XCOMM Construct shared-library export lists for HP-UX based on standardized
|
|
XCOMM export list description file
|
|
XCOMM
|
|
XCOMM Usage: exportlistgen libfoo.sl libfoo.elist > libfoo.lopt
|
|
XCOMM
|
|
XCOMM libfoo.sl => shared library of interest
|
|
XCOMM libfoo.elist => Meta description of necessary export list.
|
|
XCOMM
|
|
XCOMM The output may then be passed to the linker to reconstruct the
|
|
XCOMM shared library. For unknown reasons naming only exported symbols
|
|
XCOMM with "+e" does not work for debuggable C++ code, even though "nm"
|
|
XCOMM reports no difference between the resulting libraries. The linker
|
|
XCOMM complains that "first non-inline virtual function" is not defined for
|
|
XCOMM vtables. We instead hide internal symbols with "-h" as a work-around.
