Thread: [uml-devel] UML/WIN32 compilation error

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Chandan,

When I try to compile UML/WIN32 according to the instruction in page http://toad.net/~chandan/umlwin32/download.html, but I get the following error message. Did you have this problem ? After I checked the make file and I found it is because a command "rev" cannot be found.
