[MANI18]

Hi everyone!

I have recently downloaded the source file and a third-party file from the website https://develop.openfoam.com/Develop...r/doc/Build.md.

I followed the installation procedure provided on the website, but encountered an error. The error message is as follows:


========================================

It appears that the compiler is unable to locate the file "Instant.h" for some unknown reason.

I am seeking assistance and guidance in resolving this issue. Any help or advice would be greatly appreciated.

Looks like you might have initially aborted when building the include files links. If you haven'd gotten very far, you can simply use a wclean -all from the top level.


That is a bit drastic, so normally I would just rebuild the links if needed.Eg,

# Change to the OpenFOAM directory (with the 'foam' alias)

$  foam 



# Rebuild the links

$  wmakeLnInclude -u -pwd src/OpenFOAM

The '-u' option is for update. I always the '-pwd' option, which resolves based on the Make/files. For example,

$  wmakeLnInclude -u -pwd src/OpenFOAM


# Same thing...

$  wmakeLnInclude -u -pwd src/OpenFOAM/containers

The reason for the '-pwd' would be this:

$  foam


$  cd src/OpenFOAM/containers


# edit something, create some files,....



# later

$  wmakeLnInclude -u -pwd

Works even if you are deeper down somewhere within the tree.

Thank you for your comprehensive response concerning this error. The issue was caused by my use of 7-Zip on Windows to extract the file, which resulted in the loss of some files during the installation process. However, I have resolved the problem by unzipping the folder using the command


"tar -xvf filename.tar.gz".
