Bus Error


I found a lot of posts regarding this. They talked about Netscape.
I cross-compiled a program from a PC to a SBC. When I ran it, it said "Bus
Error"
Just one curious question, if I have lo in disk space, will it
also come up with this error?
When I first compiled this software (Berkeley DB)
, the final executable was a script file. So I copied
.lib/lt-excxx_example_database_read to the SBC, but now the program on
the SBC had this error. So how to resolve it if even the BDB example
failed, I tried , at build_unix ,typing ../dist/configure --enable-cxx
--prefix=/usr/local --host=armbe-linux
make
make excxx_example_database_load
etc

And another thin' is I had configured before with a previous installation of PC Berkeley DB on
the same installation dir. (frankly, I installed many applications carelessly but didn't have time to fix it)
How was that going to affect the cross compiling installation? is it a
good idea to do so?
How do you see what dependencies (packages) on the system and how do
you check disk space?
remarks: My application runs okay on my PC/Linux.
Thanks
Jack

Bus error is usually very close to 'segmentation fault'. The thing is where it actually failed. If you have a debugger, you may try to run the program in it and see where it occurs. Then, looking in the code, you should be able to tell if it makes sense or not. If not, it's probably a compilation problem.

Edit: One more thing... If a program works on PC/Linux, it doesn't mean it wil run on any other platform. Bugs may actually occur on certain platforms, type sizes change (what can cause problems) etc.
