ReverseEngineering module fails to compile due to bug in cmake script?

[kcleung]

I am compiling the git default head commit 711213d58e355d643b4b2e68f8fd8eb2bb7db0ea on Ubuntu 16.04 with cmake 3.5.1. However it fails when compiling ReverseEngineering, and apparently due to some form of cmake script problems:


[ 72%] Built target RobotGui
[ 72%] Generating ../../../../Mod/ReverseEngineering/Init.py

src/Mod/ReverseEngineering/App/CMakeFiles/ReverseEngineering.dir/depend.make:4: *** missing separator. Stop.

However, when I looked at the abovementioned files, I didn't see any spacing problems.

Can anyone try it out on Linux?

Hi,
everything works ok here. CMake 3.5.2

OS: Debian GNU/Linux unstable (sid)
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.17.7623 (Git)
Build type: Debug
Branch: master
Hash: f9d28145727f15f4abb00d18e2f3ed85e95bbb4b
Python version: 2.7.11+
Qt version: 4.8.7
Coin version: 4.0.0a
OCC version: 6.8.0.oce-0.17

EDIT:
After googling it seems that your generated Makefile has some spaces instead of tabs.

Cheers,
Mateusz

I know the generated Makefile has space instead of tabs! But why are spaces generated? Is it be cause of some bugs in our cmake scripts, or is it becasue a bug in cmake 3.5.1?

Hi.
Hmm. That is rather confusing...

Anyway...

I've tried building latest master on Ubuntu Xenial. It compiles without any problems. The same goes for Debian Sid. Both were Debug builds.

Maybe you should try building from scratch in a fresh build directory?

I have just upgraded cmake from 3.5.1 to 3.5.2, and also in a fresh build directory, but no success.

Actually I build freecad off-site in a separate directory. this is what I did:

git clone ....... /* clone to FreeCAD */

$ mkdir freecad-bin /* the build directory */
$ cd freecad-bin
$ cmake ../FreeCAD /* the source directory */
$ make


However I hosted the freecad source and build directories in the host filesystem (OS X), and the ubuntu is actually installed in a VMware fusion virtual machine, and the source and build directories fro the host FS is made available to the ubuntu VM by directory sharing through VMware fusion

However I hosted the freecad source and build directories in the host filesystem (OS X)

Under Windows I have a virtual Ubuntu that can access the source directory of the host. However, I must choose a build directory inside the guest OS because otherwise I get many problems.

You are right. I have just successfully built inside the guest OS. Thanks for your help!
