I am looking at using ccache with this compiler but it is annoyingly unlike gcc :-(. Here are some key differences which makes it incompatible with ccache as it stands. 1. It doesn't support -E for preprocessing. Instead it uses -ppo. 2. When it preprocesses (using -ppo) it doesn't output to stdout as gcc does but instead outputs to a .pp file. By default this is in the current directory (or somewhere else if you use the --pp_directory option as well) 3. ccache assumes that the output file is named with the -o option. The TI compiler uses -fe for this purpose. I had a go at writing a wrapper which could sit between ccache and the TI compiler doing the relevant option conversion but had to shelve this due to particular issues unique to my environment (including backward compatibility with a complex make system; all sorts of issues with quoting and escaping of command line options, some of which contained spaces; and difficulty getting the preprocessed output to stdout). These issues are all probably solvable given enough time but I think that modifying ccache itself is probably a much better solution. > > -Original Message- > From: martinpool gmail.com [mailto:martinpool gmail.com] On Behalf Of Martin Pool > Sent: Friday, November 18, 2011 11:48 AM > To: Zhou, Yang > Cc: ccache lists.samba.org > Subject: Re: [ccache] How to support another compiler? > > On 18 November 2011 14:34, Zhou, Yang polycom.com> wrote: > > Hi all, > > > > I want to use ccache to optimize the compilation of my project.

How are you getting on with this? Is there any way I can help move this forward and avoid duplication of effort? p. ___ ccache mailing list ccache@lists.samba.org https://lists.samba.org/mailman/listinfo/ccache

Hi, Yang Zhou, If you get this working, or even just a start towards it, please post the patch here and hopefully we can integrate it to help others.

Probably you will want to introduce an object layer that describes different compilers, and an environment variable to switch between them.

[ccache] How to support another compiler?
Hi all, I want to use ccache to optimize the compilation of my project. However, another compiler(not gcc) is used for the compilation. The compiler options are different from those of gcc. But I think the compilation process should be similar. I tried to compile with ccache, from the log, every time the manifest file can't be found, and can't find the object file in manifest. After that, preprocessor runs, and got object file hash from preprocessor, but the object file is not in cache. So the real compiler runs every time. Seems the results of real compilation are not stored into the cache. Do you think it's possible to change ccache source code to support the my compiler? If possible, which part of code should be updated? Thanks a lot! Best Regards, Yang ___ ccache mailing list ccache@lists.samba.org https://lists.samba.org/mailman/listinfo/ccache
