I have been working on the porting of icedtea on the Cavium Octeon server, with MIPS architecture. 
While porting icedtea-1.6 and after a long wait of the make process, it gives error in sanity checking:
 
"Error: The compiler version is undefined"
 
The CC_VER is automaticaly displayed to be 4.3 under the "Build Tool Settings". The COMPILER_VERSION option was empty so I did export COMPILER_VERSION=4.3 after which this is also displayed under the "Build Tool Settings".
The error is still not resolved. Does anyone know how to resolve this? Could this error be reffering to some other compiler instead of gcc?
 
I then tried to port icedtea-1.7 instead. It did not give the error above and passed the sanity check. However after that it gives javac errors while trying to compile the file CompileProperties.java as below:
 
1. ERROR in /home/kics/icedtea-1.7/openjdk-ecj/langtools/make/tools/CompileProperties/CompileProperties.java (at line 220)    [javac]     List<String> sortedKeys = new ArrayList<String>();    [javac]     ^^^^    [javac] The type List is not generic; it cannot be parameterized with arguments <String>    [javac] ----------    [javac] 2.

BUILD FAILED/home/kics/icedtea-1.7/openjdk-ecj/langtools/make/build.xml:575: Compile failed; see the compiler error output for details.
I tried to use all the different java compilers on the server to compile these but the errors were not resolved. Can somone please help me out?
 
Thanks in advance.
