How to apply a gcc patch

Question

I am trying to apply this patch to GCC on MinGW to get it to compile GDC 2 , but I do not know how to do it. (I'm still not familiar with the internal components of GCC and even the * nix tools in general.) I know that there is a patch command, but I can’t figure out how to use it, and I don’t even know, I have enough information for this .

How to apply a patch for GCC?

Answer 1

By default, GNU Patch can be used by loading the patch file into it from stdin (input to the console), for example:

 patch < file.patch 

There are many switches and patch options, the functionality of which is described here:

http://www.gnu.org/software/diffutils/manual/html_mono/diff.html#Invoking%20patch

patch and diff work hand in hand. A small demo is found on wikipedia .

Answer 2

Take a look at the patch manual pages. Just type man patch in the terminal window ... usually I think you want to do patch -p0 -i your_file.diff .
