Mac OS X: tango.math.IEEE doesn't compile

Most likely since "doubledouble" is the default type of real...

Changing runtime assert into compiletime assert gives: 

tango/math/IEEE.d:1525: static assert  "Unsupported"

commit #3308 should fix this.

Replying to Don Clugston:

commit #3308 should fix this.

Partially, these still remain: 

tango/math/IEEE.d:685: Error: template instance 'floatTraits!(real)' is not a variable
tango/math/IEEE.d:685: Error: no property 'EXPMASK' for type 'int'
tango/math/IEEE.d:700: Error: template instance 'floatTraits!(real)' is not a variable
tango/math/IEEE.d:700: Error: no property 'POW2MANTDIG' for type 'int'
tango/math/IEEE.d:701: Error: template instance 'floatTraits!(real)' is not a variable
tango/math/IEEE.d:701: Error: no property 'EXPPOS_SHORT' for type 'int'

Also got two -w warnings that I patched: 

warning - tango/math/IEEE.d:577: Error: statement is not reachable
warning - tango/math/IEEE.d:686: Error: implicit conversion of expression (cast(int)((cast(short*)(& x))[4u]) & 32767) of type int to short can cause loss of data

  • attachment tango-ieee-warnings.patch added.

02/28/08 09:18:59 changed by Don Clugston

  • status changed from new to assigned.

I've stopped the warnings, but the line numbers in the error messages don't make sense.

02/28/08 09:37:17 changed by afb

line numbers might have been from a hacked version, sorry about that. (should have referred to the same lines that was in the patch though)

02/28/08 11:38:32 changed by Don Clugston

I didn't use the patch. The code I submitted compiles on DMD-Win when triggered by the static assert -- are you sure there wasn't a bug in the patch? Because that code should n't be triggered on Mac OS X. real.mant_dig != 64 on MacOSX.

02/28/08 17:55:47 changed by afb

  • status changed from assigned to closed.
  • resolution set to fixed.

Seems to build fine now, maybe I was mistaken
