Mysterious g++ link problems

Mysterious g++ link problems

[David Abrahams]

Here are the symptoms.

    "/usr/local/gcc-3.4.4/bin/g++.exe"   -Wall -ftemplate-depth-100 -O0 -fno-inline -g  -DBOOST_ALL_NO_LIB=1  -I"..\..\.."  -c -o "..\..\..\bin.v2\libs\parameter\test\sfinae.test\gcc-3.4.4\debug\sfinae.o"  "sfinae.cpp"  

    "/usr/local/gcc-3.4.4/bin/g++.exe"     -o "..\..\..\bin.v2\libs\parameter\test\sfinae.test\gcc-3.4.4\debug\sfinae.exe"  "..\..\..\bin.v2\libs\parameter\test\sfinae.test\gcc-3.4.4\debug\sfinae.o"     -g

/usr/lib/gcc/i686-pc-cygwin/3.4.4/libstdc++.a(eh_throw.o):: undefined reference to `___w32_sharedptr_terminate'
collect2: ld returned 1 exit status

This compiler was configured built and installed by me with
--prefix=/usr/local/gcc-3.4.4 and has worked flawlessly up 'till now
(and still works fine on other programs).

Somewhat strangely, 

  > cygcheck -c gcc
  Cygwin Package Information
  Package              Version        Status
  gcc                  3.4.4-1        OK

I think until recently /bin/gcc referred to gcc-3.3.3 on my system,
but I guess a recent use of the Cygwin setup program updated it to
3.4.4.  Everything works fine if I use /bin/g++, so I guess I can just
throw out the contents of /usr/local/gcc-3.4.4, but this is still a
bit disturbing.

  Looks like a clash between the two compilers.  For some reason your
compiler in /usr/local/gcc-3.4.4 is finding and linking against the cygwin
compiler's libstdc in /usr/lib/gcc/.

  Googling for '__w32_sharedptr_terminate throws up....

http://gcc.gnu.org/ml/gcc/2004-04/msg00636.html

which is an inconclusive thread but may perhaps throw some light on the
problem

You are using the wrong libstdc++.a runtime.  Try to figure out why
/usr/local/gcc is using /usr/lig/gcc runtime instead of your own 
/usr/local/lib/gcc runtime.

Suggested solution: either uninstall your local build of gcc and use
the 'official' Cygwin gcc build or uninstall the official release.

I'm not using /usr/local/gcc.  I assume you meant
/usr/local/gcc=3.4.4/bin/g++?

I'd like to try to "figure out why," but I don't know where to start
looking.

I'm happy to use the official one, but I'd still like to understand
what happened.

  Add "-v" to the command line to see exactly how all the sub-programs are
being invoked.

  Compare with the output from "gcc -print-search-dirs".

Yes.  You're calling /usr/local/gcc-3.4.4/bin/g++.exe.  Was the runtime
also installed below /usr/local/gcc-3.4.4/... or maybe it was installed
to /usr/lib/gcc/..., then it wass clobbered by the official release.

Try `/usr/local/gcc-3.4.4/bin/g++.exe -print-search-dirs` or
`/usr/local/gcc-3.4.4/bin/gcc -print-search-dirs`, this gives for
the Cygwin release: libraries: =/usr/lib/gcc/i686-pc-cygwin/3.4.4/:...
