Hi,<br><br>Now I am working on BCC Cross-compiler in order to get the binaries for LEON3 (Google SoC 2007).<br><br>I changed these lines of Makefile ...<br><br>CC = gcc<br>CPP = gcc -E<br><br>... to these :<br><br>CC = sparc-elf-gcc -mv8 -msoft-float
<br>CPP = sparc-elf-gcc -mv8 -msoft-float -E<br><br>The options means:<br>-mv8 : generate SPARC V8 instructions<br>-msoft-float : emulate floating-point<br><br>When I run "make", there is a error:<br>libtool: compile: unable to infer tagged configuration
<br>libtool: compile: specify a tag with `--tag'<br><br>I think the libtool is linking some libraries of gcc instead of sparc-elf-gcc.<br>How can I change this? is it in "configure" file?<br><br>Thanks,<br><br>
André Costa<br><br>PS: I wasn't getting to communicate with the LEON in FPGA by serial interface, but I discovered the problem. The number code of my FPGA was slightly different. The difference was just in mapping of pins. When I changed of FPGA (to a cyclone), I got to run a hello word! For while I am using the cyclone, but after I will need to map all the pins.
