Hi, I just download the cygwin toolchain from the opencores web, and
try it with the "Hello-UART" test made by Damjan Lampret. During make,
howere, it gives some errors as:
reset.S.5: Warning: rest of line ignored; first ignored character is '.'
reset.S.12: Error: invalid character '.' in mnemonic
..

So is the cygwin toolchain working properly. Does anyone test it ?

thanks

Hello: That is because binutils are not correctly installed or they are not in the PATH.

Hi, Javier, Thank you for the reply. The package I downloaded http://www.opencores.org/projects.cgi/web/or1k/or1k-bin/or32-uclinux- 2003-04-13.cygwin.tar.gz contains all the binutil tools such as or32-uclinux-ar, -as. And I do set the path as required 'PATH=$PATH:/opt/or32-uclinux/bin' But when I compile any simple c program by typing or32-uclinux-gcc -g -c ..., it always gives me some errors like invalid character '.' in mnemonic So which binutil tool may cause this problem ? thanks zhang ----- Original Message ----- From: jcastillojcastillo@o...> To: Date: Sat Dec 11 13:52:05 CET 2004 Subject: [openrisc] Is cygwin toolchain working properly

Zhang, I believe that problem is from the assembler (gas). Thanks, Balaji V. Iyer. zhang_lsv@yahoo.com said:

Yes, I have the same suspicion. Who could help me to generate a correct one ? Nowadays the opencore CVS is not stable. I cannot even download a single directory from it. If anyone has the working cygwin exe, I am very appreciated if he could share it to me. Or if he has the whole downloaded package for or1k toolchain, it is also very helpful ... Thanks in advance. zhang ----- Original Message ----- From: Balaji V. Iyerbviyer@n...> To: Date: Mon Dec 13 21:38:28 CET 2004 Subject: [openrisc] Is cygwin toolchain working properly
uclinux-

And I do set

like

Zhang, The problem is that it is not able to find the path for the gas...check how you set your path. Also google a little, this way you can find some hlep about how other people have set up cross compilers. A keyword to search with be crossgcc. THis should get you started in your journey.

Hi, Matjaz, Attached is the .S file and the original .c file.

i'm guessing this might be a problem with newline chars. Could you do

or32-uclinux-gcc -g -S program.c -o program.S

and send me program.S. the binary package you've installed should work and
it's been tested in several installs...
