I have been trying to install Codeblock 20.03.  I thought it installed tried to run a simple fortran program when I did build and run I got the following:
-------------- Build file: "no target" in "no project" (compiler: unknown)---------------

g++.exe   -c C:\Users\frank\OneDrive\Desktop\test.f90 -o C:\Users\frank\OneDrive\Desktop\test.o
g++.exe  -o C:\Users\frank\OneDrive\Desktop\test.exe C:\Users\frank\OneDrive\Desktop\test.o   
C:\Users\frank\OneDrive\Desktop\test.o:test.f90:(.text+0x53): undefined reference to `_gfortran_st_write'
C:\Users\frank\OneDrive\Desktop\test.o:test.f90:(.text+0x6c): undefined reference to `_gfortran_transfer_character_write'
C:\Users\frank\OneDrive\Desktop\test.o:test.f90:(.text+0x78): undefined reference to `_gfortran_st_write_done'
I then tried to remove Codeblock and reinstall got into more problems.  How can I uninstall codeblock and remove everything?  Got message need to have adminstrator authorization to remove some.  I am mot sure what I hanging around on my computer now.  Need a method todo a complete removal. I am on a 64 machine where should I be storing the download?  I am lost.

You have also to configure a fortran compiler (anf of course use it in your project), normally gfortran for gnu distribution. Have a look in the codeblocks manual. G++ is normally used for c++ but is also able to compile fortran, but at link time, you need gfortran. See paragraph 5.2.3 in the pdf (or chm documentation file).
