Bug#1060832: RM: graph-tool [ppc64el] -- ROM; Does not build on ppc64el

[Jerome BENOIT]

Hi,

I have just tried to build the graph-tool package on the platti porter box
(ppc64el arch porter box) once with the option -mlong-double-128 and once
with the option-mlong-double-80 . The two attempts failed.

Accordingly I second the request made by Andreas.

Best,
Jerome

I wonder if you are seeing the effects of a 128-bit long double. If it
is, then -mlong-double-80 may help. I've had to use -mlong-double-80
in the past with some GNU software because it lacked support for
128-bit floats.

The companion option is -mlong-double-128. Also see
.

Hi,

the latest version of graph-tool did not build on ppc64el[1].
There is the following error in the log:


/usr/include/boost/math/tools/promotion.hpp:267:27: error: static assertion 
failed: Sorry, but this platform does not have sufficient long double support 
for the special functions to be reliably implemented.
  267 |  static_assert((0 == std::is_same::value), 
"Sorry, but this platform does not have sufficient long double support for the 
special functions to be reliably implemented.");
  |~~~^~

It seems the latest boost is doing some check that can not be fulfilled
on ppc64el.  Thus I think it is best to remove the binary package for
ppc64el for the moment to enable the testing migration of graph-tool
(and completing the boost transition by doing so).

Kind regards
   Andreas.
