files-app does not compile on OSX

[nbigaouette]

There seems to be a mount helper included in files-app but this is not supported under OSX.

Trying to compile it I get the following error:

make

I simply deleted everything related to mtab for files-app to compile:

Maybe it can be added a wrapper with ifdef to use getmntinfo[1] instead on OS X?
https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man3/getmntinfo.3.html

[nbigaouette]

Sure, the linux only feature should be at least isolated using #ifdefs if the app is meant to be portable to other platforms.

[dcfranca]

I'm trying to wrap the mount helper to work both on Linux and OSX, the app is compiling, but when I try to run it I receive the following error: main.qml:23 module "org.nemomobile.folderlistmodel" is not installed

Any idea how can I solve it? I already tried to add the folderlistmodel path to the QML2_IMPORT_PATH env var, but it didn't help.

[nbigaouette]

I have the same problem. Actually I've never been able to run files-app, neither on linux nor osx.

On OSX, I get the following:

./src/app/papyros-files
Trying to load QML from: "/Users/path/to/files-app.git/build/src/app/qml/main.qml"
QQmlApplicationEngine failed to load component
file:///Users/path/to/files-app.git/build/src/app/qml/main.qml:23 module "io.papyros.folderlistmodel" is not installed

Might be the same error on linux (can't remember, can check tomorrow).

I think I've seen another bug report about the folderlist module missing.

Also, note that in the error above I have run papyros-files from the build dir. When installing with make install I have rpath problems:

$ /usr/local/bin/papyros-files
dyld: Library not loaded: @rpath/QtQuick.framework/Versions/5/QtQuick
  Referenced from: /usr/local/bin/papyros-files
  Reason: image not found
Trace/BPT trap: 5

from which I tried to fix using:

$ ldd /usr/local/bin/papyros-files
/usr/local/bin/papyros-files:

$ install_name_tool -change @rpath/QtCore.framework/Versions/5/QtCore /Users/me/Qt/5.5/clang_64/lib/QtCore.framework/Versions/5/QtCore /usr/local/bin/papyros-files

but then I get:

$ /usr/local/bin/papyros-files
This application failed to start because it could not find or load the Qt platform plugin "cocoa".

Available platform plugins are: cocoa, minimal, offscreen.

Reinstalling the application may fix this problem.
Abort trap: 6

[ricardomv]

@nbigaouette I can't help you much because i never worked with OS X but on linux i would delete everything installed in /usr/local listed in install_manifest.txt. clean the build directory and install with the following commands.

cmake -DCMAKE_INSTALL_PREFIX=/usr ..

@DanielFranca i think the same would work for you. Specially because in current master org.nemomobile.folderlistmodel is called io.papyros.folderlistmodel

[dcfranca]

After update my master with the current master, I could figure out how to solve this specific problem.
I'd to include the libtag again, and then fix manually the files:
folderlistmodel.dir/link.txt and CMakeFiles/folderlistmodel.dir/flags.make

Because the path for taglib includes/libs was wrong/missing in those files, so the folderlistmodel was not being compiled.

After that it was compiled, but then I got some errors trying to run files-app, errors saying that it was not finding the QtQuick libraries to load: dyld: Library not loaded: @rpath/QtQuick.framework/Versions/5/QtQuick

To fix that I copied the libraries to the executable path, following the dir structure, like:
./QtQuick.framework/Versions/5/QtQuick

But now I receive the error: This application failed to start because it could not find or load the Qt platform plugin "cocoa".

Tried to copy the cocoa lib to the structure: ./plugins/platforms/libqcocoa.dylib

No success, for now I'm done, if anyone has any other idea to make it work let me know
