Hi, I found configure of http://hg.openjdk.java.net/jdk/jdk was broken on MIPS.
the output of configure: ... configure: Using default toolchain gcc (GNU Compiler Collection) checking for gcc... /usr/bin/gcc checking resolved symbolic links for CC... /usr/bin/mips64el-linux-gnuabi64-gcc-6 configure: Using gcc C compiler version 6.3.0 [gcc (Debian 6.3.0-18) 6.3.0 20170516] checking whether the C compiler works... no configure: error: in `/home/loongson/aoqi/jdk': configure: error: C compiler cannot create executables See `config.log' for more details configure exiting with result code 77 ... the related content of config.log: ... configure:35256: checking whether the C compiler works configure:35278: /usr/bin/gcc -m64 -m64 conftest.c >&5 gcc: error: unrecognized command line option '-m64' gcc: error: unrecognized command line option '-m64' configure:35282: $? = 1 configure:35320: result: no configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "OpenJDK" | #define PACKAGE_TARNAME "openjdk" | #define PACKAGE_VERSION "jdk9" | #define PACKAGE_STRING "OpenJDK jdk9" | #define PACKAGE_BUGREPORT "build-dev@openjdk.java.net" | #define PACKAGE_URL "http://openjdk.java.net"; | /* end confdefs.h. */ | | int | main () | { | | ; | return 0; | } configure:35325: error: in `/home/loongson/aoqi/jdk': configure:35327: error: C compiler cannot create executables See `config.log' for more details ... I made a small patch to pass the configure: $ hg diff make/autoconf/flags.m4 diff -r 3acb379b8672 make/autoconf/flags.m4 --- a/make/autoconf/flags.m4 Thu Mar 22 08:09:51 2018 +0800 +++ b/make/autoconf/flags.m4 Thu Mar 22 12:55:00 2018 +0800 @@ -237,7 +237,11 @@ MACHINE_FLAG="-q${OPENJDK_TARGET_CPU_BITS}" elif test "x$TOOLCHAIN_TYPE" != xmicrosoft; then if test "x$OPENJDK_TARGET_CPU" != xaarch64 && - test "x$OPENJDK_TARGET_CPU" != xarm; then + test "x$OPENJDK_TARGET_CPU" != xarm && + test "x$OPENJDK_TARGET_CPU" != xmips && + test "x$OPENJDK_TARGET_CPU" != xmipsel && + test "x$OPENJDK_TARGET_CPU" != xmips64 && + test "x$OPENJDK_TARGET_CPU" != xmips64el; then MACHINE_FLAG="-m${OPENJDK_TARGET_CPU_BITS}" fi fi I think this is the same problem with bug 8199052 and 8199152. Could someone help to review the change? Thanks, Ao Qi
