the ccache program works perfectly for me. on a machine first compile something it add its work to the cache and the second time a compile the same source it takes the objects from the cache what speed up the compilation time. prima job but now i have other machine and want to have also the speed up in the network setup so if i compile a source on a machine the first time it at his work to the cache that is for every pc the same nfs shared map. ( man ccache SHARING A CACHE is ok) an if i compile the source on a other machine than it takes the object form the network shared cache, but thats my problem a simple hello_world.c program works fine, this say that i have configured the ccache good. but it doesnt work correctly with complexer program's , and like you say al the headers, compilers options, etc etc i dont know all the parameters, must be the same, or there is no hit for it . my question is, how can i let say set a DEBUG_OPTION flag to see all these options and see thats ccache saying there is header.h or gcc-options-x that is not the same like in the ccache files i must recompile this. of course i can make a copie of the disk from my first pc to the second pc this weekend change the ip an go on that must be good, but if i later have installed something newer on the one and not on the other pc than i have the problem again and it should be easy perhaps to backtrace it with toggling a debug option or so in ccache. now i go working but i do a emerge world because it is a gentoo distro to be sure it al the tools are in sync. i hope you understand my problem ? > > Try > > ls -l /usr/bin/gcc > > or whatever compiler name is appropriate. > > Do you have *exactly* the same headers on both machines?
