cgen 'gas-test' errors

cgen 'gas-test' errors

[Stelian Pop]

Hi all,

I'm working on a new port for binutils/gcc for a custom microcontroller
using CGEN (the latest snapshot version: 20080101).

My host platform is a recent Ubuntu Linux system, with either guile 1.6
or guile 1.8 installed.

When I launch 'make gas-test' (with xc16x in the example) as shown in
the docs, the guile invocation fails with:

cd build-cgen && make gas-test ARCH=xc16x
make[1]: Entering directory `/tmp/build-cgen'
"`if test -f ../guile/libguile/guile ; then echo ../guile/libguile/guile; else echo guile ; fi` -l guile -s" ../cgen-20080101/cgen/cgen-gas.scm \
                -s ../cgen-20080101/cgen \
                -v \
                -a ../cgen-20080101/cgen/../../cpu/xc16x.cpu \
                -i "all" \
                -m "all" \
                -B gas-build.sh \
                -E gas-allinsn.exp
/bin/bash: guile -l guile -s: command not found
make[1]: *** [gas-test] Error 127

This error comes from the invocation of guile in the Makefile, hopefuly the
patch below fixes it.

But even after applying the patch, it fails later with a runtime Scheme error:

make[1]: Entering directory `/tmp/build-cgen'
`if test -f ../guile/libguile/guile ; then echo ../guile/libguile/guile; else echo guile ; fi` -l ../cgen-20080101/cgen/guile.scm -s ../cgen-20080101/cgen/cgen-gas.scm \
                -s ../cgen-20080101/cgen \
                -v \
                -a ../cgen-20080101/cgen/cpu/xc16x.cpu \
                -i "all" \
                -m "all" \
                -B gas-build.sh \
                -E gas-allinsn.exp

This is probably related to my version of guile (1.6 instead of 1.4)...

Can somebody please help me here ? My Scheme skills are very close to zero.

If the changes required to the source are not trivial, I could install guile
1.4 . But I'd rather avoid it if possible.

Thanks !

Stelian.

This generally happens when a newer version of guile does not 
automatically convert some type to a string where an older version of 
guile did. The fix is to find the offending code and insert an explicit 
conversion to string.

I hope this helps,
Dave

I did try to fix the offending code for a few hours, without success. My
knowledge of guile is way too limited. I'll let someone else do it.

Meanwhile I did install guile-1.4.1 and cgen works as it should. BTW, I
was quite surprised to see that installation of this quite old software
(May 2002) did succeed without problems on my recent GNU/Linux distro.

Thanks,

Stelian.
