Qt Libraries Mac
Jul 04, 2011 Modern Mac OS releases from Mac OS X 10.7 & OS X 10.8 onward default to hiding the users Library directory, this is probably to keep people from accidentally deleting or damaging files that are necessary for OS X Lion & Mountain Lion to function properly. That is fine for novice users, but for some of us, we want to be able to access /Library/ at will. Jan 12, 2020 You can access the hidden Library folder without using Terminal, which has the side effect of revealing every hidden file on your Mac. This method will only make the Library folder visible, and only for as long as you keep the Finder window for the Library folder open. Dec 12, 2016 The User Library folder is hidden by default in MacOS Catalina, MacOS Mojave, macOS High Sierra, and macOS Sierra, but some advanced users may wish to show and access the /Library/ folder, which contains preference files, caches, and application support data.

Qt is the faster, smarter way to create innovative devices, modern UIs & applications for multiple screens. Cross-platform software development at its best. Qt Cross-platform software development for embedded & desktop. But if I delete the folder 'usr/local/Trolltech/Qt-4.8.0' from this mac machine, it runs OK. I believe it's some sort of confusion with libraries. It never happened with Qt 4.7.2 (used before on the same machine and same options) configure options: -fast -no-webkit -universal. The Mac deployment tool can be found in QTDIR/bin/macdeployqt. It is designed to automate the process of creating a deployable application bundle that contains the Qt libraries as private frameworks. The mac deployment tool also deploys the Qt plugins, according to the following rules: Debug versions of the plugins are not deployed. This page discusses various available options for working with Portable Document Format (PDF) en.wikipedia.org documents in your Qt application. Please also read the general considerations outlined on the Handling Document Formats page. Qt for macOS macOS (previously known as OS X or Mac OS X) is Apple's operating system for the Mac line of computers. It's a UNIX platform, based on the Darwin kernel, and behaves largely similar to other UNIX-like platforms.

As shown below, OBS 2.app is the one built from source code has less size compared to that of obs downloaded & installed from online. This created the doubt in my mind, the 'make package', I followed to build 'OBS 2.app' is not bundling qt and ffmpeg's libavcodec libraries inside the package.
Maiskar-Apparao:build maiskar$ du -ksh /Applications/OBS*
16M /Applications/OBS 2.app
76M /Applications/OBS.app
Library not loaded: /usr/local/opt/ffmpeg/lib/libavcodec.58.dylib
Library not loaded: /usr/local/opt/qt/lib/QtWidgets.framework/Versions/5/QtWidgets
And to get rid of the above errors, I tried reinstalling ffmpeg --with-sdl2 --with-fdk-aac, and along with qt. Then I'm able to install and open the custom built obs application.
My understanding is the online downloaded obs.dmg file has bigger size compare to that of custom built one and also former obs.dmg is install-able and running without installing dependent libraries like qt (or) ffmpeg's libavcodec. But this is not the case with custom built obs 2.dmg, which needs explicit installing of libavcodec and qt manually to open and run it.
It will be really helpful to me, If anyone can guide me how to bundle obs-studio along with dependent libraries like qt and ffmpeg's libavcodec. So that the custom built obs package can be installed & opened in target machine without necessity of installing dependent libraries like qt / libavcodec.
Thanks,
Apparao Maiskar.
