Command-line build with LLVM 3.6

Original Created Oct 28, 2016 | Regeneration Apr 22, 2026

Question

My native project is set to use LLVM 3.6 in Tizen Studio to utilize std::thread functionality. However, when I export a command-line project and build using:

tizen build-native -a arm -c llvm -C Debug

The system defaults to LLVM 3.4, causing the build to fail (since LLVM 3.4 doesn't support std::thread).

Is there a way to explicitly specify the compiler version when performing a command-line build?

Answer

Problem Understanding

The user needs to build a native Tizen project using LLVM 3.6 specifically to support std::thread functionality. The default command-line build uses LLVM 3.4, which lacks this support.

Solution Methods

Verify Available Toolchains
First, check if LLVM-3.6 is available in your toolchain list by running:
```
tizen build-native --help
```
Look for "Supported compiler version" in the output to confirm LLVM-3.6 is listed.
Update Toolchain (If Needed)
If LLVM-3.6 isn't available, update your toolchain using the package manager:
```
package-manager-cli install LLVM-3.6
```
Specify Compiler Version
When building, explicitly specify LLVM-3.6 in your command:
```
tizen build-native -a arm -c llvm-3.6 -C Debug -- ~/your-project-path
```

Code Examples

Example build command with LLVM-3.6:

tizen build-native -a arm -c llvm-3.6 -C Debug -- ~/workspace/my-project

Additional Tips

Ensure your Tizen Studio and CLI tools are up-to-date to avoid compatibility issues.
If the --help option doesn't work as expected, consider updating to the latest version of the command-line tools.
