Haxe: rebuild hxcpp failed with Error: Could not find build target "std"

Question

Trying to rebuild hxcpp failed with the cryptic error message:

Error: Could not find build target "std"

Answer 1

Some users report this hint (I swear I didn't see it when I hit the issue, unless I'm just blind):

Have you tried rebuilding the hxcpp.n and build.n scripts?
This is done by running haxe in the tools/hxcpp and tools/build directories.

Hence:

cd hxcpp/tools/hxcpp
haxe compile.hxml
cd ../build
haxe compile.hxml

Fixes it.

Also note that nightly hxcpp builds are available from nmehost.com and openfl.org if you just need a newer version than what's available via haxelib.
