g++ - linker error cannot find symbol name in library -



g++ - linker error cannot find symbol name in library -

g++ (gcc) 4.7.2 3.7.6-201.fc18.x86_64 #1 smp mon feb 4 15:54:08 utc 2013 x86_64 x86_64 x86_64 gnu/linux fedora release 18 (spherical cow)

hello,

i compiling , having problem trying link program.

the linker error is:

/usr/bin/ld: point.o: undefined reference symbol '_znwj@@glibcxx_3.4' /usr/bin/ld: note: '_znwj@@glibcxx_3.4' defined in dso /lib/libstdc++.so.6 seek adding linker command line /lib/libstdc++.so.6: not read symbols: invalid operation collect2: error: ld returned 1 exit status

this object file point.o trying phone call function doesn't exist in libstdc++.

when seek , check if symbol name exist using readelf can't find it.

readelf --all libstdc++.so.6.0.17 | grep _znwj@@glibcxx_3.4

is because point.o looking symbol in older libstdc++ have been removed in later version?

many suggestions,

in case using gcc not g++. used work in '12, later build on different machine in '14 choked. gnu compiler has indeed changed. reply in case add

-lstdc++

onto end of linking line, error messages suggest. hth.

linker g++

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
