Dogecoin-Qt cannot upgrade Qt on a minor release without breaking support for older systems, and thus preventing operators on these to get important security updates. Therefore, it is important to patch the fixed version of Qt we are stuck with when applicable. This backports important bug fixes from later Qt versions that harden Dogecoin-Qt's internals: - Fix possible heap corruption in QXmlStream see: https://codereview.qt-project.org/c/qt/qtbase/+/236691 - do not attempt to load a library relative to $PWD see: https://codereview.qt-project.org/c/qt/qtbase/+/286795 - Fix specific overflow in qtextlayout see: https://codereview.qt-project.org/c/qt/qtbase/+/476125 - QDnsLookup/Unix: Ensure that both the RDATA and the Record header fields before it fall inside the buffer we have see: https://codereview.qt-project.org/c/qt/qtbase/+/477644 - Fix a crash while parsing an XML file with garbage data see: https://codereview.qt-project.org/c/qt/qtbase/+/471756 https://codereview.qt-project.org/c/qt/qtbase/+/455027 - Fix crash when reading corrupt font data see: https://codereview.qt-project.org/c/qt/qtbase/+/503026
Prerequisites
The depends system is maintained and tested using Ubuntu Focal. Both generic apt packages, and packages specific to the target architecture are required to successfully compile all dependencies. Listed packages are tested and known to work.
Generic packages
sudo apt-get install autoconf automake make binutils ca-certificates curl \
faketime git-core libtool pkg-config python bison
Generic linux: i686-pc-linux-gnu and x86_64-linux-gnu
sudo apt-get install g++-9-multilib gcc-9-multilib
ARM7 32bit: arm-linux-gnueabihf
sudo apt-get install g++-arm-linux-gnueabihf g++-9-arm-linux-gnueabihf \
gcc-9-arm-linux-gnueabihf binutils-arm-linux-gnueabihf
ARM 64bit: aarch64-linux-gnu
sudo apt-get install g++-aarch64-linux-gnu g++-9-aarch64-linux-gnu \
gcc-9-aarch64-linux-gnu binutils-aarch64-linux-gnu
Windows: i686-w64-mingw32 and x86_64-w64-mingw32
sudo apt-get install g++ g++-mingw-w64 mingw-w64 nsis zip
macOS (Intel): x86_64-apple-darwin11
sudo apt-get install g++ cmake imagemagick fonts-tuffy libz-dev libbz2-dev \
libcap-dev librsvg2-bin libtiff-tools python python-dev \
python-setuptools libtinfo5 xorriso
Usage
To build dependencies for the current arch+OS:
make
To build for another arch/OS:
make HOST=host-platform-triplet
For example:
make HOST=x86_64-w64-mingw32 -j4
A prefix will be generated that's suitable for plugging into Bitcoin's configure. In the above example, a dir named x86_64-w64-mingw32 will be created. To use it for Bitcoin:
./configure --prefix=`pwd`/depends/x86_64-w64-mingw32
Common host-platform-triplets for cross compilation are:
i686-w64-mingw32for Win32x86_64-w64-mingw32for Win64x86_64-apple-darwin11for MacOSXarm-linux-gnueabihffor Linux ARM 32 bitaarch64-linux-gnufor Linux ARM 64 bit
No other options are needed, the paths are automatically configured.
Dependency Options: The following can be set when running make: make FOO=bar
SOURCES_PATH: downloaded sources will be placed here
BASE_CACHE: built packages will be placed here
SDK_PATH: Path where sdk's can be found (used by OSX)
FALLBACK_DOWNLOAD_PATH: If a source file can't be fetched, try here before giving up
NO_QT: Don't download/build/cache qt and its dependencies
NO_WALLET: Don't download/build/cache libs needed to enable the wallet
NO_UPNP: Don't download/build/cache packages needed for enabling upnp
DEBUG: disable some optimizations and enable more runtime checking
HOST_ID_SALT: Optional salt to use when generating host package ids
BUILD_ID_SALT: Optional salt to use when generating build package ids
If some packages are not built, for example make NO_WALLET=1, the appropriate
options will be passed to bitcoin's configure. In this case, --disable-wallet.
Additional targets:
download: run 'make download' to fetch all sources without building them
download-osx: run 'make download-osx' to fetch all sources needed for osx builds
download-win: run 'make download-win' to fetch all sources needed for win builds
download-linux: run 'make download-linux' to fetch all sources needed for linux builds
