GMP and MPFR compile for iOS

readme

First need run build_gmp.sh then build_mpfr.sh

./build_gmp.sh -ios --min-ios-version 10.0
./build_mpfr.sh -ios --min-ios-version 10.0

./build_gmp.sh -osx --min-macosx-version 10.14
./build_mpfr.sh -osx --min-macosx-version 10.14

echo "Done with MPFR!"

Thanks for the great script!

Note: I found that this script produced a gmp library that did not work with iPhone 5s and later (both physical devices and simulators) because of the switch to x86_64 architecture for iPhone 5s and higher. Although the script does compile a library for the x86_64 architecture and include that library in the universal binary it produces, the x86_64 library it produces is tagged for the OSX platform rather than the iPhoneOS platform (see this post). If you try to link against it in Xcode when building for iPhone 5s or 5s simulator or higher, you get a "building for iOS simulator, but linking in object file built for OSX, for architecture x86_64" error. The solution I found was to replace line 92 of the script with:

build "x84_64" "${IPHONESIMULATOR_SDK}" "${IPHONESIMULATOR_PLATFORM}"

I also changed all of the author's other references to "x64_86" with "x86_64." Not sure that that makes a difference, but I thought it was a typo.

After making this change I was able to link against the fat binary produced by this script with iPhone 5 and 6 Plus hardware and all simulators.

This script is clutch. Thanks so much!

GMP script work fine with the ivme corrections.
MPFR script need a path without whitespace (example: /users/Documents/my projects/mprf)

Awesome stuff. Exactly what I needed.

@nijindal If you was thinking get some attention, you need mention name.

@ivme it's actually producing different arch armv7 and arm64 included in one lib. Maybe script is old for now.
Will see if I can share newer version.

thanks guys :)

Awesome script, thank you very much!
One note though, it seems that the mpfr script doesn't use BITCODE variable in the CFLAGS, while gmp does.

@sakrist thanks for the great script. Just want I need

@ivme thanks for the fix. It make sense.

Does any one got error after uploading the app to app store? I have a super simple app with the lib embed in the project. When I upload the app with "Include BitCode" checked to the app store, I got an email from app store like below:

We have discovered one or more issues with your recent delivery for "Stage". To process your delivery, the following issues must be corrected:

Invalid Bundle - The app cannot be processed because options not allowed to be embedded in bitcode are detected in the submission. It is likely that you are not building the app with the toolchain provided in Xcode. Rebuild your entire app with the latest GM Xcode and submit the app again.

If I have "Include BitCode" unchecked, then it will be fine.

My build env is iOS SDK 10.3, Xcode 8.3.3. With latest Mac OS X 10.12.6

I create a sample project here (the testGMPLibOnly branch): https://github.com/zwang/TestFactorize/tree/testGMPLibOnly

Thank you in advance for any help.

Hey, @zwang! Have you solved the issue with bitcode? I'm facing the same issue

@zwang, @podkovyrin, Have you found a solution for bitcode error?

@DmitrySmolyakov I had, take a look at the prepare command in the following podspec:
https://github.com/dashevo/dashsync-iOS/blob/master/bls-signatures-pod/bls-signatures-pod.podspec

@podkovyrin Thank you! I will take a look

@sakrist thanks for the script . Looks awesome but I'm not able to generate GMP for iOS:

I tried to fix it without success... Can you take a look, please?

 Thank you, my good man!

Anyone has a hint to use it on AppleSilicon: I get the error:
Building for iOS Simulator, but the linked library 'libgmp.a' was built for iOS.
