Re: cross-compiling question: static libraries and binaries to different places?

 this is needed for win32 compiles atleast, and I have a
 patch on my disk which generalizes the idea for all
 cross-gcc targets (since there have been problems with
 crosscompiling linux-to-linux). 

You mean this?

I just spent two hours realizing why libtool could not link with shared
libraries when cross-compiling; it ended up being exactly the thing
you're talking about.  I created a patch according to your suggestion
on the libtool mailing list, and it makes life much nicer.

Is this in CVS yet?  By golly, it sure needs to be.

Unbalanced parenths in 'ltdl.m4' emitted to 'configure'

2002-03-07 Thread Grzegorz Jakacki 


Hi,

  $ libtool --version
  ltmain.sh (GNU libtool) 1.4.2 (1.922.2.53 2001/09/11 03:18:52)

The macro from 'ltdl.m4' emitted by Autoconf to my 'configure' causes
syntax error

  ~/mypackage $ ./configure
  ./configure: syntax error at line 434: `)' unexpected

My 'configure' looks like:

 424: # serial 2 AC_LIB_LTDL
 425:
 426: # AC_LIB_LTDL
 427: # ---
 428: # Perform all the checks necessary for compilation of the ltdl objects
 429: #  -- including compiler checks and header checks.
 430: # AC_LIB_LTDL
 431:
 432: # AC_LTDL_ENABLE_INSTALL
 433: # --
434: ])# AC_LTDL_ENABLE_INSTALL
 435:
 436: # AC_LTDL_SYS_DLOPEN_DEPLIBS
 437: # --
 438: # AC_LTDL_SYS_DLOPEN_DEPLIBS

I traced this down to 'ltdl.m4':

 60: # AC_LTDL_ENABLE_INSTALL
 61: # --
 62: AC_DEFUN(AC_LTDL_ENABLE_INSTALL,
 63: [AC_ARG_ENABLE(ltdl-install,
 64: [  --enable-ltdl-install   install libltdl])
 65:
 66: AM_CONDITIONAL(INSTALL_LTDL, test x${enable_ltdl_install-no} != xno)
 67: AM_CONDITIONAL(CONVENIENCE_LTDL, test x${enable_ltdl_convenience-no} != xno)
68: ])])# AC_LTDL_ENABLE_INSTALL

With parentheses on ltdl.m4:68 unbalanced in the whole 'ltdl.m4' (to be
precise: it balances the '(' inserted on the first line if I remove all
case ... esac).

The parentheses are still unbalanced in the revision 1.39.

Regards
Grzegorz

PS: Plese CC me, I am not on the list.
