4<para><userinput>patch -Np1 -i
5../ncurses-&ncurses-version;-patch:</userinput> This patch fixes a compile
6problem with GCC-3.2 because Ncurses uses constructions that are no longer
7valid in the new C++ standard.</para>
8
9<para><userinput>--with-shared:</userinput> This enables the build of the
10shared ncurses library files.</para>
11
12<para><userinput>mv /lib/*.a /usr/lib :</userinput> This
13moves all of the static ncurses library files from /lib to /usr/lib.
14/lib should only contain the shared files which are essential to the
15system when /usr may not be mounted.</para>
16
17<para><userinput>chmod 755 *.5.2:</userinput> Shared libraries should be
18executable. Ncurses install routine doesn't set the permissions
19properly so we do it manually instead.</para>
20
21<para><userinput>ln -sf libncurses.a libcurses.a:</userinput> Some
22programs try to link using -lcurses instead of -lncurses. This symlink
23ensures that such programs will link without errors.</para>
24
25<para><userinput>ln -sf ../../lib/libncurses.so etc:</userinput> These
26symlinks are created to tidy up the installation. It's good practice to
27have the *.so files in /usr/lib as well as in /lib, to ensure that the
28linker is always able to find the files whether it's looking in /lib or
29/usr/lib.</para>
