I’m looking into adding some useful programs to my petalinux setup – like php support for example.
As I’m sure you know, most open source programs come with a neat ‘configure’ program which auto-detects what the system has/supports, mainly by running various tests with gcc.
This then generates the makefile(s) which are used to compile the program.
However, in the petalinux environment, any ‘configure’ operation would run on the build machine, so the makefile generated would not reflect the petalinux system capabalites.
So to make a long story short – has anyone come up with a general way of running configure / generating the makefile for open source programs?
Hand creating/hacking the makefile would be pretty tricky!
If one does not exist, a possible solution may be this:
As configure usually runs very similar ‘tests’ for most open source projects – I wonder could a list of the ‘answers’ to these tests be pre-calculated for petalinux, and then when configure checks for something, instead of getting what the build machine supports, it would instead return the pre-calculated result for the petalinux env. For any tests that do not have answers, these could be asked as questions to the user.
At least this would go someway to automating the process.
A case in point – I recently tried compiling the latest thttpd (2.25b), and ran into this issue. Ideally I’d like to get php working with that – but I’m starting to think that would be VERY wishful thinking….
I was able to get thttpd to compile, but I had to make some guesses as to some of the #defines that had to be set. The resulting binary seems to work for the most part, but never serves cgi scripts.
So I can only assume some of my guessed settings are incorrect.
This is not critical or anything, just looking to see if anyone has solved this generic building issue.
