Hi Ze,

I haven't heard of anyone porting Cap'n Proto to QNX, but it should be
possible.

`sigaltstack()` is only used as part of `printStackTraceOnCrash()`, which
is a totally optional helper that is very OS-specific. You could start by
adding some #if/#else such that this function is empty on QNX. There's
probably a number of other places around the library where you'll need to
do similar things, but not too many, as long as you're sticking to just
libkj and libcapnp. libkj-async will probably be a lot more complicated to
support, but it's only needed for RPC -- if you only care about
serialization then you can ignore that part.

[capnproto] Build error on QNX

[Ze Liu]

Hi everyone，

Recently I'm working on building capnp libraries on QNX. And I faced an 
issue that kj library source code has the same header files with QNX, like 
‘exception.h’. And also the kj library needs some interfaces that QNX 
doesn't provide, like signaltstack. For this interface, the QNX header file 
says not supported for now.

I wonder is there a special version adapted with QNX? Or has anyone tried 
to use capnp on QNX?

Many thanks!
