# libsasl: --enable-sql, and the message names a file that exists.

# sql.c:192:10: fatal error: libpq-fe.h: No such file or directory
|
||

#
|
||
|
|
# THE TRAP: the header is there.
|
||
|
|
#
|
||
|
|
# /usr/include/postgresql/libpq-fe.h
|
||
|
|
#
|
||
|
|
# Debian and Ubuntu put the PostgreSQL client headers in a subdirectory, and
|
||
|
|
# the PKGBUILD passes --with-pgsql=/usr/lib, which sends configure looking
|
||
|
|
# somewhere else. "No such file or directory" is true of the path it tried and
|
||
|
|
# false of the file, so the obvious move -- install libpq-dev -- changes
|
||
|
|
# nothing, because it is already installed.
|
||
|
|
#
|
||
|
|
# AND IT IS A QUEUE, WHICH IS THE REAL POINT. The same PKGBUILD passes
|
||
|
|
# --with-mysql=/usr, and mysql.h is at /usr/include/mariadb/mysql.h -- another
|
||
|
|
# subdirectory, another header that exists and cannot be found. Fixing the
|
||
|
|
# first uncovers the second. This port already wrote the rule down, in
|
||
|
|
# install_host_deps, after dbus asked for three documentation tools in a row:
|
||
|
|
# a single missing library is a host dependency; a queue of them is a feature
|
||
|
|
# that should be disabled.
|
||
|
|
#
|
||
|
|
# So the SQL auxprop plugin goes, along with the three --with-*sql flags that
|
||
|
|
# feed it. What it costs is worth stating precisely, because it is nothing:
|
||
|
|
# Arch itself declares depends=(glibc) for this package and says why in a
|
||
|
|
# comment at the top of its own PKGBUILD -- "else this would require mariadb
|
||
|
|
# and postgresql in [core]". The plugins are dlopened, never linked, so
|
||
|
|
# dropping them removes no dependency Arch was tracking and no capability
|
||
|
|
# anything in this port uses. libsasl is here because libldap wants SASL
|
||
|
|
# authentication; that is the DIGEST/GSSAPI/PLAIN side, all still enabled.
|
||
|
|
#
|
||
|
|
# Deferred, not architectural: a server that wants SQL auxprop rebuilds this
|
||
|
|
# with the include paths supplied. TODO.md records it.
