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 miss 19 > 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 cache 40 > cache size 163.8 kB > Any idea ?
