Lambdanative can compile for OSX but not iOS

Question

I'm running Sierra with XCode 8.3 including command line tools. I can use Gambit to compile to OSX native code. I can use lambdanative to compile the test Calculator app to OSX but when I try to configure and then compile for iOS I get the following error in verbose mode:

checking whether the C compiler works... no
configure: error: in `/Users/querist/.lambdanative/tmp_install/gambc-v4_7_9':
configure: error: C compiler cannot create executables
See `config.log' for more details
ERROR: failed with exit code 77

There is no config.log to read. I've done a search for it and there is not one related to this project.

Any ideas? I really like the idea of being able to develop iOS apps in Scheme.

Thanks.

I realize this may be too late, but in case somebody else stumbles upon this, I though I'd try to explain.

config.log is placed in the library output directory, not your working folder. You can look for it by running find ~/Library/ -name 'config.log'.

In my case, config.log revealed the problem is that it can't find some version of a crt library. This problem is addressed here.

I edited my ./SETUP file from my lamdbanative working directory folder, so that IOSVERSION went from the 5.1.1 default to 6.0. That solved the problem for me.
