c++ - 重新编译libiconv，在成功安装后出现gettext undefined symbol

主要的明显错误“Undefined symbols for architecture x86_64”



操作系统是Mac OSX。已从安装了多个程序
他们的来源。安装后发现问题:

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

    • 在安装上述任何文件之前，请重新编译libiconv和gettext没有产生错误，并且都成功安装了多次。
    pkg-config --list-all不显示libiconv或gettext(如果这一切都意味着重要的话)
    libiconv和gettext是它们各自站点的直接副本。

    libiconv v1.14

    尝试在一个简单的libiconv文件中使用.c:
    #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;
}

    如果我没有为-m32指定gcc，那么我将收到以下错误:
    $ gcc -I/usr/local/include -liconv -o test-iconv.exe test-iconv.c

    最佳答案

    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，这篇文章帮助我进行了故障排除和修复:https://www.unix.com/programming/253809-linker-errors-linking-files-os-x.html
