glib2-devel @2.62.5: does not build on 10.4 Tiger i386

[kencu (Ken)]

looks like SDK-related issues:

Workaround for Tiger/Leopard warnings and errors

[kencu (Ken)]

That's why I'm happy to have some help with these Tiger/Leopard issues! Thanks.

I can see how this would make glib2 compile -- but to consider, rather than just send back "NULL" for all the paths, is there any way we can return a "99%+" right answer of $HOME/Downloads, $HOME/Pictures, etc?

That way, it might do the right thing for us....

[kencu (Ken)]

here is part, perhaps:

$ cat getpath.c
#include <stdio.h>
#include <unistd.h>
#include <sys/types.h>
#include <pwd.h>
#include <assert.h>

int main(void) {
    const char * thePath;

    struct passwd *pw = getpwuid(getuid());
    assert(pw);
    thePath = pw->pw_dir;

    printf("%s\n",thePath);
    return 0;
}

$ gcc-apple-4.2 -o getpath getpath.c
MacMini:~ me$ ./getpath
/Users/me

[evanmiller (Evan Miller)]

I'd suggest taking the result of find_folder (NSDesktopDirectory), removing the last path component, and appending Downloads, Movies, etc.

(Would amend patch but leaving soon for vacation.)

The build still fails due to some test failures having to do with @loader_path.

[kencu (Ken)]

That @loader_path business is all me -- I hacked that into meson to make it work at all on Tiger.

Yeah, if some part of that original code works on Tiger, we can certainly build off that. I thought it was all DOA.

[evanmiller (Evan Miller)]

Just getting the username and returning "/Users/me/Downloads" will work 99% of the time. All of the standard folder names are in English, and are only localized when being displayed.
