adainclude subdirectory containing the sources of the GNAT
run-time library, and the
adalib subdirectory containing the
ALI files and the static and/or shared GNAT library, are located
in the gcc target-dependent area:
As indicated above, on some platforms several run-time libraries are supplied. These libraries are installed in the target dependent area and contain a complete source and binary subdirectory. The detailed description below explains the differences between the different libraries in terms of their thread support.
The default run-time library (when GNAT is installed) is `rts-native'. This default run time is selected by the means of soft links. For example on x86-linux:
-- -- $(target-dir) -- | -- +--- adainclude----------+ -- | | -- +--- adalib-----------+ | -- | | | -- +--- rts-native | | -- | | | | -- | +--- adainclude <---+ -- | | | -- | +--- adalib <----+ -- | -- +--- rts-sjlj -- | -- +--- adainclude -- | -- +--- adalib
If the `rts-sjlj' library is to be selected on a permanent basis, these soft links can be modified with the following commands:
$ cd $target $ rm -f adainclude adalib $ ln -s rts-sjlj/adainclude adainclude $ ln -s rts-sjlj/adalib adalib
Alternatively, you can specify
rts-sjlj/adainclude in the file
Selecting another run-time library temporarily can be achieved by using the `–RTS' switch, e.g., `–RTS=sjlj'
