Hi folks, I'm trying to get the forthcoming groff release building on the geriatric Solaris 10, something that worked as recently as July 2023.
I ran into the following problem.
In file included from ./src/include/driver.h:25:0,
from src/devices/grodvi/dvi.cpp:25:
./lib/math.h: In function ‘bool signbit(float)’:
./lib/math.h:3281:1: error: ‘bool signbit(float)’ conflicts with a previous
declaration
_GL_MATH_CXX_REAL_FLOATING_DECL_2 (signbit, signbit, bool)
^
In file included from
/opt/csw/lib/gcc/sparc-sun-solaris2.10/5.5.0/include-fixed/math.h:23:0,
from ./lib/math.h:46,
from ./src/include/driver.h:25,
from src/devices/grodvi/dvi.cpp:25:
/usr/include/iso/math_c99.h:688:14: note: previous declaration ‘bool
std::signbit(float)’
inline bool signbit(float __X) { return __builtin_signbitf(__X); }
Inspecting src/devices/grodvi/dvi.cpp, I saw that it had:
#ifdef HAVE_CONFIG_H
#include <config.h>
#endif
...but further checking revealed that src/include/driver.h did not.
However, adding it didn't solve the problem.
What can I do to overcome this?
Please reply to both lists; I'm not subscribed to bug-gnulib.
Regards,
Branden
