# Qt 5.12.3 Universal (Apple Silicon/macOS)
|
||||
|
||||
Purpose: The official Qt 5.12.3 release lacks support for compilation on macOS ARM (Apple Silicon) architectures. This branch provides a patch for Qt 5.12.3 that enables compilation and native execution on macOS ARM64 systems.

Branch Modifications (Differences):
|
||||
This branch is based on the Qt dev branch at commit 8337e20fadddf, which corresponds to the Qt 5.12.3 release state. The following modifications have been applied:
|
||||
## Purpose
|
||||
|
||||
1. qtbase Module:
|
||||
> The official Qt 5.12.3 release lacks support for compilation on macOS ARM (Apple Silicon) architectures.
|
||||
> This branch provides a patch for Qt 5.12.3 that enables compilation and native execution for both Intel (x86_64) and ARM (arm64) architectures, as well as legacy 32-bit Intel (i386).
|
||||
|
||||
Fixed a missing #include <math.h> in libpng to resolve compilation errors.
|
||||
---
|
||||
|
||||
Removed the #error "32-bit builds are not supported" directives and related code in Cocoa platform plugins to enable 32-bit (i386) compilation support on macOS.
|
||||
## 🚩 **Branch Modifications (Differences)**
|
||||
|
||||
Added necessary includes (e.g., #include <CoreGraphics/CGColorSpace.h>) for the macOS graphics stack.
|
||||
This branch is based on the Qt dev branch at commit `8337e20fadddf` (Qt 5.12.3 release).
|
||||
**Key changes:**
|
||||
|
||||
2. qtmultimedia Module:
|
||||
### 1. `qtbase` Module:
|
||||
- **Fixed:** Missing `#include <math.h>` in libpng to resolve compilation errors.
|
||||
- **Removed:** `#error "32-bit builds are not supported"` directives and related code in Cocoa platform plugins to enable 32-bit (i386) compilation support on macOS.
|
||||
- **Added:** Necessary includes (e.g., `#include <CoreGraphics/CGColorSpace.h>`) for the macOS graphics stack.
|
||||
|
||||
Refactored code in the AVFoundation plugin to replace deprecated C++98 functional utilities (std::binary_function, std::unary_function, std::not2) with modern C++11/14 equivalents (lambda functions). This ensures compatibility with modern compilers enforcing the C++17 standard.
|
||||
### 2. `qtmultimedia` Module:
|
||||
- **Refactored:** AVFoundation plugin code replacing deprecated C++98 functional utilities (`std::binary_function`, `std::unary_function`, `std::not2`) with modern C++11/14 equivalents (lambda functions, etc.).
|
||||
|
||||
Summary: These changes ensure Qt 5.12.3 can be compiled for both Intel (x86_64) and ARM (arm64) architectures on macOS, as well as for the legacy 32-bit Intel (i386) target, creating a more universal binary build.

