Bug#978028: opencv: FTBFS on architectures without java

[Pino Toscano]

Source: opencv
Version: 4.5.1+dfsg-1
Severity: important
Tags: patch

Hi,

opencv 4.5.1+dfsg-1 fails to build on architectures without Java
support, like hurd-i386 [1].

This is because the libopencv4.5-java binary was changed from arch:all
to arch:any in version 4.5.1+dfsg-1, so on architectures without Java
the files to install in libopencv4.5-java are not found.
The solution is to restrict the architecture of the libopencv4.5-java
binary to the same list of architectures of the other Java-related
binary, i.e. libopencv4.5-jni. Patch attached for this.

Thanks,
