无法安装/制作 freetds OS X Yosemite

Question

我正在尝试在我的 Macbook 上安装 gem tiny_tds，所以我首先尝试通过运行 brew install freetds 来安装 freetds 依赖项。但是，它不起作用，我收到一个对我来说毫无意义的错误：

libtool: link: clang -D_THREAD_SAFE -g -O2 -I/usr/local/opt/openssl/include -Wdeclaration-after-statement -o .libs/bsqldb bsqldb.o  -L/usr/local/opt/openssl/lib ../dblib/.libs/libsybdb.dylib ../replacements/.libs/libreplacements.a -lssl -lcrypto /usr/local/Cellar/libiconv/1.13.1/lib/libiconv.dylib

make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1

我也试过从源码编译freetds，也报错：

我真的不明白为什么我不能在我的机器上编译 freetds，如果有人帮助我，我会很高兴的！

提前谢谢你。

Answer 1

我实际上找到了解决问题的方法！显然，Libiconv 是通过 brew 安装为另一个程序的依赖项。但是这个安装不是为我的架构编译的，所以不能正常工作。我不得不卸载 brew 版本的 libiconv 并手动重新安装。

brew uninstall libiconv
brew install libiconv
brew install freetds

我不确定是否有必要通过 brew 重新安装 libiconv，因为它现在应该是 Mac OS 的一部分。希望这对遇到同样问题的人有所帮助。
