#### General notes
|
||||
* The make option ```-j``` can be used for concurrent compilation.
|
||||
* ```LIB_SUFFIX```, ```LIB_SUFFIX_32``` and ```LIB_SUFFIX_64``` can be set to
|
||||
specify a suffix for the library directory, eg. lib*64* or lib*32*. The 32/64 variants are only used when building for 32/64-bit architecture.
|
||||
* By default the build system will *build* static libs. To *build* shared libraries *instead*, set `BUILD_SHARED_LIBS=ON`.
|
||||
* By default the build system will prefer *linking against* shared libraries. To force *linking against* static libraries set `STATIC_LINKAGE=ON`.
|
||||
However, this will only affect applications. To force linking statically when building shared libraries set `STATIC_LIBRARY_LINKAGE=ON`.
|
||||
* If thread local storage is not supported by your compiler/platform (might be the case on MacOS), you can disable making use of it
|
||||
via `ENABLE_THREAD_LOCAL=OFF`.
|
||||
* To disable use of `std::filesystem`, set `USE_STANDARD_FILESYSTEM=OFF`. This is required when building for MacOS and Android at the time of
|
||||
writing this documentation. Note that the Bash completion will not be able to suggest files and directories with `USE_STANDARD_FILESYSTEM=OFF`.
|
||||
* To disable `NativeFileStream` (and make it just a regular `std::fstream`), set `USE_NATIVE_FILE_BUFFER=OFF`. Note that handling paths with
|
||||
non-ASCII characters will then cease to work on Windows.
|
||||
* ```LIB_SUFFIX```, ```LIB_SUFFIX_32``` and ```LIB_SUFFIX_64``` can be set to specify a suffix
|
||||
for the library directory, eg. lib*64* or lib*32*. The 32/64 variants are only used when building

|

Note that handling paths with non-ASCII characters will then cease to work on Windows.
|
||||
* The Qt-based applications support bundeling icon themes by specifying e.g.
|
||||
`BUILTIN_ICON_THEMES=breeze;breeze-dark`.
|
||||
* This variable must be set when building the application (not when building any of the libraries).
|
||||
* The specified icon themes need to be installed in the usual location. Otherwise, use e.g.
|
||||
`DBUILTIN_ICON_THEMES_SEARCH_PATH=D:/programming/misc/breeze-icons/usr/share/icons` to specify the
|
||||
search path.
|
||||
* For more detailed documentation, see the documentation about build variables (in
|
||||
[directory doc](https://github.com/Martchus/cpp-utilities/blob/master/doc/buildvariables.md) and
|
||||
in Doxygen version accessible via "Related Pages").
|
||||
* The repository [PKGBUILDs](https://github.com/Martchus/PKGBUILDs) contains build scripts for GNU/Linux, Android, Windows and
|
||||
MacOS X in form of Arch Linux packages using `ninja`. These scripts can be used as an example also when building under/for other platforms.

|
||||
|
||||
#### Windows-specific notes
|
||||
* To create application icons the tool `ffmpeg`/`avconv` is required.
|
||||
* Windows builds are only conducted using mingw-w64/GCC. Using MSVC has never been tested.
|
||||
* Windows builds are mainly conducted using mingw-w64/GCC so using them is recommended. Building with MSVC
|
||||
should be possible as well but it is not as well tested.
|
||||
* When using `BUILTIN_ICON_THEMES`, the icon theme still needs to be installed as if it was installed on a
|
||||
GNU/Linux system. So simply grab e.g. the Arch Linux package `breeze-icons` and extract it somewhere. Do
|
||||
*not* use the package from MSYS2 or what comes with builds from KDE's binary factory.
|
||||
|
||||
#### MacOS-specific notes
|
||||
* To create application icons the tool `png2icns` is required.
|
||||
* Building for MacOS X under GNU/Linux is possible using [osxcross](https://github.com/tpoechtrager/osxcross).
|
||||
* MacOS X builds are not tested regularly but should generally work (maybe with minor tweaks necassary)
|
||||
* There is a [Homebrew formula](https://gist.github.com/rakkesh/0b13b8fca5dd1d57d98537ef1dd2e0dd) to build Tag Editor (without GUI)
|
||||
* There are [MacPorts packages](https://www.macports.org/ports.php?by=name&substr=syncthingtray-devel) to build Syncthing Tray

#### Development builds

During development I find it useful to build all required projects (for instance c++utilities, qtutilities, tagparser and tageditor) as one big
|
||||
project.
