Could Not Create Dir at /home/pi/tmp_cv3

[twenty4k]

New to PI/coding and your tutorial seem to be the best written and most comprehensive for beginners.

However, I am running into this issue:

Could Not Create Dir at /home/pi/tmp_cv3 │
│ Check permissions │
│ If on a mounted Device make sure │
│ 1- Device is mounted and is NOT FAT32 │
│ 2- Device Must be writeable by Pi user. │
│ Check ownership and permissions │
│ │
│ Exit to Terminal to Investigate

Here is the code

./cv3-install-menu.sh: line 122: $LOG_FILE: ambiguous redirect
STEP 2 Install opencv 4.1.2 Build Dependencies

This step will install opencv 4.1.2 Build Dependencies
Then Download and unzip opencv source files to /home/pi/tmp_cv3 Folder

Filesystem Size Used Avail Use% Mounted on
udev 1.6G 0 1.6G 0% /dev
tmpfs 380M 1.4M 378M 1% /run
/dev/mmcblk0p2 29G 4.8G 23G 18% /
tmpfs 1.9G 26M 1.9G 2% /dev/shm
tmpfs 5.0M 20K 5.0M 1% /run/lock
/dev/mmcblk0p1 510M 73M 438M 15% /boot/firmware
tmpfs 380M 44K 380M 1% /run/user/1000

---------------- STEP 2 INSTRUCTIONS ---------------
A Fresh Build Needs at Least 16GB SD with 5-6 GB Free. Free Space
could be less depending on what dependencies are already installed
If you are using a smaller system SD or are Low on Free Disk Space.
You can mount USB media and change variable INSTALL_DIR in this script.
Installs Will Take a While so be Patient ...

Install Dep and Source? (y/n)? y

Thanks for responding so quickly. I think there was an issue with the OS I was using. I reflashed my RPI and reinstalled your program. Works great! I'm a tinkerer and new to RPI and programming. Appreciate your thorough walkthrough. I am having an issue with the program not capturing images of vehicles moving faster than 25mph. I'm using RPI 4 and Camera Module 3 Standard Lens. Would the wide angle lens be better for this application? My setup is probably 50ft from the road. Thanks! Semper FI Michael
