Re: [Bug-apl] Cannot find libemacs on older mac

[Juergen Sauermann]

Hi Alexey,

I am not really familiar with emacs or OS X, so Elias is probably better informed than me.

Unfotunately shared libraries are rather platform dependent and so are the error messages that
they produce. From the output below it seems that the file libemacs.dylib exists and was found,
but could not be opened with dlopen(). It might be that your platform needs additional linker flags
for dynamic libraries to work, but I have no idea which ones.

Hi,

I've built GNU APL with the following parameters on my old  (OSX 10.6.8) macbook:

./configure --prefix=/Users/alexey/Applications/gnu-apl
make install

So nothing special(I did a small change though since strndup is not yet supported on this OS). I'm using gcc 7.2.0.

However when I try to run apl from emacs, I get the following error:

Could not find shared library 'libemacs'
The following directories and file names were tried:
    file /Users/alexey/Applications/gnu-apl/lib/apl/libemacs.so (No such file or directory)

The file /Users/alexey/Applications/gnu-apl/lib/apl/libemacs.dylib exists.
