 |
|
Ran into two erros when installing the gcc version recommended on the bladox site (3.3.2) with my linux host which has gcc 4.1.2.
Error 1:
| Quote: | | ./read-rtl.c:653: error: invalid lvalue in increment |
Solution:
This is a problem relating to casting and required editing two lines as suggested here:
diff -u -r1.1.1.1 obstack.h
| Code: | --- obstack.h 23 Jul 2003 02:42:35 -0000 1.1.1.1
+++ obstack.h 22 Jan 2006 12:41:15 -0000
@@ -423,7 +423,8 @@

if (__o->next_free + sizeof (void *) > __o->chunk_limit) \
_obstack_newchunk (__o, sizeof (void *)); \

Error 2:

Solution:
The xgcc compiler had trouble finding the avr-binutils. Running strace on the failed compile shows it looks for it in <builddir>/gcc/avr/3.3.2/. I'm sure there is a smarter way to solve this but instead of reading man pages I linked /usr/local/bin/avr-as to <builddir>/gcc/avr/3.3.2/as along with the other avr functions in the /usr/local/bin directory.
after this GCC compiled just fine. |
