AlphaMol项目Makefile转CMake适配CxxWrap后出现段错误求助

核心问题点 #

• 缺失项目全量源文件编译规则：原AlphaMol项目除入口AlphaMol.cpp外，Alphacx、Delcx、DataStruct、InOut、Volumes等模块的实现代码均未加入编译，大量符号缺失会直接触发运行时段错误。
• 未对齐原项目编译参数：原Makefile明确指定了C++11标准、O3优化等级、配套警告规则，现有CMake未做对应配置，编译参数不一致会引发未定义行为。
• GMP依赖配置存在逻辑错误：现有GMP检查分支逻辑书写错误，且未将找到的GMP头文件路径加入头文件搜索列表，非标准路径安装的GMP会出现头库版本不匹配问题。
• 安装路径头文件配置错误：INSTALL_INTERFACE配置路径开头多写了斜杠，会被识别为绝对路径，导致安装后无法正确找到头文件。

修正后CMakeLists.txt #

# 补全所有需要编译的源文件，按实际目录结构调整
set(ALPHAMOL_SRCS
  AlphaMol.cpp
  # 示例：批量添加模块源码，根据实际路径修改

  # list(APPEND ALPHAMOL_SRCS ${DELCX_SRCS})
  # 剩余DataStruct、InOut、Volumes模块按同样方式添加
)

add_library(AlphaMol SHARED ${ALPHAMOL_SRCS})

# 链接所有依赖
target_link_libraries(AlphaMol

  stdc++
)

# 头文件路径配置，修正INSTALL_INTERFACE错误斜杠
target_include_directories(AlphaMol PUBLIC

注意事项 #

你需要根据项目实际的目录结构，补全所有模块的源文件到ALPHAMOL_SRCS列表中，所有用到的cpp文件都必须加入编译，否则仍会出现符号缺失导致的段错误。
