OK, I guess you're not looking on the Dingoo itself, but you move the flashcard out of the Dingoo, into your PC. In that case, change the path, so isntead of /tmp/openmsx-log.txt change it to ./openmsx-log.txt or something. Then it should appear in the same folder.
Thanks for the photos, but if you can read it, please tell me what it says exactly... because I can't, sorry! :S
EDIT: after some image enhancement, I was able to read it. It confirms that openMSX is not properly installed indeed. Please try to do it according to my instructions in my previous post.
