Hi, I'm sorry to bug you guys with something this mundane. I've been
trying to get this working for two days and feel like I'm in a bit
over my head. I've managed to get it to compile and link, but when
running the library, I get this error:
lua: error loading module 'luagd' from file './luagd.so':
dlopen(./luagd.so, 2): Symbol not found: _gdFontGetGiant
Referenced from: /Users/mjudge/Downloads/lua-gd-2.0.33r2/luagd.so
Expected in: dynamic lookup
(Thanks for your help)
------------------------------------------------------------
Here's the log of steps I took to compile it:
Downloaded the lua source for 5.1.3, compiled via:
* make macosx
* sudo make install
Installed gd via macports:
* sudo port install gd2
Downloaded lua-gd-2.0.33r2 (for Lua 5.1), compiled via:
* gcc -O2 -fno-common -I/usr/local/include/ -I/opt/local/include/ -c
-o luagd.o luagd.c
luagd.c:2165: error: 'LgdImageCreateFromPng' undeclared here (not in
a function)
luagd.c:2166: error: 'LgdImageCreateFromPngPtr' undeclared here (not
in a function)
* Edited luagd.c to wrap those lines in an ifdef GD_PNG:
#ifdef GD_PNG
{ "createFromPng", LgdImageCreateFromPng },
{ "createFromPngStr", LgdImageCreateFromPngPtr },
#endif
* Recompiled
gcc -O2 -fno-common -I/usr/local/include/ -I/opt/local/include/ -c
-o luagd.o luagd.c
* Linked
gcc -bundle -undefined dynamic_lookup -Wl -bind_at_load -o luagd.so luagd.o
* Copied to my lua include path
sudo cp luagd.so /usr/local/lib/lua/5.1/
* Fired it up
lua -l luagd
lua: error loading module 'luagd' from file './luagd.so':
dlopen(./luagd.so, 2): Symbol not found: _gdFontGetGiant
