I am trying to program a few simple apps in C++ under Mandrake Linux using the gcc3.2 compiler. Everything works except the new operator. How can I get it working?>

Well, did you say char *str first?

yes, the error is that the new operator is "not defined"

Compile with g++ rather than gcc.

krumms, that would only be a problem if A) his setup does not recognize standard C++ file extensions as C++ files, or, B) he is not using a standard C++ file extension. Modern versions of gcc recognize that a .cpp or .cc or .cxx, etc. files are C++ files, and should compile and link accordingly.

Of course, you should definately at least try this first, and that might tell you what the problem is.

Do you mean something like this:

/tmp/ccyZ2uXU.o(.text+0x16): In function `main'':: undefined reference to `operator new[](unsigned)''/tmp/ccyZ2uXU.o(.text+0x2d): In function `main'':: undefined reference to `operator delete[](void*)''/tmp/ccyZ2uXU.o(.eh_frame+0x11): undefined reference to `__gxx_personality_v0'' 

If so, krumms is right. Use g++ and not gcc. Gcc will invoke g++ to compile your code, but it won''t link with the C++ library. Either use g++ or explicitly link with libstdc++:

g++ -o progname source.cc

or

gcc -o progname source.cc -lstdc++


If it doesn''t help, try to provide more informations, like the exact error message.

Hope this helps.
