<p>Cygnus is a commercial supplier and supporter of GNU software. It has
|
|
also written several of its own packages, released under the terms of
|
|
the GNU General Public License; and it has taken over the maintenance of
|
|
other packages. Among the packages released by Cygnus are ‘<samp class="samp">gdb</samp>’,
|
|
‘<samp class="samp">gnats</samp>’, and ‘<samp class="samp">dejagnu</samp>’.
|
|
</p>
|
|
<p>Cygnus packages have the peculiarity that each one unpacks into a
|
|
directory tree with a generic top-level Makefile, which is set up to
|
|
compile <em class="emph">all</em> of Cygnus’ packages, any number of which may reside
|
|
under the top-level directory. In other words, even if you’re only
|
|
building ‘<samp class="samp">gnats</samp>’, the top-level Makefile will look for, and try to
|
|
build, <samp class="file">gdb</samp> and <samp class="file">dejagnu</samp> subdirectories, among many others.
|
|
</p>
|
|
<p>The result is that if you try ‘<samp class="samp">make -n install
|
|
prefix=/usr/local/stow/<var class="var">package</var></samp>’ at the top level of a Cygnus
|
|
package, you’ll get a bewildering amount of output. It will then be
|
|
very difficult to visually scan the output to see whether the install
|
|
will proceed correctly. Unfortunately, it’s not always clear how to
|
|
invoke an install from the subdirectory of interest.
|
|
</p>
|
|
<p>In cases like this, the best approach is to run your ‘<samp class="samp">make install
|
|
prefix=<span class="r">…</span></samp>’, but be ready to interrupt it if you detect that it
|
|
is recompiling files. Usually it will work just fine; otherwise,
|
|
install manually.
