xorg-server-legacy @1.20.10_1 does not build on Tiger because of missing posix_spawn support.

Leopard has /usr/include/spawn.h and /usr/include/sys/spawn.h, Tiger would need /opt/local/include/LegacySupport/sys/spawn.h…

This will be shown (or just tried?) next!

Main.log from PPC Tiger

[ballapete (Peter "Pete" Dyballa)]

It already has:

      6 PortGroup       legacysupport 1.1

Is this a bit too much? Is it faulty to use -isystem/opt/local/include/LegacySupport? It's presumingly not enough, not correct, bundle_trampoline.c should include <sys/spawn.h>… Is Legacy Support just missing the C header file that includes <sys/spawn.h>?

[ballapete (Peter "Pete" Dyballa)]

bundle_trampoline.c needs one data data type and three functions defined:

    posix_spawnattr_t
    posix_spawnattr_init()
    posix_spawnattr_setflags()
    posix_spawn()

Leopard has them in /usr/include/sys/spawn.h.

I got this one.

Yes, xorg-server-legacy now uses posix spawn. The plan is for me to add these functions to legacysupport, which is 99% done, rather than conditionalize xorg-server-legacy.

For now, Tiger users must use xorg-server-1.18 which still uses the old Tiger-compatable method of launching the server.
