补充一下具体过程，第一次是使用paddle的预编译包,其version.txt如下
GIT COMMIT ID: 4596b9a22540fb0ea5d369c3c804544de61d03d0
WITH_MKL: ON
WITH_MKLDNN: ON
WITH_GPU: OFF
WITH_ROCM: OFF
WITH_ASCEND_CL: OFF
WITH_ASCEND_CXX11: OFF
WITH_IPU: OFF
CXX compiler version: 8.2.0

怀疑是GCC之间不兼容，我用本地GCC又编译了一个paddle_inference_install_dir，其version.txt如下
GIT COMMIT ID: e755c07e6a5c0880e28b3025a7bb41d684850dd3
WITH_MKL: ON
WITH_MKLDNN: ON
WITH_GPU: OFF
WITH_ROCM: OFF
WITH_ASCEND_CL: OFF
WITH_ASCEND_CXX11: OFF
WITH_IPU: OFF
CXX compiler version: 11.2.0

但报错依旧是相同的，遂怀疑是deploy/cpp_infer的问题。

试一下新的代码看看

好的谢谢，我看到release2.6的新提交了我拉取看看，如果不行我再试试dev分支的

在paddleOCR 分支 f9b0aa8dc9f7d18d1a125476d2361d65963e0eb4中，配合paddlepaddle预编译好的包，出现了以下错误：

[sethome2]

笑，想起来之前paddlepaddle的编译优化参数都是-o3，改成-O3，至少能找到链接符号了

[sethome2]

好了，一切正常，我想拉一个请求。。把CMakeList改了，<\strong>-o3这个优化参数为-O3<\strong>。

或许在GCC8.2能正常工作，但是或许能说算一个UB？

[sethome2]

如果有时间我拉一个请求吧，把所有的-o3换成-O3，除了之前cpp_infer的bug，就是这个o3的问题了。感谢管理员的帮助。

[ToddBear]

请问这个问题怎么解决的呢？我把 -o3 改为 -O3 也没用。。。
