Cross-compilation failure due to gen_test_char

Suppose the APR library is being compiled on a 32-bit host for a 64-bit targer. The compilation will fail, since the execution of the tool 'gen_test_char' is not possible because of cross-compilation.

My understanding is the tool needs to be compiled natively no matter what the target platform is.

Regards,
Arsen

Hi Günter,

I thought this is a new issue introduced in apr-1.5.0, but it turns out this functionality was passed along from httpd and the problem is most probably well-known to many of you.

Please note that not only GNU build is affected. This issue unfortunately needs to be addressed for each build system separately.

If someone asked me regarding a possible solution, I'd prefer to have 'apr_escape_test_char.h' pre-generated in the tree for all the operating systems under the 'arch' directory respectively. This would need to be done by the maintainer once in a while and seems to me much easier/cleaner than having 'gen_test_char' integrated into the common build routine.

Regards,
Arsen

correct - are you up to provide a patch to the configure script?
we need to do something with vars like CC_FOR_BUILD etc. - but 
unfortunately I'm not so fluent with configure scripts ;-)

BTW. we need same also for httpd - and I did at some time a
 new hack to 
configure which I wanted to discuss - but I cant find ATM ...

greets, Günter.
