Ccache warning
in [Ports]
|
From: Denny Lin on 5 Jun 2010 01:24 Hi, I saw this warning about devel/ccache a while ago: Any time you change CC/CXX you need to reinstall devel/libtool15 or you will run in to problems. This was added a long time ago, so I'm wondering if this is still necessary (should be devel/libtool22 now). -- Denny Lin _______________________________________________ freebsd-ports(a)freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscribe(a)freebsd.org"

If that's true it should be added to http://www.freebsd.org/doc/en_US.ISO8859-1/articles/custom-gcc/index.html. Can anyone comment authoritatively?

I've been using ccache for years without bothering about this. The only problems are caused by ports that cannot deal with spaces in CC/CXX (~2% of my installed ports). -- A: Because it fouls the order in which people normally read text.

If you look at the output of 'libtool --config', you will see that libtool sets default values for the compiler, toolchain, various flags, and library search directories, that can change depending upon what compiler and tool-chain are used to build libtool. Depending upon how libtool is called, it may fall back upon default values, or override some of them. Since not all ports call libtool in a clean and uniform way, it may be better to have a different copy of libtool for each compiler and tool-chain that you intend to use, that has been configured and built with that compiler and tool-chain, and then to use that version of libtool for ports built with that compiler and tool-chain, by altering the definition of some of the libtool-related variables in ports/Mk/bsd.autotools.mk to depend conditionally upon CC. This is one of the components of the port system that is ill-suited in it's current configuration for using different compilers and toolchains. There are others: qmake4, cmake, etc. -- unfortunately, a lot of ports depend upon these. b. _______________________________________________ freebsd-ports(a)freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscribe(a)freebsd.org"
