Hi,
Bug summary: compilation with libtool fails if user has an environment
variable D (and probably for S, too).
Description: while compiling a package that uses libtool, I ran into a
strange problem where paths to libraries like
/disk1/jester/IPP/bla/bla
got turned into
/IPP/bla/bla
and since that directory does not exist, much less contain the required
library, compilation fails in the libtool call.
It turns out that the failure is caused by one or more of these snippets
from ltmain.sh:
# We do not want portage's install root ($D) present. Check only
for
# this if the .la is being installed.
if test $installed = yes test $D; then
eval mynewdependency_lib=`echo $libdir/$name |sed -e s:$D:/:g
-e 's:/\+:/:g'`
else
mynewdependency_lib=$libdir/$name
fi
...
# We do not want portage's install root ($D) present.
my_little_ninja_foo_3=`echo $deplib |$EGREP -e $D`
if test -n $my_little_ninja_foo_2 test $S; then
mynewdependency_lib=
elif test -n $my_little_ninja_foo_3 test $D; then
eval mynewdependency_lib=`echo $deplib |sed -e s:$D:/:g -e
's:/\+:/:g'`
else
mynewdependency_lib=$deplib
fi
...
# Do not add duplicates
if test $installed = yes test $D; then
install_libdir=`echo $install_libdir |sed -e s:$D:/:g -e
's:/\+:/:g'`
fi
together with the fact that I use an environment variable D =
/disk1/jester (in this case) on every machine I have an account on
that points to my non-home-area data disk. Compilation works as
expected if I unset D.
I don't understand how libtool works and don't know what portage is,
so I can't offer a fix. Clearly, global environment variable names
like D and S are very very bad programming style for a
maximum-portability tool such as libtool (sorry to be so
blunt) so probably the straightforward fix is to rename them into
PORTAGE_INSTALL_ROOT_D or something like that
(MY_LITTLE_NINJA_FOO_D is very descriptive, too ;-)
This is the version info for ltmain.sh:
PROGRAM=ltmain.sh
PACKAGE=libtool
VERSION=1.5.22
TIMESTAMP= (1.1220.2.365 2005/12/18 22:14:06)
Cheers,
