cannot build on OSX/intel with --optimize

[coke]

Build on

$ sw_vers
ProductName:    Mac OS X
ProductVersion: 10.4.11
BuildVersion:   8S2167

with:

perl Configure.pl --optimize --ccflags=-g --prefix=/Users/coke/bird
make -j3

at r41853 (haven't built on this platform in some time, no clue when this failure started)

perl is 5.10.0, gcc version 4.0.1 (Apple Computer, Inc. build 5363)

yields

I think this is an OS X 10.4 issue, because I can compile with --optimize on x86/darwin just fine. Does this still happen when not doing a parallel build, i.e. no -j3 ?

Replying to dukeleto:

Tried with the same compiler options but just a straight 'make' - same build failure.

Tried building without --cflags=-g - same build failure.

failing portion of build.

[coke]

In the output, there is:

ld: common symbols not allowed with MH_DYLIB output format with the -multi_module option

lazyweb tells me that for this to work, we need to add -fno-common to the build. If I don't specify --optimize, that's in the ccflags. If I do specify optimize, it's not.

Looks like -fno-common is in my 10.6.4 OSX/intell build, and I've been building with --optimize for a while on this platform.

Closing ticket.
