@guanzhi 关老师，我同时依赖OpenSSL和GMSSL的时候遇到符号重复的问题，做了上述修改，您看是否可行？ |
|
感谢思路及贡献。建议基于这个思路实现一个自动替换的脚本，可以为项目中所有公开的符号添加前缀，比如 |
|
关老师，也就是说咱们不考虑从源代码层面就保证跟OpenSSL的独立性吗？需要每次都修改？ |
|
这是符号冲突问题，我计划在3.2 或 3.3 版本中引入一组专用于导出的函数接口来解决这个问题。我建议您可以提供一个脚本，统一给所有函数、类型、常量加固定的前缀，给出一个一致的解决方案（而非仅修改冲突的函数名）。 |
好的，明白 |

最新版本加入了初步设计的公共API，参见 include/gmssl/api.h |
