Package: libime
Version: 1.0.13-1
Severity: important
Tags: hppa, patch
libmime fails to build on the hppa (PA-RISC) architecture because of
the check in ./test/testtrie.cpp:
auto nan1 = std::nanf("1");
...
// NaN != NaN, we must use memcmp to do this.
FCITX_ASSERT(memcmp(&nan1, &result, sizeof(float)) == 0);
This is basically the same problem as reported for the mips platform:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=973576
The problem is, that hppa and (older) mips use a different encoding for NaNs
than
all other platforms. See: https://en.wikipedia.org/wiki/NaN
The attached patch is from John David Anglin <dave.ang...@bell.net>
and fixed the problem for hppa.
I assume that if the:
#ifdef __hppa__
is changed to
#if defined(__hppa__) || (defined(__mips__) && !defined(__LP64__))
then it probably fixes the debian bug report 973576 as well.
Thanks,
Helge
