C++ 如何使用我从源代码构建的库，而不是为自己的项目编译的库？

我想试试这个。使用“cmake”和“make”从源代码构建它没有问题，它提供的示例都经过了完美的编译和执行。我还进行了

makeinstall

以导出依赖项文件

然后我想使用这个库编译我自己的程序，所以我检索了生成的文件（标题和静态库），将它们添加到一个新项目中，该项目的代码是上给出的第一个示例的副本/粘贴：

下面是用于编译的命令行：

g++ main.cpp -o main -Iinclude -L -lasmjit

出现第一个编译错误：

In file included from include/asmjit/./core.h:2008,
                 from include/asmjit/asmjit.h:27,
                 from main.cpp:1:
include/asmjit/././core/builder.h:375:20: error: function 'asmjit::Error asmjit::BaseBuilder::dump(asmjit::String&, uint32_t) const' definition is marked dllimport
  375 |   ASMJIT_API Error dump(String& sb, uint32_t formatFlags = 0) const noexcept {
      |                    ^~~~

在对lib代码进行一些研究之后，定义

ASMJIT\u NO\u DEPRECATED

宏（请参见上面代码中的第一行注释）可防止此错误再次出现。我怀疑这是一个好主意，因为它可能是以下下一个链接错误的原因：

除了定义这个宏，我找不到防止第一个错误发生的方法，我也不明白为什么链接编辑器找不到引用。我还尝试将这些依赖项（headers+static lib）放在适当的MinGW目录（即全局

include

和

lib

目录）中，但这不会改变任何东西

我如何编译这个程序，这是非常简单的？我还想知道为什么我所做的不起作用，知道这个错误的原因，我将来可能能够处理其他相同风格的人

PS:我在C和C++中管理外部依赖性的经验不多。我在Windows下，使用MinGW和GCC的最新版本。

您缺少

ASMJIT\u STATIC

编译时定义-如果静态使用ASMJIT，则必须定义它。AsmJit将在编译时检查此定义，以设置

AsmJit\u API

宏，该宏将扩展为编译器特定的导入/导出/可见性属性

AsmJit文档（构建说明部分）说[1]：

静态使用AsmJit的项目必须在使用AsmJit的所有编译单元中定义AsmJit_STATIC，否则AsmJit将在AsmJit_API decorator中使用动态库导入。建议在以这种方式使用AsmJit的整个项目中定义此宏

因此，在您的特定情况下，这应该可以解决问题：

g++ main.cpp -o main -Iinclude -L. -lasmjit -DASMJIT_STATIC

注意：文档链接有意链接到索引页，因此在重新组织文档后，它不会成为死链接

我已经解决了MINGW的编译时问题，谢谢！谢谢你的回复！您提出的解决方案似乎只是“保留”用于构建库，而不是用于编译使用它的可执行文件。我已经用

ASMJIT\u STATIC

参数构建了库，尽管如此，我还是尝试了您的解决方案，但不幸的是，在家里，问题再次出现
