Re: rt-thread problem

[bernard]

Hi Esko, 

Since RT-Thread 1.2.x, we have moved it from googlecode to github.com:

https://github.com/RT-Thread/rt-thread

In there, you can use English to report issue etc. 

For you mentioned issue, you can refer the travis-ci compiling result to see how to compile mini2440 with GCC:

https://travis-ci.org/RT-Thread/rt-thread

Hello,

I write to you directly, because rt-thread forum is in chinese.
Firstval, you have done great work with the rt-thread. Thanks! I hope,
you could have time to translate user guide to english. I am now
trying to compile and link rt-thread with gnu arm eclipse tools. I
took head trunk from googlecode. Many of bsp:s compile and lind
without problem, like stm32f107, but there is also many which won't
work, like mini2440, which I would like to run in qemu.

Build of mini2440 ends up following error

es\gui\demo_view_bmp.o build\examples\gui\demo_plot.o

scons: *** [rtthread-mini2440.axf] Error 1

Could you give some advice which is wrong?
