Have spent a couple of days trying to build around 800 ports with gcc5.
This one has me stumped!
Can anyone help regarding the apparant absence of snprintf from std? Am I
missing something, perhaps LDCONFIG or? I've looked in /usr/ports/Mk/
bsd.gcc.mk and /usr/ports/Mk/bsd.port.mk but this is an area that I'm
unfamiliar, so nothing really stood out.
If I change the compiler from gcc5 to clang everything compiles and runs
correctly. I have in /etc/make.conf
USE_GCC= 5
and to use clang, I just comment out the above. So everything is constant,
on FreeBSD 10.3Stable (updated and rebuilt overnight)
For example: /usr/ports/devel/jsoncpp (but many share this problem)
g++5 -o buildscons/linux-gcc-FreeBSD/src/lib_json/json_reader.o -c -O2
-pipe -DOPENSSL_NO_SSL2 -DOPENSSL_NO_SSL3 -g0 -ggdb0 -DSTRIP_FBSDID
-UDEBUGGING -UDEBUG -march=c3-2 -mtune=c3-2 -Wl,-rpath=/usr/local/lib/gcc5
-fno-strict-aliasing --std=c++11 -Wl,-rpath=/usr/local/lib/gcc5 -Iinclude
src/lib_json/json_reader.cpp
src/lib_json/json_reader.cpp: In member function 'std::__cxx11::string
Json::Reader::getLocationLineAndColumn(Json::Reader::Location) const':
src/lib_json/json_reader.cpp:34:18: error: 'snprintf' is not a member of
'std'
#define snprintf std::snprintf
And for completeness:
# ldconfig -r | grep -E "gcc|\+"
