Hi, First of all, forgive my earlier e-mail of "Subscribe" to this. I was a bit confused at the time reading the website. Now for the question.
The team I work with has a project which is a C++ shared library which is exposed in two different manners. The first is a traditional C++ library and the second is it's exposed, through Boost.python, as a module. I found some great references for how to make this happen. However, I've run into a problem: wrapping, in their entirety, the libraries used in making the python module. In brief, the code is laid out thusly: Main (has a Makefile.am and configure.ac files) | |-Shared | | | |- HwMgmt (Makefile.am, makes libhwmgmt.a and libhwmgmt.so) | |- Misc (Makefile.am, likewise for libmisc) | |-sata (Makefile.am, produces libsatacpp.so and sata.so) | | | |-satacpp (sources for the C++ API for SATA lib) | | | |-sata (sources wrapping satacpp in boost.python) Since we distribute this in both a C++ and a python API, I decided to simply use the autotools as they are intended to distribute the whole thing. However, there is a problem. When I build the whole thing, from "Main", the libraries which are built for sata.so (thy python module) aren't yet built. So, they've got to be included, or linked, when we build sata.so. These aren't simply convenience libraries. So, for example, using "noinst_LTLIBRARIES = libhwmgmt.la" isn't acceptable. However, the *.a files made must be entirely included into the python module. In our former, home-baked, makefile arrangement, we just built them up and included them as follows: gcc ... -Wl,--whole-archive /path/to/first.a, /path/to/second.a -Wl,--no-whole-archive I'm trying to reproduce this using the automake tools. I have this in the Makefile.am located in sata: lib_LTLIBRARIES = satacpp.la satacpp_la_SOURCES = ... pyexec_LTLIBRAIRES = sata.la sata_la_LDFLAGS = -module sata_la_LIBADD = -Wl,--whole-archive ../Shared/HwMgmt/.libs/libhwmgmt.a ../Shared/Misc/.libs/libmisc.a .libs/libsata.a -Wl,--no-whole-archive -lz -lrt As I'm sure no one here will be surprised, this causes automake to fail because, "linker flags such as '-Wl,--whole-archive' belong in sata_la_LDFLAGS." However, when I place this there, I find that Makefile.in and the final Makefile have things where I expect them, but when make runs, the libraries I've specified to be included as "whole-archive" are not listed between this option. Instead, they are listed earlier and *nothing is listed* between -Wl,--whole-archive -Wl,--no-whole-archive. I assume that libtool is doing this for me. I'm using automake version 1.11.1, autoconf 2.63. Any help is greatly appreciated. Andy
