Howdy all!
I am using automake and autoconf with an Earth science library called
netCDF.
In my testing, if --enable-large-file-tests is used with configure, I
run some tests which create very large files, like 4 GB and over.
To accommodate this on machines with disk quotas, I want to allow the
user to specify to configure a directory in which large files can be
created during testing.
But how do I do that?
I have the following, which captures the value (defaulting to "."):
# If the env. variable TEMP_LARGE is set, or if
# --with-temp-large=<directory>, use it as a place for the large
# (i.e. > 2 GiB) files created during the large file testing.
AC_MSG_CHECKING([where to put large temp files if large file tests are run])
AC_ARG_WITH([temp-large],
[AS_HELP_STRING([--with-temp-large=<directory>],
[Specify directory where large files (i.e. >2 GB)
will be written, if large files tests are run.])],
[TEMP_LARGE=$with_temp_large])
TEMP_LARGE=${TEMP_LARGE-.}
AC_MSG_RESULT($TEMP_LARGE)
AC_SUBST(TEMP_LARGE)
But how do I use TEMP_LARGE when running my test program?
I have tried running a test script, and using $TEMP_LARGE in the
script. This works if I supply TEMP_LARGE on the command line with the
make command, but it doesn't pick up the TEMP_LARGE defined during
configure.
So how do I take TEMP_LARGE and get it into one of my test programs?
Any suggestions welcome.
Thanks!
Ed
