I have a similar problem on Rocky Linux (RHEL8):
When starting smartsvn.sh it simply stopped without error message. In logfile ~//.config/smartsvn/14.4/'~current-log.1736416100924.tmp' I found this error message:
java.lang.LinkageError: Native library version must be at least 1.14.0,but is only 1.10.2 (r1835932) at org.apache.subversion.javahl.NativeResources.init(NativeResources.java:150) at org.apache.subversion.javahl.NativeResources.loadNativeLibrary(NativeResources.java:111) at org.apache.subversion.javahl.types.Version.(Version.java:40) at com.syntevo.smartsvn.i.a(SourceFile:654) at com.syntevo.smartsvn.i.a(SourceFile:287) at com.syntevo.smartsvn.i.a(SourceFile:203) at smartsvn.xJ.run(SourceFile:65)
There is a package subversion-libs-1.10.2 installed, which contains library libsvnjavahl-1.so
Using repoquery --installed --recursive --whatrequires with package subversion-libs however I found out that is needed by others.
