Version 0.27 cannot be compiled if pclmuldq is specified

On Linux on Haswell, I got the following error:

% cabal config -f support_pclmuldq

If use_target_attributes is disabled, the build gets fine.

I'm not surprised, I saw this too. GCC 4.8 has a version of the header files requiring global target attributes. GCC 4.9 is fine. How is it serious, are there many distributions still with 4.8? That's precisely why flag use_target_attributes exists.

[kazu-yamamoto]

CentOS 7 provides GCC 4.8 while CentOS 8 uses 8.3. I will try this on CentOS 8. (The reason why I had a CentOS 8 instance is GSO (Generic Segmentation Offload) which is considered as a key to improve the performance of QUIC.)

[kazu-yamamoto]

OK. cabal install cryptonite -f support_pclmuldq works well on CentOS 8. Let's close this.

[ocheron]

Thanks for the details about CentOS. I added a note in the README file.
