Run-time error on the docker container built with s390x/ubuntu

[harrypgh12]

Hi,

I have built cFS v6.8 on my host computer with ubuntu18.04 and was able to run it communicating with Cosmos.

Also I was able to build a docker container for cFS v6.8 with s390x/ubuntu (IBM zSeries Based Linux, big endian CPU), but I have an error when I build cFS in the docker container and run it.

root@hkim:~/cfs/build/exe/cpu1# ./core-cpu1
CFE_PSP: Default Reset SubType = 1
CFE_PSP: Default CPU ID = 1
CFE_PSP: Default Spacecraft ID = 43
CFE_PSP: Default CPU Name: cpu1
OS_Posix_TableMutex_Init():220:Error: pthread_mutex_init failed: Operation not supported
OS_API_Init():116:OS_API_Impl_Init(0x1) failed to initialize: -1
OS_API_Init():195:Warning: Microsecs per sec value of 0 does not equal 1000000 (MicroSecPerTick: 0 TicksPerSecond: 0)
CFE_PSP: OS_API_Init() failure
Aborted (core dumped)

The error occurs in osal/src/os/posix/src/os-impl-common.c.
OSAL: Development Build: 5.0.0+dev247

But if I build the docker container by changing to i686/ubuntu or i386/ubuntu (little endian CPU) in the same Dockerfile, I have no run-time errors and can run cFS with problems. I wonder if anyone had the same problem with s390x and found a way to fix this error.

If you know another big endian CPU that I can build a docker container with, please let me know.

Thank you!
