Here is my environment:

distcc 3.1

I'm trying to install on leopard, but I keep getting the following error when running make:

This one is a tricky three-way incompatibility between MacOS gcc, Python, and distcc. MacOS gcc extends gcc with support for multiple -arch options; Python uses them; and distcc invokes gcc via Python, hence picking up the "-arch" options; but MacOS gcc doesn't support the standard gcc "-MD" option when multiple "-arch" options are used.

The work-around is to comment out the "-MD" from the Makefile.

please add -MF xxx.d after -MD CFLAG, you maybe need to modify the makefile,

for example, if you compile use gcc src.c -MD -o ../out/src.o

try this,

gcc src.c -MD -MF ../out/src.d -o ../out/src.o

In makefile, you may need change the rules, like -MD -MF $(patsubst %.o,%.d,$@)

How does adding "-MF xxx.d" help?

I didn't think it would help, but I just tried it, and I still get

bash$ make ... gcc -Wl,-F. -bundle -undefined dynamic_lookup -arch i386 -arch ppc -g -O2 -MD -MF include-server.d ... gcc-4.0: -E, -S, -save-temps and -M options are not allowed with multiple -arch flags

If we can't figure out a perfect solution for this issue, why not directly remove "-MD" flag when it detects it's using MacOS gcc? Or is it better to remove multiple "-arch" since I guess it's less necessary in this case?
