libtool 1.4.2
Hi,
here is a patch for Libtool for more control about how libraries
(especially loadable modules) are compiled and linked.
First, a -no-static option is added to (a) not compile static object
files and (b) not create static libtool libraries.
Second, a -soext option is added to override the default file name
extension of shared libraries (.so on most systems).
With this patch applied, my Makefile.am looks like this:
# Matlab MEX-file.
matlabarch_LTLIBRARIES = hell.la
hell_la_SOURCES = hell.c
hell_la_CFLAGS = -no-static \
-DMATLAB_MEX_FILE -I$(MATLAB)/extern/include
hell_la_LDFLAGS = -no-static -module -avoid-version \
-export-symbols mex-symbols -soext .$(MEXEXT)
hell_la_LIBADD = $(MEX_LIBADD)
The result is a working Matlab MEX-file:
$ cd .libs
$ ls -l
10 Sep 19 18:17 hell.la -> ../hell.la
814 Sep 19 18:17 hell.lai
35116 Sep 19 18:17 hell.mexhpux*
$ matlab
>> hell
Hello world!
Good bye sailor!
>> quit
Here's the patch (a second generic libtool patch for better MinGW
support is added below, apply it first if patch rejects some hunks):
