linker-errors

问题 Anyone have idea on this? Linker errors are way out of my wheelhouse, especially ones like this. Is there any more info I should include? 1>Linking... 1>freeglut_static.lib(freeglut_window.obj) : warning LNK4075: ignoring '/EDITANDCONTINUE' due to '/OPT:ICF' specification 1>LIBCMTD.lib(dbgheap.obj) : error LNK2005: __heap_alloc already defined in LIBCMT.lib(malloc.obj) 1>LIBCMTD.lib(dbgheap.obj) : error LNK2005: __recalloc already defined in LIBCMT.lib(recalloc.obj) 1>LIBCMTD.lib(dbgheap.obj)

问题 I am trying to compile my project with an open source library GDCM on Visual C++ 2010 on Windows 7 64 bits. I have included required .lib files (gdcmDSED.lib and gdcmMSFF.lib) in my project, however, the compiler complains back more than 100 unresolved external errors. But I see some patterns in the errors. Here: 1>gdcmDSED.lib(gdcmSequenceOfItems.obj) : warning LNK4049: locally defined symbol ??1?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QAE@XZ (public: __thiscall std:

问题 I'm trying to do another exercise from Deitel's book. The program calculates the monthly interest and prints the new balances for each of the savers. As the exercise is part of the chapter related to dynamic memory, I'm using "new" and "delete" operators. For some reason, I get these two errors: LNK2019: unresolved external symbol WinMain@16 referenced in function ___tmainCRTStartup fatal error LNK1120: 1 unresolved externals Here is class header file. //SavingsAccount.h //Header file for

问题 I'm having trouble linking a shared library using gcc 3.2.3 with binutils 2.18. When I try to link the library I get the following error: .gnu.linkonce.t_... referenced in section .rodata: defined in discarded section .gnu.linkonce.t... I've done a fair amount of googling on this and most places seem to indicate it is a regression introduce in binutils 2.17 and later fixed in 2.18.50, but I was curious if anybody knew if there were any particular workarounds for the issue without having to

问题 I'm writing in C++ under XCode 4.6 on Mountain Lion. I'm trying to add and use the Apache log4cxx library. I installed the library this morning via Brew. I'm linking against liblog4cxx.dylib. I'm getting a link error that just one symbol can't be found: Undefined symbols for architecture x86_64: "log4cxx::Logger::forcedLog(log4cxx::helpers::ObjectPtrT const&, std::__1::basic_string, std::__1::allocator > const&, log4cxx::spi::LocationInfo const&) const", referenced from: I know it's finding

问题 I'm trying to create a program (C++) that can read multiple file formats, on Windows (VS2015). In order to do that, I created a solution with a Project for MyProgram (which is the main program), and a project for MyLibrary (which contains several parser for different file formats). In MyProgram I create some parser objects based on the program input. Everything was working well. However, I tried to create a new file format parser (NiftiParser) that uses an external library, nifticlib, that I
