Instructions for installation on MacOS

[bjornte]

Is the application available for installation on MacOS? If so, are there any instructions for how to install it?

If the app is in a finished state, should a link be added to the Wikipedia.org page?

(I'm struggling to understand the GitHub structure, so forgive me for these naïve questions 😊)

In fact, this project began initially to adapt Jorge’s code for Mac OS X PowerPC (up to 10.5) ....
There’s this script

since 0f41682

With small updates, this project can be built easily on the macos sonoma. However, the resulting binary does not behave well. Full screen does not work, and if you get the correct rendering in the first room, you are lucky.

For compilation just install the dependent libraries via homebrew. Fix the two errors in ISM.cpp (by adding const keyword at the line beginning.) and build the game.

autoreconf -f -ii
CXX="g++" CC="gcc" CPPFLAGS="-I/opt/homebrew/include $CPPFLAGS" LDFLAGS="-L/opt/homebrew/lib $LDFLAGS" ./configure --prefix=`pwd`/in --enable-debug --with-allegro5
make
make install

the two errors in ISM.cpp (by adding const keyword at the line beginning.)

which are these two errors ?

which are these two errors ?

ism.cpp, line 127

        char* lastdot = std::strrchr ( nameFromPath( pathToGame ).c_str(), '.' );

shall be

        const char* lastdot = std::strrchr ( nameFromPath( pathToGame ).c_str(), '.' );

ism.cpp, line 201

                char* lastdot = std::strrchr ( filename.c_str() , '.' );

shall be

                const char* lastdot = std::strrchr ( filename.c_str() , '.' );

const is now there

as for why was it needed ?....

c_str () returns const char* (a pointer to constant) not just char* without const,
and the version of std::strrchr (https://en.cppreference.com/w/cpp/string/byte/strrchr) to be used for a const char* first argument returns const char* as well
