This is a followup to a previous question on cross-compiling for the iPhone:

Basically, I am trying to compile the Apache Portable Runtime (APR) version 1.3.8 (latest) for the iPhone. I am currently running into the following error during the configuration step:<\/p>\n
\nchecking for working PROCESS_SHARED locks... configure: error: in `\/Users\/michaelsafyan\/Downloads\/apr-1.3.8':\nconfigure: error: cannot run test program while cross compiling\nSee `config.log' for more details.\n<\/pre>\nI am invoking the “configure” script via “iphone3.1-configure –disable-dso –enable-threads”, where “iphone3.1-configure” is the following script that I’ve cooked-up to invoke the “configure” script:<\/p>\n

In fact, the “ac_cv_file__dev_zero=no” and “ac_cv_func_setpgrp_void=yes” elements in the “iphone3.1-configure” script cause two similarly failing tests to be bypassed. The problem I am having is that I do not know how to bypass this check — that is, I don’t know what variable(s) to set to bypass this test and any additional tests that try to run executables built for the target platform. I was able to bypass the earlier two similar tests simply because I was able to locate the workaround on Google… does anyone know what variables to set or another way to bypass this check?<\/p>\n
If anyone knows a way to suppress all tests that cannot be executed when cross-compiling, or if you just know how to suppress this specific check, I would be greatly appreciative. Thank you very much.<\/p>\n","protected":false},"excerpt":{"rendered":"
