These flags are not part of waf, they're custom flags that are not widely implemented. More packages are broken because of these flags being added than actually recognise them. Of the packages in Nixpkgs that directly depend on wafHook that we can attempt to cross compile (i.e. all their dependencies cross compile), 5 already successfully cross compile and recognise these flags, 2 already successfully cross compile because they have been opted out of these flags, 3 don't cross compile successfully for reasons unrelated to these flags, and for the remaining 7, the only thing stopping them cross compiling successfully is that they are being passed these flags that they don't recognise. All of the five successfully cross-compiling packages that do recognise these flags are samba projects: ldb, talloc, tdb, tevent, and samba4. So this isn't a general waf convention, just a samba one. It therefore doesn't make sense to set these flags by default. They should just be included in the expressions for each samba project, like all the other quirks common to samba build systems. This change fixes cross compilation of the following packages: blockhash ganv ndn-cxx mda_lv2 pflask raul saldl

wafHook
Waf is a Python-based software building system.
In Nixpkgs, wafHook
overrides the default configure, build, and install phases.
Variables controlling wafHook
wafHook
Exclusive Variables
The variables below are exclusive of wafHook
.
wafPath
Location of the waf
tool. It defaults to ./waf
, to honor software projects that include it directly inside their source trees.
If wafPath
doesn't exist, then wafHook
will copy the waf
provided from Nixpkgs to it.
wafFlags
Controls the flags passed to waf tool during build and install phases. For settings specific to build or install phases, use wafBuildFlags
or wafInstallFlags
respectively.
dontUseWafConfigure
When set to true, don't use the predefined wafConfigurePhase
.
dontUseWafBuild
When set to true, don't use the predefined wafBuildPhase
.
dontUseWafInstall
When set to true, don't use the predefined wafInstallPhase
.
