Azure-iot-sdk-c: hsm_custom_lib > Compile issue

[qzzf1w]

Am on Raspberry PI (Latest version)

Am trying to compile the custom hsm sample.

Running into an issue recognizing libcustom_hsm_example.a

[Command]---------------------------------------------------------

cmake -Duse_prov_client:BOOL=ON -Dhsm_custom_lib="~/azure-iot-sdk-c/cmake/provisioning_client/samples/custom_hsm_example/libcustom_hsm_example.a" .
cmake --build .

Hi @qzzf1w can you try adding this -> -Dhsm_type_custom=ON to your cmake command?

[qzzf1w]

Same issue

sudo cmake -Duse_prov_client:BOOL=ON -Dhsm_type_custom=ON -Dhsm_custom_lib="~/azure-iot-sdk-c/cmake/provisioning_client/samples/custom_hsm_example/libcustom_hsm_example.a" .

sudo cmake --build .

Running from

pi@raspberrypi:~/azure-iot-sdk-c/cmake

[Error]--------------------
make[2]: * No rule to make target '/root/azure-iot-sdk-c/cmake/provisioning_client/samples/custom_hsm_example/libcustom_hsm_example.a', needed by 'iothub_client/samples/iothub_convenience_sample/iothub_convenience_sample'. Stop.

And one more thing.

All of this works on windows

[danewalton]

Okay yea so unfortunately I think the CMake situation could be better here.
TLDR to get you unblocked:

cmake -Duse_prov_client=ON ..
cmake --build .
cmake -Duse_prov_client:BOOL=ON -Dhsm_type_custom=ON -Dhsm_custom_lib="~/azure-iot-sdk-c/cmake/provisioning_client/samples/custom_hsm_example/libcustom_hsm_example.a" .
cmake --build .

Reasoning being the first pass, it will build the custom lib and then the second pass it will link that newly built lib in your solution.

Let me know if that works. I can look to get this to work better on a first pass only but for now that's how it'll work.

EDIT: I ran this on Linux Ubuntu 18.04 and it seemed to work.

[qzzf1w]

I beleive I did two pass but will try again
Stay posted

Here is what I am using (Latest Raspbian build)

Operating System: Raspbian GNU/Linux 10 (buster)
Kernel: Linux 5.4.51+

My precise steps to repro as follows

1. Install new Raspbian image on Micro SD Card
2. Boot
3. sudo apt-get install cmake build-essential
   sudo apt-get install git-core
   sudo apt-get purge -y libssl-dev
   sudo apt-get install libcurl4-openssl-dev
   sudo apt-get install libssl-dev
   sudo apt-get update
   sudo apt-get upgrade
   sudo reboot
4. sudo git clone -b LTS_07_2020_Ref01 --recursive https://github.com/azure/azure-iot-sdk-c.git
   cd azure-iot-sdk-c
   sudo mkdir cmake
   cd cmake
   sudo cmake -Duse_prov_client:BOOL=ON ..
   sudo cmake --build .
   sudo cmake -Duse_prov_client:BOOL=ON -Dhsm_type_custom=ON -Dhsm_custom_lib="~/azure-iot-sdk-c/cmake/provisioning_client/samples/custom_hsm_example/libcustom_hsm_example.a" .
   sudo cmake --build .

Same results

Interesting just tried it on a raspberry pi following your exact steps and it worked. One caveat on your list of commands above. What you have as

sudo cmake -Duse_prov_client:BOOL=ON -Dhsm_type_custom=ON -Dhsm_custom_lib="~/azure-iot-sdk-c/cmake/provisioning_client/samples/custom_hsm_example/libcustom_hsm_example.a" .

It's missing a . at the end. It should be ... But otherwise I ran exactly the same thing and it worked.

[danewalton]

actually maybe try expanding out the relative path of the custom lib?

[qzzf1w]

That is it ~ resolves to "root" I wanted "home/pi"

[danewalton]

Nice! Alright so I'll go ahead and close this for now. Let me know if you want it reopened for any reason.
