Re: [Yade-dev] Make ccache working
I checked your ubuntu 12.04 page again. That's actually about hiding ccache behind normal gcc invocation, and I kind-of dislike the idea. Explicit call to «ccache g++» sounds cleaner to me and it is compatible with mpicxx (for ubuntu 16.04 at least). Better undo what you have done until now in terms of ccache hacks and stick to yade doc's method if you are unsure. «ccache -s» also reports unsupported options on my ubuntu 16.04 but a full rebuild takes 40sec regardless.

Re: [Yade-dev] Make ccache working
Also, did you start from fresh build after exporting CXX? I mean: rm -rf ./* export ... cmake [options] make -jN Bruno Le mer. 27 mars. 2019 18:33, Bruno Chareyre a écrit : > Hi François, > > Please remember to give your linux version. > > On Wed, 27 Mar 2019 at 17:44, François wrote: > >> export CXX=ccache g++ >> >>> bash: export: « g++ » : identifiant non valable >>> >> Using >> >>> export CXX='ccache g++' >> >> works >> > > Thanks for pointing that out.

[Yade-dev] Make ccache working
Hi all, I'm trying to use ccache but I have two issues. - the first one is the "installation" with the "export" command that doesn"t work: export CXX=ccache g++ > bash: export: « g++ » : identifiant non valable > Using > export CXX='ccache g++' works but it will result in cmake fail while checking cc compiler. Finally, I "installed" ccache thanks to the first answer here: https://askubuntu.com/questions/470545/how-do-i-set-up-ccache and it *kinda* works. - the second one, once the install is ok and cmake uses ccache, is that I only get "unsupported compiler option" when I try *ccache -s* after a full yade compilation. It results in a almost-empty cache: *cmake:* -- Check for working C compiler: /usr/lib/ccache/cc > -- Check for working C compiler: /usr/lib/ccache/cc -- works > -- Detecting C compiler ABI info > -- Detecting C compiler ABI info - done > -- Detecting C compile features > -- Detecting C compile features - done > -- Check for working CXX compiler: /usr/lib/ccache/c++ > -- Check for working CXX compiler: /usr/lib/ccache/c++ -- works > *ccache -s:* > cache directory /home/francois/.ccache > primary config /home/francois/.ccache/ccache.conf > secondary config (readonly)/etc/ccache.conf > stats zero time Wed Mar 27 16:25:15 2019 > cache hit (direct) 1 > cache hit (preprocessed) 0 > cache miss19 > cache hit rate 5.00 % > called for link 34 > called for preprocessing 12 > preprocessor error 1 > unsupported compiler option *195* > no input file 2 > cleanups performed 0 > files in cache40 > cache size 163.8 kB > Any idea ?

Re: [Yade-dev] Some update on futur steps
Hi,
For people interested in helping for python 3, the branch is here:
https://gitlab.com/yade-dev/trunk/tree/python-3
Look at the readme for infos about dev.
Cheers,
François
