Hi,

I tried to compile latest worker 3.15.3 on Mageia Cauldron but it fails to build on aarch64 dur to:

Hi,

as a quick workaround you can add the compile flag "-fsigned-char" to make it compile again. The problem is within code generated by ragel. On your architecture char is unsigned and a ragel structure uses a char array containing -1 thus leading to this error. I will look for a permanent solution for the next release which does not require this flag.

Thanks for the report.

Ralf
