Simply clone this repository and ensure to have all [submodules](https://git-scm.com/docs/git-submodule) 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:
Moreover, you need to have a compiled version of [TDLib 1.7](https://github.com/tdlib/td) 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](https://github.com/Wunderfitz/td/releases) 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 encounter strange performance issues on startup (several seconds delay, app seems to do nothing), please be sure to [follow the instructions from the respective GitHub issue](https://github.com/tdlib/td/issues/1322), i.e. let TDLib build SQLite with `-DOMIT_MEMLOCK` and be sure to comment the two lines 22558 (`#ifndef OMIT_MEMLOCK`) and 22567 (`#endif`) in the file `sqlite/sqlite/sqlite3.c`.
Moreover, TDLib 1.7 has issues loading some pinned messages in case the message database is used (which is the case in Fernschreiber). [A small patch](https://github.com/tdlib/td/commit/30d912bd4b145afb8d494b307d37645ffa21ec29) is required to make TDLib work properly in all cases. See [the respective TDLib issue](https://github.com/tdlib/td/issues/1343) for more details.
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](https://github.com/Wunderfitz/td), 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/sfdk`
-`sfdk config target=SailfishOS-3.3.0.16-armv7hl` (this compiles the sources on SFOS 3.3 and ARM - the target needs to be adjusted according to the running SDK engine and the platform)
-`mkdir build`
-`cd build`
-`sfdk 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`)
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](https://docs.github.com/en/actions/reference/encrypted-secrets#creating-encrypted-secrets-for-a-repository) 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](https://docs.github.com/en/actions/quickstart), but please don't create a pull request to the official repository changing the github action without consulting the [Fernschreiber contributors](https://github.com/Wunderfitz/harbour-fernschreiber/issues/162) 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. :)
