Re: Building emacs errors: libraries present

[Tory S. Anderson]

Okay; I'm making progress. I have identical problems with both 24.4 and 25.0.5 
build processes now. LibPNG is being found! But the gif library is not. In 
summary, I get NO configure errors (as long as I do sudo configure), but I get 
the following make error (even with sudo make, which I know is probably a 
dangerous command):

    ./temacs: error while loading shared libraries: libgif.so.7: cannot open 
shared object file: No such file or directory

But a find locates it just fine: 

    $ sudo find / -name "libgif.so.7"
    /usr/local/lib/libgif.so.7

Indeed, configure apparently found it, right? 

Unabridged config and make outputs for those interested:

Any ideas why it can't find libgif?
