Simply clone this repository and ensure to have all submodules imported as well (e.g. by using git submodule update --init). Then use the project file harbour-fernschreiber.pro to import the sources in your SailfishOS IDE. To build and run Fernschreiber or an application which is based on Fernschreiber, you need to create the file harbour-fernschreiber/src/tdlibsecrets.h and enter the required constants in the following format:
#ifndef TDLIBSECRETS_H
#define TDLIBSECRETS_H
const char TDLIB_API_ID[] = "42424242";
const char TDLIB_API_HASH[] = "1234567890abcdef1234567890abcdef";
#endif // TDLIBSECRETS_H
You get the Telegram API ID and hash as soon as you've registered your own application on https://my.telegram.org.
Moreover, you need to have a compiled version of TDLib 1.8.21 or higher in the sub-directory tdlib. This sub-directory must contain another sub-directory that fits to the target device architecture (e.g. armv7hl, i486). Within this directory, there needs to be a folder called lib that contains at least libtdjson.so. For armv7hl the relative path would consequently be tdlib/armv7hl/lib.
You may just want to download the tdlib.zip from our fork to just use the exact version of the latest official Fernschreiber release. To use it, you need to extract it into your local tdlib/ folder as described above. If so, you're done and can compile Fernschreiber using the Sailfish SDK. If you want to build TDLib for yourself, please keep on reading.
In case you want to use the same codebase which was used to compile the library that is shipped with Fernschreiber, please check out the fork, be sure to use the branch fernschreiber and compile these sources using the following commands (be sure to have the Sailfish OS build engine running):
alias sfdk=~/SailfishOS/bin/sfdksfdk config target=SailfishOS-4.4.0.58-armv7hl(this compiles the sources on SFOS 4.4 and ARM - the target needs to be adjusted according to the running SDK engine and the platform)mkdir buildcd buildsfdk build-initsfdk build-shell cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX:PATH=../tdlib -DTD_ENABLE_LTO=ON ..(in case of compilation issues, try removing the flag-DTD_ENABLE_LTO=ON)sfdk build-shell cmake --build . --target install
You'll find the compiled library in the directory td/tdlib.
Please read the "Local build" section anyway to understand what's going on before continuing. If you want to automatically build your fork on Github, you'll still need to get a Telegram API ID and hash. These are then added as project secrets named TDLIB_API_ID and TDLIB_API_HASH.
By default, only commits to the master branch will be built. You may change that for your fork, but please don't create a pull request to the official repository changing the github action without consulting the Fernschreiber contributors first.
If you push a tag containing the letter "v" (for example "v0.99.3"), a github release will be created allowing easy download of the resulting rpms. If the tag is named for example "pre-0.99.3", the resulting release is marked as a pre-release for testing purposes.
Fernschreiber does only output a few TDLib messages by default. To get its own debug log messages, you can either run a debug build to see all of them or use the environment variable QT_LOGGING_RULES to specify/filter which messages you'd like to see.
Run QT_LOGGING_RULES="fernschreiber.*=true" harbour-fernschreiber to see all messages or replace the * with specific logging categories. You'll find the logging category inside the corresponding .cpp file for backend usage or you can use JS to only see frontend messages.
You can append &> fernschreiber.log to the command to create a text file containing the debug messages.
Please be aware that debug messages will most likely include personal information including (but not limited to) chat content and user ids/names of yourself and all your chat partners. Do not share it publicly and, at your discretion, try to remove private info even from the parts you do share with a trusted person.
If you want to contribute bug fixes, improvements, new features etc. please create a pull request (PR). PRs are always welcome and will be reviewed as soon as possible, but may take some time. :)
