I was the one who presented Jurko with this issue. Thanks for the
explanation. To avoid messing with boost build sources I added the
following to Other/mygen.jam, right before the generator registration:
local generators = [ modules.peek generators : .generators ] ;
for local gen in $(generators)
modules.poke generators : .vstg.$(gen) ;
local generator-source-types = [ $(gen).source-types ] ;
for type in $(generator-source-types)
modules.poke generators : .vst.$(type) ;
With this the project compiles correctly. I have probably deleted more
cache than necessary. Someone with more boost build insight might
convert this into an actual patch.
