如何解决建立库pgm时发出Clang未定义符号
所以我试图用“ --with-pgm”标签编译一个支持pgm的iOS ZeroMQ库。我当前正在使用此script，只需克隆存储库并运行ruby脚本即可运行。如果查看shell文件，您会看到我已经定义了三种体系结构（arm7，arm7s，arm64），并且已经将pgm标记（--with--pgm）添加到\ configure中。
现在，如果我尝试编译不带pgm标签的库，我将完全能够并且一切正常。
但是，如果我尝试使用pgm标签编译该库，则会得到以下错误列表：
（请注意，在此列表之前，使用brew安装的libpgm出现了结构重新声明的错误，我通过注释掉库中的结构来修复了该结构）

据我所知，clang告诉我zmq库期望存在未定义的pgm内容。目前，在我的计算机上，我安装了libzmq和libpgm，以便在需要时使用Python运行ZeroMQ和PGM。
我看过这个Stack Overflow article时遇到了同样的问题，但是我认为不必在运行时查找符号就可以解决我的问题。
我还发现此article更针对libpgm和ZeroMQ进行了量身定制，但它表示要将OpenPGM库依赖项添加到构建中，我不确定如何使用shell脚本。
我不知道如何从这里开始，但是据我所知，添加OpenPGM库可能是我最好的选择。
