Steve,
I'm CC'ing you on this discussion because it looks like a name
mangling bug in the latest Sun C++ compiler. The linker produces this
error message:
Undefined???first referenced
symbol ??? in file
const char*boost::date_time::nth_as_str(int) /home/user1/dgregor/
BoostRegressionTesting/results/boost/bin.v2/libs/date_time/test/
testfacet_dll.test/sun-5.8/debug/testfacet.o
ld: fatal: Symbol referencing errors. No output written to /home/
user1/dgregor/BoostRegressionTesting/results/boost/bin.v2/libs/
date_time/test/testfacet_dll.test/sun-5.8/debug/testfacet_dll
Grepping for nth_as_str in the library, we see two symbols:
-bash-2.05b$ nm libboost_date_time-sw58-gd-1_34.so.1.34.0 |grep
nth_as_str
0002628c D $XAsX$TB_yJqEWnE.__1cFboostJdate_timeL_nth_as_str_
00013ad8 T __1cFboostJdate_timeKnth_as_str6Fki_pkc_
I don't know what that first symbol is, but the second one is clearly
what we want:
-bash-2.05b$ c++filt
__1cFboostJdate_timeKnth_as_str6Fki_pkc_
const char*boost::date_time::nth_as_str(const int)
The problem is that the compiler is putting "const" into the mangled
name for the definition, but it shouldn't be there.
Jeff, it looks like you can work around this bug by removing "const"
from "const int ele" in src/gregorian/date_generators.cpp.
Cheers,
Doug
