Unable to build flutter application for linux

[rolandgeider]

Description

It seems it's not possible to build flutter application for linux

Steps To Reproduce

$ flutter build linux

/home/roland/entwicklung/wger/flutter/linux/flutter/ephemeral/.plugin_symlinks/rive_common/macos/SheenBidi/Source/SBParagraph.c:618:16: error: unused variable 'stringLength' [-Werror,-Wunused-variable]
Building Linux application...                                           
Build process failed

Expected behavior

The build succeds. It seems that 0.13.0 is the version that introduced the bug, it's possible to build the application with 0.12.4 without any problems.

[FeodorFitsner]

Got the same error: https://ci.appveyor.com/project/flet-dev/flet/build/job/8ml3csb67k1mi5dr#L1994

[FeodorFitsner]

0.13.2 introduced that issue. 0.13.1 gives successful build: https://ci.appveyor.com/project/flet-dev/flet/builds/49860784/job/ctoa28981dcvrgg5#L1926

0.13.2 adds rive_common native plugin: flet-dev/flet@4003064#diff-b944988673a542aa817aea9d0faaa93591b3acab9f6b5ca62be94d0b951c8989

Same error with 0.13.1 and latest 0.13.5 on Linux Mint.
Build is OK with 0.12.4 thanks rolandgeider

[KingkorAtMaxint]

This should be higher priority issue. Almost 2 months but no fix is applied for an unused variable warning causing build error. Please update it with a fix.

[FeodorFitsner]

Is there any update? It's still impossible to build the app for Linux with the latest Rive.

[jwinarske]

As a data point I build Rive 0.4.11 (added CMake) for Yocto Linux using this repo:
https://github.com/meta-flutter/rive-common/

The install target also installs a package config file.

This Yocto recipe supports both GCC 13 and Clang 18:
https://github.com/meta-flutter/meta-flutter/blob/scarthgap/recipes-graphics/rive/rive-text_0.4.11.bb

[wenyue]

Same issue, please fix this bug.

[caseymdk]

You can get around this by adding -Wno-unused-variable and -Wno-unused-function flags after the existing -Werror flags on this line of your CMakeLists.txt file in the linux directory.

target_compile_options(${TARGET} PRIVATE -Wall -Werror -Wno-unused-variable -Wno-unused-function)

Those flags are already in the clang build command for rive and the SheenBidi dependency...I don't know why I have to add the flags to my global flutter linux config in order to make things work.

Running with flutter build linux -v shows the particular clang command causing the error. Maybe someone has insight as to why it still throws the error despite those two -Wno flags already being included.

Same issue here, 0.13.20 has same issue, cannot build on linux, I'm trying to build with 0.12.4, it's removing rive_common and it can be build successfully. Please fix this issue ASAP
