ruby – gem安装dm-postgres-adapter构建错误

在安装postgresql并设置pg_config路径后安装pg工作

`bundle config build.pg --with-pg-config=/usr/local/Cellar/postgresql/9.3.1/bin/pg_config`

我绝对困惑的是postgres.his发现,但不是pg_wchar.h,它位于同一目录/usr/local/Cellar/postgresql/9.3.1/include

设置配置选项没有帮助

--with-pgsql-server-include=/usr/local/Cellar/postgresql/9.3.1/include

我之前用macports postgresql试过这个.有完全相同的错误后我完全卸载了mac ports并用homebrew安装postgresql.我也试过postgresql包Postgres.app,但我总是得到这个错误.

正如我在安装pg(gem)之前所说的那样.

mkmf.log

如错误消息中所述 – “检查mkmf.log文件以获取更多详细信息.”

>好的,放手吧！

这对我来说绝对毫无意义.

conftest.c:5:57: error: use of undeclared identifier 'main'
int t(void) { void ((*volatile p)()); p = (void ((*)()))main; return 0; }

1 error generated.

checked program was:

/* begin */
1: #include "ruby.h"
2:
3: /*top*/
4: extern int t(void);
5: int t(void) { void ((*volatile p)()); p = (void ((*)()))main; return 0; }
6: int main(int argc,char **argv)
7: {
8:   if (argc > 1000000) {
9:     printf("%p",&t);
10:   }
11:
12:   return 0;
13: }
/* end */

但…

这个

/usr/local/Cellar/postgresql/9.3.1/include/server/mb/pg_wchar.h:363:14: error: function         
cannot return function type 'int (unsigned char *,int)'
typedef bool (*mbcharacter_incrementer) (unsigned char *mbstr,int len);
              ^
/usr/local/Cellar/postgresql/9.3.1/include/server/mb/pg_wchar.h:388:2: error: unknown type     
name 'uint32'

... and lot of "unknown type name 'uint32' ...

“事情发生了可怕的错误”

找到pg_wchar.h !!!!是啊！但等待有错误.

修好了

typedef uint32_t uint32; // added in pg_wchat.h

但接下来是

/usr/local/Cellar/postgresql/9.3.1/include/server/mb/pg_wchar.h:364:14: error: function     
cannot return function type 'int (unsigned char *,int len);

是的,我可以通过尝试修复它,但我不认为这是正确的方法

我完全不知道该往哪里去.所以,如果有人可以提供帮助,我会很感激.

ps：我正在使用mac os mavericks
