QUESTION
I compiled a object file shm.o
and packaged it as a shared library libshm.so
ANSWER
Answered 2021-Jun-04 at 15:39As it can see, at the second line to last, shm_open is a undefined symbol even though -lrt is appended.
This is expected: you are linking against librt.so
. The definition of shm_open
is in librt.so
, and not in your library.
What should be done to get this problem fixed?
There is no problem and there is nothing to fix here.

The simplest approach by far is to also add the AspectJ Weaver agent to the command line, i.e. to use something like (on a single line, of course)

I was mostly used to dll

extensions when using third-party libraries which I used to comfortably incorporate using Visual Studio in my Windows Environment.

Answered 2021-Apr-28 at 05:51Unfortunately in newer versions of make, load
is a special word and make fails when load
is used as a target. This is quite bad, actually, as it violates POSIX etc. There's a Savannah bug open about this. You can work around the issue by using a variable instead:
QUESTION
I was working on a project and I was trying to get an image to load so I could use it as a texture, but I ran into an issue when I tried to include stb_image.
I put stb_image.h
in src/vendor/stb_image/
, made a cpp file named stb_image.cpp

ANSWER
Answered 2021-Apr-24 at 17:43The file which contains the implementation of the stb methods (src/vendor/stb_image/stb_image.cpp
) is not part of your compilation as can be seen by checking which cpp files are mentioned in your build command.
The reason for this is that the cmake file is set up to only compile files in the src folder, but not files in the src/vendor/stb_image/
folder. You have to add those files in order to get the implementation of the library into your project.

Answered 2021-Apr-18 at 04:00In the functions insert_item()
and remove_item()
, returning (end of execution of the functions) happens before executing pthread_mutex_unlock()
. This will prevent them from unlocking and prevent 2nd or later execution of the functions.
Instead of this, you should store the value to return in a variable and return that after unlocking. This can be done like this:

Answered 2021-Apr-15 at 16:43how gcc compiler detect args parameter.
Gcc is a very old project with a lot of options. It has it's own command line options handling library.
The -lXrandr word is the name of the package you have installed
No, it's not the name of package. It's the name of the library.
What does the compiler do?
Compiler searches for a library name libXrandr.so
. In short, the file is searched in multiple directories, the standard library paths are searched and gcc installation path and additionally paths given with -L
parameter and paths with LIBRARY_PATH
environment variable. See also man ld.so and man ldconfig.
Does the compiler search for pre-specified folders
Yes.
and check for packages?
No, a "package" is something else. Gcc is a compiler, it does not deal with "packages".
how the cpp [*gcc] compiler connects files on the Linux system
"How" is a broad question and gcc is a very complicated program. It opens the files, parses them properly, finds symbols, resolves references, generates final executable.
Do you have any links to help with this knowledge?
Gcc has extensive documentation and it's open source.
