c++ - 当我尝试在 Qt 上构建项目时出现错误 "error: CL/cl.h: No such file or directory"

Question

我正在尝试通过 Qt Creator 在我的系统上运行“Valar”基准测试应用程序，但在构建代码时出现错误:

https://github.com/Frinhard/valar-bench

我输入命令:autoreconf -ivf 并得到以下输出:

autoreconf: Entering directory `.'
autoreconf: configure.ac: not using Gettext
autoreconf: running: aclocal --force -I m4
aclocal: couldn't open directory `m4': No such file or directory
autoreconf: aclocal failed with exit status: 1

我所有的错误都与文件 m4 有关，所以我创建了一个空目录并将其命名为 m4。之后，我能够运行命令 autoreconf --install 并且我不再不断收到相同的错误。此外，还生成了 Makefile.in 以及许多其他文件。

该链接显示了我运行 autoreconf --install 后目录的状态:

我在命令行上运行命令 qmake --project 并生成了 .pro 文件。

我在 Qt Creator 中打开了新生成的 .pro 文件，并链接了 OpenCL 库以及“bin”目录中的其他 OpenCL 文件。

以下是我掌握的关于qmake的资料:

Qmake version: 1.07a (Qt 3.3.8b)
Qmake is free software from Trolltech ASA.

请在这件事上指导我。

当我更改设置路径的方法后，问题得到解决。

在我的问题中，我按以下方式设置了路径:

LIBS += -L$$PWD/../../usr/local/cuda-7.0/lib64/ -lOpenCL

INCLUDEPATH += $$PWD/../../usr/local/cuda-7.0/lib64 $$PWD/../../usr/local/cuda-7.0/include
DEPENDPATH += $$PWD/../../usr/local/cuda-7.0/lib64

我按照以下方式再次设置路径，错误得到修复:

LIBS += -L/usr/local/cuda-7.0/lib64/ -lOpenCL

INCLUDEPATH += /usr/local/cuda-7.0/lib64/\
               /usr/local/cuda-7.0/include/

我还从我在 .pro 文件中设置的其他路径中删除了 $$PWD/../.. 部分。

进行这些更改后，我的代码开始正常运行。
