Why there is no response for my app on uclinux

I think if it did not run you would get an error stating that it was not an executable or something like that?

What kind of output does it normally have?

I want to port a C++ program to uclinux. But I can&#39;t find a way to compile it using the toolchain under linux.

Could you suggest a clue?

The libstdc++, which I built with buildroot, still has problem to run.

Microtronix sell a linux toolchain with C++ support .

yeah, it seems NIOS2 IDE has stdlibc++, I compile it and use elf2flt to convert it to flat format. but it couldn&#39;t work. Sometimes it tell me reloc outside, sometimes no response. So I get confuse. Maybe CDK from Microtronix could help.

thx for your clue.

So there is no perfect way (of course for free-fee) to make a C++ toolchain,

is it?

By the way, does elf2flt -r means to run with out load?

I&#39;m confuse about the parameters in elf2flt.

And someone said elf2flt just strips the symbol and debug info from elf and make the header simple, is that right?

1. the libstdc++ in IDE is for newlib, it can not run in uClinux.

2. the elf2flt needs several steps, and there are some variation between arch.

for nios2, you should use -elf2flt flag for linkage.

it is difficult to use elf2flt and flthdr alone.

3. it is possible to work out c++ with buildroot. The c++ is compiled and linked, but crashed after c++ func calls. ( I am not a c++ user, I can&#39;t fix the problem. ) .

the tools from Microtronix costs $900, but I think it should be based on buildroot and should be GPL?
