我正在尝试在HP-UX B.11.31 U ia64上构建共享libz.so。遇到以下2个命令时出现问题。我在这里发布命令和configure.log ......................................... .................................................. ...............................

使用./configure -s，CC设置为gcc并且编译＆amp;建立.so。但是1.不是应该选择cc而不是gcc。 2. libz.so：ELF-32共享对象文件 - IA64 - 32位，我想要64位
