Hi Phil, it looks like the recent png lib change 8183960: Upgrade to libpng 1.6.34
http://hg.openjdk.java.net/jdk/hs/rev/791d551bcdb8 +#if PNG_POWERPC_VSX_OPT > 0 +# define PNG_FILTER_OPTIMIZATIONS png_init_filter_functions_vsx +# define PNG_POWERPC_VSX_IMPLEMENTATION 1 +#endif Causes build errors in our linuxppc64le openjdk jdk-hs (fast)dbg build . We get this linker error : pngrutil.c:(.text+0x4824): undefined reference to `png_init_filter_functions_vsx' Do you have a version of libpng available that contains the missing function png_init_filter_functions_vsx ? Or do you have an idea where it should come from (I cannot find it in the main libpng sources). To fix the build, we could probably disable the part bringing in png_init_filter_functions_vsx in png_init_filter_functions_vsx . Thanks, Matthias Error message : * /hs/support/native/java.desktop/libsplashscreen/pngrutil.o: In function `png_read_filter_row': * pngrutil.c:(.text+0x4824): undefined reference to `png_init_filter_functions_vsx' * collect2: error: ld returned 1 exit status * Awt2dLibraries.gmk:928: recipe for target '/hs/support/modules_libs/java.desktop/libsplashscreen.so' failed
