I'm using Visual D and have C:\MyProjects\D\Pegged (the git
clone of pegged) added to the add'l imports field under project
properties > compiler.
I'm getting errors like these:
Error 1 Error 42: Symbol Undefined
_D6pegged7dynamic7grammar7grammarFAyaHAyaDFS6pegged3peg9ParseTreeZS6pegged3peg9ParseTreeZS6pegged7dynamic7grammar14DynamicGrammar (pegged.dynamic.grammar.DynamicGrammar pegged.dynamic.grammar.grammar(immutable(char)[], pegged.peg.ParseTree delegate(pegged.peg.ParseTree)[immutable(char)[]])) C:\MyProjects\D\PeggedPractice\
Error 2 Error 42: Symbol Undefined
_D6pegged7dynamic7grammar12__ModuleInfoZ C:\MyProjects\D\PeggedPractice\
The # of errors was greatly reduced when I added the 3 pegged
source files to my project. What can be going wrong? Thanks!
You need to add most of the pegged files... there are more than
3. Try adding them all first then remove the junk like the
examples, docs, etc until it works.
