Hi all, I am going to build mor4ansys on a serial linux box (see below for details). The source is available via http://www.imtek.uni-freiburg.de/simulation/mor4ansys/src/mor4ansys-1.8.tar.gz A make yields gcc -c -g -O3 -I/var/tmp/taucs2.2/src/ -I/var/tmp/taucs2.2/build/linux/ -I/var/tmp/UMFPACKv4.4/UMFPACK/Include -I/var/tmp/mor4ansys-1.8/src -I/opt2/ansys_inc/v81/ansys/customize/include mor4ansys.cpp gcc -c -g -O3 -I/var/tmp/taucs2.2/src/ -I/var/tmp/taucs2.2/build/linux/ -I/var/tmp/UMFPACKv4.4/UMFPACK/Include -I/var/tmp/mor4ansys-1.8/src -I/opt2/ansys_inc/v81/ansys/customize/include morbase.cpp gcc -c -g -O3 -I/var/tmp/taucs2.2/src/ -I/var/tmp/taucs2.2/build/linux/ -I/var/tmp/UMFPACKv4.4/UMFPACK/Include -I/var/tmp/mor4ansys-1.8/src -I/opt2/ansys_inc/v81/ansys/customize/include matrices.cpp gcc -c -g -O3 -I/var/tmp/taucs2.2/src/ -I/var/tmp/taucs2.2/build/linux/ -I/var/tmp/UMFPACKv4.4/UMFPACK/Include -I/var/tmp/mor4ansys-1.8/src -I/opt2/ansys_inc/v81/ansys/customize/include ansys.cpp gcc -c -g -O3 -I/var/tmp/taucs2.2/src/ -I/var/tmp/taucs2.2/build/linux/ -I/var/tmp/UMFPACKv4.4/UMFPACK/Include -I/var/tmp/mor4ansys-1.8/src -I/opt2/ansys_inc/v81/ansys/customize/include system.cpp gcc -c -g -O3 -I/var/tmp/taucs2.2/src/ -I/var/tmp/taucs2.2/build/linux/ -I/var/tmp/UMFPACKv4.4/UMFPACK/Include -I/var/tmp/mor4ansys-1.8/src -I/opt2/ansys_inc/v81/ansys/customize/include solvers.cpp gcc -c -g -O3 -I/var/tmp/taucs2.2/src/ -I/var/tmp/taucs2.2/build/linux/ -I/var/tmp/UMFPACKv4.4/UMFPACK/Include -I/var/tmp/mor4ansys-1.8/src -I/opt2/ansys_inc/v81/ansys/customize/include mor.cpp ar crs libmor4ansys.a morbase.o matrices.o ansys.o system.o solvers.o mor.o g++ -s mor4ansys.o libmor4ansys.a -L/home/nwagner/mor4ansys/bin -lbin -L/home/nwagner/mor4ansys/ansys -lCEPCF90 -lPEPCF90 -lintrins -lF90 -lcxa -lcprts -L/var/tmp/taucs2.2/lib/linux -ltaucs -L/var/tmp/UMFPACKv4.4/UMFPACK/Lib -lumfpack -L/var/tmp/UMFPACKv4.4/AMD/Lib -lamd -L/var/tmp/metis-4.0 -lmetis -L/usr/local/lib/atlas -llapack -lf77blas -lcblas -latlas -lg2c -o mor4ansys libmor4ansys.a(matrices.o)(.text+0xca1): In function `SparseMatrix::removeZeros()': /usr/include/g++/bits/stl_alloc.h:430: undefined reference to `std::__default_alloc_template<(bool)1, (int)0>::_S_force_new' libmor4ansys.a(matrices.o)(.text+0xd61):/usr/include/g++/bits/stl_alloc.h:430: undefined reference to `std::__default_alloc_template<(bool)1, (int)0>::_S_force_new' libmor4ansys.a(matrices.o)(.text+0x2c50): In function `SparseMatrix::read(std::basic_istream<char, std::char_traits<char> >&, bool)': /usr/include/g++/bits/stl_alloc.h:430: undefined reference to `std::__default_alloc_template<(bool)1, (int)0>::_S_force_new' libmor4ansys.a(matrices.o)(.text+0x2cc3):/usr/include/g++/bits/stl_alloc.h:430: undefined reference to `std::__default_alloc_template<(bool)1, (int)0>::_S_force_new' libmor4ansys.a(matrices.o)(.text+0x309e):/usr/include/g++/bits/stl_alloc.h:430: undefined reference to `std::__default_alloc_template<(bool)1, (int)0>::_S_force_new' libmor4ansys.a(matrices.o)(.text+0x31a0):/usr/include/g++/bits/stl_alloc.h:430: more undefined references to `std::__default_alloc_template<(bool)1, (int)0>::_S_force_new' follow collect2: ld returned 1 exit status make: *** [mor4ansys] Error 1 Any pointer how to fix this problem would be appreciated.
