哪个库包含_is_c_termination_complete

Question

通过将LNK2019代码链接到标准库C++库，我得到了C++错误。我需要知道哪些库包含以下功能：

• is_c_termination_complete，
• __acrt_initialize，
• __acrt_uninitialize，
• __acrt_uninitialize_critical，
• __acrt_thread_attach，
• __acrt_thread_detach

将其包含在链接过程中。

我正在用MSVisualStudioCommunity2017和英特尔并行工作室xe 2019更新1编写C++代码，以便集成到第三方软件中。第三方软件提供了一个"make“选项来编译对象文件并将它们链接到一起。

编译工作良好，链接提供了一个问题。

第三方软件提供一个条目，以变量的形式提供基本的链接器选项。默认选项如下：

link_sl='LINK', '/nologo', '/NOENTRY', '/INCREMENTAL:NO', '/subsystem:console', '/machine:AMD64', 
' /NODEFAULTLIB:LIBC.LIB', '/NODEFAULTLIB:LIBCMT.LIB','/DEFAULTLIB:OLDNAMES.LIB', '/DEFAULTLIB:LIBIFCOREMD.LIB', '/DEFAULTLIB:LIBIFPORTMD.LIB', '/DEFAULTLIB:LIBMMD.LIB', '/DEFAULTLIB:kernel32.lib', '/DEFAULTLIB:user32.lib', '/DEFAULTLIB:advapi32.lib','/FIXED:NO', '/dll','/def:%E', '/out:%U', '%F', '%A', '%L', '%B', 
'oldnames.lib', 'user32.lib', 'ws2_32.lib', 'netapi32.lib','advapi32.lib', 
'msvcrt.lib', 'vcruntime.lib', 'ucrt.lib']

这将在链接时产生以下11个错误：

msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __vcrt_initialize referenced in function __scrt_initialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __vcrt_uninitialize referenced in function __scrt_initialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __vcrt_uninitialize_critical referenced in function __scrt_dllmain_uninitialize_critical
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __vcrt_thread_attach referenced in function __scrt_dllmain_crt_thread_attach
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __vcrt_thread_detach referenced in function __scrt_dllmain_crt_thread_attach
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol _is_c_termination_complete referenced in function __scrt_dllmain_uninitialize_c
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_initialize referenced in function __scrt_initialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_uninitialize referenced in function __scrt_uninitialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_uninitialize_critical referenced in function __scrt_dllmain_uninitialize_critical
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_thread_attach referenced in function __scrt_dllmain_crt_thread_attach
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_thread_detach referenced in function __scrt_dllmain_crt_thread_detach

这基本上意味着我没有包括所有必要的图书馆。我已经发现，在选项中包含库'libvcruntime.lib‘可以将错误减少到6。

link_sl='LINK', '/nologo', '/NOENTRY', '/INCREMENTAL:NO', '/subsystem:console', '/machine:AMD64', 
' /NODEFAULTLIB:LIBC.LIB', '/NODEFAULTLIB:LIBCMT.LIB','/DEFAULTLIB:OLDNAMES.LIB', '/DEFAULTLIB:LIBIFCOREMD.LIB', '/DEFAULTLIB:LIBIFPORTMD.LIB', '/DEFAULTLIB:LIBMMD.LIB', '/DEFAULTLIB:kernel32.lib', '/DEFAULTLIB:user32.lib', '/DEFAULTLIB:advapi32.lib','/FIXED:NO', '/dll','/def:%E', '/out:%U', '%F', '%A', '%L', '%B', 
'oldnames.lib', 'user32.lib', 'ws2_32.lib', 'netapi32.lib','advapi32.lib', 
'msvcrt.lib', 'vcruntime.lib', 'ucrt.lib',**'libvcruntime.lib'**]

在以下方面的成果：

msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol _is_c_termination_complete referenced in function __scrt_dllmain_uninitialize_c
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_initialize referenced in function __scrt_initialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_uninitialize referenced in function __scrt_uninitialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_uninitialize_critical referenced in function __scrt_dllmain_uninitialize_critical
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_thread_attach referenced in function __scrt_dllmain_crt_thread_attach
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_thread_detach referenced in function __scrt_dllmain_crt_thread_detach

为了解决这些问题，我需要在链接过程中包括哪些其他库？

Answer 1

在这个第三方软件提供的框架内工作时，我遇到了完全相同的问题。虽然我无法直接回答查找包含_is_c_termination_complete的库的问题，但我意识到仍然有可能使代码工作:只需将/FORCE标志添加到link_sl标志列表中即可。

根据MSVC正式文件

/FORCE选项告诉链接器创建一个有效的.exe文件或DLL，即使符号被引用，但没有定义，或者是乘法定义的。

因此，LNK2019错误消息不会阻止链接器生成dll库，这对于第三方软件的运行至关重要。链接器消息看起来应该是：

msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol _is_c_termination_complete referenced in function __scrt_dllmain_uninitialize_c
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_initialize referenced in function __scrt_initialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_uninitialize referenced in function __scrt_uninitialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_uninitialize_critical referenced in function __scrt_dllmain_uninitialize_critical
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_thread_attach referenced in function __scrt_dllmain_crt_thread_attach
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_thread_detach referenced in function __scrt_dllmain_crt_thread_detach
 : warning LNK4088: image being generated due to /FORCE option; image may not run
msvcprt.lib(locale0_implib.obj) : warning LNK4210: .CRT section exists; there may be unhandled static initializers or terminators

这当然不是一个体面的解决方案，也不能保证在任何情况下都能工作，但是至少对我的代码是有效的。
