[ECOS] FW: GCC 3.4.3 on ARM7TDMI problem

[msteinme]

Hi,

I have seen several people that are successfully using GCC 3.4.3 on
ARM7TDMI.  I am wondering how they resolved the "unrecognized command
line option -finit-priority" problem that kills my build of ECOS.   I
had been using gcc 3.2.1 but appear to be having problems with the 3.2.1
gcc generating some bogus code when making a call to a function via a
pointer contained in a structure. 

Thanks,

Mark Steinmetz

The latest tree (from anonymous CVS) does not allow this option.

Are you using the CVS tree?

I have gcc 3.4.3 from gnuarm.net --- I downloaded the binaries.

For ECOS, I am likely out of date since I have been using a book by
Anthony Massa (and associated software) as my "ECOS FOR DUMMIES".

I will get the latest tree.

Thanks!

[ECOS] Floating point Hardware/emulation for ARM7TDMI

[msteinme]

 Hi,

I am using gcc 3.4.3 from gnuarm.net,  and the latest ECOS tree,  and am
having a problem when I execute the MAKE for my "hello world" project.

I get an error showing the libtarget.a uses hardware FP whereas basic1
uses software FP.

I can find nowhere in the eCOS configuration to specify use of the
software FP when building the libtarget.a during the ECOS build.

Can anyone provide some insight on this.
