I try to follow way. I applied patch file to rtl-host and re-build. But result is same.<br>
<br>
It seems to do not include gcc libraries.<br>
<br>
I include __floatsisf function in my base rtems. so that error do not occurs, but other symbol could not find.(__gesf2)<br>

Did you use the same options to rtems-ld as gcc when linking ?<div class=""><br>

But, __addsf3 is not include in my rtems. but this symbol is linked by libgcc.a<br>

Yes that will work but it means we may still have a bug and we should attempt to resolve this.<span class=""><font color="#888888"><br>

Hello,<br>
<br>
I develop some application using RTL library. But I have follow error.<br>
<br>
·path : /ram:0/app_task module load fail : 22(global symbol not found:<br>
__addsf3)<br>
<br>
·path : /ram:0/app_task module load fail : 22(global symbol not found:<br>
__floatsisf)<br>

·My base rtems does not include library that include __addsf3,<br>
__floatsisf, but also I think my application does not include that.<br>

These functions are found in libgcc.a.<br>

·I use follow command for compile and linking for application.<br>

Hmm I wonder if this is related to Peng patch he posted on the devel list the other day ...<br>

It might be worth a try. I am yet to comment on this patch.<br>

I use rtems 4.10 with leon3(sparc archecture).<br>
<br>
Why does not include __addsf3 and __floatsisf libraries in application?<br>
How can I include that functions in my application?<br>
<br>

<br>
The rtems-ld should manage this. I suspect the options to gcc and the rtems-ld are not lining up.<br>
