I'm not sure if this is the correct forum, but as this is related to the development of the ApolloOS kernel...

Someone is looking at contributing to the ApolloOS project, but they want to use a Windows environment to do it. They've setup NASM and MinGW (moving the binaries to the C:\Windows directory) and I've worked with them to provide a batch file that should actually work... (I'm not sure how we'll go about mounting the floppy image to add the kernel executable, I assume that may need a third-party app)

However, we're coming across a bit of a problem. Each time he runs it he gets:

Code: Select all

gcc: installation problem, cannot exec 'cc1' : No such file or directory

for each C file that we try to compile (of which there are 8 ). Then the inevitable 'kernel.o not available' error when it comes to linking.

There seems to be nothing wrong with the batch file (code included below). Have we done something wrong during the installation?

Code: Select all

@echo off
echo Now assembling, compiling, and linking your kernel:

I tend to use a Linux environment to develop ApolloOS, so this is a new one on me.

Ok, not to worry - I think I've cracked it.

Thanks to Mike Saunders for his suggestion. After a bit of research I realised that we need to alter the PATH variable for MinGW. Essentially Step 3 of this tutorial:

It just goes to show - do your homework about a package before you install it

(though I tend to use a Linux distro to develop ApolloOS so I think I can be forgiven for an oversight there! )
