We (Ralph and Jeff) discovered that if the OPAL_DESTDIR environment
variable was set, it was prefixed to ''all'' values in the wrapper
compiler data text files. For example, if OPAL_DESTDIR was set to
/tmp/bogus and a wrapper compiler data file contained the line:
preprocessor_flags=-pthread
The value would be exanded to:
/tmp/bogus/-pthread
Which is clearly wrong. After some back-and-forth with Ralph and
Brian, Brian submitted this patch that fixes the problem. Now we
handle three cases properly (assume that configure was invoked with
--prefix=/opt/openmpi and no other directory specifications, and
$OPAL_DESTDIR is set to /tmp/buildroot):
1. Individual directories, such as libdir. These need to be prepended
with DESTDIR. I.e., return /tmp/buildroot/opt/openmpi/lib.
2. Compiler flags that have ${FIELD} values embedded in them. For
example, consider if a wrapper compiler data file contains the
line:
preprocessor_flags=-DMYFLAG="${prefix}/share/randomthingy/"
The value we should return is:
-DMYFLAG="/tmp/buildroot/opt/openmpi/share/randomthingy/"
3. Compiler flags that do not have any ${FIELD} values. For example,
consider if a wrapper compiler data file contains the line:
preprocessor_flags=-pthread
The value we should return is:
-pthread
Note, too, that this OPAL_DESTDIR futzing only needs to occur during
opal_init(). By the time opal_init() has completed, all values should
be substituted in that need substituting. Hence, we take an extra
parameter (is_setup) to know whether we should do this futzing or
not.
This commit was SVN r23402.
