Subject: Fix gvconfig_libdir function to report resolved lib directory if -v set.
X-Git-Tag: LAST_LIBGRAPH~32^2~1341
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=06810213a8099362fcfe7174feaa4d62a3fcddca;p=graphviz

Fix gvconfig_libdir function to report resolved lib directory if -v set.
Previously, this was set up to be done on the first call to this function,
but at that time, argv[] hasn't been process, so job->common.verbose had
not yet been set, and nothing is printed.
