2.5 Install libcurl for both 32bit and 64bit?
In curl's configure procedure one of the regular include files get created
with platform specific information. The file 'curl/curlbuild.h' in the
installed libcurl file tree is therefore somewhat tied to that particular
platform.
To allow applications to get built for either 32bit or 64bit you need to
install libcurl headers for both setups and unfortunately curl doesn't do
this automatically.
A commonly used procedure is this:
$ ./configure [32bit platform]
$ mv curl/curlbuild.h curl/curlbuild-32bit.h
$ ./configure [64bit platform]
$ mv curl/curlbuild.h curl/curlbuild-64bit.h
Then you make a toplevel curl/curlbuild.h replacement that only does this:
#ifdef IS_32BIT
#include "curlbuild-32bit.h"
else
#include "curlbuild-64bit.h"
#endif
