在VS2010中编译失败的C ++程序在Linux中可以正常工作 [英] Compilation fails in VS2010 for C++ programs building fine in Linux

问题描述

我的C ++项目在Linux上构建和运行良好。现在我正试图在VS2010中编译它。

 错误1错误C2061：语法错误：标识符'acosf'c ：\ program files \microsoft visual studio 10.0 \vc\include\cmath 19 1 MyPROJ 
  

<

 错误1错误C3861：'lseek'：标识符未找到g ：\project\file.cc 274 1 MyPROJ 
 
错误2错误C3861：'写入'：标识符未找到g：\​​project\file.cc 275 1 MyPROJ 
  

如何消除这些错误。

解决方案

div>

lseek和write是不是C标准的一部分的unix（posix？）调用。
它们在窗口中可用，但使用名称_lseek和_write

虽然不确定acosf

编辑：acosf应该可用，你包括math.h

编辑更多：仔细查看原始帖子错误是在cmath这是罚款，虽然然后你可能必须写std :: acosf - 但是错误在include文件中。当我尝试它时，它的工作正常，所以包含之前的某些内容可能会发生冲突。在您的来源中包含cmath之前是什么？

My C++ project builds and runs fine on Linux. Now I am trying to compile it in VS2010. I get many errors seemingly from cmath library like the following one.

Error   1   error C2061: syntax error : identifier 'acosf'  c:\program files\microsoft visual studio 10.0\vc\include\cmath  19  1   MyPROJ

Also I get many file operations related compilation errors like:

Error   1   error C3861: 'lseek': identifier not found  g:\project\file.cc  274 1   MyPROJ

Error   2   error C3861: 'write': identifier not found  g:\project\file.cc  275 1   MyPROJ

How to eliminate these errors.

解决方案

lseek and write are unix (posix?) calls that are not part of the C standard. They are available on windows but using the names _lseek and _write

not sure about acosf though

EDIT: acosf should be available, are you include math.h

Edit more: Looking more closely at the original post the error is in cmath which is fine although then you probably have to write std::acosf - but the error is in the include file. It works fine when I try it so something before the include is likely conflicting. What is before the include of cmath in your source?
