Boost build script for iOS (armv7, armv7s, arm64), iOS Simulator (i386, x86_64), and OSX (i386, x86_64)

readme

-- 2016-05-18 UPDATE --
ATTENTION:
I have moved this script to an actual github repository. This will allow you all to create issues, make requests,
etc., without me having to remember to check this gist. It also means I will get emails when issues / questions are created.
It will also make it easier (hopefully) to track versioning.

The latest version there has been updated to build for tvOS (along with some other changes).

The new repository is located here:
https://github.com/faithfracture/Apple-Boost-BuildScript




-- 2015-09-22 UPDATE --
Added command line args!
You can now specify if you want to build just for iOS or OS X, along with some other things.
Run boost.sh -h for more info.
Let me know if there are any other parameters that you think would be useful.

-- 2015-09-18 UPDATE --
Fixed script for iOS Simulator (Thanks @XMitja!)
• There is now a MIN_IOS_VERSION variable. Make sure you set this appropriately.

cleanup function now actually removes all build artifacts

Fixed updateBoost function to move the existing user-config.jam instead 
of copying it. Copying it resulted in writing duplicate entries each time 
the script was run.

NOTE: Currently does not build with bitcode. I will figure that one out when I get time. 
I'm at the cusp of a product release though, so it might be a little while. 
Just disable bitcode for your project for the time being.

-- 2015-08-26 UPDATE --
The resulting libraries from this script are currently not working for
the iOS simulator under Xcode 7 as of beta 6. I have an issue opened
with Apple about this. It does still work for physical devices though.
As soon as I figure out what the problem is, I will post an update.

-- 2014-12-29 UPDATE --

Updated to work with Boost 1.56, 1.57, and 1.58

Automatically choose the currently selected SDK for both iOS and OSX

Fixed a couple places where the wrong $XXX_DEV_CMD was being used

-- END UPDATE --

This is a modified version of Pete Goodliffe's original boost.sh build script,
(and a couple of other sources whom I can't remember)

The original version didn't work with the 64-bit iPhone Simulator,
and didn't build at all for OSX.

This works for Boost 1.56 and 1.57. If you need the version that builds 1.55 and older, use this revision:
  https://gist.github.com/faithfracture/c629ae4c7168216a9856/61be257e1c0839c85743777d0687becad9913bf7

I also ran into an issue where utf8_codecvt_facet.o existed in both the 
program_options and filesystem libraries. When linking against the
framework, there was a missing vtable entry for it. Adding the step
in unpackArchive() that prepends the library name to the .o files
prevents this error.

I hope this keeps at least one other person from ripping their hair out.

Let me know if you find errors or have optimizations.

I will be updating this as often as necessary.

# Builds a Boost framework for iOS, iOS Simulator, and OSX.
# Creates a set of universal libraries that can be used on an iOS and in the
# iOS simulator. Then creates a pseudo-framework to make using boost in Xcode
# less painful.
#
# To configure the script, define:
#    BOOST_VERSION:   Which version of Boost to build (e.g. 1.58.0)
#    BOOST_VERSION2:  Same as BOOST_VERSION, but with _ instead of . (e.g. 1_58_0)
#    BOOST_LIBS:      Which Boost libraries to build
#    MIN_IOS_VERSION: Minimum iOS Target Version (e.g. 8.0)
#    IOS_SDK_VERSION: iOS SDK version (e.g. 9.0)
#    OSX_SDK_VERSION: OSX SDK version (e.g. 10.11)
#
# If a boost tarball does not exist in the current directory, this script will
# attempt to download the version specified by BOOST_VERSION. You may also
# manually place a matching tarball in the current directory and the script
# will use that.

OMG! Thanks @XMitja!

