编译后的内置包错误 - C ++

I have been trying to debug these package errors from long and any solutions suggested for it could not solve the problem.

For uint32_t error that is in tesseract package which cannot be altered externally, how shall I solve it.

Can anyone just have a look on it and suggest any suitable solution. Please do help.

我一直在尝试从长时间调试这些包错误,并且建议的任何解决方案都无法解决问题。对于tesseract软件包中的uint32_t错误,无法在外部进行更改,我该如何解决。任何人都可以看看它并建议任何合适的解决方案。请帮忙。

This is my cpp file where these errors occur

1 个解决方案

#1

1. Add the following compiler switch: -std=c++11 or -std=gnu++11 to turn on C++11 features like std::uint8_t.

添加以下编译器开关:-std = c ++ 11或-std = gnu ++ 11以打开像std :: uint8_t这样的C ++ 11功能。

2. QString does not contain a function called "toAscii" so refactor that code.

QString不包含名为“toAscii”的函数,因此重构该代码。
