BTW, when I compiled MPC I met trouble with complex.h, after searched on the web, I commented out the complex.h in config.h.in /* Define to 1 if you have the <complex.h> header file. */ //#undef HAVE_COMPLEX_H When "make check", there's some error, but the install was completed. Did you ever met the same problem? 2011/4/19 Jonathan Wakely <jwakely.gcc@xxxxxxxxx>: > On 19 April 2011 13:09, Qi Zuo wrote: >> >> -bash-3.00$ /lab/home/zuoqi/gcc32/gcc-gnu-ccs/bin/g++ hello.cpp >> /var/tmp//ccDqluzK.o: In function `main': >> hello.cpp:(.text+0x20): undefined reference to `std::cout' >> hello.cpp:(.text+0x24): undefined reference to `std::cout' >> hello.cpp:(.text+0x48): undefined reference to >> `std::basic_ostream<char, std::char_traits<char> >>>::operator<<(std::basic_ostream<char, std::char_traits<char> >& >> (*)(std::basic_ostream<char, std::char_traits<char> >&))' >> collect2: ld returned 1 exit status >> >> the paths checked by -v as following >> >> -bash-3.00$ /lab/home/zuoqi/gcc32/gcc-gnu-ccs/bin/g++ hello.cpp -v >> Using built-in specs. >> COLLECT_GCC=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/bin/g++ >> COLLECT_LTO_WRAPPER=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/libexec/gcc/sparc-sun-solaris2.10/4.6.0/lto-wrapper >> Target: sparc-sun-solaris2.10 >> Configured with: ../gcc-4.6.0/configure ABI=32 >> --prefix=/lab/home/zuoqi/gcc32/gcc-gnu-ccs --with-gnu-as >> --with-as=/usr/local/bin/as --with-gnu-ld --with-ld=/usr/local/bin/ld >> --enable-languages=c,c++,java >> --with-gmp-include=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/include >> --with-gmp-lib=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/lib >> --with-mpfr-include=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/include >> --with-mpfr-lib=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/lib >> --with-mpc-include=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/include >> --with-mpc-lib=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/lib --without-ppl >> --without-cloog --enable-plugin --enable-lto >> Thread model: posix >> gcc version 4.6.0 (GCC) > ... >> LIBRARY_PATH=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/lib/gcc/sparc-sun-solaris2.10/4.6.0/:/usr/ccs/lib/:/lab/home/zuoqi/gcc32/gcc-gnu-ccs/lib/gcc/sparc-sun-solaris2.10/4.6.0/../../../:/lib/:/usr/lib/ > > > I suggest you look in these paths to find libstdc++.so and then run > 'nm' on it to see if it contains the missing symbols. > -- Regards Qi Zuo School Of Computer Science and Technology Beijng Institute of Technology, China, 100081
