![未找到包“opencv4”](https://linux22.com/image/954943/%E6%9C%AA%E6%89%BE%E5%88%B0%E5%8C%85%E2%80%9Copencv4%E2%80%9D.png)
我的 makefile 中有这一行:
$(CLINAME): $(LIBNAME) main.c
$(CC) -o $@ main.c -std=c99 `pkg-config --cflags --libs opencv4` -Iinclude -L. -l$@ -lm
我正在尝试运行我的代码,但是当我写下以下内容时出现此错误:
Package opencv4 was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv4.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv4' found
请问该如何修复?
答案1
OpenCV 可从 Ubuntu“universe”存储库获得 - 除非您需要与发行版打包的版本不同的版本,否则我建议您通过apt
而不是从第三方安装它。发展元包被命名libopencv-dev
,并且它的当前版本是
软件包 libopencv-dev
focal (20.04LTS) (libdevel): development files for opencv [universe] 4.2.0+dfsg-5: amd64 arm64 armhf ppc64el riscv64 s390x jammy (22.04LTS) (libdevel): development files for opencv [universe] 4.5.4+dfsg-9ubuntu4: amd64 arm64 armhf ppc64el riscv64 s390x lunar (23.04) (libdevel): development files for opencv [universe] 4.6.0+dfsg-11: amd64 arm64 armhf ppc64el riscv64 s390x mantic (23.10) (libdevel): development files for opencv [universe] 4.6.0+dfsg-13build1: amd64 arm64 armhf ppc64el riscv64 s390x noble (libdevel): development files for opencv [universe] 4.6.0+dfsg-13build5: amd64 arm64 armhf ppc64el riscv64 s390x
安装libopencv-dev
还将安装依赖的运行时库1和支持opencv4.pc
文件pkg-config
。
- 我不确定它是否能安装全部OpenCV 组件或只是核心组件,你需要解析输出以
apt depends libopencv-dev
确保
