After two days to struggle with cross compiling(main focus on sbuild),
I have understand the sbuild is how to run. But there are another thing
to confuse me: which one package in FTBFS is right to port Debian?

In another mail thread i pick the libpg-query, then Helmut tell me during
port it will encounter more tricky staff。

OK, the glewmx is right?

https://buildd.debian.org/status/package.php?p=glewmx&suite=sid

http://crossqa.debian.net/src/glewmx

Question : why does not have riscv64 build in crossqa for glewmx?
