ARM64 cross compiled tbb lib link errors

Jump to solution

Hello,

I would like to use the TBB on my dev board (linux, ARM Cortex-A53 MPCore) and I am running into issue with linking the cross compiled TBB for ARM64 with my application. A simple Hello World cross compiled with same compiler runs on the target linux OS minus tbb. If buid for host platform with tbb compiled for Host x86 it works fine.

My introduction to TDD was from this article: https://solarianprogrammer.com/2019/05/09/cpp-17-stl-parallel-algorithms-gcc-intel-tbb-linux-macos/

I just followed it and then for cross compiled switched to cross compiler to create the tbb libs for arm64. I have been able to use TBB on my raspberry PI4 successfully with latest gcc and tbb source but built on PI. 

Not sure if there is a flag I am missing or something simple. Checked all the paths and those point to correct libs based on the link above.

Dev Setup:

Ubuntu 16.04 VM using C++17 and utilizing std execution policy feature.

I have cross compiled TBB 2019_U9 with aarch64-linux-gnu-g++-9.

I just have a simple program that sorts for now just to test the std::execution policy.

example: std::sort(std::execution::par, curr_data.begin(), curr_data.end());

Any suggestions would be great, Thanks!

Hello, there is something

Jump to solution

Hello, there is something wrong with your build scripts. there are lin64-tbb-export.def def files so the library build should fails in case it can't export symbols from that def file. I've tried ubuntu's default 7.4 cross compiler, everything look ok there except I can launch nothing:)

Hi,

    This is a question that requires understanding of the TBB build process. I asked TBB developers to help through the internal email. You might also contact them directly:

1) Publicly on the forum: https://software.intel.com/en-us/forums/intel-threading-building-blocks 

2) Directly to the team; In the linked documentation we have included the contact email Inteltbbdevelopers@intel.com

Hi Brian,

Hi Brian,

It seems that either correct TBB library is not in the path during the linking process or the built TBB library does not have necessary symbols exported.

Could you please check what exactly TBB library the linker uses and does this library have necessary symbols?

Regards, Aleksei

Aleksei,

Aleksei,

TBB is in the path and I did not have any other tbb installed previously. As previously stated building the lib for x86 works fine and linking to my simple program works ok.

Here are the consolidated undefined refs:

 undefined reference to `tbb::internal::allocate_additional_child_of_proxy::allocate(unsigned long) const'
 undefined reference to `tbb::interface7::internal::isolate_within_arena(tbb::interface7::internal::delegate_base&, long)'
 undefined reference to `tbb::internal::allocate_child_proxy::allocate(unsigned long) const'
 undefined reference to `tbb::internal::allocate_continuation_proxy::allocate(unsigned long) const'
 undefined reference to `tbb::internal::allocate_via_handler_v3(unsigned long)' 
 undefined reference to `tbb::internal::allocate_root_proxy::allocate(unsigned long)'

Attached are symbol dump (nm -gDC libtbb.so.2) of the libtbb.

 

Context Example: 

Following line compiles with arm64 tbb using std::execution::seq

  • std::sort(std::execution::seq, curr_data.begin(), curr_data.end());

but when I use the built in parallel then I get the undefined refs

  • std::sort(std::execution::par, curr_data.begin(), curr_data.end());

 

Not sure if there is a flag that is not getting set during the build process, feels like its something simple that I am missing.

Thanks

Hello, there is something

Jump to solution

Hello, there is something wrong with your build scripts. there are lin64-tbb-export.def def files so the library build should fails in case it can't export symbols from that def file. I've tried ubuntu's default 7.4 cross compiler, everything look ok there except I can launch nothing:)

Vladimir,

Vladimir,

Thanks for the hint! Build script linux.inc needed to be updated for correct arch and 64 bit def file. Linking now and running on target.

Thanks,

Brian Evans
