Hello,

I am new to the Boost mailing list so please let me know if this is not

I have successfully managed to compile several of the Boost libraries (regex, filesystem, thread) and create a framework for use with OS X, iOS, and the iOS simulator using this script: https://github.com/wuhao5/boost/blob/188e905626dbd522f65950102ed0c8ce77cb28e... boost.sh

the appropriate place to discuss my problem. based on Peter Goodliffe's work here: http://goodliffe.blogspot.com/2010/09/building-boost-framework-for-ios-iphon... with Boost 1.53.0 using clang and linking against libc++.

The script fails when compiling for the iOS simulator with Boost 1.54.0

with the following error:/bin/sh: line 1: -ftemplate-depth-128: command not found.

I did quite a bit of digging and here is what I know:    * In boost.sh,

the iOS simulator bjam and compiler options include "-arch i386"    * The release notes for Boost 1.54.0 state that "Boost no longer supports the 80386 target CPU"

    * The Boost 1.53.0 libraries mentioned above appear to compile fine

for OS X, iOS, and the iOS simulator using the same script    * The Boost 1.54.0 libraries appear to compile fine for OS X and iOS itself using the same script

Here is what I think I know:    * When passing "-d13" to bjam (to generate

debug information), it

appears that the variable "CONFIG_COMMAND" is not being set when building for the iOS simulator. For the other configurations, this variable is set to the path to clang and includes the compiler options. For the simulator, it is empty which I believe leads to the error above as when bjam attempts to run the compiler using this variable, it instead runs some appended options which begin with the template depth. Therefore, the CONFIG_COMMAND variable does not appear to be being set properly causing the failure.

I do not know why it's not being set as I don't know enough about the Boost build system to sift through the rest of the output generated with the "-d13" flag. I suspect an incompatibility with the "-arch i386" option was introduced with 1.54.0. I've tried changing this to "-arch i486" and "-arch x86_32" but the same problem occurs.

Has anyone else had success with this? I'd like to use Boost.Log which is why I'm even attempting this with 1.54.Thanks!

Hello. As there have been no replies to my post I'm wondering if a different approach is needed. I think digging into the bjam debug output can shed some light on the problem. Can anyone point me to the part of the process that populates the CONFIG_COMMAND variable? What is the recommended method to debug the bjam build process? Thanks!
