This command doesn't print any debugging information: gammu --debug textall identify This sort-of works: gammu --debug-file log --debug textall identify It creates the log file, but then it leaves in empty and prints the debugging information on stderr. Huh?
close -1 thanks I think that is normal, the upstream project provided those debug features for dev builds only, while the Debian packaging is a release one. As per me it does not make sense to change the Debian packaging to a much slower debug build.
