C++ 正在重新编译libiconv，gettext未定义符号发生在已成功安装之后

主要明显错误“

架构x86\u 64的未定义符号”

如何使这些文件再次成功编译

操作系统为Mac OS X。已从安装了多个程序
他们的来源。安装后注意到问题：


binutils
v2.25
libtool
v2.4.6
glib
v2.45.2，或
pkgconfig
v0.28

在安装上述任何一项之前，请重新编译
libiconv
和
gettext
未产生任何错误，两个都已成功安装多次

pkg config--list all
不显示
libiconv
或
gettext
（如果这意味着任何重要的事情）

libiconv
和
gettext
是各自网站的直接副本


如果我没有为
gcc
指定
-m32
，则我收到以下错误：

$ gcc -I/usr/local/include -liconv -o test-iconv.exe test-iconv.c
Undefined symbols for architecture x86_64:

可能是您安装了gcc和ar的替代版本，并且它们位于标准位置（/usr/bin）之前的路径中

---

我过去也遇到过同样的问题，这篇文章帮助我解决了问题：

--libiconv前缀=/usr/local/include

看起来可疑。

iconv.h

安装在

/usr/local/include

。我还有

-I/usr/local/include

用于

gcc

以便

.c

文件可以访问它。对于所有的程序，我都没有更改它们的

--前缀=

来自

/configure--help

关于

libiconv

：

--带有libiconv前缀[=DIR]在DIR/include和DIR/lib中搜索libiconv

这就是我要的。将AR和RANLIB设置为/usr/bin中的版本就成功了。
