Hi, this is my first post I'm trying to compile in debian woody with Tcl/Tk8.4 from www.backports.org. BWidget is 1.3 from woody. Tkimg is compiled from source. This is what I am getting: tatel@ganbo:~/src/therion$ make g++ -c -Wall -DTHLINUX -O2 -o thdate.o thdate.cxx g++ -c -Wall -DTHLINUX -O2 -o thexception.o thexception.cxx g++ -c -Wall -DTHLINUX -O2 -o thbuffer.o thbuffer.cxx g++ -c -Wall -DTHLINUX -O2 -o thmbuffer.o thmbuffer.cxx g++ -c -Wall -DTHLINUX -O2 -o thlogfile.o thlogfile.cxx g++ -c -Wall -DTHLINUX -O2 -o thtmpdir.o thtmpdir.cxx g++ -c -Wall -DTHLINUX -O2 -o thparse.o thparse.cxx thparse.cxx: In function `void thparse_image(char *, double &, double &, double &)': thparse.cxx:756: implicit declaration of function `int round(...)' make: *** [thparse.o] Error 1 What should I do? Thanks, Roman
