Sorry, this could be a bug report and not a question, and probably the wrong place to post it then.
I installed gdc according to the instructions given in http://www.dsource.org/projects/tango/wiki/MacOSXInstall from http://sourceforge.net/project/downloading.php?group_id=135857&filename=gdc-trunk-r229- mac-10.5.dmg&a=83983351 Install went well, compiling tango went well. Compiling programs with tango works well. However, now when I try to compile the simplest program that uses std.stdio I get many errors, starting with: ldblcompat.d:36: Error: identifier 'string' is not defined (below it, many complaints about string not defined, and also include/d/4.0.1/std/format.d:75: Error: Error is used as a type ) My program is this: import std.stdio ; int main() { writefln("Hello world!\n") ; } What am I doing wrong?
