1.- OK.  The "distrib/hc-build" migth not handle the dependencies soundly.

Now I build on the target T as in the host H:

cd hslibs/ && gmake boot && gmake
cd ghc	 && gmake boot && gmake

The "touch config.h" patch seems to solve the stg_ap_v_ret bug...

2.- Now the problem seems to be another one:

bash-2.05$ ghc/compiler/ghc-inplace  hello.hs

crash, and tracing the core it seems a problem having to do with gmp
software:

bash-2.05a$ gdb ghc-6.0.1 core

# 0x1153a208 in __decodeFloat ()

if I apply the "-v" flag, then

bash-2.05$ ghc/compiler/ghc-inplace -v hello.hs
bash-2.05a$ gdb ghc-6.0.1  core

# 0x11554ae4 in __gmpn_tdiv_qr / ( qp=0x454ed518 ...)

Any idea ?

3) Simon M. : For the time beeing this is the patch you can integrate
safely into the CVS repository . I have read-only permissions. There is no
doubt on it.-------------- next part --------------