Build Instructions:
|
||||
## 🛠️ **Build Instructions**
|
||||
|
||||
This project uses the build_opensource.sh script to compile Qt libraries for both x86_64 and ARM64 architectures, subsequently merging them into a single Universal 2 (universal) binary.
|
||||
This project uses the `build_opensource.sh` script to compile Qt libraries for both x86_64 and ARM64 architectures, then merges them into a single Universal 2 binary.
|
||||
|
||||
Building Universal Libraries (macOS)
|
||||
1.Prerequisite - Install Identical libxcb: Before running the build script, you must install the exact same version of the libxcb library on both your x86_64 (Intel) and ARM64 (Apple Silicon) machines.
|
||||
### Building Universal Libraries (macOS)
|
||||
|
||||
2.Create a Merged libxcb Library:
|
||||
1. **Prerequisite – Install Identical `libxcb`:**
|
||||
Before running the build script, install the **same version** of the `libxcb` library on both your x86_64 (Intel) and ARM64 (Apple Silicon) machines.
|
||||
|
||||
On each machine, locate the libxcb.dylib file you installed (typically in /usr/local/lib or /opt/homebrew/lib).
|
||||
2. **Create a Merged `libxcb` Library:**
|
||||
- On each machine, locate the `libxcb.dylib` file (usually in `/usr/local/lib` or `/opt/homebrew/lib`).
|
||||
- Use the `lipo` tool to merge:
|
||||
```sh
|
||||
lipo -create /path/on/x86_machine/libxcb.dylib /path/on/arm_machine/libxcb.dylib -output ./lib/libxcb.dylib
|
||||
```
|
||||
- Replace the system library: Copy the universal `./lib/libxcb.dylib` and overwrite the existing `libxcb.dylib` in your library directory (e.g., `/usr/local/lib`).
|
||||
|
||||
Use the lipo tool to merge the two architecture-specific libraries into one universal library:
|
||||
- lipo -create /path/on/x86_machine/libxcb.dylib /path/on/arm_machine/libxcb.dylib -output ./lib/libxcb.dylib
|
||||
3. **Execute the Build Script:**
|
||||
```sh
|
||||
cd qt5.12.3_universal
|
||||
bash build_opensource.sh
|
||||
```
|
||||
|
||||
Replace the System Library: Copy the newly created universal ./lib/libxcb.dylib file and overwrite the existing libxcb.dylib in the library directory on your primary build machine (e.g., /usr/local/lib/). This step is crucial for the universal Qt build to link correctly.
|
||||
### Building a Single Architecture
|
||||
|
||||
3.Execute the Build Script: Run the script to start the compilation process for both architectures and merge the Qt libraries.
|
||||
If you **do not need** a universal library, you can modify the `build_opensource.sh` script to compile for only one architecture (either x86_64 or arm64).
|
||||
Edit the script to comment out or remove the lines for the other architecture.
|
||||
|
||||
cd qt5.12.3_universal
|
||||
bash build_opoensource.sh
|
||||
---
|
||||
|
||||
Building a Single Architecture
|
||||
If you do not require a universal library, you can modify the build_opensource.sh script to compile for only one architecture (either x86_64 or arm64). Edit the script to comment out or remove the build commands for the architecture you don't need.

|
||||
### Build Process
|
||||
|
||||
Linux, Mac:
|
||||
-----------
|
||||
A typical configure & make build process is used.
|
||||
|
||||
cd <path>/<source_package>
|
||||
./configure -prefix $PWD/qtbase <license> -nomake tests
|
||||
make -j 4
|
||||
#### Some relevant configure options:
|
||||
|
||||
Windows:
|
||||
--------
|
||||
- `-release` Compile Qt with debugging off
|
||||
- `-debug` Compile Qt with debugging on
|
||||
- `-nomake tests` Disable building of tests
|
||||
- `-nomake examples` Disable building of examples
|
||||
- `-confirm-license` Automatically acknowledge the LGPL 2.1 license
|
||||
|
||||
Open a command prompt.
|
||||
Ensure that the following tools can be found in the path:
|
||||
* Supported compiler (Visual Studio 2012 or later,
|
||||
MinGW-builds gcc 4.9 or later)
|
||||
* Perl version 5.12 or later [http://www.activestate.com/activeperl/]
|
||||
* Python version 2.7 or later [http://www.activestate.com/activepython/]
|
||||
* Ruby version 1.9.3 or later [http://rubyinstaller.org/]
|
||||
**Example for release build:**
|
||||
```sh
|
||||
./configure -prefix $PWD/qtbase <license>
|
||||
make -j4
|
||||
```
|
||||
|
||||
cd <path>\<source_package>
|
||||
configure -prefix %CD%\qtbase <license> -nomake tests
|
||||
nmake // jom // mingw32-make
|
||||
**Example for developer build:**
|
||||
```sh
|
||||
./configure -developer-build <license>
|
||||
make -j4
|
||||
```
|
||||
|
||||
To accelerate the bootstrap of qmake with MSVC, it may be useful to pass
|
||||
"-make-tool jom" on the configure command line. If you do not use jom,
|
||||
adding "/MP" to the CL environment variable is a good idea.
|
||||
See output of `./configure -help` for more options.
|
||||
|
||||
More details follow.
|
||||
You can build selected modules with their dependencies:
|
||||
`make module-<foo>` (e.g., `make module-qtdeclarative`)
|
||||
|
||||
Build!
|
||||
======
|
||||
---
|
||||
|
||||
A typical `configure; make' build process is used.
|
||||
### Hints
|
||||
|
||||
Some relevant configure options (see configure -help):
|
||||
The submodule repository **qtrepotools** contains useful scripts for developers and release engineers.
|
||||
Consider adding `qtrepotools/bin` to your PATH.
|
||||
|
||||
-release Compile and link Qt with debugging turned off.
|
||||
-debug Compile and link Qt with debugging turned on.
|
||||
-nomake tests Disable building of tests to speed up compilation
|
||||
-nomake examples Disable building of examples to speed up compilation
|
||||
-confirm-license Automatically acknowledge the LGPL 2.1 license.

