Re: [Lynx-dev] lynx not working on new Mac

[Nelson H. F. Beebe]

Here is what I see on PowerPC and Intel-based Mac OS X systems:

        % file $B/lynx
        /usr/local/bin/lynx: Mach-O executable ppc

        % file $B/lynx
        /usr/local/bin/lynx: Mach-O executable i386

It is possible to build fat binaries on either system that will run on
both, though build attempts that way seem to fail for most packages.

Here are Makefile assignments that I use for such builds:

        CC      = "cc -arch ppc -arch ppc64 -arch i386 -arch x86_64"
        CXX     = "c++ -arch ppc -arch ppc64 -arch i386 -arch x86_64"
        LDFLAGS = -L/usr/local/lib64
        libdir  = /usr/local/lib64

I just tried such a build of lynx2-8-7 on Mac OS X 10.7.5 (Intel),
which has the clang-based /usr/bin/cc; it failed, apparently because
of the lack of cross-platform code generation.

GNU autoconf-generated configure scripts seem to choke on the
fat-binary settings, so on an older PowerPC Mac OS X 10.5.8 system, 
I tried this workaround:

        % env CC=cc ./configure

        % make CC="cc -arch ppc -arch ppc64 -arch i386 -arch x86_64"

        % file lynx
        lynx: Mach-O universal binary with 4 architectures
        lynx (for architecture ppc7400):        Mach-O executable ppc
        lynx (for architecture ppc64):  Mach-O 64-bit executable ppc64
        lynx (for architecture i386):   Mach-O executable i386
        lynx (for architecture x86_64): Mach-O 64-bit executable x86_64

        ./lynx --version
        Lynx Version 2.8.7rel.2 (21 Jun 2010)
        libwww-FM 2.14, ncurses 5.5.20051010
        Built on darwin9.8.0 Feb  6 2013 14:59:30

Success!  [I tested the executable on the Intel-based Mac, and got
identical output.]

If someone is interested in a private distribution of that build,
please contact me directly off list.
