Hi,
I'm trying to compite boostpythongenerator-0.3 under windows (with MinGW,
gcc 3.4.5). I get an error ("error ISO C++ forbids casting between
pointer-to-function and pointer-to-object") on line 124 of the file
main.cpp. The line in questions is included in the code section below :
122 if (!generatorSet.isEmpty()) {
123 QLibrary plugin(generatorSet+"_generator");
124 getGeneratorsFunc getGenerators =
reinterpret_cast<getGeneratorsFunc>(plugin.resolve("getGenerators"));
125 if (getGenerators)
126 generators = getGenerators();
127 else {
128 std::cerr << argv[0] << ": Error loading generatorset plugin:
" << qPrintable(plugin.errorString()) << std::endl;
129 return EXIT_FAILURE;
130 }
131 }
I'm not sure what to do about it. QLibrary::resolve does return a void*
which the code try to cast to a function pointer (i.e.getGeneratorsFunc is
defined by "typedef QLinkedList<Generator*> (*getGeneratorsFunc)();") ans
this does seem not to be a portable line of code (you may read the
discussion on
http://www.velocityreviews.com/forums/t288899-reinterpret-cast-problem.html
).
Any idea?