Many Thanks for your effort, but I've tried to build boost using boost.sh
and I got those errors :

http://pastebin.com/deM1QKZT

and it's the same for building for IOSsimulator and OSX as well

@amesh90 It says there's a syntax error in user-config.jam at keyword | (I assume that's a pipe?) The entire user-config.jam is written in the updateBoost() function, and there is no pipe in there, so I don't know where that's coming from. There are some macros that get expanded there, so it might have something to do with your $PATH. Can you paste the entire contents of /Users/arlab/ros_for_ios/boostonios/src/boost_1_58_0/tools/build/src/user-config.jam ?

@faithfracture here is the content of user-config.jam

http://pastebin.com/iFZft5rN

it contains pipe operator |
and I don't know where should I investigate the problem

Ok, I see a couple problems:

1 - I've had problems when the path contained a space. Your Xcode app has a space in its name: "Xcode 3.app". I would try renaming this to remove the space (Xcode3.app or Xcode_3.app or something like that).

2 - Are you really using Xcode 3? If so, I don't know how you're getting the iOS 8.1 SDK. Something might be awry with your Xcode installation.

3 - I think the root of the issue is that the command to find your OS X SDK version is not evaluating correctly. (the 3rd 'using darwin' statement) What happens if you run the command

xcodebuild -showsdks | grep macosx | egrep "[[:digit:]]+.[[:digit:]]+" -o | tail -1

directly from a command prompt? It should evaluate to '10.10' or something like that.

If you do not need Boost built for OS X, you can remove that part of the build process.
Try this: http://pastebin.com/Tf6yhQkb

This is golden - thanks @faithfracture!

Another improvement could be to add bitcode support. Which I believe is as simple as adding -fembed-bitcode to the EXTRA_CPPFLAGS. I will give this a shot and let you know.

@wtsnz - Thanks :) I've been wanting to add CLI args for quite a while. I got really really tired of commenting & uncommenting stuff, so I finally made some free time to do it.
Regarding bitcode support, I did try adding that flag, but I got an error about enabling bitcode and having multiple architectures defined at the same time, so the build command will have to be split out individually for each arch I think. I didn't have time to dig into it, so if you get it working let me know and I'll add it.

@faithfracture I notice that when I provide --boost-version 1.55.0 the BOOST_SRC printed is still src/boost_1_58_0.

Infact after downloading the tarsal it then fails with Aborted: Source tarball missing.

@faithfracture I've fixed that bug on my fork (see https://gist.github.com/mhaylock/2889d081525e589c7cae). 1.55.0 still doesn't compile (too old?) but 1.57.0 specified from the command line compiled fine after my fix.

Ah, good catch. I'll update this script with that.

Boost 1.55.0 used a different directory structure, so you can't build it with this script without some modification. I think all you need to do is change the lines in updateBoost() from:

mv $BOOST_SRC/tools/build/src/user-config.jam $BOOST_SRC/tools/build/src/user-config.jam-bk
...
cat >> $BOOST_SRC/tools/build/src/user-config.jam <<EOF
...
cat >> $BOOST_SRC/tools/build/src/user-config.jam <<EOF

to

mv $BOOST_SRC/tools/build/v2/user-config.jam $BOOST_SRC/tools/build/src/user-config.jam-bk
...
cat >> $BOOST_SRC/tools/build/v2/user-config.jam <<EOF
...
cat >> $BOOST_SRC/tools/build/v2/user-config.jam <<EOF

(short: change build/src to build/v2)

There might be more things that need changing, but I don't recall for sure. The original version of this script that I uploaded was originally for building Boost 1.55.0, so you might check the revisions. If I remember correctly, there was a problem with building for 64-bit iOS (I don't remember if it was for the simulator or arm64 or both). There was a patch file that we had to download from the Boost developer forum and manually patch the source.

Don't suppose anyone has attempted to do a similar build for tvOS or watchOS? Trying to publish to an AppleTV with the framework generated with this script results in a linker error (ld: in (path)/ios/framework/boost.framework/boost(thread_thread.o), building for tvOS, but linking in object file built for iOS, for architecture arm64)

Here is an alternate script for tvOS if anyone is looking for it:

Hi - Thanks for sharing this script !

