We still need to keep the operator _intern because there is no easy way to translate it into a macro. Added a pragma message to notify the user of the problem and let them know user string interning is not currently possible on GCC. Relates to #79. Change-Id: Ia1c51d59f7df41cf9e1e98d3ed4834e53128da5a

It seems
GCCignores section attributes for static members of a template class. This causes the interned strings to be stored in.rodatainstead of the custom interned sections.interned_strings. This is currently supported byclang(at least from version 10), butGCCsilently ignores the section attribute and does not even provide a warning message.https://stackoverflow.com/questions/36279162/section-attribute-of-a-function-template-is-silently-ignored-in-gcc
