Hi Ranjit,

I am trying to compile llvmlite package on AIX 7.2: I untar'ed it to a folder and run the following to install. I got following error (unsupported platform: 'aix'). Can you please help?
export CC="gcc -maix64 -pthread"
export CXX="g++ -maix64 -pthread"
export OBJECT_MODE=64
run 'python3 -m pip install . --root / -v'

Thanks

Mi

Hi Wang,

The above error (unsupported platform: 'aix') can be fixed using below change.
But I guess , you will encounter next issue mentioned in previous discussion https://community.ibm.com/community/user/power/discussion/install-of-shade-package-llvmlite-package-llvmlite-package-aix-platfrom-error

Hi Ranjit,

I have following questions:

1. If we install "clang+llvm-16.0.4-powerpc64-ibm-aix-7.2.tar" from LLVM official site, will it create the llvm-config file?
2. We have install llvm-installer and it created following under /opt/freeware/lib/python3.9/site-package. Will this help the installation of llvmlite?

Hi Wang,

I am looking into it and trying to build llvmlite.

I will provide further update once I get more clarity . 

Thanks

Ranjit

Hi Ranjit,

Package "clang+llvm-16.0.4-powerpc64-ibm-aix-7.2.tar" on LLVM official is specifically created for AIX 7.2 running on 64 bits PowerPC structure and should have all LVM modules like lvmconfig.exe. I am wondering if you can make use of that package to speed up the adoption of llvmlite to AIX?

Thanks

Mi

HI Wang,

As mentioned in https://github.com/numba/llvmlite , llvmlilte is having compatibility dependency with llvm 14.
I had tried to compile llvm14 in AIX but I got stuck and got to know that llvm14 is required some more code change to support XCOFF object files.
Right. now, me and team is busy with other activities., So this activity is in our bucket list , but not in high priority.
