[mad-dev] madplayer cross-compile on ARM11 compilation error "impossible constraint in 'asm'"

[Jianfeng Li]

Hi, All,
 
I am now trying to cross-compile the madplayer on an arm11 based embedded system.  The compiler I am using is from montavista mobilinux 5.0.
 
When I tried to build the madplay, for the file resample.c, I got 2 errors on line 89 and 104.  The error information is "impossible constraint in 'asm'.  When I tried to build the libmad, I also met the same error.  But it seems that during compilation if "FPM-ARM" option is enabled then the error is solved.  But here I checked the Makefile, there is no such option of "FPM" as in the Makefile of libmad.  
 
So can anybody help to tell me why this error happens, it is due to the compiler's constraint/requirement?  How should I try to solve this error?  Is "trying to enable the FPM" a good option to try?
 
Many thanks in advance!
 
Regards,
Jeffen
