openslp: unable to infer tagged configuration

[ryandesign (Ryan Carsten Schmidt)]

I can't seem to build openslp @1.2.1_2 anymore:

if /bin/sh ../libtool --mode=compile ccache /usr/bin/gcc-4.2 -DHAVE_CONFIG_H -I. -I. -I..   -I/opt/local/include  -DNDEBUG -D_REENTRANT=1 -pipe -O2 -arch x86_64 -Wall -O3 -MT slp_compare.lo -MD -MP -MF ".deps/slp_compare.Tpo" -c -o slp_compare.lo slp_compare.c; \
	then mv -f ".deps/slp_compare.Tpo" ".deps/slp_compare.Plo"; else rm -f ".deps/slp_compare.Tpo"; exit 1; fi
libtool: compile: unable to infer tagged configuration
libtool: compile: specify a tag with `--tag'
make[2]: *** [slp_compare.lo] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

openslp @1.2.1_2 is currently installed on this Mac, installed on October 26, 2010, so something must have changed since then. The changes made in #27022 seem to be the cause. Though r73793 was intended to make a universal build of openslp possible, for me it seems to have the effect of preventing both universal and non-universal builds.

Works for me.

If you didn't have libtool installed, it would have created a broken link which could have done something funny.

[ryandesign (Ryan Carsten Schmidt)]

libtool @2.4_0+universal is installed and active (built Sep 23, 2010).

difference between my old libtool 2.4 and the newly built one

[ryandesign (Ryan Carsten Schmidt)]

I rebuilt libtool, and now openslp builds. I attached a diff of the changes made to the installed files between the old libtool and the new one. The difference is that the new one references ccache. I only recently enabled ccache in macports.conf, and it appears that the use or non-use of ccache needs to be indicated in libtool for libtool to work. This seems like something that we should do something about, or at least document somehow. I'm still worried about what happens when I try to build a port that uses libtool while ccache is enabled (and encoded into the libtool files) but that port disables ccache.

[nerdling (Jeremy Lavergne)]

Similarly I rebuilt libtool from source (rather than using the archive from packages.macports.org) and all was well again. I don't have ccache enabled on this end: 10.6.8 xcode 4.0.2

As the error message says: specify a tag with `--tag'.
