Hello: I followed Alberto Zin's instructions for compiling pd externals using Mingw and they worked OK. But: I modified de hello.c code adding the opening and closing of a file. Of course, the <stdio.h> header file must be added to the code. Attached to this message is the modified "hello.c". The code compiles Ok, and I get the hello.o using the following command line:
C:\pd\isidro\hello>gcc -c hello.c -o hello.o
But when I try to link to get the Dll file, I get the following message:
C:\pd\isidro\hello>ld -export_dynamic -shared -o hello.dll hello.o c:/pd/bin/pd.dll
hello.o(.text+0x16):hello.c: undefined reference to
fopen' hello.o(.text+0x30):hello.c: undefined reference tofclose'
The same I get if I use some Standard Library Function like <string.h> or other... Maybe I am doing something really stupid but if you know what's up it will save lots of time to me... Many thanks Isi
