RTEMS for MIPS

[Ren, Han Tao (Hans)]

Thomas

Thank you for your message.

Yes, I've installed the BSP to opt/rtems/mips-rtems/.

Let me give more details on what I did.
Actually, I got different toolchains, one is "sparc-rtems", one is
"mips-rtems".
I download the binaries of  "sparc-rtems" on http://www.gaisler.com, but I
had 
to build toolchains for mips-rtems myself, so I download binutils and gcc
source 
code, as well as the patch files for RTEMS.  Then I followed the
instructions in 
the document "Getting Started with RTEMS for C/C++ Users(4.6.0pre4)" to do 
the building, it passed finally and I got the binaries,  but it seemed
mips-rtems-gcc 
refused to work.  However,  the sparc-rtems toolchains are working fine.
The following 
are some log messages.

[root at localhost samples]# mips-rtems-gcc -g -O2 hello.c -o hello
/opt/rtems/lib/gcc-lib/mips-rtems/3.2.2/../../../../mips-rtems/bin/ld:

[root at localhost samples]# sparc-rtems-gcc -g -O2 -rtems rtems-hello.c -o
rtems-hello
[root at localhost samples]# 

I've tried on both Redhat and Solaris platform, the results are same.

Thanks

Hans

Hello,

this is just a guess: Maybe you forgot to "install" the BSP 
you have built. Normally, after configuring and building the 
BSP, it sould be installed with

make install

this will copy the relevant files to a path like 

/opt/rtems/mips-rtems/<bsp>/*

Whenever you try to build an application, the compiler 
normally tries to find the include files and libraries in that 
path...

And, naturally, Ralf is right, the command line switch "-
qrtems" should be visible on the compiler command line. So 
maybe you simply misstyped your command line and the switch "-
rtems" should in fact be "-qrtems"?
wkr,
	Thomas.
