg <sumit.garg@linaro.org>
Similar to C counterparts, use TA_DEV_KIT_DIR as a standard path to export pre-built TA libraries and headers. Signed-off-by: Sumit Garg <sumit.garg@linaro.org>
Refactor OP-TEE rust examples build infrastructure to rather use standard environment variables like: - CROSS_COMPILE - TA_DEV_KIT_DIR With that remove any custom OPTEE_* environment variables. Signed-off-by: Sumit Garg <sumit.garg@linaro.org>
Rather than automatically building OP-TEE OS and OP-TEE Client, we
should ask users to build them for their particular platforms using
whichever OP-TEE release they are targeting.
Users just have to export paths for OP-TEE OS build artifacts via
TA_DEV_KIT_DIR and for OP-TEE Client via OPTEE_CLIENT_EXPORT. This is
the common practice followed by C counterparts like optee_test and
optee_examples. Along with that it make OP-TEE rust examples compatible
with build systems like Yocto etc.
Regarding toolchains, we don't need to fetch them explicitly but rather
users can use the distro cross compiler or the one they have installed
on a particular location via CROSS_COMPILE environment variable.
With that build command simplifies to just following:
$ make CROSS_COMPILE=aarch64-linux-gnu- \
TA_DEV_KIT_DIR=<optee_os>/out/arm-plat-vexpress/export-ta_arm64/ \
OPTEE_CLIENT_EXPORT=<optee_client>/out/export/

Since we don't have a similar linker script pre-processing capability in rust build script as we have with C Makefile. So manually fix following build error seen with older GCC linker while parsing linker scripts: aarch64-linux-gnu-ld.bfd:ta.lds:3: ignoring invalid character `#' in expression Signed-off-by: Sumit Garg <sumit.garg@linaro.org>
arm-none-linux-gnueabihf-ld.bfd reports EABI version mismatch issue, drop that error via adding "--no-warn-mismatch" linker flag. Signed-off-by: Sumit Garg <sumit.garg@linaro.org>
Extend CI to build OP-TEE rust examples for both Arm 64-bit and Arm 32-bit mode. Signed-off-by: Sumit Garg <sumit.garg@linaro.org>

@DemesneGH The CI has been updated now for refactored build infrastructure. Also, I have added standalone rust examples build too for both Arm 64-bit as well as Arm 32-bit. Please trigger CI again. Although, there is still one dependency as OP-TEE/build#715 left for CI to completely pass. |
Since this is merged, can you re-trigger the CI build now? I hope it should pass now. |

merged, thanks! |
