Dear Matt, I checked the log file but didn't see any error message. I don't know if it's because I succeeded in installing Athena and Artemis following Carlo's suggestion and the log file is thereby updated. Here's the content of the log file: "#!/bin/sh # PGPLOT install log # system = linux == linux g77_gcc # prefix = /usr/local/ # fortran compiler = gfortran gzip -dc pgplot5.2.tar.gz | tar xf - mkdir -p /usr/local//share/ifeffit/pgplot/ # driver.list written to /usr/local//share/ifeffit/pgplot//drivers.list # starting build cd /usr/local//share/ifeffit/pgplot// rm -f grfont.dat pgplot.doc pgxwin_server lib*pgplot* pgdemo* /home/enyuan/ifeffit-1.2.11d/pgplot/makemake /home/enyuan/ifeffit-1.2.11d/pgplot linux g77_gcc # customizing grgil.f for ifeffit sed 's|/usr/local/pgplot/|/usr/local//share/ifeffit/pgplot/|g' /home/enyuan/ifeffit-1.2.11d/pgplot/src/grgfil.f > /home/enyuan/ifeffit-1.2.11d/pgplot/src/grgfil_iff.f mv makefile Tmp sed 's|grgfil|grgfil_iff|g' Tmp > makefile sed 's|libpgplot|libpgplot_iff|g' makefile > Tmp sed 's|-lpgplot|-lpgplot_iff|g' Tmp > makefile # customizing xwdriv.c for ifeffit sed 's|getenv("PGPLOT_DIR")|'"/usr/local//share/ifeffit/pgplot/"'|g' /home/enyuan/ifeffit-1.2.11d/pgplot/drivers/xwdriv.c > /home/enyuan/ifeffit-1.2.11d/pgplot/drivers/xwdriv_iff.c mv makefile Tmp sed 's|xwdriv|xwdriv_iff|g' Tmp > makefile # fix png driver mv makefile Tmp sed 's|pndriv.o : ./png.h|#### pndriv.o : ./png.h|g' Tmp > makefile make FCOMPL= gfortran FFLAGC=-O1 libpgplot_iff.a make FCOMPL= gfortran grfont.dat prog pgplot.doc pgxwin_server cpg make clean " I hope the length is not too bothering and thank you very much for the help! -- Enyuan
