Вот, уважаемый ALL, приятель просил вопрос спросить. Сам я в приплюснутом ноль, поэтому у знатаков спрашиваю.

Сейчас ругается линкер:

karennhullsurface.o(.text+0x1274): In function `KarennHullSurface::parseForBodyPoints()':
: undefined reference to `KarennNurbsSurface::doApproxX(p5d const&, p5d const&, double)'
karennhullsurface.o(.text+0x194b): In function `KarennHullSurface::parseForBreadthPoints()':
: undefined reference to `KarennNurbsSurface::doApproxZ(p5d const&, p5d const&, double)'
karennhullsurface.o(.text+0x2354): In function `KarennHullSurface::parseForProfilePoints()':
: undefined reference to `KarennNurbsSurface::doApproxY(p5d const&, p5d const&, double)'
karennhullsurface.o(.text+0x25f0): In function `KarennHullSurface::parseForProfilePoints()':
: undefined reference to `KarennNurbsSurface::doApproxY(p5d const&, p5d const&, double)'
collect2: ld returned 1 exit status
make[2]: *** [karenn] Ошибка 1

хотя вроде бы inline функции определены, вот одна из них:

inline
p5d KarennNurbsSurface::doApproxX(const p5d& p1, const p5d& p2, double inX) {
    double du;
    p5d result;
    du=(inX-p1.x)/(p2.x-p1.x);
    result.x=inX;
    result.y=p1.y +(p2.y-p1.y)*du;
    result.z=p1.z+ (p2.z-p1.z)*du;
    result.u=p1.u+(p2.u-p1.u)*du;
    result.v=p1.v+(p2.v-p1.v)*du;
    return result;
}

Это хде?

# ./configure --help
`configure' configures this package to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print `checking...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for `--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or `..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [/usr/local/kde]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, `make install' will install all the files in
`/usr/local/kde/bin', `/usr/local/kde/lib' etc.  You can specify
an installation prefix other than `/usr/local/kde' using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR           user executables [EPREFIX/bin]
  --sbindir=DIR          system admin executables [EPREFIX/sbin]
  --libexecdir=DIR       program executables [EPREFIX/libexec]
  --datadir=DIR          read-only architecture-independent data [PREFIX/share]
  --sysconfdir=DIR       read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR   modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR    modifiable single-machine data [PREFIX/var]
  --libdir=DIR           object code libraries [EPREFIX/lib]
  --includedir=DIR       C header files [PREFIX/include]
  --oldincludedir=DIR    C header files for non-gcc [/usr/include]
  --infodir=DIR          info documentation [PREFIX/info]
  --mandir=DIR           man documentation [PREFIX/man]

Program names:
  --program-prefix=PREFIX            prepend PREFIX to installed program names
  --program-suffix=SUFFIX            append SUFFIX to installed program names
  --program-transform-name=PROGRAM   run sed PROGRAM on installed program names

System types:
  --build=BUILD     configure for building on BUILD [guessed]
  --host=HOST       build programs to run on HOST [BUILD]
  --target=TARGET   configure for building compilers for TARGET [HOST]

Optional Features:
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --disable-fast-perl     disable fast Makefile generation (needs perl)
  --enable-debug=ARG    enables debug symbols (yes|no|full) default=no
  --disable-debug         disables debug output and debug symbols default=no
  --enable-strict         compiles with strict compiler options (may not work!)
  --disable-warnings      disables compilation with -Wall and similiar
  --enable-profile        creates profiling infos default=no
  --enable-pch            enables precompiled header support (currently only KCC) default=no
  --enable-final          build size optimized apps (experimental - needs lots of memory)
  --disable-closure       don't delay template instantiation
  --enable-shared[=PKGS]
                          build shared libraries [default=yes]
  --enable-static[=PKGS]
                          build static libraries [default=no]
  --enable-fast-install[=PKGS]
                          optimize for fast installation [default=yes]
  --disable-libtool-lock  avoid locking (might break parallel builds)
  --enable-objprelink     prelink apps using objprelink (experimental only tested on linux/386)
  --enable-embedded       link to Qt-embedded, don't use X
  --enable-qtopia         link to Qt-embedded, link to the Qtopia Environment
  --disable-mt            link to non-threaded Qt (deprecated)
  --enable-kernel-threads Enable the use of the LinuxThreads port on FreeBSD/i386 only.
  --disable-threading     disables threading even if libpthread found
  --disable-rpath         do not use the rpath feature of ld
  --disable-path-check    don't try to find out, where to install

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-gnu-ld           assume the C compiler uses GNU ld [default=no]
  --with-pic              try to use only PIC/non-PIC objects [default=use
                          both]
  --with-tags=TAGS        include additional configurations [CXX,GCJ]
  --with-xinerama         enable support for Xinerama
  --with-extra-includes=DIR
                          adds non standard include paths
  --with-extra-libs=DIR   adds non standard library paths
  --with-qt-dir=DIR       where the root of Qt is installed
  --with-qt-includes=DIR  where the Qt includes are.
  --with-qt-libraries=DIR where the Qt library is installed.

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
              headers in a nonstandard directory <include dir>
  CPP         C preprocessor
  CXX         C++ compiler command
  CXXFLAGS    C++ compiler flags
  CXXCPP      C++ preprocessor

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

мопед не мой, я просто разместил объяву (ц)

Линкер правильно делает, что ругается. Функция класса определена как inline -- это задача компилятора разместить ее в коде. Компилятор должен видеть что она inline (проверьте определение класса) и иметь текст inline-функции (можно включить прямо в .h файл).

Обходные пути -- удалите спецификатор inline или включите текст функции прямо в определение класса.
