Hi,
I am trying to get the development sources to build on OSX 10.5 using
dependencies installed by MacPorts. Currently my build stops with
libtool: compile: g++-mp-4.3 -DHAVE_CONFIG_H -I. -I..
-I/opt/local/include -I../libgnu -I../libcruft/misc -I../liboctave
-I../liboctave -I. -I. -I/opt/local/include -g -O2 -DHAVE_CONFIG_H -mieee-fp
-I/opt/local/include/freetype2 -I/opt/local/include -I/opt/local/include -Wall
-W -Wshadow -Wold-style-cast -Wformat -g -O2 -D_THREAD_SAFE -g -O2 -MT
liboctinterp_la-builtins.lo -MD -MP -MF .deps/liboctinterp_la-builtins.Tpo -c
builtins.cc -fno-common -DPIC -o .libs/liboctinterp_la-builtins.o
builtins.cc:22405:2: error: #error lex.l requires flex version 2.5.4 or
later
builtins.cc:22632: error: stray '\' in program
[many more stray '\' errors omitted]
[ ... ]
builtins.cc:52: error: expected initializer before '.' token
In file included from /usr/include/fcntl.h:23,
from builtins.cc:46702:
/usr/include/sys/fcntl.h:377: error: expected declaration before end of
line
make[3]: *** [liboctinterp_la-builtins.lo] Error 1
The complaint about my lex version, and the "stray '\'" errors, come
from a section of code that seems to include lex.ll rather than
lex.cc. The "expected initializer" errors come from function
prototypes like
static void install_bitfcns.cc_fcns (void)
If I change the Makefile rule for generating builtins.cc to
builtins.cc: $(DEF_FILES:.ll=.cc) mkbuiltins
$(srcdir)/mkbuiltins $(DEF_FILES:.ll=.cc) > address@hidden
mv address@hidden $@
and change the function name definitions in mkbuiltins to
fcn=`echo "$arg" | $SED 's,.*/,,; s/\.(df|cc)//; s/-/_/g;'`
echo " install_${fcn}_fcns ();"
then the first error becomes
In file included from builtins.cc:77:
../config.h: In function 'void install_bitfcns_cc_fcns()':
../config.h:1317: error: expected unqualified-id before string constant
where the string constant in question comes from a line starting
with 'extern "C" {'. That looks like a pretty standard construction,
so I'm not sure I have made anything better.
I've attached a context diff of the changes I made, just to be clear,
but I appreciate any advice.
Thanks,
Rob
