Small correction – for success resolving name by clinet extern “C” must be as on export side as on import. extern “C” will reduce name of proc to: “_GetName”. More over you can force any name with help of section EXPORTS in .def file
objdump -C The -C flag enables demangling: printf ‘ template<typename T> T add(T x, T y) { return x + y; } void h() { add(1, 2); add(1.0, 2.0); } ‘ > a.cpp g++ -g -std=c++11 a.cpp objdump -CS a.out The output contains demangled names: int main() { add(1, 2); 60c: e8 28 00 00 … Read more
The standard does not address implementation details. There are many, many things which depend on the implementation, and which prevent programs from working together: how the classes are laid out, the structure of the vtable, etc. In general, compilers will change the name mangling if they change any of these. This is intentional, as it … Read more
You can, with some caveats. You either have to use the member function in a way that code will be generated or have it be not inline, and your mangled definition should be extern “C” to prevent “double mangling”. E.g.: #include <cstdio> struct Foo { const char* message; void goo(); }; void Foo::goo() { std::printf(“%s”, … Read more
The pedantically correct way to check that a .so exports a symbol is nm –demangle –dynamic –defined-only –extern-only <lib.so> | grep <symbol>. Without –defined-only your command also shows undefined symbols. Without –extern-only it also shows symbols with internal linkage which are unavailable for linking. It looks like you need to link another library because Gps_Ephemeris::Gps_Ephermeris() … Read more
You can use c++filt to demangle c++ symbols. For instance $ c++filt -n _Z1fv f()
You can simply use g++ to compile an empty function with the signature you require and extract the name from that. For example: echo “int f1(char *, int) {} ” | g++ -x c++ -S – -o- | grep “^_.*:$” | sed -e ‘s/:$//’ gives output _Z2f1Pci which is I think what you require. Make … Read more
There is an easier way to invoke method reflectively without resorting to calling Java reflection methods: use Structural Typing. Just cast the object reference to a Structural Type which has the necessary method signature then call the method: no reflection necessary (of course, Scala is doing reflection underneath but we don’t need to do it). … Read more
Use nm to see all symbols and c++filt to demangle. Example: nm -an foo | c++filt
In the programming language of your choice, if an identifier is exported from a separately compiled unit, it needs a name by which it is known at link time. Name mangling solves the problem of overloaded identifiers in programming languages. (An identifier is “overloaded” if the same name is used in more than one context … Read more
