Statically linking against library built with different version of C Runtime Library, ok or bad?

由 时光总嘲笑我的痴心妄想 提交于 2019-12-21 09:18:15
问题 Consider this scenario: An application links to 3rd party library A. A is built using MSVC 2008 and is statically linking (ie. built with /MT) to the C Runtime Library v9.0. The application is built using MSVC 2005 and is statically linking to A and (using /MT) to the C Runtime Library v8.0. I can see trouble with this - for instance if types are changed in the headers between runtime library versions. Is care taken to keep the runtime library headers compatible between versions, or should

Thread creation, the CRT and DLL's how is it meant to be done?

由 别说谁变了你拦得住时间么 提交于 2019-12-21 02:47:27
问题 So I understand that CreateThread and the CRT can result in memory leaks, signal doesn't work, and one should use the _beginthread or _beginthreadex functions. That is all very well when writing an application, but what about those that are writing dll's and such for other applications (be it a plain c dll, com objects, plugins, etc). There is no way to guarantee how a thread calling into a DLL was created, even if they used __beginthread(ex) its a pretty likely bet they have a different CRT

问题 I'm back with C/C++ and ASM and I want to play a little bit with fire. I found out that when you compile and link code into an executable for Windows it is dynamically linked to some libraries that must exists on any computer where that application is expected to run. You can specify the compiler to not link against them and create your own libraries for that. Apart from that (and please, correct me if I'm wrong in everything I say here) there's an object file that is always complied and

问题 With Visual Studio 2015 I am no longer able to compile and link a simple C++ program using the command line tools. Consider main.cpp: #include <stdlib.h> int main() { return 0; } In previous releases (for example Visual Studio 2012) I was able to compile and link main.cpp easily: C:\Users\bkircher\src\test>cl main.cpp Microsoft (R) C/C++ Optimizing Compiler Version 17.00.61030 for x64 Copyright (C) Microsoft Corporation.

问题 I'm using Visual Studio c++ Compiler ( 2010 ), but the library has different implementation of ANSI C and POSIX libraries function. What is the difference between ANSI C function and Windows CRT implementation? For example what is the difference between tzset() and _tzset() or setenv() ans _setenv() ? It seems the do the same thing in the same way... I'm using msvc ( 2010 ), have I to prefer the Windows CRT Implementation? EDIT 1 Well I want convert in a portable way a struct tm expressed in

C++ - Memory leak testing with _CrtDumpMemoryLeaks() - Does not output line numbers

由 江枫思渺然 提交于 2019-12-17 19:18:09
问题 I'm working on a game with SDL in Visual Studio 2010. I came across the _CrtDumpMemoryLeaks() macro and thought I'd give it a go. Invoking _CrtDumpMemoryLeaks() does print memory leaks to the output window, but it does not show where it happens. I've read the MSDN article at Memory Leak Detection Enabling , and it explains that if I define _CRTDBG_MAP_ALLOC it should output the line number of the offending statement. This does not happen in my case. (I was however able to get it to work if I

How to use .key and .crt file in java that generated by openssl?

问题 I need asymmetric encryption in java. I generate .key and .crt files with own password and .crt file by openssl that said in http://www.imacat.idv.tw/tech/sslcerts.html . How to use these .key and .crt file to extract publickey and private key in Java? 回答1: Your .key and .crt files may be in PEM format. To check this open them with a text editor and check whether the content looks like ------BEGIN CERTIFICATE------ (or "begin RSA private key"...). This is generally the default format used by

Should I link to the Visual Studio C runtime statically or dynamically?

由 给你一囗甜甜゛ 提交于 2019-12-17 08:32:19
问题 I have read arguments on both sides about whether one should link to the C runtime library statically or dynamically in Visual Studio projects, and I'm still not entirely sure what to think. My project pulls in some third-party libraries (Python, HDF5, Trilinos, and Microsoft MPI), each of which has to be built with the same runtime library as my final executable (otherwise they cannot be linked together). When linking statically, each of these libraries will contain a copy of the C runtime.
