Building OpenCascade in Slackware64 13


Hi Forum

I have been trying to build the OpenCascade release 6.3.0 in my Slackware box...

This takes looong like sh**t... and I get frustrated like hell, because :

1. the thing actually builds, after 3 hrs or so of compiling...
2. If i try to enable some other stuff to use the opencascade libraries, like netGen, Freecad, or Gmsh, they fail to build with the opencascade enable features, like IGES/Brep import/export...

I have googled abit ... and I have successfully built and liked against it in Arch...

I used the AUR package...

and I have applied the patches suggested in the PKGBUILD... and ran these scripts in order to get stuff to compile properly :


tweak1.sh
Quote:
# Adjusts reference to X11 libraries and headers
for _FILE in `grep -R -l "/usr/X11R6/lib" src/*`
do
sed -e "s|/usr/X11R6/lib|/usr/lib64/X11|g" -i $_FILE
done
for _FILE in `grep -R -l "/usr/X11R6/include" src/*`
do
sed -e "s|/usr/X11R6/include|/usr/include/X11|g" -i $_FILE
done
changed /usr/lib... to /usr/lib64, bcause this is Slackware, not Arch

and

tweak2.sh

Quote:
# Adjusts DESTDIR prefix in Makefile.am and reconfigures files
sed -e "s| \$(prefix)| \$(DESTDIR)\$(prefix)|g" -i Makefile.am
autoreconf -f -i

# Copy some file we need from source to the installation dir
install -d -m 755 "${pkgdir}$_installdir"
cp -r "${srcdir}/OpenCASCADE$pkgver/data" \
"${srcdir}/OpenCASCADE$pkgver/samples" \
"${srcdir}/OpenCASCADE$pkgver/adm" \
"${srcdir}/OpenCASCADE$pkgver/drv" \
"${srcdir}/OpenCASCADE$pkgver/make" \
"${srcdir}/OpenCASCADE$pkgver/src" \
"${pkgdir}${_installdir}"
after having defined the variables defined in tweak2.sh

... I have updated CXXFLAGS, CASROOT, as well as sourcing env.sh prior to ./configuring, and making...

But somehow I am not getting a good feeling about this...

In arch it compiles much faster than it does in slackware...

I guess some things are not set up properly...

Is there a slackbuild for OpenCascade...?
