Under 1.9.1 preview 2, I encountered an error with both RString (as above) and RArray. Following instructions regarding RArray here http://www.rubyinside.com/ruby-1-9-1-preview-released-why-its-a-big-deal-1280.html , I modified mysql.c starting on line 1375 as follows:

t.second = FIX2INT(RARRAY_PTR(a)[0]);
t.minute = FIX2INT(RARRAY_PTR(a)[1]);
t.hour = FIX2INT(RARRAY_PTR(a)[2]);
t.day = FIX2INT(RARRAY_PTR(a)[3]);
t.month = FIX2INT(RARRAY_PTR(a)[4]);
t.year = FIX2INT(RARRAY_PTR(a)[5]);

It then compiled and installed correctly.

you can download the official mysql-ruby-1.8.0 that supports ruby 1.9.0.5

What helps me was editing “/usr/include/ruby-1.9.0/ruby/ruby.h” (in your case the file is in “/usr/local/include/ruby-1.9.0″ dir) file and replacing the RString struct with this code:

struct RString {
struct RBasic basic;
union {
union {
struct {
long len;
char *ptr;
union {
long capa;
VALUE shared;
} aux;
} heap;
char ary[RSTRING_EMBED_LEN_MAX];
} as;

struct {
long len;
char *ptr;
union {
long capa;
VALUE shared;
} aux;
};
};
};

I’ve created empty file “version.h” in the “/usr/include/ruby-1.9.0″ dir.

Then I’ve just run “sudo gem1.9 install dbd-mysql” and everything compiled smooth.

Cheers,
Dawid

Awesome, so they fixed mysql binding code to support 1.9.

The latest code from here compiles for me.

Hemant, I get these errors when I try to compile against the 1.9.0 code I just installed:

Any ideas?
