5 Setting environment variables. On Windows, TOMLAB requires the directory tomlab/shared to be included in the environment variable PATH. On Linux, TOMLAB requires the tomlab/shared folder to be present in the LDLIBRARYPATH environment variable. Feb 08, 2006 long double with MATLAB? Thread starter boyfarrell. I have GMP installed on the Mac for my C apps but I didn't know about the matlab link, cheers I'll give it ago. I don't think my LDLIBRARYPATH is set propertly. Where do I set this? The LDLIBRARYPATH in xterm says /opt/local/include shouldn't it be /opt/local/lib as I want to.
5 Setting environment variables
Set the system library path. This is the path that the operating system will search whenever it needs to find a shared library that it doesn't already know the location of. It is not Java-, NetCDF-, or CDM-specific. As usual, details will vary with each platform. The system library path maps to the LDLIBRARYPATH environment variable. Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Steps 2 and 3 describe the compile process under Windows. Similar steps are required for Mac OS X or Linux. In the MLMatlabScriptWrapper.pro file, the path to the Matlab libraries must be set. For this, you will need to locate the required Matlab.lib files.
On Windows, TOMLAB requires the directory tomlab/shared to be included in the environment variable PATH.
On Linux, TOMLAB requires the tomlab/shared folder to be present in the LD_LIBRARY_PATH environment variable. If TOMLAB is installed with super-user privileges on Linux, the installer will add a ldconfig entry to /etc/ld.so.conf.d/tomlab.conf, eliminating the need for manual manipulation of LD_LIBRARY_PATH.
It is possible to set this in several ways.
5.1 Shared libraries path
The library search path environment variable name differs betweendifferent systems:
- Linux: LD_LIBRARY_PATH
- Windows: PATH
TOMLAB for Mac OS X does not currently require the corresponding variable to be set, due to all binaries having hard-coded paths to their respective dependencies. This, on the other hand, demands that binary files in the TOMLAB directory are not moved from their locations.
The way environment variables are set varies depending on operating systems and shells.
5.1.1 Windows
To set the PATH environment variable permanently on Windows,do: Control Panel → System → Advanced→ Environment Variables. Assuming TOMLAB was installedin C:tomlab, append (or prepend) C:tomlabshared separated to the otherentries with a semi-colon (;) to the PATH environmentvariable.
The PATH environment variable can also be set temporarily ina running command shell. This is done by doing
This change will only be applied in that command shell, and willtherefore be discarded when the command shell is terminated.
5.1.2 Linux systems
Set on command line when invoking MATLAB:
where <ml> is the name of your MATLAB executable andtpath is the TOMLAB installation path. If LD_LIBRARY_PATHis already set to something and you wish to preserve this, includethe part in [ ] - but not the actual brackets themselves.
Set in $HOME/.bashrc, $HOME/.profile, $HOME/.cshrc (or$HOME/.matlab7rc.sh if it exists):
If you have an existing value in LD_LIBRARY_PATH, use a colon : toseparate directories when adding the TOMLAB directory:
Export Ld Library Path
If installing for multiple users as super-user, /etc/ld.so.conf.d/tomlab.conf is automatically created, eliminating the need for path manipulation.
This folder can run quite large just because so many apps cache something in there. If the cache /Library/Caches folder is over 3Gb then you have something that is caching quite a lot. On the three machines I just checked none had a /Library/Caches folder over. Mac library caches.
Mac OS X installations do not require the corresponding variable DYLD_LIBRARY_PATH to be set, but proper function depends on the locationof the tomlab/shared folder and its contents.
5.1.3 MATLAB 7.8+ on 64-bit Linux
A potential problem concerning shared library versions may lead to crashes when running certain TOMLAB MEX files.This is related to MATLAB and/or the runtime linker loading the wrong version of a support library.
The following workaround is suggested:
Start Matlab 7.8+ from a shell prompt with the following option:
Ld Library Path Linux
In the above command, replace $TOMLAB with the path to your TOMLABinstallation, and $MATLAB78 with the name of your MATLAB 7.8binary. This may vary depending on your particular setup, e.g. ifhaving a symbolic link to the MATLAB binary or not. You may need tospecify the full path to the MATLAB installation. For example:

Additionally, if using the KNITRO solver and you experience errors about libgomp.sonot being found, add an LD_PRELOAD statement for this library too. Use locate or find to find its full path. It is not supplied with TOMLAB.
