/usr/local/Gambit-C/bin/gsi lorenz.scm *** ERROR IN "lorenz.scm"@36.1 -- /usr/local/Gambit-C/bin/gsi: undefined symbol: ____20_glut_2d_ffi_2e_o1 (load "glut-ffi.o1")
I assume that ____20_glut_2d_ffi_2e_o1 is the symbol. Only problem is I can figure out why it's looking for that symbol, not too mention the curious coincidence that the symbol it's looking for is the name of the file I am trying to load.
Here's a guess... did you rename this file, i.e.
mv glut-ffi.o2 glut-ffi.o1
That will not work. The function ____20_glut_2d_ffi_2e_o1 is generated by the Gambit-C compiler in the file "glut-ffi.o1" and corresponds to the initialization function. It has the "o1" part to distinguish the function from the initialization function ____20_glut_2d_ffi_2e_o2 generated in "glut-ffi.o2", if you happen to want to want to load "glut-ffi.o1" and later "glut-ffi.o2" in the same execution of gsi (some operating systems get confused when there are two functions with the same name).
Another possibility is that your operating system adds a "_" prefix, or suffix to the symbols and the configure script did not detect this (check the definition of the symbols ___IMPORTED_ID_PREFIX and ___IMPORTED_ID_SUFFIX at the end of include/config.h).
