I’m trying to reduce the build time, hence, I’m experimenting with ccache. It works fine on ubuntu and decreases build time from about 40 min to less than 10 min. However, on Windows (MinGW), it says: ccache: error: execv of /C/tools/msys64/mingw64/bin/g++.exe failed: No such file or directory. T…

You can check Windows builder snapshot 1809 to see what is preinstalled (as well as environment and registry) in a Windows image without having to run a build every time.

Ccache is not preinstalled in Windows so it’s up to you to install and set it up if you need it.

Yes, I know. I have installed it using pacman (mingw-w64-x86_64-ccache). The problem is not that ccache is not installed or not found. The problem is, that ccache cannot execute g++, although it seems to have the correct file path /C/tools/msys64/mingw64/bin/g++.exe

okay, fair enough, I’ve asked that question. The more interesting question is, however: how can I make it work? I’ve installed ccache, and cmake finds it. Still i get this error and i have no idea where it comes from, how to debug or how to resolve it. No related issues in the internet. Now I’m a…

Hello, I’m starting out slowly on a similar adventure. My take was on using the “official” build of ccache for windows now that one is available, as in https://github.com/networkupstools/nut/blob/master/.travis.yml#L931 and prefixes “ccache” expicitly into “CC” or “CXX” definition as in https://git…

thanks for your reply. I have now abandoned ccache entirely and build my project with multiple cores to meet the 50-minute time limit. I had to switch from make to ninja, because make does not support parallel build on MinGW, apparently. So my solution is not to use ccache. That’s sad, but maybe…

I’m sorry, but I can’t do your job for you (or rather, I can, but not for free) and it’s your job to diagnose problems in 3rd-party software. I would start from checking that all files exist, and what kind of files they are (e.g. Cygwin emulates symlinks as files with special content), then using P…

No one asked you personally to help me or to do my job. The docs advised me to ask my question in the forum, hence, if you’re paid by travis, I think it actually is your and your colleagues’ job to help me out. If you’re a volunteer, I’d kindly thank you very much for your time and help :blush:. I…

[image] pasbi: make does not support parallel build on MinGW, apparently. That’s news to me. I’ve been getting by perfectly well with -j $(nproc) to make.

That was the answer to your question: “Is ccache supposed to work?” — “It’s up to you to make it work.”
