Hi all,
I'm trying to cross-compile iperf for an Opensource Netgear based device
and am running into some problems..
If the software I compile for this Netgear device has the __cx_atexit
function linked to the libc, then the binary doesn't run and gives me
the error:
"can't resolve symbol '__cxa_atexit'".
I can't disable UCLIBC_DYNAMIC_ATEXIT=y in the uClibc as it breaks other
parts of the firmware for which I have no info on how they were
initially built.
I had a similar issue with tcpdump and I convinced it to compile without
the __cxa_atexit by slightly modifying the resulting config.h.
Now with Iperf I've put it to compile for mips, to use my mips-uclibc
compiler, I've even checked the Makefile and saw that HAVE_ATEXIT is
undefined now (tried also to define it = 0 with no luck/changes).
Still, the resulting binary reports like this:
$ nm src/iperf | grep exit
U __cxa_atexit
0040f470 T atexit
U exit
U pthread_exit
0040efe0 T sig_exit
normally it should not have the __cxa_atexit reported.
config.h:
$ cat config.h | grep EXIT
/* #undef HAVE_ATEXIT */
Is there any way for me to convince iperf to obey the flags and compile
without the cxa_atexit libc stuff ?
P.S: Using gcc/g++ 4.2.3, uClibc-0.9.28
Can you help me out ?
Thanks,
Mihai
