I'm trying to install the mldonkey using MacPorts 1.520 installed in a intel mac with tiger running on it and i've got the following error message: ---> Building ocaml with target world.opt Error: Target org.macports.build returned: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_ocaml/work/ocaml-3.10.0" && unset LD_PREBIND LD_PREBIND_ALLOW_OVERLAP && make world.opt " returned error 2 Command output: cp byterun/ocamlrun boot/ocamlrun cd yacc; make all make[1]: Nothing to be done for `all'. cp yacc/ocamlyacc boot/ocamlyacc cd stdlib; make COMPILER=../boot/ocamlc all make[1]: Nothing to be done for `all'. cd stdlib; cp stdlib.cma std_exit.cmo *.cmi camlheader ../boot if test -f boot/libcamlrun.a; then :; else \ ln -s ../byterun/libcamlrun.a boot/libcamlrun.a; fi if test -d stdlib/caml; then :; else \ ln -s ../byterun stdlib/caml; fi cd byterun; make all make[1]: Nothing to be done for `all'. if test -f stdlib/libcamlrun.a; then :; else \ ln -s ../byterun/libcamlrun.a stdlib/libcamlrun.a; fi cd yacc; make all make[1]: Nothing to be done for `all'. cd lex; make all make[1]: Nothing to be done for `all'. cd tools; make all make[1]: Nothing to be done for `all'. cd stdlib; make all make[1]: Nothing to be done for `all'. cd asmrun; make all gcc -I../byterun -DCAML_NAME_SPACE -DNATIVE_CODE -DTARGET_i386 -DSYS_macosx -O -Wall -D_FILE_OFFSET_BITS=64 -D_REENTRANT -c -o signals_asm.o signals_asm.c signals_asm.c: In function 'segv_handler': signals_asm.c:193: error: 'struct mcontext' has no member named '__ss' signals_asm.c:193: error: 'struct mcontext' has no member named '__ss' make[1]: *** [signals_asm.o] Error 1 make: *** [runtimeopt] Error 2 Error: The following dependencies failed to build: lablgtk ocaml Error: Status 1 encountered during processing. ------------------------------------------------------------------------------------------- I've installed Ocaml 3.10.0 before the installtion of mac ports from a .dmg file downloaded from INRIA site and i don't know if the problem has something to do with this prior installation.
