but I changed it do a static library and removed the dll export things. Then I want to use this library in a C++ project. I wrapped an extern "C" around the include of the header files to eliminate name mangling. However, I got linker errors for the library functions (undefined ...

中端将GENERIC,利用gimplifier技术,简化GENERIC的复杂结构,将其转换为一种中间表示形式称为:GIMPLE,再转换为另一种SSA(static single assignment)的表示形式也是用于优化的,GCC对SSA树执行20多种不同的优化。经过SSA优化后,该树将转换回GIMPLE形式,用来生成一个RTL树,RTL寄存器转换语言,全称(register-transfer language...
如:undefined reference to `curl_easy_setopt@CURL_OPENSSL_3' 方案1:通过安装libcurl3 libcurl-openssl1.0-dev来解决。 方案2:如果开发者想不想使用低版本的openssl(如Ubuntu 18.04), 可以link静态库easyedge_static.a,自己指定需要的Library的版本: 示例:修改CMakeList.txt find_package(CURL REQUIRED) target_li...
static mut errno: i32; } 1. 2. 3. 4. 当指定的ABI是"C "时,它可以不写: extern {}是隐含的extern "C" {}。 确保这些符号的存在是链接器的责任。此外,还必须注意在边界上发送哪些类型。更多细节见https://doc.rust-lang.org/reference/items/...
