Hi Keith and Eli Thank you for your help. I will certainly avoid mingwrt-5.3.1, and avoid libmingwex-2.dll like the plague, or at least like covid19. That done I am still unsure about your comment on my link command: gcc -o x03.exe x03.o C:\plplot32\lib\libcsirocsa.a C:\plplot32\lib\ libplplot.a C:\plplot32\lib\libqsastime.a -mconsole -mwindows -lm It produces: C:\Pete\PlPXmpl>x03.exe Plotting Options: < 1> wingcc Win32 GCC device < 2> ps PostScript File (monochrome) < 3> psc PostScript File (color) < 4> xfig Xfig file < 5> null Null device < 6> mem User-supplied memory device < 7> svg Scalable Vector Graphics (SVG 1.1) Enter device number or keyword: 2 Enter graphics output file name: x03.ps C:\Pete\PlPXmpl> and a lovely graphics picture in x03.ps. No error messages. What's not to like? Would you like to see it? If I omit the -mwindows part I get, not surprisingly a set of error messages: C:\Pete\PlPXmpl>gcc -o x03.exe x03.o C:\plplot32\lib\libcsirocsa.a C:\plplot32\lib\libplplot.a

-lm C:\Pete\PlPXmpl>x03.exe C:\Pete\PlPXmpl> Indeed no contradiction, no error messages but no interaction and NO graphics. So in view of your comments I obviously need your help. What would you suggest I write for my linking command? The pair of commands -mconsole -mwindows was suggested in a help text when I first started to use plplot back in the mists of time. Unfortunately I can't find it now but it seems to have been working ok for a long time. Also, perhaps you could give a reference to these Windows commands (presumably they are system .dll's) as I cannot find any specs for them.