I am trying to use http://www.codeproject.com/Articles/692787/Best-fitting-line-circle-and-ellipse for iOS. I modified it to not use program_options.

So the only library it needs is ublas which doesn't need to be compiled. The program compiles and runs great in OS X with stock 1.60.0 even without this script

But with iOS, i get the following error. I am using this script with 1.58.0. I am including the directory ios/prefix/include

Any help would be greatly appreciated

It seems including boost before including any other headers resolved the issue. I don't know why

This doesn't seem to work when trying to build boost.locale with ICU.

icu install is in /usr/local

bootstraps and builds just fine with "./boostrap --with-icu=/usr/local;./b2 --with-locale -sICU_PATH=/usr/local stage"

using the script I just get the "Boost.Locale needs either iconv or ICU library to be built." error.

Passing "-I/usr/local/include -I/usr/local/include -L/usr/local/lib" to user-config.jam inside the updateBoost function and adding --with-locale -sICU_PATH=/usr/local to the ./b2 commandline in buildBoost function doesn't fix the issue.

Anybody see the issue?

Couple things:

1. What parameters (if any) are you running the script with?
2. Are you using the correct version of the script? This version of the script doesn't work with versions of boost prior to 1.56.
3. Do you have the iOS 7.1 SDK installed?
4. What is the output you get at the very beginning when you run the script?
   It should look something like this:

I used this script to compile iOS & OSX framework. Everything compiled fine. OS X version works fine, but iOS version crashes in simulator, specially if I use a separate thread for async tcp client.

boost::thread bt(boost::bind(&boost::asio::io_service::run, &io_service)); cause it to crash in
boost::asio::async_read_until(socket_, input_buffer_, '\n', boost::bind(&TCPSocketClient::handle_read, this, _1));. However if I don't use thread and instead call io_service.run() to keep it in main thread itself, it works fine without any crash.

I tried searching for crash and somewhere read that it could be due to wrong compiler argument or different compilers. Any help?

I use async_read_until in my own project and I do not have this issue. If it is a bad compiler argument, I don't know what it would be. The settings in this script are exactly the ones I use to build boost for myself. I'd need a lot more information to help troubleshoot this. Sorry.

Seems like I can't build with the option BOOST_LIBS="asio system". I get this message, among others;

error: wrong library name 'asio' in the --with- option.

In response to EspenNaess, BOOST_LIBS can't reference header only "libraries", since there isn't a library to create for those. So BOOST_LIBS="asio system" can't figure out what to create for asio, because there is no asio library to create.

I'm also trying to compile "locale" for iOS (but with iconv) and the problem seems to be that all of the "detection" modes do not work. If one adds locale to the list of libraries that shall be compiled, runs it and then checks iphone-build/boost/bin.v2/config.log one find's that boost tries to compile has_iconv.cpp (and some other test programs) and fails to compile it NOT because iconv isn't available but BECAUSE something removes the compiler path & name and it tries to execute "-ftemplate-depth-128 ..." (so only the parameters). My guess is it has to do with adding the entries into the user-config.jam but I have spent a couple of hours and couldn't really figure out the syntax... anyone got an idea?

This detection-compilation-problem exists in all other (older) variants of this script that I found...

ATTENTION:
I have moved this script to an actual github repository. This will allow you all to create issues, make requests,
etc., without me having to remember to check this gist. It also means I will get emails when issues / questions are created.
It will also make it easier (hopefully) to track versioning.

The latest version there has been updated to build for tvOS (along with some other changes).

The new repository is located here:
https://github.com/faithfracture/Apple-Boost-BuildScript

thanks a lot!

Just to help and save other developers time

I've made a repository which contains Boost and OpenSSL built and ready for iOS and macOS architectures.

Includes thread-safe libraries aswell!
