Visual Studio 无法识别 Makefile 项目中的 GCC 链接器错误 [英] Visual Studio doesn't recognize GCC linker Errors in Makefile Project

问题描述

我们有一个交叉编译的 Visual Studio Makefile 项目.我们已经不得不引入一个 与此类似的解决方案 让它识别编译器错误.IE.我们引入了一个 Perl 脚本来解析 GCC 的输出并将其转换为 Visual Studio 可以理解的形式.如果我们声明:

We have a cross compiled visual studio Makefile project. We have already had to introduce a solution similar to this to get it to recognize compiler errors. Ie. We have introduced a Perl script to parse the output from GCC and convert it into a form that Visual studio will understand. If we declare:

int succ = thisRandomFunction(userPointer, 1, 1);

如果没有对 thisRandomFunction 的定义，我们就会得到链接器错误:

with no definition for thisRandomFunction then we will get the linker error:

1>  ./program.a(taskqueue.o): In function `TaskQueueAdd': 1> 
D:\Git\program\taskqueue.c(94,1) : undefined reference to `thisRandomFunction' 1>  
collect2: ld returned 1 exit status 1>  make: *** [program.exe] Error 1

但 Visual Studio 实际上并未将其识别为错误.具有相同问题的 Visual Studio C++ 控制台程序出现链接器错误:

But visual studio doesn't actually recognize this as an error. A Visual Studio C++ console program with the same problem has the linker error:

1>  TestUndefinedReference.cpp
1>TestUndefinedReference.obj : error LNK2019: unresolved external symbol "int __cdecl something(int)" (?something@@YAHH@Z) referenced in function _main
1>D:\Projects\New folder\TestUndefinedReference\Debug\TestUndefinedReference.exe : fatal error LNK1120: 1 unresolved externals

通过使用这个转换器:

sub parseLinkerError
{
    my $str = $_[0];
    my $find = "undefined reference to";
    my $replace = "error LNK2019: unresolved external symbol";
    $str =~ s/$find/$replace/g;
    return $str
} 

我们可以转换这个:

1>  d:\Git\program/taskqueue.c:94: undefined reference to `thisRandomFunction'

进入这个

1>  D:/Git/eV+/program/taskqueue.c(94,1) error LNK2019: unresolved external symbol `thisRandomFunction'

但这还不足以欺骗 Visual Studio 链接器错误解释器.看到链接器错误的最低要求是什么?是否有任何解决方案可以在不直接解析文本的情况下工作?

But this isnt enough to trick the visual studio linker error interpreter. What are the minimum requirements for it to see a linker error? Are there any solutions that can work without directly parsing the text?

推荐答案

根据 文档...

输出格式应为:

{filename (line# [, column#]) | toolname} : 
[any text] {error | warning} code####: localizable string 

地点:

• {a |b} 是 a 或 b 的选择.
• [ccc] 是一个可选的字符串或参数.

例如:

C:\sourcefile.cpp(134) : error C2143: syntax error : missing ';' before '}'
LINK : fatal error LNK1104: cannot open file 'somelib.lib'

<小时>您的示例失败，因为它缺少必需的冒号

---

Your sample fails because it's missing a required colon

D:/Git/eV+/program/taskqueue.c(94,1) error LNK2019: unresolved external symbol `thisRandomFunction'
                                    ^
