Building Doxygen using MSYS2 can sometimes result in the error "Failing building CXX object portable.cpp". This error occurs when the C++ compiler used by MSYS2 is unable to compile the source code for the portable.cpp file.
There can be several reasons why the compiler fails to build this object, including:
Missing dependencies: Ensure that you have all the required dependencies installed on your system. You can find the list of dependencies in the Doxygen documentation.
Incorrect version of GCC: Make sure that you have the correct version of GCC installed on your system. The version of GCC required by Doxygen is specified in the documentation.
Incorrect flags: Make sure that the correct flags are passed to the compiler when building Doxygen. Incorrect flags can cause the compiler to fail when building the portable.cpp file.
Compiler bugs: Some compilers may have bugs that prevent them from building certain source files. If you are using a compiler with known bugs, you may need to switch to a different compiler or upgrade to a newer version.
To resolve the issue, try the following steps:
Check that you have all the required dependencies installed.
Ensure that you have the correct version of GCC installed on your system.
Verify that the correct flags are passed to the compiler when building Doxygen.
If the problem persists, try building Doxygen using a different compiler or upgrade to a newer version of the compiler.
If you are still unable to build Doxygen after trying these steps, you may need to seek assistance from the Doxygen community or consult the Doxygen documentation for more information.
It is also worth noting that building Doxygen from source can be a complex process, especially if you are new to building open source software. It is recommended that you seek help from the Doxygen community or from experienced developers if you are having trouble building Doxygen on MSYS2.
Additionally, it is important to follow best practices when building Doxygen from source. This includes keeping your system up-to-date, using the latest version of the software, and carefully following the instructions provided in the documentation.
In conclusion, building Doxygen on MSYS2 can be challenging, but with the right tools and resources, it is possible to overcome any obstacles that you may encounter. By following the steps outlined in this article and seeking help from the Doxygen community, you can build Doxygen on MSYS2 and start using it to generate high-quality documentation for your projects.
