compiling zsh: executable linker flags

compiling zsh: executable linker flags

[Vincent Lefevre]

I'm compiling zsh 4.0.2 under Solaris. I use the following configure
options:

  --prefix=$HOME
  --exec-prefix=$HOME/$ARCHTYPE
  --enable-maildir-support
  --with-curses-terminfo
  --enable-cppflags="-I$HOME/include"
  --enable-ldflags="-L$HOME/$ARCHTYPE/lib"

But at the end, configure says:

zsh configuration
-----------------
zsh version               : 4.0.2
host operating system     : sparc-sun-solaris2.7
source code location      : .

module linker flags       :   -G
library flags             : -lsocket -ldl -lnsl -lcurses -lm  -lc

info install path         : /users/spaces/lefevre/info
functions install path    : /users/spaces/lefevre/share/zsh/4.0.2/functions
See config.modules for installed modules and functions.

Shouldn't the "executable linker flags" line contain the corresponding
-L option like under Linux?

Broken configure? (was: compiling zsh: executable linker flags)

I've added some echo's in configure. Under Solaris:

***** LDFLAGS 12: -L/users/spaces/lefevre/alpha-osf1/lib
checking for working RTLD_GLOBAL... yes
***** LDFLAGS 13: 

This is because of the line

    LDFLAGS=$save_ldflags

Note that "save_ldflags" isn't set before. Something wrong?

The attached patch solves this problem, and zsh now correctly works
under Solaris. But under OSF, I still get the

  zsh: can't find termcap info for rxvt

error. This seems to mean that zsh hasn't been linked to the version
of ncurses I've installed in my $HOME.
