Note Book: OpenCV v4.5.0-dev On Ubuntu 20.04 But Didn't work cmake build for Java
Conclusion
- It's not OpenCV's fault, It's Ubuntu fault.
- If OpenCV with cuda, It's needed gcc and g++ version 8 under.
I found it. But I can't found for Apache Ant. https://bugs.launchpad.net/ubuntu/+source/python3-defaults/+bug/1876957 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1633839
I put it. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1902570
Reason
- Because the Apache Ant symbolic is broken, link installed by apt-get.
- It' working. I use export CC and CXX. ・ Export CC = gcc-8 ・ Export CXX = g ++ -8
Contents I wanna set up something like this against OpenCV 4.5.0-dev, but I can't build it on ubuntu 20.04 LTS. Because the symbolic link in Ant is broken. I'm using the apt-get command to get Apache Ant. But the /bin/ant command does not work. It's a throw ClassNotFoundException.
$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=20.04
DISTRIB_CODENAME=focal
DISTRIB_DESCRIPTION="Ubuntu 20.04.1 LTS"
It's not work, '/bin/ant'.
The symbolic link is a ...?? What's this? /usr/bin/ant -> ../share/ant/bin/ant /bin/ant -> ../share/ant/bin/ant
This '/bin/ant -> ../share/ant/bin/ant' is a '/bin/share/ant/bin/ant'. It's nothing the Path.
I delete /bin/ant, And create new symbolic link. But I think upside down, /bin/share/ant/bin/ant is true. Because /bin/share has a higher priority more than /usr/bin/share.
sudo rm -fr /bin/ant
sudo ln -s /usr/share/ant/bin/ant /bin/ant
What I want to do.
I wanna doing samething liks like this configuration.
