When statically linking programs against libguile-2.0.a, I get
unresolved externals. This is on MS-Windows, but I don't think this
is related to the problem.
I finally traced that to the contents of guile-2.0.pc file:
Libs: -L${libdir} -lguile-2.0 -Ld:/usr/lib -lgc
Libs.private: d:/usr/lib/libgmp.dll.a -Ld:/usr/lib d:/usr/lib/libltdl.dll.a -Ld:/usr/lib -lffi -lregex -lcrypt -lws2_32 -lm
However, libguile-2.0.la shows more dependency libraries:
dependency_libs=' -lgc -lffi -lunistring -liconv -lregex -lintl -liconv -lgmp -ltdl -lregex -lintl -lwsock32 -lole32 -luuid -lmsvcp60 -lcrypt -lws2_32'
As you see, quite a few libraries are missing from guile-2.0.pc, and
also a several libraries need to appear more than once in the link
command line.
Why doesn't the Guile build process put all of the libraries in the
.pc file?
I could easily work around this by editing guile-2.0.pc manually, but
isn't this supposed to happen automatically?
Any help would be appreciated.

Commit 58f86505d658359508732c8f187bc37d010074d0 (see below) should solve most of that, but not all, since I don’t know where -lole32, and -lregex come from, for example.

It seems to me that adding a fixed list of indirect dependencies to guile-2.0.pc.in is the wrong approach, because the indirect dependencies may depend on the platform, as well as the specific versions/variants of any of the direct or indirect dependencies. How do other programs that use 'pkg-config' deal with this issue? Are they all broken in this way? If we really need the full list of indirect dependencies, maybe we should somehow extract it from the generated .la file?

For the record, most of those added in 58f86505d658359508732c8f187bc37d010074d0 are empty on GNU systems, for instance. So it’s really an OS-dependent list. > How do other programs that use 'pkg-config' deal with this issue? > Are they all broken in this way? Yes, AFAIK. > If we really need the full list of indirect dependencies, maybe we > should somehow extract it from the generated .la file? That sounds right, but slightly nasty. Keep in mind that the only issue could be for users linking without Libtool, and in the even that ‘Libs.private’ is outdated compared to what the actual dependency list.

"-lregex" is needed by regex-posix.c (naturally ;-), since the default Windows libraries do not include regcomp, regexec, etc. There's a test in configure that first check the standard library link, then "-lregex" and "-lrx". However, @GUILE_LIBS@ already gets edited to include -lregex, so there's no problems here. "-lole32" (and a few others) come from libregex.la. However, the standard link command for the program I'm building (GNU Make, btw) already includes these libraries even without Guile, so using your modified guile-2.0.pc.in, I was able to link the program successfully with no unresolved externals. Btw, shouldn't guile-2.0-uninstalled.pc.in get the same changes? Thanks! ^ permalink raw reply [flat|nested] 6+ messages in thread
