I am thinking of writing a few PD externals, and so decided to try the
HOW-TO tutorial at http://iem.kug.ac.at/pd/externals-HOWTO/node1.html.
I am using gcc 3.3.3. m_pd.h is version 0.37 and is in /usr/include.
The problem is that if I simply copy and paste the helloworld code into
a text editor and try to compile with something like:
gcc helloworld_pd.c -o helloworld.pd_linux -l/usr/include
It fails with the wollowing output:
In function `_start':
: undefined reference to `main'
/tmp/ccWU3J7M.o(.text+0xf): In function `helloworld_bang':
: undefined reference to `post'
/tmp/ccWU3J7M.o(.text+0x28): In function `helloworld_new':
: undefined reference to `pd_new'
/tmp/ccWU3J7M.o(.text+0x53): In function `helloworld_setup':
: undefined reference to `gensym'
/tmp/ccWU3J7M.o(.text+0x5c): In function `helloworld_setup':
: undefined reference to `class_new'
/tmp/ccWU3J7M.o(.text+0x77): In function `helloworld_setup':
: undefined reference to `class_addbang'
collect2: ld returned 1 exit status
I apologise in advance if this question has already been answered - I
couldn't find anything in the mail archives...
Any help would be appreciated.
