[kaffe] Problem in build

[Pinaki Mukherjee]

Hi,

After working on the problem, I got some clue. I was able to build Kaffe
(after doing a 'make clean' first). But when I ran 'make check', I
started getting errors. These are basically compilation errors while
creating the class files for the testcases.

This is happenening only when I am changing a data structure of type
struct called 'slots' in the file .../kaffe/kaffevm/intrp/slots.h. I am
just adding another field (int size[2]) to the 'slots' struct, so that
it looks like..
typedef struct _slots {
        int size[2];
        union {
                jint            tint;
                jword           tword;
                jlong           tlong;
                jfloat          tfloat;
                jdouble         tdouble;
                void*           taddr;
                char*           tstr;
        } v;
} slots;

I am not changing any other source file. Strangely, the Kaffe executable
is getting compiled, but the testcase java files are not compiling. I
cannot understand why this is happeneing. Below is the compilation error
I'm getting for the Java testcase files while running 'make check'.

Hi,

I am trying to build Kaffe after making some changes in the VM (some
files in the .../kaffe/kaffevm and .../kaffe/kaffevm/intrp directories).
I am getting the following error message:

*******************************

Can somebody please tell me what's wrong. It seems there is some problem
with the files in the
`/workspace/pinaki/kaffe-1.1.4/test/regression/compile_time' directory,
though I haven't touched it at all. As a matter of fact, earlier I was
being able to build the executable. I have been using the following
options with 'configure' : --enable-pure-java-math, --prefix <some
directory name> and --with-engine=intrp.

Please help.

Thanks a lot.

Pinaki
