[Buildroot] Libtool relinking problem

[Buildroot] Libtool relinking problem

[John Voltz]

I'm wondering if anyone else has noticed problems when installing some
libraries to the staging_dir, sometimes libtool will place a  random
dependency reference as /usr/lib/xxx.la instead of
$(STAGING_DIR)/usr/lib/xxx.la.

This appears to be caused by the libtool re-linking during install.
Anybody know what to do to fix this? I tried adding
LDFLAGS="-L$(STAGING_DIR)/usr/lib" to make install, but it didn't
help.

Thanks,

John Voltz

I noticed this too, and I also noticed that it only happens when
selecting the "Generic Development System" option.  I never had time to
trace down what goes wrong when doing that though... 
Hope this helps.

Unsure why some libraries fail to install with correct path while others
manage to do $(DESTDIR)/$(PREFIX)/lib/libxxx.la.

I usually add a $(SED) to the Buildroot Makefile to correct the
libxxx.la file.

$(SED) "s,^libdir=.*,libdir=\'$(STAGING_DIR)/usr/lib\',g" $(STAGING_DIR)/usr/lib/libxxx.la

Fiddling with LDFLAGS, CFLAGS, etc to solve an issue is seldom the right
solution.

The sed command in Makefile.autotools.in is not terminated with the
letter g. So it only fixes one problem in the line!
