Subject: [PATCH 1/3] GDB: Run `pkg-config' with `--static' to pull libguile dependencies
Date: Thu, 24 Nov 2022 23:51:09 +0000 (GMT) [thread overview]
Message-ID: <alpine.DEB.2.20.2211241907010.19931@tpp.orcam.me.uk> (raw)
In-Reply-To: <alpine.DEB.2.20.2211241701270.19931@tpp.orcam.me.uk>
Fix a configuration error:
checking whether to use guile... guile-2.2
checking for pkg-config... /usr/bin/pkg-config
checking for usable guile from /usr/bin/pkg-config... checking for scm_set_automatic_finalization_enabled... no
configure: error: in `.../gdb':
configure: error: linking guile version guile-2.2 test program failed
See `config.log' for more details
make[1]: *** [Makefile:12160: configure-gdb] Error 1
coming from link errors as recorded in `config.log' referred:
configure:19349: checking for scm_set_automatic_finalization_enabled
configure:19349: gcc -o conftest -pipe -O2 -pthread -I.../include/guile/2.2 conftest.c -lncursesw -lm -ldl -L.../lib -lguile-2.2 -lgc >&5
/usr/bin/ld: .../lib/libguile-2.2.a(libguile_2.2_la-ports.o): in function `scm_ungetc':
(.text+0x5561): undefined reference to `u32_conv_to_encoding'
/usr/bin/ld: (.text+0x56e1): undefined reference to `u32_to_u8'
etc., etc., in a valid configuration where a static version of libguile
has only been installed, which is a pefectly valid system configuration.
This is due to symbols being required from libguile's dependencies that
have not been included in the linker invocation.
In configurations using the ELF format dynamic libguile implicitly pulls
indirect dependencies in the link, but to satisfy static libguile they
need to be named explicitly. These dependencies have been recorded and
can be supplied by `pkg-config', but for that to happen the tool has to
be invoked with the `--static' option in addition to `--libs'. Moreover
it is recommended, at least with systems using the ELF format, to have
indirect dependencies included with static linker invocation even where
they all are satisfied by dynamic libraries.
Therefore fix the issue by using the `--static' option unconditionally
with `pkg-config', adding the dependencies required:
configure:19349: gcc -o conftest -pipe -O2 -pthread -I.../include/guile/2.2 conftest.c -lncursesw -lm -ldl -L.../lib -lguile-2.2 -lgc -lgmp -lltdl -lffi -lunistring -lcrypt -lm >&5
and removing the errors quoted above.
