All the failures are due to a single error: > In file included from /usr/include/c++/4.8/cmath:44:0, > from /usr/include/c++/4.8/random:38, > from /usr/include/c++/4.8/bits/stl_algo.h:65, > from /usr/include/c++/4.8/algorithm:62, > from location.hh:41, > from input.hh:90, > from input.cc:50: > /home/isd/kramer/temp/bison-3.4.2/lib/math.h: In function 'bool > isnan(double)': > /home/isd/kramer/temp/bison-3.4.2/lib/math.h:2849:1: error: new declaration > 'bool isnan(double)' > _GL_MATH_CXX_REAL_FLOATING_DECL_2 (isnan, isnan, bool) > ^ > In file included from /usr/include/features.h:374:0, > from > /usr/include/x86_64-linux-gnu/c++/4.8/bits/os_defines.h:39, > from > /usr/include/x86_64-linux-gnu/c++/4.8/bits/c++config.h:426, > from /usr/include/c++/4.8/cstdlib:41, > from input.hh:48, > from input.cc:50: > /usr/include/x86_64-linux-gnu/bits/mathcalls.h:234:1: error: ambiguates old > declaration 'int isnan(double)' > __MATHDECL_1 (int,isnan,, (_Mdouble_ __value)) __attribute__ ((__const__)); > ^ so this is "only" a portability issue of our test suite, it's not a problem in Bison itself. Thanks a logs, but actually the file testsuite.log in tests/ contains more information, including config.log which we need to understand why lib/math was installed, and why it wants to install a "better" isnan. Could you please send testsuite.log or config.log? Thanks in advance!
