[Buildroot] [PATCH v7 1/1] libcpprestsdk: new package

[Adam Duskett]

The C++ REST SDK is a Microsoft project for cloud-based client-server
communication in native code using a modern asynchronous C++ API design.
This project aims to help C++ developers connect to and interact with
services.

This package is licensed under the MIT package and depends on BOOST
and OpenSSL/LibreSSL.

Changes v1 -> v2:
  - Add "depends on BR2_USE_WCHAR # boost" to boost.mk (Thomas)
  - Remove "depends on BR2_USE_MMU" from boost.mk (Thomas)
  - Add "!BR2_USE_WCHAR" to boost.mk (Thomas)

Changes v2 -> v3:
  - Update to v2.10.0
  - Remove check for libressl now that OpenSSL is a virtual package.
  - Add 0001-remove-cast-align-error-flag.patch to prevent cross-compiling
    warning errors.
  - Add 0002-fix-xlocale-header-check.patch to prevent uclibc/musl errors
    due to a missing header.
  - Add 0003-fix-compilation-issues-with-musl.patch which adds sys/time.h to
    asyncrt_utils.h.

Changes v3 -> v4:
  - Fixed 0003-fix-compilation-issues-with-musl.patch
  
Changes v4 -> v5
  - Patches now formatted with -N.
  - Dependencies now on a single line.
  
Changes v5 -> v6
  - Removed 0001-remove-cast-align-error-flag.patch in favor of passing
    -DWERROR=OFF in libcpprestsdk.mk (Arnout)
  - Renamed fix-compilation-issues-with-musl.patch to 
    include-sys-time-for-struct-timeval.patch (Arnout)
  - Fixed spacing issues in Config.in
  - Fixed spacing issues in libcpprestsdk.hash (Arnout)

Changes v6 -> v7
  - Bump to version v2.10.1

As discussed on IRC, this fails to build with the following defconfig:

BR2_arm=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y
BR2_TOOLCHAIN_EXTERNAL_URL="http://autobuild.buildroot.org/toolchains/tarballs/br-arm-full-2017.11-rc1.tar.bz2"

It fails with:

Interestingly, it is the same error I had when building opentracing-cpp
with the same toolchain. Building with the Linaro ARM toolchain works
fine however.

Could you test this package with ./utils/test-pkg before submitting the
next version ?

Thanks!

So, at this point I always do.  Here are the results from what I normally run:

./utils/test-pkg -c configs/libcpprestsdk_defconfig -p libcpprestsdk
-t /home/adam/Documents/brtest/small_test.csv
                     min_glibc_defconfig [1/3]: OK
                      min_musl_defconfig [2/3]: OK
                    min_uclibc_defconfig [3/3]: OK
3 builds, 0 skipped, 0 build failed, 0 legal-info failed

This tells me that at least glibc, musl, and uclibc-ng all build
successfully.  I normally test with gcc 7.x, and the toolchain you
tested with is quite a bit older.

Thanks!

Since Jan Heylen had the same problem on opentracing-cpp, he
investigated it. It turns out that you need to make your package
"depends on !BR2_TOOLCHAIN_HAS_GCC_BUG_64735" to avoid a gcc bug.

Could you resubmit with this change ?

Thanks!
