OK, I followed those steps and all the output .psc files came out looking fine, but the file "make_examples.out" shows the same error from ld on c, c++, f77, and f95: "ld: cannot find -lltdl" (and ld returns 1 as it did when I was trying my code). I tried compiling my own code with this command as it appeared in the .out file: /usr/bin/gcc sourcefile.c -o targetfile -Wl,-rpath -Wl,/usr/lib64:/ usr/lib64 `PKG_CONFIG_PATH=/usr/lib64/pkgconfig pkg-config --cflags -- libs plplotd` but (unsurprisingly) I got the same error. Additionally, the file "plplot_test.out" contained this: Testing front-end c ./test_c.sh: line 34: ./c/x01c: No such file or directory Testing front-end cxx ./test_cxx.sh: line 32: ./c++/x01cc: No such file or directory ./test_cxx.sh: line 38: ./c++/x01: No such file or directory Testing front-end f77 ./test_f77.sh: line 37: ./f77/x16af: No such file or directory Testing front-end f95 ./test_f95.sh: line 37: ./f95/x16af: No such file or directory Testing front-end java chmod: cannot access `./test_java.sh': No such file or directory /bin/bash: ./test_java.sh: No such file or directory Testing front-end octave chmod: cannot access `./test_octave.sh': No such file or directory /bin/bash: ./test_octave.sh: No such file or directory Testing front-end python PLplot library version: 5.8.0 Testing front-end tcl ./test_tcl.sh: line 29: cd: ./tcl: No such file or directory ./test_tcl.sh: line 30: pltcl: command not found Testing front-end perl chmod: cannot access `./test_perl.sh': No such file or directory /bin/bash: ./test_perl.sh: No such file or directory Testing front-end ada ./test_ada.sh: line 31: ./ada/x01a: No such file or directory So...what does this all indicate, and what's the next step?
