Building atlas 21.2 against the blas in hardy, I get:

 Test of subprogram number 10ICAMAX
   FAIL

 CASE  N INCX INCY MODECOMP
TRUE DIFFERENCE

   10  41     3 
  2   1

make: *** [debian/test/xcblat1] Error 1

and when upgrading blas to -proposed, I get a complete build.  copying
to hardy-updates.

[Steve Langasek]

** Description changed:

  Binary package hint: blas
  
  On architectures with internal floating point precision higher than that
  of the varibles (such as 68000, x86) files src/icamax.f and src/izamax.f
  must necessarily be compiled with -ffloat-store option. Otherwise the
  corresponding functions do not perform to their specification and the
  corresponding blas level 1 tests fail. This, in particular, prevents
  atlas-3.6.0-21.1ubuntu2 from building on i386.
  
  It is, of course, an overkill to enable -ffloat-store for the whole
  BLAS, but enabling it only for two said files works well and the impact
  on performance is negligible.
  
  This can be acomplished by the following changes to debian/rules
  BOBJ:=$(BSRC:.f=.o)
  +BOBJ1:=$(filter-out src/izamax.o,$(filter-out src/icamax.o,$(BOBJ)))
  +BOBJ2:=src/icamax.o src/izamax.o
  
  
  
  debian/shared_dir debian/static_dir debian/test_dir:
  mkdir -p $(subst _dir,,$(@))
  touch $@
  
  !$(subst src/,debian/static/,$(BOBJ1)): \
  debian/static/%.o : src/%.f debian/static_dir debian/patch_applied
  
  $(F77) $(F77FLAGS) -c $< -o $@
  
  +$(subst src/,debian/static/,$(BOBJ2)): \
  +debian/static/%.o : src/%.f debian/static_dir +debian/patch_applied
  +
  +$(F77) $(F77FLAGS) -ffloat-store -c $< -o $@
  
  The resulting library passes all of the BLAS test suite. This also fixes
  atlas-3.6.0-21.1ubuntu2 build problem.
+ 
+ TEST CASE:
+ 1) grab the atlas 3.6.0-21.1ubuntu2 source package from 
.
+ 2) try to build it on hardy/i386
+ 3) install the blas packages from hardy-proposed
+ 4) try to build it again

[Steve Beattie]

Would it be possible for someone to add a testcase to the description of
this bug, perhaps in particular describing which blas level 1 tests fail
and how to invoke them? This is one of the bugfixes we'd like to verify
in the SRU BugHug day tomorrow:
https://wiki.ubuntu.com/UbuntuBugDay/20080624

Thanks!

This bug was fixed in the package blas - 1.2-1.6

---
blas (1.2-1.6) unstable; urgency=low

  * Build using the default gcc/gfortran compilers except on alpha.
  * On architectures with internal floating point precision higher than that
of the variables (such as 68000, x86) files src/icamax.f and src/izamax.f
must necessarily be compiled with -ffloat-store option. Otherwise the
corresponding functions do not perform to their specification and the
corresponding blas level 1 tests fail. Don't build the whole library
with -ffloat-store. Suggested by Konstantin L. Metlov in Launchpad.
Closes: #202869. LP: #202869.
  * Fix bashisms in debian/rules. Closes: #484373.

Thanks very much for finding out what went wrong!

Subscribing Matthias: you're the last uploader of blas, can you take a
look at this, please?

Thanks,
