Hi! I'm using Fedora Core 4. I would like to be able to check the ink level of my hp deskjet 3535. There is a library, libinklevel that is supposed to do this. It can be found at: ( http://libinklevel.sourceforge.net/ ) Has anybody compiled this library? When I try to compile it I get the following: [gmata@sucre libinklevel]$ make gcc -Wall -O2 -fPIC -DPIC -I. -c -o epson.o epson.c epson.c: In function ?get_ink_level_epson?: epson.c:49: warning: pointer targets in passing argument 1 of ?sprintf? differ in signedness epson.c:51: warning: pointer targets in passing argument 1 of ?sprintf? differ in signedness epson.c:61: warning: pointer targets in passing argument 1 of ?open? differ in signedness epson.c:140: warning: pointer targets in passing argument 1 of ?strstr? differin signedness epson.c:140: warning: pointer targets in assignment differ in signedness gcc -Wall -O2 -fPIC -DPIC -I. -c -o hp.o hp.c hp.c:14: error: array type has incomplete element type hp.c:15: error: array type has incomplete element type make: *** [hp.o] Error 1 Thanks, Gustavo
