libmyclass builds successfully, and the test I created for it works fine. I added the myclass/myclass.h/.cpp and the Makefile.PL to the manifest. Added `'-L/home/dr/Abby/XS/Mytest/myclass'` to LIBS. myclass/libmyclass gets mentions in the Makefile as MYEXTLIB. Nothing solved the problem so far. This is the output of the make-command: Skip blib/lib/Mytest.pm (unchanged) cd myclass && make make[1]: Betrete Verzeichnis '/home/dr/Abby/XS/Mytest/myclass' g++ -c -fPIC -O2 -g -DVERSION=\"\" -DXS_VERSION=\"\" -fPIC "-I/usr +/lib/perl/5.14/CORE" myclass.cpp ar cr libmyclass.a myclass.o unitTest.o : libmyclass.a make[1]: Verlasse Verzeichnis '/home/dr/Abby/XS/Mytest/myclass' make[1]: Betrete Verzeichnis '/home/dr/Abby/XS/Mytest/myclass' make[1]: Für das Ziel »all« ist nichts zu tun. make[1]: Verlasse Verzeichnis '/home/dr/Abby/XS/Mytest/myclass' g++ -c -I. -D_REENTRANT -D_GNU_SOURCE -DDEBIAN -fno-strict-aliasing - +pipe -fstack-protector -I/usr/local/include -D_LARGEFILE_SOURCE -D_FI +LE_OFFSET_BITS=64 -O2 -g -DVERSION=\"0.01\" -DXS_VERSION=\"0.01\" - +fPIC "-I/usr/lib/perl/5.14/CORE" Mytest.c Running Mkbootstrap for Mytest () chmod 644 Mytest.bs rm -f blib/arch/auto/Mytest/Mytest.so g++ -shared -O2 -g -L/usr/local/lib -fstack-protector Mytest.o -o bl +ib/arch/auto/Mytest/Mytest.so myclass/libmyclass.a \ \ chmod 755 blib/arch/auto/Mytest/Mytest.so cp Mytest.bs blib/arch/auto/Mytest/Mytest.bs chmod 644 blib/arch/auto/Mytest/Mytest.bs Manifying blib/man3/Mytest.3pm [download] and this for make test make[1]: Betrete Verzeichnis '/home/dr/Abby/XS/Mytest/myclass' make[1]: Für das Ziel »all« ist nichts zu tun. make[1]: Verlasse Verzeichnis '/home/dr/Abby/XS/Mytest/myclass' PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-e" "test_h +arness(0, 'blib/lib', 'blib/arch')" t/.t t/Mytest.t .. 1/2 # Failed test 'use Mytest;' # at t/Mytest.t line 12. # Tried to use 'Mytest'. # Error: Can't load '/home/dr/Abby/XS/Mytest/blib/arch/auto/Mytes +t/Mytest.so' for module Mytest: /home/dr/Abby/XS/Mytest/blib/arch/aut +o/Mytest/Mytest.so: undefined symbol: _ZN7MyClassD1Ev at /usr/lib/per +l/5.14/DynaLoader.pm line 184. # at (eval 4) line 2 # Compilation failed in require at (eval 4) line 2. # BEGIN failed--compilation aborted at (eval 4) line 2.

libmyclass builds successfully, and the test I created for it works fine What files are created with myclass in the name? .. undefined symbol .. What do you get for `ldd -v /home/dr/Abby/XS/Mytest/blib/arch/auto/Mytest/Mytest.so` (see ldd -v ...so / ldd -v ..so like this ) What do you get for when you `objdump -p myclassfiles \| grep MyClass` ( see Re^4: DBD::mysql fail install check (objdump -p missing symbol) )	[reply] [d/l] [select]
