dyld: Symbol not found: _AG_GL_BackupSurfaces

[TonalidadeHidrica]

I installed libagar into my Mac Mojave by the following steps, according to the official guide.

First, I installed SDL1.2 . (I don't know it's needed though)

$ brew install sdl

Next, I executed the following:

$ tar -xzf agar-1.5.0.tar.gz
$ cd agar-1.5.0.tar.gz
$ ./configure --prefix=$HOME/lib/agar
$ make depend all
$ make install

Then I created a file named hello.c according to the bottom of the page. I successfully compiled it, but when I try running, an dynamic library loading error occurs:

$ cc -o hello (~/lib/agar/bin/agar-config --cflags | string split " ") hello.c (~/lib/agar/bin/agar-config --libs | string split " ")
$ ./hello
dyld: Symbol not found: _AG_GL_BackupSurfaces

  Expected in: flat namespace
 in /Users/$USER/lib/agar//lib/libag_gui.5.dylib
fish: './hello' terminated by signal SIGABRT (Abort)

(where $USER is actually the username of my PC.)

What am I getting wrong? How can I fix this problem?

A sloppy attempt of adding DYLD_LIBRARY_PATH also failed.

$ export DYLD_LIBRARY_PATH=/Users/seasellsheshell/lib/agar/bin/:/Users/seasellsheshell/lib/agar/share/
$ ./hello

Can you post the contents of config.log from the build directory? I suspect the test for OpenGL has failed for some reason, and your build is missing OpenGL support as a result.

Enabling SDL support adds support for the "sdlgl" and "sdlfb" drivers. This allows Agar applications to run in SDL/OpenGL or SDL/Framebuffer mode in addition to the native "cocoa" driver (which uses the Cocoa API). The "sdlgl" driver is also handy if you wish to provide a MDI or "single-window" mode in a multi-window application.

Can you try again with version 1.6.0? (http://libagar.org/download.html) and please re-open the issue if the problem persists.
