Hi,

I need to install a software package on Unix. When I ran
"./configure", I got the following error message:

configure: error: Couldn't find ltdl.h which is required and
part of the libtool distribution.  You probably
need to define an include path via a -I in CPPFLAGS

I know where ltdl.h is, but don't know how to add -I in CPPFLAGS.

Thanks in advance.

Derek

Perhaps a shell variable will solve this:
export CPPFLAGS=-Isomewhere
./configure

If you use a cshell type shell, the above syntax won't work. I believe
the correct syntax for setting an environment variable in cshell type
shells is as follows:

setenv CPPFLAGS -I/path/to/ltdl.h
./configure

--Mac

Probably better to keep any old settings:
export CPPFLAGS="$CPPFLAGS -Isomewhere"
and something similar if using csh.
