RE: [avr-gcc-list] Warnings with virtual methods in avr-g++

Hi Steve, Sorry, I don't know where you could start looking for that. I don't think that Joerg and I have had much of a chance to delve into C++ at all. So if you started looking into it, you would be the 'resident expert'. ;-) Eric ___ AVR-GCC-list mailing list AVR-GCC-list@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
Re: [avr-gcc-list] Warnings with virtual methods in avr-g++
Hello, I expect that this error message stems from the assembler. Try to compile the sources with -S and I expect that you won't see this error. I expect that the virtual tables are aligned on a 4-byte boundary (as usually is useful for 32 bit systems). Bjoern. Thanks for your time Bjoern, I tried with -S option, but the warning continue tu appear: avr-g++ -S ieee1451dot1/types/ObjectTag.cc ieee1451dot1/types/ObjectTag.h:20: warning: alignment of 'ieee1451dot1::types::ObjectTag::_ZTVN12ieee1451dot15types9ObjectTagE' is greater than maximum object file alignment. Using 1 Sorry, that's a known issue. Have it still in the latest 4.1.x build on my unix. I think the problem is due to the 8-bit nature of the avr. I have been getting it for several years, with no bugs traceable to it, so it appears harmless. There is no c++ maintainer for avr-g++ currently, so it should persist...

Steve These are good news :). It's good to know that the warnings seems to not produce collateral problems. In my tests, my software seems to run run well too.

[avr-gcc-list] Warnings with virtual methods in avr-g++
Hello all, I'm getting an extrange warning in all classes that have virtual methods when compiling with AVR-G++ (version 3.4.6): aligment of 'x' is greater than maximum object file aligment Somebody could explain me this error? Searching on google I found that there is a bug posted in the bugzilla por GCC with this issue, somebody knows if this is solved in recent versions of GCC (4.x)? (I'm using Nut/OS and Ethernut, and it doesn't compile under GCC 4.x) Finally, the program seems to run well even with the warnings, but they are very annoying :D Thanks in advance. Best regards.
