I'm having trouble getting IRSTLM to compile, due to an apparent problem linking to the ltmain.sh file in the libtool directories. I'm using Cygwin, by the way.

cook@mt-g66 /cygdrive/c/irstlm/trunk
$ ./regenerate-makefiles.sh
Calling /usr/bin/libtoolize
libtoolize: putting auxiliary files in '../..'.
libtoolize:   error: linking '/usr/share/libtool/build-aux/ltmain.sh' to '../../' failed
libtoolize failed

Could someone please point me in the right direction as to how to overcome this? I've double-checked that Cygwin installed libtool, but I'm very new to Cygwin, so there may be a step that I've overlooked. I have little experience of compiling applications generally, but have been unable to locate an installer version of IRSTLM.

Thanks

first of all you need to install the dependencies ...thats why you got something like this ibtoolize: error: linking '/usr/share/libtool/build-aux/ltmain.sh' to '../../' failed libtoolize failed

so follow the steps one by one ...

  1. Get the source from here http://sourceforge.net/projects/irstlm/

  2. Installing some dependencies

    sudo apt-get install build-essential sudo apt-get install automake sudo apt-get install libtool sudo apt-get install zlib1g-dev

  3. Extracting files

    sudo mkdir -p /usr/local/src/irstlm sudo chown username /usr/local/src/irstlm tar -xvzf irstlm.tgz -C /usr/local/src/irstlm

  4. Compiling

    sudo mkdir -p /usr/local/lib/irstlm sudo chown username /usr/local/lib/irstlm ./regenerate-makefiles.sh ./configure --prefix=/usr/local/lib/irstlm --enable-caching make -j 4

  5. Installing

    make -j 4 install

good luck ..!

  • Thank you for the advice. There's one small glitch, and that's that sudo does not work in Cygwin. Is there a workaround for this? – user3289842 Sep 02 '15 at 08:33
  • i never tried cygwin. but i thing you can try :- [link](http://superuser.com/questions/304541/how-to-install-new-packages-on-cygwin). – Miller Sep 02 '15 at 10:30
  • It seems to have worked, by prefixing apt-get with runas instead of sudo. Elsewhere, it worked when I dispensed with suno. – user3289842 Sep 02 '15 at 11:46

there's actually another situation that can cause the libtoolize that was not really addressed here. Permission and access issues. Consider the following situation: you're in virtualbox and trying to run libtoolize out of a VBox Shared folder, you will get this error. Move the project within the machine, error is gone.
