Illegal instruction Built bcc
Hi all,
I'm trying to compile and run :
#include <stdlib.h>
int main(){
return 0
}
on a Leon3/Sparc+Linux architecture.
When I compile it with the toolchains binaries provided by Gaisler, it works well (sparc-linux-gcc) it works well
Whereas when I compile it with a toolchain that I have built using the BCC sources, I get an illegal instruction when trying to run it.
Where does that come from please ?

Most likely you configured buildroot for a subarchitecture that is not
supported by your platform. You can run the working cross-compiler with the -v option; in the long list of configure options you'll see something like '--with-cpu=sparcsfleon'. That is the subarchitecture you should use for buildroot too.

Thanks for your answer.
Actually, I use the buildroot package provided by Gaisler on their website to build a Linux for the Leon3 architecture. They provide toolchains binaries as well and also the bcc sources.
So what I have is a working Leon3+Linux architecture on a Virtex5 FPGA card. What I'm trying to do is to compile and run a test program on the Linux. Then comes the issue : when I compile this test code with the cross compiler binary provided, it compiles and runs well on the Linux.
But, when I try to compile it with a cross compiler that I have built using the bcc sources, it fails with the illegal instruction trap.
Here is the output of both -v :
Provided cross compiler : sparc-linux-gcc -v

Oh, so you're trying to build a compiler for a bare (non-Linux) system...
Can't really help with that, I'm afraid... Why are you asking this on the buildroot mailing list?
