According to those instructions, for distcc use you only need cctools and a compiler. You don't need any headers as the code distcc sends to servers is preprocessed on the client.

This seems to be working, I download for my OSX the correct gcc, run on my Mac gcc -v and get the target, that I copy the /Developer/SDKs directory, that I would use, to the Linux box and run this commands mkdir darwin cd darwin ../gcc_42-5577/configure --prefix=/opt/osxtoolchain/snowleopard/ --enable-languages=c,c++ --target=i686-apple-darwin10 --with-sysroot=/opt/osxtoolchain/snowleopard/MacOSX10.6.sdk/ make configure runs, but the make creates an error: # APPLE LOCAL use -mlongcall for large text support /root/darwin/./gcc/xgcc -B/root/darwin/./gcc/ -B/opt/osxtoolchain/snowleopard//i686-apple-darwin10/bin/ -B/opt/osxtoolchain/snowleopard//i686-apple-darwin10/lib/ -isystem /opt/osxtoolchain/snowleopard//i686-apple-darwin10/include -isystem /opt/osxtoolchain/snowleopard//i686-apple-darwin10/sys-include -O2 -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -I. -I. -I../../gcc_42-5577/gcc -I../../gcc_42-5577/gcc/. -I../../gcc_42-5577/gcc/../include -I../../gcc_42-5577/gcc/../libcpp/include -I../../gcc_42-5577/gcc/../libdecnumber -I../libdecnumber -mlongcall \ -fno-tree-dominator-opts \ \ -c ../../gcc_42-5577/gcc/config/darwin-crt3.c -o crt3.o rch: invalid option -- 'f' rch: invalid option -- 'o' rch: invalid option -- 'r' rch: invalid option -- 'c' rch: invalid option -- 'e' rch: invalid option -- '_' rch: invalid option -- 'c' rch: invalid option -- 'p' rch: invalid option -- 'u' rch: invalid option -- 's' rch: invalid option -- 'u' rch: invalid option -- 'b' rch: invalid option -- 't' rch: invalid option -- 'y' rch: invalid option -- 'p' rch: invalid option -- 'e' rch: invalid option -- '_' rch: invalid option -- 'A' rch: invalid option -- 'o' rch: rch: Unrecognized architecture make[4]: *** [crt3.o] Error 1 make[4]: Leaving directory `/root/darwin/gcc' make[3]: *** [extra] Error 2 make[3]: Leaving directory `/root/darwin/gcc' make[2]: *** [stmp-multilib] Error 2 make[2]: Leaving directory `/root/darwin/gcc' make[1]: *** [all-gcc] Error 2 make[1]: Leaving directory `/root/darwin' make: *** [all] Error 2 Do you have any idea to solve the problem?

[gentoo-user] distcc cross-compiling for OSX
Hello, I have installed distccd on my Gentoo box and I would like to use it from a OSX Snow Leopard. The distcc daemon runs on the Gentoo box and my OSX clients connect the box. I can run distcc on my OSX and it send the code to the Gentoo box and compile it. But my cross-compiling does not work at the moment: distcc[6233] ERROR: compile mytest.cpp on gentoo failed distcc[6233] (dcc_build_somewhere) Warning: remote compilation of 'mytest.cpp' failed, retrying locally I have checked the content of the directory /usr/lib/distcc/bin there are only the local compiler calls: lrwxrwxrwx 1 root root 15 Sep 27 11:17 c++ - /usr/bin/distcc lrwxrwxrwx 1 root root 15 Sep 27 11:17 cc - /usr/bin/distcc lrwxrwxrwx 1 root root 15 Sep 27 11:17 g++ - /usr/bin/distcc lrwxrwxrwx 1 root root 15 Sep 27 11:17 gcc - /usr/bin/distcc lrwxrwxrwx 1 root root 15 Sep 27 11:17 x86_64-pc-linux-gnu-c++ - /usr/bin/distcc lrwxrwxrwx 1 root root 15 Sep 27 11:17 x86_64-pc-linux-gnu-g++ - /usr/bin/distcc lrwxrwxrwx 1 root root 15 Sep 27 11:17 x86_64-pc-linux-gnu-gcc - /usr/bin/distcc I think I must add a OSX specified symbolic link. Which tools / configuration must be set for cross-compiling OSX code on my Gentoo box? Thanks Phil
Re: [gentoo-user] distcc cross-compiling for OSX
I think I must add a OSX specified symbolic link. Symlinks are only needed on the distcc client, not on the server running distccd. But that is a trivial matter. Which tools / configuration must be set for cross-compiling OSX code on my Gentoo box? You need to put together a complete OSX cross toolchain. This basically means building cctools (osx's equivalent of binutils) and apple's compiler from source. Then you have to do some additional plumbing on both ends to get it all to work. An overview of the process for 10.4: http://myownlittleworld.com/miscellaneous/computers/darwin-cross-distcc.html Do note that quite a lot of things have changed from back then, so those instructions are probably not going to work. andrea
