I have installed ghc-2.05 on a sparc sunos4 with ghc-0.29 which was
distributed as ghc-0.29-sparc-sun-sunos4. This note may help those
who are going to do same thing.
* Step 1. Preparation ---------------------------------------------------------
I decide that
bindir = /usr/local/bin
libdir = /usr/local/lib/ghc-2.05
and GHC used to make hsc is ghc-0.29 whose path is /usr/local/bin/ghc-0.29.
In addition I installed the following C-Shell script named `ghc-w' on
/usr/local/bin which is a ghc wrapper to rerun ghc with more bigger
heap automatically when the specified size causes heap exhausted.
Since compiling with -O causes very many heap exhausted messages,
I use this script. Though this is awkward, I prefer it to change
many _HC_OPTS params to increase heap limits.
----------------------------- begin ghw-w -----------------------------
#!/bin/csh -f
# A GHC wrapper to rerun ghc with more bigger heap automatically
# when the specified size causes heap exhausted.
set hlimit = 30 # MB Heap increasing limit.
set hstep = 4 # MB And the step added to previous value in each rerun.
usage:
if ($#argv == 0) then
echo 'Usage: ghc-w [-v] ghc args...'
exit 1
endif
if ($argv[1] == -v) then
set verify
shift argv
goto usage
endif
set ghc = $argv[1]
shift argv
set tmp1 = /tmp/tmp1.$$
set tmp2 = /tmp/tmp2.$$
set heap
set hsize = 0
while ($hsize <= $hlimit)
$ghc $argv:q $heap >& $tmp1
set xst = $status # save ghc's exit status
egrep '^while trying to allocate .*byte heap' $tmp1 > $tmp2
if ($status == 0) then
set hsize = `sed 's/^.*in a \([0-9]*\)......-byte.*/\1/' <$tmp2`
@ hsize = $hsize + $hstep
set heap = -H${hsize}m
if ($?verify) then
echo "*** ghc-w ${ghc}: Heap exhausted, rerun ghc with $heap."
endif
else
/bin/sh -c "cat $tmp1 1>&2"
if ($hsize != 0) then
echo "*** ghc-w ${ghc}: $hsize MB heap is required."
endif
goto exit
endif
end
echo "*** ghc-w ${ghc}: The heap can not be increased any more:"
/bin/sh -c "cat $tmp1 1>&2"
exit:
/bin/rm -f $tmp1 $tmp2
exit $xst
------------------------------ end ghw-w ------------------------------
* Step 2. configure & make boot -----------------------------------------------
# ./configure
# make boot
* Step 3. create mk/build.mk --------------------------------------------------
## The contents of the mk/build.mk
WithGhcHc = ghc-w ghc-0.29
HC = ghc-w $(FPTOOLS_TOP)/ghc/driver/ghc
GhcHcOpts = -O
GhcLibHcOpts = -O -split-objs -odir $(basename $*)
SRC_HC_OPTS += -O
libdir = ${exec_prefix}/lib/ghc-2.05
* Step 4. change ghc/compiler/Makefile ----------------------------------------
I don't know why (sorry for my no knowledge of ghc) but the following
line must be added to the Makefile
absCSyn/PprAbsC_HC_OPTS = -Onot
since the file absCSyn/PprAbsC.lhs will not be compiled with -O due to
the following errors:
"codeGen/ClosureInfo.hi", line 72:
undefined type constructor: StgSyn.StgBinderInfo
"codeGen/ClosureInfo.hi", line 74:
undefined type constructor: CgMonad.CgInfoDownwards
[and number of similar errors]
* Step 5. make ----------------------------------------------------------------
Run the following make commands (at midnight :-).
# make all
# make install
* Step 6. re-ranlib -----------------------------------------------------------
re-ranlib was still necessary...
# cd /usr/local/lib/ghc-2.05
# ranlib *.a
-------------------------------------------------------------------------------
Sincerely yours,
