The full command has always been "set terminal" but gnuplot accepts abbreviations provided they are unique, and "term" is a unique abbreviation for "terminal". On my system, gnuplot 4.2 and 4.3 (CVS) both accept "set term". To double-check, I just downloaded and built the latest official release, version 4.2.3: "set term" works fine. What happens if you open an interactive session with your copy of gnuplot 4.2 and type "set term png"? Please note that "configure" is a generated file, not part of the true source tree. The file to modify is configure.in -- but in fact we do check for gnuplot's PNG support as part of gretl's configuration. Allin.

If that's so, it could cause problems with unresolved symbols. The point is that gretl uses no symbols from libblas; it uses symbols from liblapack, which in turn requires symbols from libblas. The order in which the libraries are given to the linker must reflect this. If you give "-lblas" first, the linker thinks "libblas? We don't need anything from that, just move along". This works for me, but I will check on Windows and with the official gnuplot 4.2.3 release. Allin.
