Unable to build the iceoryx2 c++ bindings for ARM architecture VxWorks

[LoreleysMelody]

Required information

Operating system:

• Cross compiled in Linux Mint for VxWorks 7 for the following board: https://www.ti.com/tool/TMDX654IDKEVM#description (aarch64-wrs-vxwork or armv7-wrs-vxworks-eabihf) adapting the following instructions: https://github.com/ekxide/iceoryx2/blob/vxworks-mvp/doc/development-setup/vxworks.md

Rust version:
Output of: rustc --version: 1.82.0

Cargo version:
Output of: cargo --version: 1.82.0

iceoryx2 version:
https://github.com/ekxide/iceoryx2/tree/vxworks-mvp

Detailed log output:
target/ffi/build/generated/iceoryx_platform/include/iceoryx_platform/platform_settings.hpp:20:10: fatal error: 'linux/limits.h' file not found
#include <linux/limits.h>
1 error generated.

Observed result or behaviour:
Can not compile iceoryx2 c++ bindings

Expected result or behaviour:
The iceoryx2 c++ bindings can be compiled

Conditions where it occurred / Performed steps:
Create VSB and a VIP for the board. Create a custom sdkenv.sh.
Within the Wind River Workbench Development Terminal call the following commands:

• source sdkenv.sh
• cargo build --package iceoryx2
• mkdir iceHoof
• cd iceHoof
• git clone --depth 1 --branch v2.95.5 https://github.com/eclipse-iceoryx/iceoryx.git target/iceoryx/src
• cmake -S target/iceoryx/src/iceoryx_platform -B target/iceoryx/build/platform -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=target/install -DIOX_PLATFORM_MINIMAL_POSIX=ON -DCMAKE_SYSTEM_NAME=VxWorks
• cmake --build target/iceoryx/build/platform
• cmake --install target/iceoryx/build/platform
• cmake -S target/iceoryx/src/iceoryx_hoofs -B target/iceoryx/build/hoofs -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=target/install -DCMAKE_PREFIX_PATH="$(pwd)/target/install" -DIOX_USE_HOOFS_SUBSET_ONLY=ON -DCMAKE_SYSTEM_NAME=VxWorks
• cmake --build target/iceoryx/build/hoofs
• cmake --install target/iceoryx/build/hoofs
• cd ..
• cargo build --release --package iceoryx2-ffi
• cmake -S . -B target/ffi/build -DCMAKE_INSTALL_PREFIX=target/install -DCMAKE_PREFIX_PATH="$(pwd)/iceHoof/target/install" -DRUST_BUILD_ARTIFACT_PATH="$(pwd)/target/aarch64-wrs-vxworks/release"
• cmake --build target/ffi/build

Can you also try DCMAKE_SYSTEM_NAME=VxWorks when building the C++ bindings?

Quite busy today. Not sure if I have time to dig deeper into the issue.

[LoreleysMelody]

Sadly didn't help.
adapted procedure:

• ...
• cd ..
• cargo build --release --package iceoryx2-ffi
  cmake -S . -B target/ffi/build -DCMAKE_INSTALL_PREFIX=target/install -DCMAKE_SYSTEM_NAME=VxWorks -DCMAKE_PREFIX_PATH="$(pwd)/iceHoof/target/install" -DRUST_BUILD_ARTIFACT_PATH="$(pwd)/target/aarch64-wrs-vxworks/release"
• cmake --build target/ffi/build

This still leads to the same error

[elBoberido]

Please check the installed iceoryx_platform. It looks like the linux platform was build instead of the minimal_posix one.

The error message results from iceoryx_platform/linux/cmake/platform_settings.hpp.in but iceoryx_platform/minimal_posix/cmake/platform_settings.hpp.in should be used

Hi,

I created a script to get reproducible errors.
buildIceoryx2.sh

The original error of this ticket is gone, but I now get the following error in the very last step of the process:

cmake --build target/ffi/out-of-tree

This needs a little bit more investigation and I'm currently out of office.
