我有蜜蜂试图让assimp在QT 5.2中运行,以便导入一些3D对象,但是林先生(我相信)链接器有问题。

我通过cmake安装了它,首先从此处http://sourceforge.net/projects/assimp/files/assimp-3.0/下载源文件,然后使用cmake进行编译和安装。

然后,我尝试运行它们在文档中提供的示例

#include <assimp/cimport.h>        // Plain-C interface
#include <assimp/scene.h>          // Output data structure
#include <assimp/postprocess.h>    // Post processing flags

bool DoTheImportThing( const char* pFile)
{
  // Start the import on the given file with some example postprocessing
  // Usually - if speed is not the most important aspect for you - you'll t
  // probably to request more postprocessing than we do in this example.
  const aiScene* scene = aiImportFile( pFile,
                                      aiProcess_CalcTangentSpace       |
                                      aiProcess_Triangulate            |
                                      aiProcess_JoinIdenticalVertices  |
                                      aiProcess_SortByPType);
  // If the import failed, report it
  if( !scene)
  {
   // DoTheErrorLogging( aiGetErrorString());
    return false;
  }


  return true;
}


但是当尝试编译这段代码时,我得到了错误

 error: undefined reference to `aiImportFile'
 error: collect2: error: ld returned 1 exit status


我正在使用32位Linux Mint。有人知道为什么不链接吗?我应该使用特定标志使用cmake进行编译吗?我无法在周围的任何帖子中找到任何特殊标志。

谢谢!

最佳答案

我终于解决了!显然,QT具有导入外部库的工具。我只需要右键单击该项目,单击添加库,然后添加位于/user/local/libassimp.a的文件

这将以下行添加到我的.pro文件中:

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../../../../../usr/local/lib/release/ -lassimp
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../../../../../usr/local/lib/debug/ -lassimp
else:unix: LIBS += -L$$PWD/../../../../../usr/local/lib/ -lassimp

INCLUDEPATH += $$PWD/../../../../../usr/local/include
DEPENDPATH += $$PWD/../../../../../usr/local/include

win32-g++:CONFIG(release, debug|release): PRE_TARGETDEPS += $$PWD/../../../../../usr/local/lib/release/libassimp.a
else:win32-g++:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$PWD/../../../../../usr/local/lib/debug/libassimp.a
else:win32:!win32-g++:CONFIG(release, debug|release): PRE_TARGETDEPS += $$PWD/../../../../../usr/local/lib/release/assimp.lib
else:win32:!win32-g++:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$PWD/../../../../../usr/local/lib/debug/assimp.lib
else:unix: PRE_TARGETDEPS += $$PWD/../../../../../usr/local/lib/libassimp.a


可能有一种更优雅的编码方式,但至少它能起作用。
