Unable to set DYLDFALLBACKLIBRARYPATH in shell on OSX 10.11.1. Ask Question. If they try for anywhere else under /usr I would question the author's knowledge of OS X. (LDLIBRARYPATH) weirdly hidden under bash on Mac. Dyld monitors DYLD variables behind the scenes. Set LDLIBRARYPATH for applications started from the desktop.

When I launch Qt Creator from the desktop I can build the application I. In computing, a dynamic linker is the part of an operating system that loads and links the shared libraries needed by an executable when it is executed (at 'run time'), by copying the content of libraries from persistent storage to RAM, filling jump tables and relocating pointers. OS X terminal runs a login shell, and so the start up file may be /.bashrc, /.bashprofile, /.bashlogin, or /.profile. See the manpage for Bash for more information about the differences between login and non-login shells. Modify and export PATH, PYTHONPATH, and (if using a Dakota release prior to 6.8) (DY)LDLIBRARYPATH variables.

5 Setting environment variables

This document is a Mac OS X manual page. Manual pages are a command-line technology for providing documentation. You can view these manual pages locally using the man(1) command. These manual pages come from many different sources, and thus, have a variety of writing styles. In shell scripts used for unit testing with dynamic libraries in a directory other than the typical @rpath, I have previously been able to set DYLDFALLBACKLIBRARYPATH to set the directory containing the libraries. Under 10.11.1, bash seems to ignore attempts to set this environment variable. Hello everybody! Today I'm trying to install php module of SQL Anywhere on MAMP for Mac OS X. I'm currently on Mac OS X 10.10 Yosemite, MAMP 3.0.7.1, php 5.5.17 and SQLAnywhere 16 Developer Edition.

On Windows, TOMLAB requires the directory tomlab/shared to be included in the environment variable PATH.

Mac

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 Ld_library_path Mac Os

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:

If installing for multiple users as super-user, /etc/ld.so.conf.d/tomlab.conf is automatically created, eliminating the need for path manipulation.

Mac Os Versions

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:

Windows Ld Library Path

Start Matlab 7.8+ from a shell prompt with the following option:

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.

Hi,
I am using g++ 3.3 on os X 10.3.9. I have created my own library
using
ar ruv *.o files
After this I try to compile a test program using,
g++ -pg -O -Wno-deprecated -ansi -pedantic -o test test.C
-DANSI_HEADERS -D_G_HAVE_BOOL -I. -I/ALLINCLUDEDIRS -lmylib -llpsolve51
-lm -L.
And the compilation works fine.
But when i try to run the executable ./test, I get the following error
message:
dyld: ./test_grid can't open library: liblpsolve51.dylib (No such file
or directory, errno = 2)
Trace/BPT trap
The library liblpsolve.dylib is NOT located in the current directory. I tried checking the value of LD_LIBRARY_PATH using echo$LD_LIBRARY_PATH, but nothing showed up.
It seems that LD_LIBRARY_PATH is not set, and moreover I am not even sure if it is used on darwin? On posting to a newsgroup, I was told that I need DYLD_LIBRARY_PATH instead. On doing echo $DYLD_LIBRARY_PATH I do not see any paths. Isn't a default value set for them already?
How can I resolve this problem?
thanks,
amit.
