dnl ---------------

dnl Check if the compiler supports useful warning options. There's a few that

dnl we don't use, simply because they're too noisy:
|
|
dnl
|
|
dnl -Wconversion (useful in older versions of gcc, but not in gcc 2.7.x)
|
|
dnl -Wredundant-decls (system headers make this too noisy)
|
|
dnl -Wtraditional (combines too many unrelated messages, only a few useful)
|
|
dnl -Wwrite-strings (too noisy, but should review occasionally). This
|
|
dnl is enabled for ncurses using "--enable-const".
|
|
dnl -pedantic
|
|
dnl
|
|
dnl Parameter:
|
|
dnl $1 is an optional list of gcc warning flags that a particular
|
|
dnl application might want to use, e.g., "no-unused" for
|
|
dnl -Wno-unused

dnl Attempt to determine the appropriate CC/LD options for creating a shared
|
|
dnl library.
|
|
dnl
|
|
dnl Notes:
|
|
dnl a) ${LOCAL_LDFLAGS} is used to link executables that will run within
|
|
dnl the build-tree, i.e., by making use of the libraries that are compiled in
|
|
dnl $rel_builddir/lib We avoid compiling-in a $rel_builddir/lib path for the
|
|
dnl shared library since that can lead to unexpected results at runtime.
|
|
dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
|
|
dnl libraries are compiled in ../../lib
|
|
dnl
|
|
dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
|
|
dnl to install symbolic links to the rel/abi versions of shared libraries.
|
|
dnl
|
|
dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
|
|
dnl version when making symbolic links.
|
|
dnl
|
|
dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
|
|
dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
|
|
dnl (ex: libncurses.so.<ver>).
|
|
dnl
|
|
dnl Some loaders leave 'so_locations' lying around. It's nice to clean up.
