v850-unknown-elf, only simulator needed

[Torsten Mohr]

Hi,

i'd like to configure & compile insight for the target
v850-unknown-elf.  I tried it like this on a Linux
host:
    ../../insight-6.4/configure \
    --target=v850e-unknown-elf \
    --prefix=/opt/v850e \
    --with-newlib \
    --disable-nls \
    --enable-languages="c,c++,java"

But when compiling (make) i get:
configure: error: "*** Gdb does not support target v850e-unknown-elf"

I only want to use the simulator, isn't it possible to
compile insight for v850-unknown-elf?


I try to do all this on Linux, it would be great if it would
also work on MinGW/MSYS.  If it is not possible to compile
insight on MSYS, is it possible to compile gdb on MSYS for
v850-unknown-elf?


Thanks for any hints,
Torsten.

Gdb does not support the build target "v850e-elf". You must use 
v850-elf. That configuration appears to support several of v850 variants 
(v850, v850e, v850e1). You can take a peek at v850-tdep.c to see this.

You can use "make all-sim" instead of "make" or "make all-gdb" to just 
build the simulator. The sim appears to understand what v850e-elf is, 
but I don't know if it supports all the v850 variants in one build like 
gdb. You might ask on the gdb list.

v850-elf should work on any platform supported by gdb. I believe a 
cygwin build will work on mingw. [There is currently work underway in 
gdb-land to produce a mingw version, but I don't know the status of 
that.] Of course, you'd have to carry some cygwin baggage around to do that.

If you require more specific (or authoritative) information about v850 
builds, you should direct your questions to the gdb mailing list 
gdb@sourceware.org. There are many, many people there who know a lot 
more about this stuff than I do. [Or at least more than I remember: I 
did some of the v850 port for gdb many, many years ago.]
