the configure script do not fail if swig is not available

[GoogleCodeExporter]

Hello,

without swig the configure process run without error
but make gives this error

make[1]: entrant dans le répertoire « /home/picca/Projets/coot/src »
swig -o coot_wrap_guile_pre_gtk2.cc -DCOOT_USE_GTK2_INTERFACE  
-DHAVE_SYS_STDTYPES_H=0   -DUSE_LIBCURL -I../src -guile -c++  ../src/coot.i
/bin/bash: swig : commande introuvable

so it seems that swig is mendatory.
Can you teach configure.in to fail if swig is not available or do not compile 
the swig code if it is not available.

thanks

Frederic

on debian/Ubuntu the swig executable is called swig2.0
so hard coding the swig name is a bad idea. the swig autotools macro take care 
of this.

This problem should be resolved now (post June 2013) - configure/build no 
longer needs swig.

But I can still find swig command in the Makefile.am, so this can cause some 
troubles during the build.

picca@mordor:~/Projets/coot$ find . -name Makefile.am | xargs grep swig
./src/Makefile.am:                             
$(top_srcdir)/src/c-interface-ligands-swig.hh \
./src/Makefile.am:      swig -o $@ -DCOOT_USE_GTK2_INTERFACE 
$(ENTERPRISE_TOOLS_CFLAGS) $(WITH_GUILE_CFLAGS)  $(USE_LIBCURL) 
-I$(top_srcdir)/src -guile -c++  $(top_srcdir)/src/coot.i
./src/Makefile.am:                              
$(top_srcdir)/src/c-interface-ligands-swig.hh \
./src/Makefile.am:      swig -o $@ -DCOOT_USE_GTK2_INTERFACE 
$(ENTERPRISE_TOOLS_CFLAGS) $(PYTHON_CFLAGS)  $(USE_LIBCURL) -I$(top_srcdir)/src 
-shadow -python -c++ $(top_srcdir)/src/coot.i && mv coot.py coot_gtk2.py

I can confirm that
./configure && make

still failed due to this swig commands. So swig is still required during the 
build of coot.
