Build Error cmake/GCC

[marinuswhite]

Hello,

I'd like to test SPDM on a Nvidia Jetzson Orin (ARM 64, native Ubuntu).

I followed the instruction steps

• Cloned the Repository with Sub-modules

• installed GCC/ARM GNU bare metal as Compiler

• went into the folders

• made the build folder

• tried "cmake -DARCH=(both aarch64/arm) -DTOOLCHAIN=ARM_GNU -DTARGET=Release -DCRYPTO=mbedtls .."
  => "unkown toolchain" , (installed ARM_GNU successfully following the Instructions)

• tried GCC as Toolchain
  => worked

• made the sample key

• then "make"

=>
gcc: error: unrecognized command line option ‘-maccumulate-outgoing-args’
gcc: error: unrecognized command line option ‘-mno-red-zone’
make[2]: *** [out/cryptlib_mbedtls.out/CMakeFiles/cryptlib_mbedtls.dir/build.make:63: out/cryptlib_mbedtls.out/CMakeFiles/cryptlib_mbedtls.dir/cipher/aead_aes_gcm.c.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:922: out/cryptlib_mbedtls.out/CMakeFiles/cryptlib_mbedtls.dir/all] Error 2
make: *** [Makefile:130: all] Error 2

Tried it several times with different settings, always ends there

May I have overseen something?

Thank you!

@twilfredo or @alistair23 might know. I can look at it more when I get access to an Orin system.

[twilfredo]

I haven't come across this before, but those options ( -maccumulate-outgoing-args & mno-red-zone) don't seem to be specified for aarch64?

[marinuswhite]

I tried both arm and aarch64, both ended with the mentioned error

[alistair23]

no-red-zone is only added for x86 and accumulate-outgoing-args is similar (x64 or ia32), so you are building for the wrong architecture.

How did you install ARM_GNU? Are you able to provide the full logs from cmake and make?

@alistair23 (I'm a colleague of @marinuswhite)
I think we didn't specifically install something in addition on the NVIDIA Orin. Since the Orin is an arm64 (or - as far as I understood - alternatively named aarch64) architecture, we assumed the standard toolchain should be the arm one compiling for that target architecture.
I'm not at the device currently, but I can look into providing you with the output later this week.

[steven-bellock]

If this is Linux on native aarch64 then you'd use

cmake -DARCH=aarch64 -DTOOLCHAIN=GCC -DTARGET=Release -DCRYPTO=mbedtls ..

Thanks @steven-bellock, that helped greatly.

This combination unfortunately is not described in build.md.
"Build Tools for Linux" in fact states subitem e) with
AARCH64 GCC for AARCH64 only

sudo apt-get install gcc-aarch64-linux-gnu
but in the subsequent "Linux Builds for ARM/AARCH64" section, there is no mention of
For ARM GCC build (aarch64) on Linux
I may create a pull request for that after we verified the correct workflow.

Regarding the actual build

It seems it almost worked. At the end however, I get the following linker error - full logfile (I used openssl als crypto lib, but I hope this shouldn't matter):

I didn't check yet if the other executables work fine - those apparently compiled & linked without errors.

[steven-bellock]

See #612 for discussion on build parameters and native / cross compilation. Also, https://github.blog/changelog/2023-10-30-accelerate-your-ci-cd-with-arm-based-hosted-runners-in-github-actions/ may come to free GitHub users so we can add that to CI/CD.

I'll file an issue for the test_size_of_ build error. The other tests will run fine.

[dhopf]

I can confirm that I successfully built it on my NVIDIA Jetson AGX Orin Developer Kit.
Inside the created build directory, I issued:

cmake -DARCH=aarch64 -DTOOLCHAIN=GCC -DTARGET=Release -DCRYPTO=openssl ..
make copy_sample_key
make -j12

Thanks @steven-bellock for the swift fixing!

[jyao1]

Is there anything for this issue?
Can we close this one?

[steven-bellock]

The build documentation needs to be clarified, as it is focused on cross-compilation. I can update that.
