A build error happens while building fimg2pnm :

gcc -Wall -fpic -g -DDEBUG_LEVEL=0 -lm fimg2pnm.c ../libfloatimg.a -o fimg2pnm 
/usr/bin/ld : ../libfloatimg.a(fimg-math.o) : dans la fonction « fimg_get_maxvalue » :
/home/fgirault/Temp/floatimg/lib/fimg-math.c:27 : référence indéfinie vers « nanf »
collect2: error: ld returned 1 exit status
make: *** [Makefile:37 : fimg2pnm] Erreur 1

Got it: "-lm" shall appears the end like this:

gcc -Wall -fpic -g -DDEBUG_LEVEL=0  fimg2png.c ../libfloatimg.a -lpnglite -lz -lm -o fimg2png

And all works fine ...
