Xcode building the project missing Info.plist file in solvespace app folder?

[ss0git]

That being said it crashes on launch for other reasons. There are two issues I can spot right now, and I think they are related.

• In the solvespace.app folder there are two folders MacOS and Resources. A file that is missing and should be there is Info.plist, it's there in the 'make' build and macOS apps in general have it.

• It seems to fail to find its resources? The file is there in the Resources folder but a missing Info.plist file means the app doesn't have the values it needs to start. Crashes on line:

std::string LoadString(const std::string &name) {
    size_t size;
    const void *data = Platform::LoadResource(name, &size);
    ...

and in platform.cpp

const void *LoadResource(const std::string &name, size_t *size) {
    static std::map<std::string, std::string> cache;

    auto it = cache.find(name);
    if(it == cache.end()) {
        ssassert(ReadFile(ResourcePath(name), &cache[name]), "Cannot read resource");
        ...

The value of the variable name = "locales.txt"

I think your analysis is correct, here's how it's locating the path: https://github.com/solvespace/solvespace/blob/master/src/platform/platform.cpp#L475-L500

Not sure about Info.plist file.

[whitequark]

I have a MacOSXBundleInfo.plist.in file, which should be used for the target that specifies MACOSX_BUNDLE. Not sure what goes wrong there.

Also wow, I had no idea BundleUtilities existed, I did not need to mess with install_name_tool manually after all. Thanks!

[whitequark]

The Info.plist is generated by cmake command and not regenerated if you manually remove SolveSpace.app and call make. As for BundleUtilities, master simply links everything statically now.
