zsh 4.2.5 compile problem on AIX

zsh 4.2.5 compile problem on AIX

[David Favor]

I've built many version of zsh for AIX including 4.2.0
which I'm currently running. This appears to be a new
problem.

Building zsh-4.2.5 on AIX 5100-08 the following shows up:

    gmake[2]: Entering directory `/data/build/work/zsh-4.2.5/Src/Zle'
    rm -f complete.so
    xlc_r -s -bM:SRE -o complete.so -bI:zle.export -bI:../../Src/zsh.export \
       -bE:complete.export -emodentry complete..o compcore..o compmatch..o \
       compresult..o  ../../Src/modentry..o  -L/usr/local/lib -lpcre -liconv \
       -ldl -lcurses -lm  -lc
    ld: 0711-317 ERROR: Undefined symbol: nullstrsetfn
    ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
    gmake[2]: *** [complete.so] Error 8
    gmake[2]: Leaving directory `/data/build/work/zsh-4.2.5/Src/Zle'
    gmake[1]: *** [modules] Error 1
    gmake[1]: Leaving directory `/data/build/work/zsh-4.2.5/Src'
    gmake: *** [modules] Error 2

The problem appears to be nullstrsetfn being located in params.o
and having no reference to params.o anywhere on link line. There
is an entry for nullstrsetfn in ../../Src/zsh.export so perhaps
this is where the nullstrsetfn reference is meant to be satisfied.

Suggestions about how to fix this?

Thanks.

Thanks for spotting this:  there is a perennial problem with AIX which is
particularly finnicky about the declaration of symbols used in a library.
There's a script Util/check_exports which I should run before making a
release.  Here's a fix for 4.2; I'll commit the change for 4.3 directly.
