Hi there,
one of the headaches using ports gives me is that it requires too much
attention. Let me explain this. Think a port that can link in
libmysqlclient.so.1{0,2}, and will function the same with either of
them. Most ports today will
a) LIB_DEPENDS on one of them, meaning you'll have to hack the port
Makefile
b) let you choose, with a (arbitrary) default
Both options are a PITA when doing mass upgrades, or when you just
install something that has a decent amount of dependencies, which in
turn... Think Postfix, or PHP.
I'm proposing this "macro" to be put in bsd.port.mk:
GET_INSTALLED_LIBRARY=myLib=`${LDCONFIG} -r | ${GREP} -Fwe l${CHECKLIB} | \
${SED} -E 's/^.+:-l${CHECKLIB}\.([[:digit:]]+) =>.+/\1/'`; \
xLib=-1; for l in $${myLib}; do \
if [ $${xLib} -lt $${l} ]; then xLib=$${l}; fi \
done; \
if [ -1 -eq $${xLib} ]; then xLib=${DEFLTVER}; fi; echo $${xLib}
example usage:
MYSQL_VERSION_LIB10=323
MYSQL_VERSION_LIB12=40
.if defined(WITH_MYSQL323)
MYSQL_LIB_VERSION=10
.elif defined(WITH_MYSQL40)
MYSQL_LIB_VERSION=12
.elif defined(WITH_MYSQL)
CHECKLIB=mysqlclient
DEFLTVER=12
MYSQL_LIB_VERSION!=${GET_INSTALLED_LIBRARY}
.endif
LIB_DEPENDS+=mysqlclient.${MYSQL_LIB_VERSION}:${PORTSDIR}/databases/mysql${MYSQL_VERSION_LIB${MYSQL_LIB_VERSION}}-client
CONFIGURE_ARGS+=--with-mysql=${LOCALBASE}
.endif
It's more verbose, but will do the right thing whichever version the
user has installed (or even none), as opposed to thrashing their install
with another version.
