[Solved]local build run starts global installed one

[bernd]

I try to explain what is happening here on a Debian Buster Linux. I have no idea why ...

I have the following build installed on /usr/local

Code: Select all

OS: Debian GNU/Linux 10 (buster) (KDE//usr/share/xsessions/plasma)
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.19.18527 (Git)
Build type: Unknown
Branch: master
Hash: 1f5f00e655b573489c3e897efd5d87e93cf77f15
Python version: 3.7.3
Qt version: 5.11.3
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: German/Switzerland (de_CH)

If this is started I get ...

Code: Select all

hugo@Ahorn:~$ FreeCAD
FreeCAD 0.19, Libs: 0.19R18527 (Git)
© Juergen Riegel, Werner Mayer, Yorik van Havre 2001-2019

everything with this is fine.

In my FreeCAD build directory I am at master head somewhere around 0.19.18559

$ git log -1

Code: Select all

    Fix auth base64 computation when HMAC return string contains \0 character

Building FreeCAD works fine but if I run in the Builddirectory by invoking

Code: Select all

./bin/FreeCAD 

it does not start the FreeCAD from build directory, it uses libs from usr local ...

Code: Select all

~/Documents/dev/freecad/freecadbhb_dev/build$ ./bin/FreeCAD
FreeCAD 0.19, Libs: 0.19R18527 (Git)

But it does not load all from /usr/local, just some parts. I have no idea which one. For sure all Python modules is taken from build directory. This is why I still can develop without installing

But if something bigger has changed I need to install FreeCAD to run it from build directory. This has for sure worked before. I allready did a rebuild. I have no idea where to look for a solution for this.

anyone has an idea how to debug or where to look.

Do you have set LD_LIBRARY_PATH or are the FreeCAD libs installed to a directory listed in ld.so.conf?
What does ldd <Path_to_an_so_file_in_your_build_dir> return?
Do you use the RPATH option?

aha this should not /usr/local/lib/ ...

but I did not set it environment variable. My Debian install is quite new. I did a reinstall after four years a few weeks ago (two or three)

ha I needed to set LD_LIBRARY_PATH for IFCPlusPlus ... https://gist.github.com/berndhahnebach/ ... lus-sh-L95

[bernd]

if I use export LD_LIBRARY_PATH=/opt/netgen/lib only it works great and IfcPlusPlus still runs fine ... May be it is no longer needed. May be someone fixed it in IFCPlusPlus cmake ...

Thanks very much werner. As quite often, I understood your post and what I did, but I would have never did it without your hints.

There are two ways to solve the problem:

1. The first you figured out by removing /usr/local/lib from LD_LIBRARY_PATH
2. The other way would be to adjust your cmake settings not to install FreeCAD libs directly to /usr/local/lib but into a sub-directory e.g. /usr/local/lib/freecad

another thanks for that one which is easy to but one need to know about
