Hi All, I'm working on getting the JDK7 build working on a Red Hat 4 Linux install, and have run into a problem.
Unfortunately, the "gcc" install (v3.4.6) on my machine is not the version required by the build instructions. Since I don't have root access on my box, I worked on pulling down a more recent version of gcc (v4.3.1) and building it for my Linux machine. In order to build the gcc tool, I needed updated versions of two GNU libraries (GMP, MPFR). Since I can't update /usr/lib with these libraries, I needed to use the --prefix option to build gcc. This works fine for building the compiler, but I run into a problem when I attempt a JDK7 build with ALT_COMPILER_PATH set. While the setting allows me to specify the location of the new gcc binary, there doesn't appear to be a simple way to add any libraries that the new gcc is dependant on. Setting LD_LIBRARY_PATH won't fix the problem, since the build scripts un-set that environment variable in the setup script. If I try setting LD_LIBRARY_PATH after running the "jdk_generic_profile.sh", the build itself fails, since having this environment variable around at all is considered a build failure. I've been able to setup and build OpenJDK on a separate Ubuntu install, but would still like to set this up on my Red Hat machine if possible. If anyone has any thoughts on how I can work around this issue, that would be a big help. Have anyone seen any uses of ALT_COMPILER_PATH that run into this problem? thanks, Bob
