- j 6 buildworld: -lcapsicum use before libcapsicum.so.0 /usr/obj/usr/src/tmp/lib/ install

[Mark Millard]

This is a -j 6 buildworld context.

In the following sequence the -lcapsicum use when linking libcasper.so.0.full does not use /usr/obj/usr/src/tmp/lib/libcapsicum.so because that file and the link to it at /usr/obj/usr/src/tmp/usr/lib/libcapsicum.so are only created (installed) later. (See the sequence later below.)

This can lead to use of /lib/libcapsicum.so instead if it is found, which for my context it is. In my case of updating from 11.0-CURRENT from back on 2015-Apr-18 /lib/libcapsicum.so use ends up complaining about undefined references, such as to nvlist_getf_binary that existed back then but do not now. That is what exposed the time-order problem.

The -L's ending with /.'s are from my /etc/src.conf . They are associated with trying to self-build on a powerpc64 PowerMac using only powerpc64-xtoolchain-gcc's powerpc64-gcc WITH_LIBCPLUSPLUS: powerpc64-gcc is acting as both the host toolchain and the CROSS_TOOLCHAIN. No 4.2.1 gcc is present. I know this is not a usual way of doing things. There may be better ways. But if I manage to expose some missing dependency tracking some good came of it.

The make command was:

> make -j 6 WITH_FAST_DEPEND= CROSS_TOOLCHAIN=powerpc64-gcc WITH_LIBCPLUSPLUS= WITHOUT_CLANG_BOOTSTRAP= WITH_CLANG= WITH_CLANG_IS_CC= WITH_LLDB= WITHOUT_GCC_BOOTSTRAP= WITHOUT_GCC= WITHOUT_GNUCXX= WITHOUT_BOOT= WITHOUT_LIB32= buildworld buildkernel KERNCONF=GENERIC64vtsc-NODEBUG TARGET=powerpc TARGET_ARCH=powerpc64


Context details if you care:

I am attempting an update after having been away from the PowerMacs for months.
