Mar 03, 2017 We definitely need to figure out why those aren't loaded properly. Are you setting LDLIBRARYPATH in your startup scripts for your shell (.bashrc)? One annoyance on OS X is that it invokes Applications with launchctl and does not create a shell for you.
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.

System Integrity Protection is a security technology in OS X El Capitan and later that's designed to help prevent potentially malicious software from modifying protected files and folders on your Mac. System Integrity Protection restricts the root user account and limits the actions that the root user can perform on protected parts of the Mac operating system.
Mac os high sierra show library. Before System Integrity Protection, the root user had no permission restrictions, so it could access any system folder or app on your Mac. Software obtained root-level access when you entered your administrator name and password to install the software. That allowed the software to modify or overwrite any system file or app.
System Integrity Protection includes protection for these parts of the system:
Mac Os Ld_library_path Windows 7
- /System
- /usr
- /bin
- /sbin
- /var
- Apps that are pre-installed with OS X
Paths and apps that third-party apps and installers can continue to write to include:
- /Applications
- /Library
- /usr/local
System Integrity Protection is designed to allow modification of these protected parts only by processes that are signed by Apple and have special entitlements to write to system files, such as Apple software updates and Apple installers. Apps that you download from the Mac App Store already work with System Integrity Protection. Other third-party software, if it conflicts with System Integrity Protection, might be set aside when you upgrade to OS X El Capitan or later.
System Integrity Protection also helps prevent software from selecting a startup disk. To select a startup disk, choose System Preferences from the Apple menu, then click Startup Disk. Or hold down the Option key while you restart, then choose from the list of startup disks.
