#108 Build failure with Boost 1.85.0

[Michael Cho]

When building with Boost 1.85.0, the following error is seen:

SgStringUtil.cpp:20:20: error: no member named 'normalize' in 'boost::filesystem::path'
    normalizedFile.normalize();
    ~~~~~~~~~~~~~~ ^

According to https://www.boost.org/doc/libs/1_85_0/libs/filesystem/doc/deprecated.html, normalize() has been removed.

[Patrick Näf]

The solution for this particular error is to change

normalizedFile.normalize();

to

normalizedFile = normalizedFile.lexically_normal();

In the meantime, since this bug has been created, Boost 1.89.0 has been released, and with that version there is one more issue that needs fixing in the Fuego source code, in FuegoMain.cpp. The changes can be viewed in this commit:

To make Boost 1.89.0 compile, one probably needs to use a newer C++ language version. The changes to the Fuego source code to support C++20 can be viewed in this commit:
