Public bug reported: Binary package hint: mingw32
I have a C++ DLL which uses stdc++ features. Mingw32 on Ubuntu lucid is unable to link this. Compilation fails with: libtool: link: /usr/bin/i586-mingw32msvc-g++ -shared -nostdlib /usr/lib/gcc/i586-mingw32msvc/4.2.1-sjlj/../../../../i586-mingw32msvc/lib/dllcrt2.o /usr/lib/gcc/i586-mingw32msvc/4.2.1-sjlj/crtbegin.o .libs/VImage.o .libs/VError.o .libs/VDisplay.o .libs/VMask.o -L/home/john/windows/win/lib ../libvips/.libs/libvips.dll.a -lMagickWand -lMagickCore -lpng12 -ltiff -lz -ljpeg -lgthread-2.0 -lxml2 -lpangoft2-1.0 -lpango-1.0 -lfreetype -lfontconfig -lgobject-2.0 -lgmodule-2.0 -lglib-2.0 -lintl -lfftw3 -llcms -lexif -L/usr/lib/gcc/i586-mingw32msvc/4.2.1-sjlj -L/usr/lib/gcc/i586-mingw32msvc/4.2.1-sjlj/../../../../i586-mingw32msvc/lib -lstdc++ -lmingw32 -lgcc -lmoldname -lmingwex -lmsvcrt -luser32 -lkernel32 -ladvapi32 -lshell32 -lmingw32 -lgcc -lmoldname -lmingwex -lmsvcrt /usr/lib/gcc/i586-mingw32msvc/4.2.1-sjlj/crtend.o -mno-cygwin -mms-bitfields -march=i686 -Wl,--enable-auto-import -mno-cygwin -mms-bitfields -march=i686 -mno-cygwin -o .libs/libvipsCC-15.dll -Wl,--enable-auto-image-base -Xlinker --out-implib -Xlinker .libs/libvipsCC.dll.a Creating library file: .libs/libvipsCC.dll.a .libs/VError.o:VError.cc:(.text+0x21): undefined reference to `__imp___ZNSt8ios_base4InitC1Ev' [... snip ... more undefined references follow, about half are errors linking to ios init, half to exception init] It builds C DLLs correctly. If I make my own mingw32 cross-compiler following the instructions at http://www.mingw.org/wiki/LinuxCrossMinGW everything works perfectly. This process also worked well in karmic. It seems to be only the lucid package which has this problem.
