From 70b77a0fc329e2e205a596a738c7307d354e7b1c Mon Sep 17 00:00:00 2001 From: Mike Gabriel Date: Tue, 14 Apr 2015 09:24:55 +0200 Subject: library clean-up: Don't build and link libXfont.a anymore. Use system's libXfont shared library and link dynamically. --- nx-X11/lib/font/bitmap/Imakefile | 71 -- nx-X11/lib/font/bitmap/bdfint.h | 90 -- nx-X11/lib/font/bitmap/bdfread.c | 967 -------------- nx-X11/lib/font/bitmap/bdfutils.c | 340 ----- nx-X11/lib/font/bitmap/bitmap.c | 160 --- nx-X11/lib/font/bitmap/bitmapfunc.c | 240 ---- nx-X11/lib/font/bitmap/bitmaputil.c | 232 ---- nx-X11/lib/font/bitmap/bitscale.c | 1978 ----------------------------- nx-X11/lib/font/bitmap/fontink.c | 219 ---- nx-X11/lib/font/bitmap/module/Imakefile | 45 -
