Dear Mr. Green :

My box is fuloong 6004, loongson2f cpu, mips64, little endian, more info see

Here I want install autogen, then needs guile dependency, guile needs libffi, when I install libffi, afterthat I install guile, problem is that undefined ffi_type_pointer, I try to several methods, it still can be ok. I checked the ffi.h is extern, shall I defined the use #define for each one ?


This just looks like libffi isn't being linked to guile at all. Can you verify that libffi was actually built and installed in the right place? Next, I would see what "CCLD guile" is really doing. I'm not sure how guile is built these days, but maybe you just have to add V=1 to the "make" command line.
