Re: [Postgres-xc-developers] [HACKERS] Building on S390

[鈴木 幸市 <ko...@in...>]

Michael;

As you know, XC does not add any changes to configure, except for XC version number and related settings.

If the error is from XC-specific code, they could be improved as well.

Could you let me know how the build failed?   I don’t have S390 build environment.

Regards;
