重新编译libiconv,gettext未定义的符号发生在已成功安装后

pkg-config libtool shared-libraries macos c++

Å½aMan · 技术社区 · 9 年前

主要明显错误“ Undefined symbols for architecture x86_64 "

如何再次成功编译?

操作系统为Mac OS X 他们的来源。安装后注意到问题:

binutils 第25版 ,
libtool 第4.6版 ,
glib v2.45.2版本 ,或
pkgconfig 0.28版

在安装上述任何组件之前,请重新编译 libiconv 和 gettext 没有产生任何错误,并且都成功安装了多次。

pkg-config --list-all 不显示 它本身 也没有 吸气管 (如果这意味着任何重要的事情)

它本身 和 吸气管 是他们各自网站的直接副本。

`它本身` 2014版

正在尝试使用 它本身 在一个简单的 .c 文件:

#include <iconv.h>
// works: gcc -m32 -I/usr/local/include -liconv -o test-iconv.exe test-iconv.c
// does NOT work: gcc -I/usr/local/include -liconv -o test-iconv.exe test-iconv.c
int main(int argc, char **argv) {
    iconv_t conv = iconv_open("ISO8859-1", "UTF-8");
    if (conv != (iconv_t) -1) {
    return 0;
    }
    return 1;
}

如果我没有指定 -m32 对于 gcc 然后我收到以下错误:

$ gcc -I/usr/local/include -liconv -o test-iconv.exe test-iconv.c

可能是安装了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,这篇文章帮助我排除了故障并修复了: https://www.unix.com/programming/253809-linker-errors-linking-files-os-x.html
