gem install dm-postgres-adapter build错误

Question

我正在尝试构建dm-postgres-adapter但是得到了这个错误.

sudo gem install dm-postgres-adapter

Building native extensions.  This could take a while...
ERROR:  Error installing dm-postgres-adapter:
ERROR: Failed to build gem native extension.

安装pg postgresql并设置pg_config路径后安装工作

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

我被绝对困惑的postgres.h是找到了,但不是pg_wchar.h,它位于同一目录中/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,我们走吧!

这对我来说绝对没有意义.

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' ...

"有些事情发生了可怕的错误"

找到pg_wchar.h !!!! 是啊!但等待有一个错误.

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)'
typedef bool (*mbcharacter_incrementer) (unsigned char *mbstr, 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

Answer 1

我修好了这个。

我希望我能给出具体的步骤，但事情是这样的：

• 从苹果开发者网站手动更新命令行工具。

• 卸载所有宝石

• 使用brew安装了rbenv、ruby-build、rbenv-bundler

• 使用brew安装了apple-gcc42

• 使用 rbenv 安装 ruby​​ 2.1

• 设置使用 rbenv 的 ruby​​ 的路径。

• 放rbenv global 2.1.0

• 已卸载的捆绑包

• 已安装的捆绑包

• 跑rbenv rehash

• 跑sudo bundle install成功了。
