I switched to the most recent GNU toolchain, building it from source on Fedora 13. Now I am unable to build the simple uart test program bundled with minsoc. I get an error about undefined reference to XXX in function YYY. Function XXX is in reset.S while function YYY is in except.S and visa-versa. It looks to me that the problem is in the linker command, specifically the -T switch doesn't seem to work as it did before.

Hi firefalcon,

How are you compiling your program. It looks like it isn't picking up the C run-time initialization. For simple use or32-elf-gcc -mor32-newlib ... would be appropriate with Or1ksim. There is also -mor32-newlib-uart if you have a UART device in Or1ksim. I know others have worked/are working on board specific ports of newlib.

The problem was fixed by removing the underscore prefixes from referenced functions in reset.S and except.S. Thanks to Raul, minsoc maintainer, who gave me the heads-up on the issue when using newer versions of the toolchain.

I have a couple of problems in a bare-metal compilation with the new tool chain.

1) -mor32-newlib is not working.
2) The _ prefix errors. I recall this problem and its explanation in a different thread but cannot find it in the forum :(

I built only the newlib version and not the Linux kernel version.

Please tell me how to get rid of these.

Sorry for repeated posts, browser problem wasn't letting me see the submission. Can't find a way to delete though !

Some more info @previous post. I am using " or1ksim-0.5.0rc2 " and the tool chain is built from source as per the instructions in http://opencores.org/openrisc,gnu_toolchain#download . Also in the previous toolchain a bare-metal execution involved a command of type " or32-elf-sim --memory=64M ". Is that necessary in this case too ?

It compiled with the -mnewlib flag.

Hi shamikgmg

You have discovered that -mor32-newlib has been replaced -mnewlib. There is also a new option -mboard=, which can be used to link in a newlib BSP for a specific board. The default uses a BSP suitable for Or1ksim.

Longer term, the requirement to specify -mnewlib will go. It will be implicit if you use the or32-elf tool chain. It is a relic from the time when this also was a tool chain for Linux applications, but this is now a separate or32-linux tool chain.

Thank you Jeremy.

hi,
i have the same problems with firefalcon.
after compiling gcc successfully, i wrote a simple hello.c like this
//hello.c
#include "stdio.h"
int main()
{
printf("hello\n");
return 0;
}

using gcc of the OS like this: gcc hello.c -o hello
compilation ok, and hello excute, output hello

using or32-elf-gcc hello.c -o hello
it gives many errors like firefalcon has met.
and the strange thing is that, the error information not only indicate the error from my toolchain install directory, e.g. /tools/openrisc/or32/lib/gcc/or32-elf/lib, but also from the directory where newlib source file located in:/home/czzheng/work/newlib_1.18.0_or32_1.0rc2/newlib/libc/stdlib

after adding -mnewlib parameter like your post said, then, the error message shorten to 2 lines:
or32-elf-gcc -mnewlib hello.c -o hello
/tools/openrisc/or32/lib/gcc/or32-elf/4.5.1-or32-1.0rc4/ctrbegin.o: in function '__do_global_dtors_aux': crtstuff.c: undefined reference to '__deregister_frame_info'
and in funcition 'fram_dummy' there is similar error info.

i want to know where i can find the parameters like -mnewlib, i mean or32-elf-gcc specific, because if i type:
or32-elf-gcc --help, i can only see information about standard gcc, not about gcc of or32.

hope to hear any comment
thanks !

Hi czzheng,

OK - this proves you have a good test program.

So, the version of the compiler you are using requires -mnewlib. The two errors you are getting look like the basic libgcc is not being linked in. Could I ask you to try two things.

1. Build the tool chain from the latest source in SVN. In this version, you should not need to specify -mnewlib. The compiler knows to use newlib as the C library with the or32-elf- toolchain.

2. If you still get errors, please rerun your or32-elf-gcc command, adding -v to the command line and post both the complete command line and the output here.

This is a bug. --help should work, and these should also be added to the documentation (a separate bug). Would you file these in bugzilla, so we can get them fixed.

Thanks,

Jeremy

hi,Jeremy
i am now trying to build new toolchain using the latest code from svn.
binutils 2.20.1 passed(last time i use binutils 2.18), but when compiling gcc 4.5.1, errors like this come:
../gcc4.5.1/libssp/ssp.c O_RDONLY undeclared
and there are more undeclared errors,e.g, size, sszie_t.

the compiling cmd are the same between these 2 try.
so, the latest version are not stable now?

as you said, i am trying to file a bug in bugzilla, but i can not login use the opencores web account, so what the account and password are?
