I tried to build b21 on my Ubuntu 7.04 and got: /work/java.net/openjdk.trunk/control/build/linux-amd64/tmp/sun/sun.awt/splashscreen/obj64/png.o: In function `png_init_mmx_flags': png.c:(.text+0xbc): undefined reference to `png_mmx_support' /work/java.net/openjdk.trunk/control/build/linux-amd64/tmp/sun/sun.awt/splashscreen/obj64/pngpread.o: In function `png_push_process_row': pngpread.c:(.text+0x86e): undefined reference to `png_read_filter_row' pngpread.c:(.text+0x934): undefined reference to `png_do_read_interlace' /work/java.net/openjdk.trunk/control/build/linux-amd64/tmp/sun/sun.awt/splashscreen/obj64/pngpread.o: In function `png_progressive_combine_row': pngpread.c:(.text+0x141): undefined reference to `png_combine_row' /work/java.net/openjdk.trunk/control/build/linux-amd64/tmp/sun/sun.awt/splashscreen/obj64/pngread.o: In function `png_read_row': pngread.c:(.text+0xa7d): undefined reference to `png_combine_row' pngread.c:(.text+0xbd8): undefined reference to `png_combine_row' pngread.c:(.text+0xbfc): undefined reference to `png_combine_row' pngread.c:(.text+0xc98): undefined reference to `png_combine_row' /work/java.net/openjdk.trunk/control/build/linux-amd64/tmp/sun/sun.awt/splashscreen/obj64/pngread.o: pngread.c:(.text+0xcb4): more undefined references to `png_combine_row' follow /work/java.net/openjdk.trunk/control/build/linux-amd64/tmp/sun/sun.awt/splashscreen/obj64/pngread.o: In function `png_read_row': pngread.c:(.text+0xce5): undefined reference to `png_read_filter_row' pngread.c:(.text+0xd0d): undefined reference to `png_do_read_interlace' collect2: ld returned 1 exit status make[3]: *** [/work/java.net/openjdk.trunk/control/build/linux-amd64/lib/amd64/libsplashscreen.so] Error 1 make[3]: Leaving directory `/work/java.net/openjdk.trunk/j2se/make/sun/splashscreen'
I found this thread talking about it: http://mail.openjdk.java.net/pipermail/distro-pkg-dev/2007-August/000192.html So, I tried to modified the makefile to use the system png. It's very roughly removing the integrated libpng and linking with png12. Here is the patch: https://www.jfrog.org/svn-jfrog/openjdk/patch/SplashScreen_libpng12.patch Hope it helps. -- http://freddy33.bglogspot.com/ http://www.jfrog.org/
