../configure --target=i370-mvspdp --prefix=/devel/mvscross
--with-sysroot=/devel/mvshead
--enable-languages=c
plus make and make install
then I went to
mvscross/bin and renamed i370-mvspdp-gcc to i370-mvspdp-xxx
and replaced it with a script that does:
i370-mvspdp-xxx -S $*
Maybe a more generic way to work around the missing assembler and linker
would be to provide dummy scripts i370-mvspdp-as
I created one of them, but as far as I can tell it didn't pick it up.
and i370-mvspdp-ld, where
the "assembler" would simply copy the assembler source input as text to
the
"object" file output, and the "linker" would collect all input files into
a tar file (or some other archive) as "executable" output ...
Sounds good.
This would allow usual build processes (including "make") to proceed as
expected.
Yes.
The compiler error output found in the config.log file should hopefully
point to the problem ...
Well, below are some of the changes I made today to get it to go
past the various errors. Probably the most interesting was this
one:
! #define BIG_ENDIAN 1
! #define LITTLE_ENDIAN 2
! #define BYTE_ORDER 1
I don't have a sys/param.h and so I just stuck those in somewhere
that it seemed to be looking for, so that it didn't come up and say
that it couldn't determine the endian order.
It seemed to try very hard to stick in sys/types.h and sys/time.h
and I'm not sure how well I got around that.
It also seemed to execute /bin/as at one point instead of my
dummy cross-assembler. I'll try to figure out what the logic
is tomorrow.
Note - all this is on 3.4.6.
BFN. Paul.
