This is version 0.0 of the unwind library. At the moment, only the
|
|
IA-64 Linux (IPF Linux) platform is supported and even that support
|
|
has received only light testing. Consequently, this release is
|
|
intended primarily to expose the unwind API to more developers and to
|
|
collect feedback on what does and does not work. Having said that,
|
|
backtracing through gcc-generated code might work reasonably well.
|
|
|
|
There is virtually no documentation at the moment. A brief outline of
|
|
the unwind API is in file NOTES. To get a feel for how things are
|
|
intended to work, you may also want to take a look at include/unwind.h
|
|
and include/unwind-ia64.h. Finally, the test program in
|
|
src/tests/bt.c shows two ways of how to do a simple backtrace: one
|
|
uses libunwind directly, the other uses a libunwind-based
|
|
implementation of the backtrace() function. The test program in
|
|
src/tests/exc.c shows the basics of how to do exception handling with
|
|
this library.
|
|
|
|
The following steps should be used to compile and install this library:
|
|
|
|
$ cd src
|
|
$ make dep
|
|
$ make
|
|
$ make install prefix=PREFIX
|
|
|
|
where PREFIX is the installation prefix. By default, a prefix of /usr
|
|
is used, such that libunwind.a is installed in /usr/lib and unwind.h
|
|
is installed in /usr/include. For testing, you may want to use a
|
|
prefix of /usr/local instead.
