How to fix Linux LD cannot find an existing library?

How to fix Linux LD cannot find an existing library?

As mentioned above the linker is looking for libmagic.so, but you only have libmagic.so.1. To solve this problem just perform an update cache. Unless I’m badly mistaken libmagic or -lmagic is not the same library as ImageMagick. You state that you want ImageMagick. ImageMagick comes with a utility to supply all appropriate options to the compiler.

Why do I need a linker for libmagic?

However, because the library is specified as -lmagic to the linker, it looks for libmagic.so, which is why it is needed for development. See Diego E. Pettenò: Linkers and names for details on how this all works on Linux.

Why does libz.so.1 say ” not found “?

Note “libz.so.1 => not found”. (I logged out and logged back in to be sure it was sticking.) Thank you, everyone, for pointing me in the correct direction. Thanks for contributing an answer to Stack Overflow!

What to do if library is not found in Ubuntu?

In Ubuntu, you can install libtool which resolves the libraries automatically. This resolved a problem with ltdl for me, which had been installed as libltdl.so.7 and wasn’t found as simply -lltdl in the make.

How to install libmagic Dev in Ubuntu Linux?

In short, you should apt-get install libmagic-dev. This will not only give you libmagic.so but also other files necessary for compiling like /usr/include/magic.h. In Ubuntu, you can install libtool which resolves the libraries automatically.

How can I generate a 32 bit binary from my 32 bit shared object?

I tried using flag -m32 or –32, but ld dont take them. I cannot find a solution by reading the man page of ld. How can I generate a 32-bit binary from my 32-bit shared object? Your linker is attempting to create a 64-bit binary, but your assembly code was assembled for a 32-bit architecture. This creates a mismatch.

Why is GCC / LD cannot find external library?

OS: Windows 7 Enterprise x64 IDE: Eclipse Juno/CDT Compiler: MinGW 4.6.2 (C:\\MinGW) Like user697111, I cannot get ld.exe to find an external library.

What does it mean when G + + says cannot find-L?

When g++ says cannot find -l , it means that g++ looked for the file lib {nameOfTheLibrary}.so, but it couldn’t find it in the shared library search path, which by default points to /usr/lib and /usr/local/lib and somewhere else maybe.

Where does dynamic linker look for a library?

In runtime your app (actually dynamic linker) looks for its libraries in LD_LIBRARY_PATH. It’s an environment variable which stores a list of paths. Example: In case of our libswift.so example, dynamic linker cannot find libswift.so in LD_LIBRARY_PATH (which points to default search paths).

Is the libmagic library the same as the ImageMagick library?

Unless I’m badly mistaken libmagic or -lmagic is not the same library as ImageMagick. You state that you want ImageMagick. ImageMagick comes with a utility to supply all appropriate options to the compiler. Installing libgl1-mesa-dev from the Ubuntu repo resolved this problem for me.
