Hello, I using the subject development tools, and can't seem to find the libraries I'm suppose to use for stdio (printf, etc.). Does anyone know what directory Macraigor puts them in? Dan showed me how to point ld.exe to the libraries, if I can just figure out where they are. Thanks, Dave _____ From: [email protected] [mailto:[email protected]] On Behalf Of Dan Fowell Sent: Thursday, July 14, 2005 7:34 AM To: [email protected] Subject: RE: [MPC500] Using libraries with GNU C for MPC555 I don't use stdio or printf, but I do link in a library called libc.a (which has sprintf, atoi, and many others). My link command looks as follows: powerpc-elf-ld.exe -g -t --verbose -Trom.lnk -o main.elf startup.o serial.o main.o hdw.o -L../lib -lc It's been a few years, but I think the -L tells it to link in the libraries, I specify the location of the library "../lib" and then I specify which library "-lc" which tells it to link in the c library (there is a libm.a and a libg.a as well). So from where I compile, my libc.a file is back a directory and then in a "lib" folder I created. Hope that helps.

I am having trouble getting ld to find the libraries GNU C is suppose to be using for Stdio. I can't figure out how to set the path so the linker will find the library, and I haven't been able to figure out what the name of the library is that I need to resolve a reference to printf( ). Thanks for any insight you might be able to offer.
