Title: CB autotools build system crash with libtool version 2.2.6
Post by: libfab on November 23, 2008, 06:52:53 pm
Hi,

CB SVN crashes at configure stage, when the recent release of libtool (version 2.2.6) has been installed (no issue with libtool version 2.2.4).

This is caused by modern features of libtool, not by CB itself.
Three build system files should be altered: configure.in, bootstrap and Makefile.am.
Attached is a patch file. To apply it, go to the trunk directory, and run:
  patch -u bootstrap codeblocks.patch

Hope this helps.

best, Fab

what will be the influence of this patch on the old libtool version ??

I just ran ./bootstrap, ./configure, make and make install, without errors.

I got the following messages from libtool:
Code
libtoolize: putting auxiliary files in `.'.
libtoolize: copying file `./ltmain.sh'
libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.in and
libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree.
libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am.

but had no crash, nor any problems with compiling.

libtool is 2.26a-1 and autoconf is 2.63-1, both from debian experimental
automake is 1.10.1-3 and gcc/g++ is 4.2.4-4, both from debian unstable

Hi jens,
I confirm the issue.
I have the same major versions of autotools, compiled from GNU source at ftp.gnu.org, and gcc 4.2/4.3 (ubuntu) or gcc-snapshot (november, source).
Attached is the log (sterr+stdout) of ./boostrap ; ./configure ; make
My autotools normally work OK.
Everything comes back to order with the patch.
Best,
Fab

libtool is a script that is generated by ./bootstrap. The patched ./bootstrap should refresh it accordingly.
If you altered libtool by hand (which is not generally advised), you'll have to copy these amendments into the new libtool again.

The patch breaks bootstrapping on older systems.
I build my nightlies with pbuilder inside a clean debian etch changeroot.
To test the patch I installed autotools and libtools (gcc was already installed) with the following revisions:

Bootstrapping works with a warning:
Code
Remember to add `AC_PROG_LIBTOOL' to `configure.in'.
You should update your `aclocal.m4' by running aclocal.
./configure runs without errors

make stops after following error message:

It seems that LT_PREREQ and LT_INIT are not defined for older libtool-revisions, so ./bootstrap does not even throw an error as expected.

Yes, Jens, you're right.
I forgot to mention that LT_INIT is a non-backward compatible feature of libtool 2.2.6, which is not there in prior versions (which use AC_PROG_LIBTOOL).
Could you do your test again, with the same older platform, yet after replacing LT_INIT and LT_PREREQ with plain AC_PROG_LIBTOOL and AC_DISABLE_STATIC in configure.in, leaving other patched changes as is?
I'd be curious to know the results. On my platform, leaving these is OK after all, yet you still have to add AC_CONFIG_MACRO_DIR([m4]) to configure.in with the patch.

I also tested last night:
it works.

There is also a little change needed for your patch:

in bootstrap the creating of subdir m4 should be conditional, to avoid warnings:

Code
if [ ! -d m4 ]; then
    mkdir m4;
fi

You're right again Jens !
Attached is the modded patch file, which integrates your remarks.
I suggest you could place it as an optional patch somewhere on your unofficial CB repository.
Best, Fab
