Failed to start on AIX
What did I miss?
The news post about the release:
you should only attempt to build the source code on GNU/Linux from here on. Should you need to use NXLog on some other operating systems we'd encourage you to try the NXLog Enterprise Edition as it comes with pre-built binary packages for IBM AIX, FreeBSD, OpenBSD, Apple macOS and Oracle Solaris and it also supports a lot more data sources as it can read audit logs natively, supports file integrity monitoring and has dozens of other extra features.
