I have been trying to make 0.6.1 work under OpenMCL Version 1.1-pre-061231
(DarwinX8664). However, as I mentioned before, I have been having compilation
problems.
They seem to be mainly related to libmemutil.
Out of the box attempt, I got the following error:
; $ /usr/bin/gcc -shared -Wall -fPIC -O3 -o
/Users/dev/lisp/elephant/src/memutil/libmemutil.so
/Users/dev/lisp/elephant/src/memutil/libmemutil.c -lm
i686-apple-darwin8-gcc-4.0.1: unrecognized option '-shared'
/usr/bin/ld: Undefined symbols:
_main
collect2: ld returned 1 exit status
Upon inspection of elephant.asd, I made the following change:
(defmethod compiler-options ((compiler (eql :gcc)) (c elephant-c-source) &key
input-file output-file)
"Default compile and link options to create a library; no -L or -I options
included; math lib as default"
(unless (and input-file output-file)
(error "Must specify both input and output files"))
(list
#-(or openmcl darwin macosx) "-shared"
#+(or openmcl darwin macosx) "-bundle"
"-Wall"
"-fPIC"
"-O3"
"-o" output-file
input-file
"-lm"))
What I basically did is I added "openmcl" to the conditionalization #- and #+.
After making this change, it successfully builds the libmemutil.so file.
However, while the file actually exists, it fails to load with the following
message:
Error opening shared library
"/Users/dev/lisp/elephant/src/memutil/libmemutil.so":
dlopen(/Users/dev/lisp/elephant/src/memutil/libmemutil.so, 10): no suitable
image found. Did find:
/Users/dev/lisp/elephant/src/memutil/libmemutil.so: mach-o, but wrong
architecture
[Condition of type SIMPLE-ERROR]
FYI, my *FEATURES* is:
(:KMR-NORMAL-DSDC :KMR-NORMAL-CESD :KMR-MOP :ASDF :PRIMARY-CLASSES :COMMON-LISP
:OPENMCL :CLOZURE :ANSI-CL :UNIX :OPENMCL-NATIVE-THREADS :OPENMCL-PARTIAL-MOP
:MCL-COMMON-MOP-SUBSET :OPENMCL-MOP-2 :OPENMCL-PRIVATE-HASH-TABLES
:OPENMCL-HASH-CONSING :X86-64 :X86-64 :X86-TARGET :X86-HOST :X8664-TARGET
:X8664-HOST :DARWIN-HOST :DARWIN-TARGET :DARWINX86-TARGET :DARWINX8664-TARGET
:DARWINX8664-HOST :POWEROPEN-TARGET :64-BIT-TARGET :64-BIT-HOST
:LITTLE-ENDIAN-TARGET :LITTLE-ENDIAN-HOST :MCL)
I don't really know why it cannot load the shared library. I don't know if the
problem is basically a compat issue with this CVS version of OpenMCL in this
architecture and/or UFFI. However, I thought I would share this just in case
anyone has information that could speed this process or any suggestions of what
I may try next.
Thanks,
Daniel
