Make fails with xapian custom installation

Make fails with xapian custom installation

[Al Haji-Ali]

Hello,

I have an old version of Xapian installed in root and a new one installed in my home folder which I want to use. My pkgconfig is configured correctly

,----
| ~ pkg-config --libs xapian-core
| -L/home/al/.local/stow/xapian/lib -lxapian
`----

So compiling notmuch works until linking when the following command fails

,----
| ~ c++ lib/filenames.o lib/string-list.o lib/message-file.o lib/message-id.o lib/messages.o lib/sha1.o lib/built-with.o lib/string-map.o lib/indexopts.o lib/tags.o lib/database.o lib/parse-time-vrp.o lib/directory.o lib/index.o lib/message.o lib/add-message.o lib/message-property.o lib/query.o lib/query-fp.o lib/config.o lib/regexp-fields.o lib/thread.o lib/thread-fp.o lib/features.o lib/prefix.o lib/open.o lib/init.o lib/parse-sexp.o  -Wl,--as-needed -L/home/al/.local/stow/gmime/lib -L/usr/lib64 -lgmime-3.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0 -L/usr/lib64 -ltalloc -L/usr/lib64 -lz -L/home/al/.local/stow/xapian/lib -lxapian  -shared -Wl,--version-script=./lib/notmuch.sym,-soname=libnotmuch.so.5 -Wl,--no-undefined -o lib/libnotmuch.so.5.5.0 util/libnotmuch_util.a parse-time-string/libparse-time-string.a
`----

The problem is that GCC orders the library folders left-to-right and the directory `/usr/lib64` is added (multiple times) before the my local directory `/home/al/.local/stow/xapian/lib`. So that the Xapian library file in the /usr/lib64 has a higher priority and is used. Removing all `-L/usr/lib64` manually and running the linking commands, I am able to compile notmuch correctly.

Is there a better way to do this via configure?

Thanks,

configure actually invokes xapian-config rather than pkg-config (I
forget why offhand). So you probably need to set XAPIAN_CONFIG in the
environment to the one in your /home when running configure.

Ah OK. My xapian-config is also correctly configured

,----
| ~ xapian-config --libs
| -L/home/al/.local/stow/xapian/lib -lxapian

Notmuch's configure has the correct paths for Xapian as seen in the compilation command I included before. The issue is the order of library folders.

Does it help if you set LDFLAGS on the make command line?  Looking at
Makefile.global,  LDFLAGS are added before the other computed flags. So
something like

% make V=1 LDFLAGS=-L/home/al/.local/stow/xapian/lib

Yep, this works. Thanks!

I feel that gcc should really have a right-to-left order rather than left-to-right libraries are usually preceded by their directory (like in xapian-config and pkg-config). It's curious that I never ran into this problem before.
