I tried to build and run a Qt5 (5.15.2) application on macOS (10.15.7) using Bazel 5.0.0.
Unfortunately, I run into some problems.
The building part seems to work, but not the run part.
I installed Qt5 on my machine using Homebrew:
brew install qt#5
brew link qt#5
I adapted https://github.com/justbuchanan/bazel_rules_qt/ to my needs. See this PR. When I try to run:
bazel run --cxxopt=-std=c++17 //tests/qt_resource:main
I receive the runtime error:
dyld: Symbol not found: __ZN10QByteArray6_emptyE
Steps to reproduce the issue:
# brew install bazel # Install Bazel
# brew install qt#5 # Install Qt5
git clone https://github.com/Vertexwahn/bazel_rules_qt.git
cd bazel_rules_qt
git checkout add-macos-support
bazel build --cxxopt=-std=c++17 //... # should work
bazel run --cxxopt=-std=c++17 //tests/qt_resource:main # should give you the error message
Nevertheless, building everything using bazel build --cxxopt=-std=c++17 //... seems to work.
I am not 100% sure if the link options -F/usr/local/opt/qt5/Frameworks and -framework QtCore, etc. are correct.
Maybe someone can confirm this.
Did I use the correct link options?
For me, it is a bit unclear what dependencies the main binary expects. I tried to copy QtCore.framework to the location of the main binary manually but this does not change the error message.
What files does the main binary expect?
If I try to run macdeployqt on my main binary I get also some errors. I do within my workspace root dir a cd bazel-bin/tests/qt_resource and run then /usr/local/opt/qt5/bin/macdeployqt main:
ERROR: Could not find bundle binary for "main"
ERROR: "error: /Library/Developer/CommandLineTools/usr/bin/otool-classic: can't open file: (No such file or directory)\n"
ERROR: "error: /Library/Developer/CommandLineTools/usr/bin/otool-classic: can't open file: (No such file or directory)\n"
ERROR: "error: /Library/Developer/CommandLineTools/usr/bin/otool-classic: can't open file: (No such file or directory)\n"
WARNING:

WARNING: If so, you will need to rebuild "main" before trying again.
ERROR: Could not find bundle binary for "main"
ERROR: "error: /Library/Developer/CommandLineTools/usr/bin/strip: can't open file: (No such file or directory)\n"
ERROR: ""
My hope was that macdeployqt would collect all needed resources for me. Any idea why this is not working?
How can macdeployqt be used to collect all needed dependencies for the main binary?
If I convert my main to an app via lipo -create -output universall_app main and do then a /usr/local/opt/qt5/bin/macdeployqt universall_app I get the same error message.
The CMake approach
To make sure that there is no general problem with my system setup I tried to use CMake to build a Qt5 application:
git clone https://github.com/euler0/mini-cmake-qt.git
cmake -DCMAKE_PREFIX_PATH=/usr/local/opt/qt5 .
make -j
This produces an example.app.
With a double click on this application bundle,
the application can be started.
This worked on my system.
Future directions
It seems that rules_apple can be used to create an application bundle.
I am not sure if I need to transform my Qt application binary to an app bundle to be able to execute it.
One could use --sandbox_debugto identify what Bazel is doing and dtruss for the CMake version to compare the differences.
I am currently not sure what trying to do next and hope for an easy solution. I am also fine with a Qt6 solution.
Update: Alternative Answer
It would also be helpful if someone can point out how to build a minimal Qt application using make only on macOS and a brew installed Qt5 or tell me what the linker and compiler options must look like.
I followed your steps with Mac OSX 10.15.7, Qt (installed by homebrew) 5.15.1 and both bazel 4.2.2-homebrew and 5.0.0-homebrew and initially I could not build the project from git:
* 3fe5f6c - (4 weeks ago) Add macOS support — Vertexwahn (HEAD -> add-macos-support, origin/add-macos-support)
This is the result that I get when building:

Related to your question whether the linker options are correct
-F/usr/local/opt/qt5/Frameworks -framework QtCore
Yes they are correct, you could alternatively use -F/usr/local/opt/qt5/lib (as you are already using in qt.BUILD) as all the files under the Frameworks folder are links to the lib folder.
With macdeployqt and lipo I get the same results as in the OP even after the test is running successfully.
I've checked out the Boost library (v1.68.0) from https://github.com/boostorg/boost.git and performed the usual git submodule init and git submodule update. I'm interested in building a statically linked, single-threaded version of the library. So I run:
./bootstrap.sh && ./b2 link=static threading=single
But this fails (see output below). What am I doing wrong?

* Solution *
I forgot to update submodules, my fault
No that is really strange!
What commands are you passing to build? (or is that literally the default?)
I recommend trying out one of my build scripts here:
https://github.com/danoli3/ofxOSXBoost
If that doesn't work either it may be a system conflict.
Do you have Homebrew or Macports installed? See if they have a Boost version installed.
I'm trying to build the Carbon Platform from source.
I've tried this:
svn co https://svn.wso2.org/repos/wso2/carbon/platform/branches/4.0.0
cd patch-releases\4.0.9
set MAVEN_OPTS="-Xms512m -Xmx1024m -XX:MaxPermSize=1024m"
mvn clean install -Dmaven.test.skip=true
However, I had hit this problem: link
After fixing that problem, I have now run into this:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0:compile (default-compile) on project org.wso2.carbon.message.store: Compilation failure: Compilation failure:

arbon\message\store\persistence\jms\JMSMessageStore.java:[29,39] cannot find symbol
[ERROR] symbol : class MessageStores
[ERROR] location: package org.apache.synapse.message.store
I must be doing something wrong - I keep hitting errors at each turn?
Question: What are the steps needed to build WSO2 Carbon Platform Patch Release 4.0.x?
The necessary steps are, (if you want to build patch-release 4.0.x)
1) build orbit 4.0.0/
Then build orbit/patch-release/4.0.x
2) build kernel 4.0.0/
Then build kernel/patch-release/4.0.x
3) build platform 4.0.0/
Then build platform/patch-release/4.0.x
This should work.
While building the project in Maven 2.2.1 as some of my projects are in JDK1.6 and some in JDK 1.7.I need to build the entire modules.
What are the changes shall I need to make as I am getting the below error:
