effect -DCMAKE_INSTALL_PREFIX on existing FC builds

[Jee-Bee]

I have a compiled version of FreeCAD on my ubuntu VM
now i want create another version while checking the cmake.txt i saw this function -DCMAKE_INSTALL_PREFIX
when compiling multiple versions of FreeCAD what would happens with the existing FreeCAD if my new build breaks anything?

This switch only is relevant if you run "make install" or "sudo make install"
If you don't build the install project, and run FreeCAD from the bin directory of the build folder, all the builds are independent. They only share the common system libraries of the dependencies.
If you are building the install project you will want to change the install prefix so the new build doesn't overwrite the old one.

If you're testing builds, you don't necessarily need to run make install, unless you're specifically testing that port of the build process. Once you've done a cmake and make, you will have a FreeCAD binary at bin/FreeCAD inside your build folder. Unless you proceed to run make install the build results will never get copied anywhere and won't affect your existing FC installation. If you did run make install and didn't change your install prefix, it would overwrite the existing installation at that path.

oke summery for me
if i just use cmake and make i can use it locally(place of compiling)
and if i use cmake and make install i create some binary in usr/local/... etc (or wherever i want)

It looks that something has to do with the gui but i didn't change anything about that...
This was the cmake tekst

Code: Select all

cmake ../FreeCAD -DCMAKE_INSTALL_PREFIX:PATH=/opt/local/FreeCAD-0.17 -DBUILD_FEM_NETGEN=1  -DCMAKE_CXX_FLAGS="-DNETGEN_V5"  -DNETGEN_ROOT=/opt/local/FreeCAD-0.17  -DFREECAD_USE_OCC_VARIANT="Official Version"  -DOCC_INCLUDE_DIR=/opt/local/FreeCAD-0.17/include/opencascade  -DOCC_LIBRARY=/opt/local/FreeCAD-0.17/lib/libTKernel.so -DBUILD_VR=OFF -DBUILD_TECHDRAW=OFF -DBUILD_SPREADSHEET=OFF -DBUILD_SHIP=OFF -DBUILD_ROBOT=OFF -DBUILD_REVERSEENGINEERING=OFF -DBUILD_RAYTRACING=OFF -DBUILD_POINTS=OFF -DBUILD_PATH=OFF -DBUILD_OPENSCAD=OFF -DBUILD_IMAGE=OFF -DBUILD_ARCH=OFF

have anybody an idea?

[wmayer]

Your build logs only show that there is an error but none of the show the right location where the actual problem occurred. You should just run make without any further parameters (especially not -j) so that it hopefully stops where the build fails.

[Jee-Bee]

alse without -j i got some errors

Again on a different place... however i don need drawing at all... so i can remove it from compiling but i think it crash somewhere else
Edit i compile without spreadsheet... Are there more workbenches that need spreadsheet?

[Jee-Bee]

fixed It was a reference to an workbench i didn't had...
