Mac Compile Help

[jamesl73]

I'm trying to follow the wiki instructions for Mac and mixing in some of the instructions from Unix. I've tried to follow a couple of the other threads on Mac compiling, but they're pretty long with information spread all over the place. If I can get this to work I'll summarize and post the information so the wiki can be updated.

My attempts so far are using Macports.

I'm able to compile OpenCascade just fine.

Running autogen.sh I get a bunch of errors like this

src/Mod/Robot/App/Makefile.am:17: warning: source file 'kdl_cp/velocityprofile_traphalf.cpp' is in a subdirectory,
src/Mod/Robot/App/Makefile.am:17: but option 'subdir-objects' is disabled

The sample configure command on the wiki has a path to Qt

/usr/local/Trolltech/Qt-4.8.0

but mine is

/usr/local/Qt4.8

so I updated the configre command accordingly, but when I run configure, here are a few errors I'm getting

checking for eigen3... checking for /usr/include/eigen3/Eigen... no
checking for /usr/local/include/eigen3... no
checking Eigen/Eigenvalues usability... no
checking Eigen/Eigenvalues presence... no
checking for Eigen/Eigenvalues... no
configure: WARNING:
**** Cannot find eigen3 devel files.
Modules that depend on this library cannot be built. ****

I have eigen3 installed via macports and also downloaded from the website and copied the Eigen directory as stated in the wiki

checking whether Qt is installed as framework... yes
checking whether QtWebKit is available... yes
checking for Qt >= 4.3... configure: error: Cannot find Qt meta object compiler (moc), bye...

I have qt4-mac installed via macports and also tried downloading and installing Qt


I also gave it a shot using cmake as in the Unix instructions

I tried to add Spnav, but when I went to compile it, it says not supported on Darwin.

Sorry for the long post. Hope someone can help.

autotools are not supported anymore, you will not be able to compile freeCAD with them. Use cmake. And I belive you dont need spacenav, you will just miss that feature. Cmake did genererate the build files, so everything seems ok. The missing python files are strange, do you have swig installed? maybe thats the reason, not sure... Just try compiling and see where it fails

[jamesl73]

I do have swig installed via macports.

running make produces these errors

hm coin3d is missing. strange, cmake should have detected that. you need to install it and set the path.

[jamesl73]

Confirmed Coin is already installed via macports.

[ickby]

than make sure that the cmake variable points to the right include dir. I dont know the exact name right now, should be something like COIN§D_INCLUDE_DIR (and COIN3D_LIBRARY_DIR for linking)

[jamesl73]

I downloaded Coin and SoQT and compiled manually. Now I'm getting a little farther in make. I'm not clear what this error is telling me.

[ickby]

the gnu fortran library can not be found by the linker. Make sure it's in the system path.

[jamesl73]

I was using g95 for fortran, but couldn't find gfortran. I installed gcc46 to get gfortran, cleaned out the build folder and reran cmake and make and still get the error.