||||
Example for a release build:
|
||||
(adjust the `-jN' parameter as appropriate for your system)
|
||||
### Building Qt5 from git
|
||||
|
||||
./configure -prefix $PWD/qtbase <license>
|
||||
make -j4
|
||||
See [Building_Qt_5_from_Git](http://wiki.qt.io/Building_Qt_5_from_Git) and README.git for more info.
|
||||
See [Qt_5 reference platforms](http://wiki.qt.io/Qt_5).
|
||||
|
||||
Example for a developer build:
|
||||
(enables more autotests, builds debug version of libraries, ...)
|
||||
---
|
||||
|
||||
./configure -developer-build <license>
|
||||
make -j4
|
||||
### Documentation
|
||||
|
||||
See output of `./configure -help' for documentation on various options to
|
||||
configure.
|
||||
After configuring and compiling Qt, build docs with:
|
||||
```sh
|
||||
make docs
|
||||
```
|
||||
Install with:
|
||||
```sh
|
||||
make install_docs
|
||||
```
|
||||
Docs are installed in `$QT_INSTALL_DOCS`.
|
||||
`qmake -query` will list the path.
|
||||
|
||||
The above examples will build whatever Qt5 modules have been enabled by
|
||||
default in the build system.
|
||||
|
||||
It is possible to build selected modules with their dependencies by doing
|
||||
a `make module-<foo>'. For example, to build only qtdeclarative,
|
||||
and the modules it depends on:
|
||||
|
||||
./configure -prefix $PWD/qtbase <license>
|
||||
make -j4 module-qtdeclarative
|
||||
|
||||
This can save a lot of time if you are only interested in a subset of Qt5.
|
||||
|
||||
|
||||
Hints
|
||||
=====
|
||||
|
||||
The submodule repository qtrepotools contains useful scripts for
|
||||
developers and release engineers. Consider adding qtrepotools/bin
|
||||
to your PATH environment variable to access them.
|
||||
|
||||
The qt5_tool in qtrepotools has some more features which may be of interest.
|
||||
Try `qt5_tool --help'.
|
||||

Documentation
|
||||
=============
|
||||
|
||||
After configuring and compiling Qt, building the documentation is possible by running
|
||||
"make docs".
|
||||
|
||||
After having built the documentation, you need to install it with the following
|
||||
command:
|
||||
|
||||
make install_docs
|
||||
|
||||
The documentation is installed in the path set to $QT_INSTALL_DOCS.
|
||||
Running "qmake -query" will list the value of QT_INSTALL_DOCS.
|
||||
|
||||
Information about Qt 5's documentation is located in qtbase/doc/README
|
||||
or in the following page: http://wiki.qt.io/Qt5DocumentationProject
|
||||
|
||||
Note: Building the documentation is only tested on desktop platforms.
