make command does not recognize .o File format

Question

I'm trying to install a software using make on Ubuntu. The software is called Kakadu. I'm following the installing instructor in here. On command make -f Makefile-Linux-x86-64-gcc , I get this error:

params.o: file not recognized: File format not recognized
collect2: error: ld returned 1 exit status
make: *** [libkdu_v77R.so] Error 1

Since I do have g++ installed, why is params.o not recognized but other .o files were ok?

Answer 1

Run:

make -f Makefile-Linux-x86-64-gcc clean
