It seems to be because when you compile function pfdLoadFile_3ds()
with CC, the fuction name is appended with a C++ signature so it's
no longer named pfdLoadFile_3ds (but something like e.g.
pfdLoadFile_3ds__FPc, you may use "elfdump -t objectfile" to see
the modified func name). So pfdFindConverterDSO can't find any function
by the original name. Try using extern "C" { ... } to force off
signatures.
