Backend DevelopmentC++How to Resolve Linker Errors Caused by std::__cxx11::string and std::string Conversion Inconsistencies?
Resolving Linker Errors for std::__cxx11::string Conversion
Developers working with C 11 libraries that are not configured for it may encounter linker errors related to the conversion between std::__cxx11::string and std::string. Despite attempts to cast, this conversion remains unsuccessful.
Further investigation reveals a potential issue with GCC 5. According to the GCC 5 Release Notes, such linker errors can indicate the use of object files compiled with different _GLIBCXX_USE_CXX11_ABI macro values. This often occurs when linking to a third-party library compiled with an earlier GCC version.
To resolve this issue, the developer can redefine the _GLIBCXX_USE_CXX11_ABI macro to 0 before including any standard library headers. This should fix the linker errors:
#define _GLIBCXX_USE_CXX11_ABI 0 #include <standard_library_headers.h></standard_library_headers.h>
By following this approach, developers can successfully convert between std::__cxx11::string and std::string, even when using libraries that are not C 11 compliant.
The above is the detailed content of How to Resolve Linker Errors Caused by std::__cxx11::string and std::string Conversion Inconsistencies?. For more information, please follow other related articles on the PHP Chinese website!

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
