The version of cairo in WRL6 package set is 1.12.14. For execution of generating SVG formatted graphics with cairo-1.12.14, the result of it is that PNG formatted graphics is generated.
1. Create and build a new platform project.
2. Create a new application project, and do the following steps.
- Add the test C source file to the project. The code of the test C source file is attached to the bottom of this field.
- Set LIBPATH in Valiables in Properties of the project as the following string value.
<Platform Projec dir>/bitbake_build/tmp/work/x86_64-wrs-linux/cairo/1.12.14-r0/sysroot-destdir/usr/lib64/libcairo.so
3. Build the application project, and execute the executable binary of it on the target.
4. For executing the binary, test.svg is generated. And, it contains the following PNG formatted data, and it does not contains SVG formatted data.
