Tips and tasks when updating freetype sources to a newer version. ----------------------------------------------------------------- The freetype sources here are just the subset needed by JDK. This is deliberate. When updating be sure to import only the same files. If a file is no longer present in freetype, or renamed this will be noticed during the copy. Occasionally there may be a new missing dependency if freetype introduces a new file or imports a file into these files that was not previously used. Import just what is needed. Before attempting compilation be sure to diff the JDK copy and the freetype copy of src/java.desktop/share/native/libfreetype/include/freetype/config/ftoption.h and re-apply the same edits made for the JDK option file. Notably JDK is not using GZIP or LZW or BDF support which are on by default for the freetype distribution. If you don't make the edits the build will fail due to not copying the relevant sources. Use "expand" and "sed" to remove tabs and trailing white space from the imported sources. The current version of freetype is quite clean in this respect. ./src/base/md5.h and ./src/base/md5.c are the only files with tabs, and ./include/freetype/ftdriver.h has the only trailing white space. If you forget this step, or aren't thorough, jcheck will remind you. Remember to update the freetype version identified in src/java.desktop/share/legal/freetype.md
