Dave,
That would explain why I don't get through configure and you guys
do. I get a "error: C++ compiler cannot create executables" error
message.
Cheers
Matt

Thanks. That fixed the cxxtest apps. I'm still somewhat

iperf though as iperf is built using configure. Shouldn't
configure and
ucfront* take care of setting up the linker flags (among other

for me?
You are right it *should* take care of this but it obviously doesn't
for some reason.
I am using the latest uClinux dist and it doesn't even finish the
configure for me?? I guess it was broken at some point.
Hmm, we build iperf here on a daily basis from that source.
Could be the toolchain though, I only think we build it on i386 at
the
moment, there may be fixes in the config.arch that are needed for arm
etc.
Have a look there first if you want to compare,

Thanks,

Hi Lance,
There are some pieces missing from the test c++ apps. Find
attached a
patch. Dave/Gerg would you mind applying this to the tree.
The problem with iperf is that you are not linking against pthread.
I haven't tried building iperf, but I do notice that your link line
does not include pthreads and you will need to add this. Adding
$(SLIBPTHREAD) to your link line should fix the problem.
Cheers

Thanks Matt. With that change I can now build and run some C++

am still seeing a couple issues though (with both the gcc 3.4.4

Do these two apps build correctly for you with the Snapgear
toolchain?
If so what vendor/platform are you using so I can compare the
settings?
