Build openssl for emscripten #6884

3d4m-volodymyr · 2021-08-16T16:16:29Z

Made few changes which make it possible to build OpenSSL for Emsccripten very easy.

Emscripten installed as per manual on official website emscripten.org.
Emscripten activated in terminal/console and using custom profile below.

[settings]
os=Emscripten
arch=wasm
compiler=emcc
compiler.version=2.0.13
compiler.libcxx=libc++
build_type=Release
[options]

[env]
CONAN_CMAKE_FIND_ROOT_PATH=$EMSDK/upstream/emscripten/system
CONAN_CMAKE_TOOLCHAIN_FILE=$EMSDK/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake
CC="emcc"
AR="emar"
RANLIB="emranlib"

the command used to build library
conan create . openssl/1.1.1k@ -pr emsdk_profile

I've read the guidelines for contributing.
I've followed the PEP8 style guides for Python code in the recipes.
I've used the latest Conan client version.
I've tried at least one configuration locally with the
conan-center hook activated.

…patible.

+               "no_stdio": [True, False],
+               "no_tests": [True, False],


You need to add default values to default_options as well.

Nevermind. Openssl does this with a loop.

recipes/openssl/1.x.x/conanfile.py

+            self.options.no_asm = True
+            self.options.no_deprecated = True
+            self.options.no_dso = True
+            self.options.no_threads = True
+            self.options.no_stdio = True
+            self.options.no_tests = True


This makes it still possible to run:

conan create . openssl/1.1.1k@ -pr emsdk_profile -o openssl:no_stdio=False

Should this also be tested in a validate method?

def validate(self): if self.settings.or == "Emscripten": if not all((self.options.no_asm, self.options.no_deprecated, self.options.no_dso, self.options.no_threads, self.options.no_stdio, self.options.no_tests)): raise ConanInvalidConfiguration("os=Emscripten requires openssl:{no_asm,no_deprecated,no_dso,no_threads,no_stdio,no_tests}=True")

thanks, I will add this check

I'm wondering whether the test should be self.settings.os == "Emscripten" or self.settings.arch == "wasm".

Does my suggestion actually work? Does it block -o openssl:no_asm=False? I didn't verify locally.

this is good question! But idk any other sdks that are capable of compiling that complicated code to wasm.

Does my suggestion actually work? Does it block -o openssl:no_asm=False? I didn't verify locally.

yes it does

+                raise ConanInvalidConfiguration("os=Emscripten requires openssl:{no_asm,,no_threads,no_stdio,no_tests}=True")


Suggested change

raise ConanInvalidConfiguration("os=Emscripten requires openssl:{no_asm,,no_threads,no_stdio,no_tests}=True")

raise ConanInvalidConfiguration("os=Emscripten requires openssl:{no_asm,no_threads,no_stdio,no_tests}=True")

3d4m-volodymyr · 2021-08-18T18:14:00Z

@madebr I removed few things that are not necessary for Emscripten. Do you have an idea why the build failed?

madebr · 2021-08-18T18:19:14Z

It's an internal c3i error. Probably something timed out.
Try closing, waiting 10 secons, and re-opening this pr.

https://github.com/openssl/openssl/blob/1b495200436b57309ca958a7a72affaf75171c1a/INSTALL.md#no-algorithm * openssl/3.x.x: Remove legacy target names * openssl/3.x.x.: Remove more legacy conditions * openssl/3.x.x: Fix zlib option name * Revert "openssl/3.x.x: Update license to Apache-2.0" This reverts commit 13852ab1da9678d3700440bee862561af7878b37. * openssl/3.x.x: Actually update license to Apache-2.0 * openssl/3.x.x.: Remove all legacy version switches * openssl/3.x.x: Use OpenSSL_version instead of legacy SSLeay_version * openssl/3.x.x.: update test_package to never use find_package() Several reasons for this decision: 1) No matter the value of the paramter use_find_package CMake did always use a FindOpenSSL.cmake file 2) On my machine that meant that CMake used a FindOpenSSL.cmake file from my Python installation, which can't yet handle version 3.0.0 due to a regex error 3) Even when I addded the Conan cmake_find_package generator, it did not work (more cpp_info work needed, maybe?) 4) Even when 3) would be fixed, it would still always use the FindOpenSSL.cmake approach for some reason (I guess), so the entire use_find_package switch is pointless * openssl/3.x.x.: Remove custom OpenSSLVersion object * openssl/3.x.x.: Remove legacy target_prefix * openssl/3.x.x.: Remove custom _cross_building method Since tools.cross_building() has now a skip_x64_x86 flag * openssl/3.x.x: Some formatting * openssl/3.x.x: Remove old workaround for MinGW This got fixed in the meantime via openssl/openssl@9694ebf See also openssl/openssl#7653 * openssl/3.x.x: add no_engine option * openssl/3.x.x: Add 3.0.0-alpha5 * openssl/3.x.x: Port #1782 from @syoliver - add components * openssl/3.x.x: Fix license test The LICENSE file got renamed to LICENSE.txt * openssl/3.x.x: add old/ URLs as mirrors * openssl/3.x.x: threat URLs explicit as strings * openssl/3.x.x: add 3.0.0-alpha6 * openssl/3.x.x: the downloads have permament locations now This seems to be the case for a while now, but not for all old versions we support in the recipe for the 1.x.x versions It also does not seem to apply for pre-release versions, which rather seem to get de-published See also here:
