I’m trying to create a standalone Windows program to run some Ruby scripts (pretty much as the examples in the Pickaxe book), but I have some troubles when ruby.h is included. I downloaded the free Visual C++ 2008 Express Edition, and building Ruby from sources (Ruby 1.86-p111) was no problem at all and extremely straight-forward with this version. But when creating an application in the IDE, I get some compiling errors when I include ruby.h. It doesn’t matter if I enclose the include in extern “C” or not, same errors. For example: c:\rubysources\ruby-1.8.6-p111\win32\win32.h(172) : error C2061: syntax error : identifier ‘fd\_set’ c:\rubysources\ruby-1.8.6-p111\win32\win32.h(188) : error C2146: syntax error : missing ‘;’ before identifier ‘rb\_w32\_get\_osfhandle’ c:\rubysources\ruby-1.8.6-p111\win32\win32.h(188) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int Since I can build from sources with nmake, it must be a matter of configuration, right? Ideas anyone? Best regards, Jari W.
