安装 pg 安装postgresql并设置后pg_config path

 `bundle config build.pg --with-pg-config = / usr / local / Cellar / postgresql / 9.3 .1 / bin / pg_config` 
  

我非常困惑的是找到postgres.h ，但不是pg_wchar.h，它位于同一目录 /usr/local/Cellar/postgresql/9.3.1/include

设置配置选项不会帮助

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

我以前曾用macports postgresql试过这个。在发生同样的错误之后，我完全卸载了mac端口并用自制软件安装了postgresql。我也试过postgresql包 Postgres.app 但我总是得到这个错误。

正如我在安装前所说pg（gem）有效。

mkmf.log h2>

如错误信息中所述 - 检查mkmf.log文件以获取更多详细信息。

• 确定，放手！

这对我来说绝对没有意义。

  conftest.c：5：57：错误：使用未声明的标识符'main'
 int t（void）{void（（* volatile p）（）） ; p =（void（（*）（）））main;返回0; } 
 
 1生成的错误。 
 
检查程序是：
 
 / * begin * / 
 1：#includeruby.h
 2：
 3： / * top * / 
 4：extern int t（void）; 
 5：int t（void）{void（（* volatile p）（））; p =（void（（*）（）））main;返回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...

这一个

  /usr/local/Cellar/postgresql/9.3 .1 / include / server / mb / pg_wchar.h：363：14：error：function 
无法返回函数类型'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：错误：未知类型
名称'uint32'
 
 ...和很多未知类型名称uint32'... 
  

---

发生了可怕的错误

pg_wchar.h被发现!!!!是啊！但是等一下有错误。

使用

  typedef uint32_t uint32; //添加在pg_wchat.h中
  

但是接下来是

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

是的，我可以通过并试图解决它，但我不认为这是正确的方式。

我绝对不知道该往哪里走，所以如果有的话dy可以帮助我感激它。

ps：我正在使用mac os mavericks

解决方案我修正了这个问题。

我希望我可以给出确切的步骤，但它是这样的：

• 手动更新来自Apple开发者网站的命令行工具。




• 卸载所有宝石




• 使用brew安装rbenv，ruby-build，rbenv-bundler使用brew安装apple-gcc42使用rbenv安装ruby 2.1

使用rbenv的ruby设置路径 / b>


• 设置 rbenv global 2.1.0




• 已卸载的软件包




• 已安装的软件包




• > rbenv rehash




• Ran sudo bundle install 已成功。

i'm trying to build dm-postgres-adapter but get this error.

sudo gem install dm-postgres-adapter

Building native extensions.  This could take a while...

installing pg worked after installing postgresql and setting pg_config path

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

what i am absolutly confused about is that postgres.his found, but not pg_wchar.h which is in the same directory /usr/local/Cellar/postgresql/9.3.1/include

setting configuration options doesnt help

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

i've tried this with macports postgresql before. after having the same error i've completly uninstalled mac ports and install postgresql with homebrew. I also tried the postgresql package Postgres.app but i get always the this error.

as i said before installing pg (gem) worked.

mkmf.log

as said in error message - "Check the mkmf.log file for more details."

• ok, lets go!

this makes absolutely no sense to me.

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 */

but...

this one

/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' ...

---

"Something went horribly wrong"

pg_wchar.h is found!!!! yeah! but wait there is an error.

fixed it with

typedef uint32_t uint32; // added in pg_wchat.h

but then comes the next

/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)'
typedef bool (*mbcharacter_incrementer) (unsigned char *mbstr, int len);

yes, i could go this through and trying to fix it, but i don't think that this is the right way

i have absolutely no idea where to go on. So if somebody could help i would appreciate it.

ps: i am using mac os mavericks

解决方案

I fixed this.

I wish I could give exact steps, but it was something like this:

• Manually updated Command Line Tools from the apple developer site.

• Uninstalled all gems

• Installed rbenv, ruby-build, rbenv-bundler using brew

• Installed apple-gcc42 using brew

• Installed ruby 2.1 using rbenv

• Set path to use rbenv's ruby.

• Set rbenv global 2.1.0

• Uninstalled bundle

• Installed bundle

• ran rbenv rehash

• Ran sudo bundle install successfully.
