Hi
I am now reading the manual pages for src.conf.=20
Src.conf should only be used to specify variables for make, e.g. WITHOUT_PR=
OFILE, or WITH_CCACHE_BUILD. Man src.conf does not say much more about ccac=
he, but ccache-howto-freebsd says that WITH_CCACHE_BUILD is only for buildi=
ng ports with ccache; for world and kernel you should set CC and CXX variab=
les within make.conf following the advice in ccache-howto=20
("To use ccache for ports, just add WITH_CCACHE_BUILD=3Dyes to /etc/make.co=
nf.
To use ccache for base add the following to /etc/make.conf:
.if (!empty(.CURDIR:M/usr/src*) || !empty(.CURDIR:M/usr/obj*))
.if !defined(NOCCACHE) && exists(/usr/local/libexec/ccache/world/cc)
CC:=3D${CC...
....
")
I do not copy here the full howto
My problem is that after a successful compile of base - world and kernel - =
using ccache I run make installkernel correctly, but after reboot and merge=
master -p I got a lot of ccache error messages during make installworld. Th=
ey complain ebout not finding compiler cc in path although cc -v gives the =
clang version number, so cc IS on the path.
Best regards
Andr=E1s Krasznai

Oops, I should have looked into man src.conf before asking here, sorry.
And many thanks for the quick and helpful answer.
