Cppunit wont link without -Wl,--no-as-needed

[Richard Eames]

I may be doing something stupid here, but I think it's a bug with the package in precise, since it used to work before I upgraded.

I definitely have libcppunit and -dev installed:
$ apt-cache policy libcppunit-dev
libcppunit-dev:
  Installed: 1.12.1-4
  Candidate: 1.12.1-4
  Version table:
 *** 1.12.1-4 0

$ apt-cache policy libcppunit-1.12-1
libcppunit-1.12-1:
  Installed: 1.12.1-4
  Candidate: 1.12.1-4
  Version table:
 *** 1.12.1-4 0

$ ls /usr/lib/ | grep cppunit
libcppunit-1.12.so.1
libcppunit-1.12.so.1.0.0
libcppunit.a
libcppunit.la
libcppunit.so

$ sudo ldconfig -p |grep cppunit
 libcppunit-1.12.so.1 (libc6,x86-64) => /usr/lib/libcppunit-1.12.so.1

But if I try to link with the attached sample program I get linker errors:

$ g++ -lcppunit -o test.bin test.cpp
/tmp/ccoQDuGC.o: In function `main':

Current work around is to add "-Wl,--no-as-needed" before "-lcppunit". So this leads me to believe the package might not have been built properly.

currently, with cppunit 1.15.1, this works flawleslly, and I also doubt this had been a problem for long since --as-need has been default gcc behaviour in ubuntu for years already.
