Dear All,
I have some code that I am trying to build with the aid of libtool,
autoconf and automake. I require both a static and shared library of my
code, and libtool provides this functionality beautifully.
However I need to pass separate CPPFLAGS to the objects destined for the
shared library as opposed to the objects destined for the library archive.
----------example------------------
gcc file.c -c -DSTATIC
ar cru libfile.a file.o
gcc file.c -c -DSHARED
gcc -shared file.o -o libfile.so.0
-------------------------------------
In my Makefile.am I have
lib_LTLIBRARIES = libfile.la
libfile_la_SOURCES....
libfile_la_CPPFLAGS.....
libfile_la_LDFLAGS......
which then goes to produce libfile.a and libfile.so with the same
CPPFLAGS, so I added
- libfile_a_CPPFLAGS.....
but didnt do anything.
So i did AC_DISABLE_STATIC in my configure.ac and added
- lib_LIBRARIES = libfile.a
to my Maakefile.am and used a AM_CONDITIONAL+AC_ARG_ENABLE for my own
--enable-static-lib
This setup works. But for some odd reason, whenever "make install", is
invoked, libfile.so is recompiled again (including all the individual
objects). Which is a little redundant but harmless nonetheless.
Can someone suggest a way I can produce both a static and shared library
with libtool/autoconf/automake that are compiled with different CPPFLAGS?
Thank you,
Vikram
