Hi Folks, I'm keen to try out transparency, on SuSE 10.1 86_64 so I got the latest CVS: cvs -z3 -d:pserver:ano...@gn...:/cvsroot/gnuplot co -P gnuplot and did the following: ./prepare ./configure --with-readline=gnu --enable-history-file make and make fell over: ... if gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../term -I../term -DBINDIR=\"/usr/local/bin\" -DX11_DRIVER_DIR=\"/usr/local/libexec/gnuplot/4.2\" -DGNUPLOT_PS_DIR=\"/usr/local/share/gnuplot/4.2/PostScript\" -DCONTACT=\"gnu...@li...\" -DHELPFILE=\"/usr/local/share/gnuplot/4.2/gnuplot.gih\" -I/usr/X11R6/include -I/usr/include -g -O2 -MT graphics.o -MD -MP -MF ".deps/graphics.Tpo" -c -o graphics.o graphics.c; \ then mv -f ".deps/graphics.Tpo" ".deps/graphics.Po"; else rm -f ".deps/graphics.Tpo"; exit 1; fi graphics.c: In function ‘place_rectangles’: graphics.c:1415: error: expected expression before ‘else’ graphics.c:1433: error: ‘clip_x’ undeclared (first use in this function) graphics.c:1433: error: (Each undeclared identifier is reported only once graphics.c:1433: error: for each function it appears in.) graphics.c:1437: error: ‘clip_y’ undeclared (first use in this function) graphics.c:1442: error: continue statement not within a loop graphics.c:1451: error: continue statement not within a loop graphics.c:1454: error: ‘lpstyle’ undeclared (first use in this function) graphics.c:1459: error: ‘fillstyle’ undeclared (first use in this function) graphics.c: At top level: graphics.c:1481: error: expected identifier or ‘(’ before ‘}’ token make[3]: *** [graphics.o] Error 1 I appreciate that CVS is in a state of flux, and that you'll probably have fixed this before press send on this message... but I thought I'd let you know anyway! best regards, Richard |

My fault, sorry. Although I did test-build it. I really can't
explain why the test-build worked, but the commited file was
missing a brace. I have a standard patch/build/commit-on-success
script that is supposed to prevent this sort of thing.
Anyhow, I see it's now fixed in cvs.
As an apology, I offer the following test script for
transparency. The output is rather nice in png or wxt.

I was planning to put it on the web site anyhow. It's basically just the hidden2 demo we already have, with different coloring+fill options. =2D-=20 Ethan A Merritt Biomolecular Structure Center University of Washington, Seattle 98195-7742 |
