local cross compile: example openssl version: 1.1.1b

(1) failed

  1. wget https://github.com/openssl/openssl/archive/OpenSSL_1_1_1b.tar.gz
  2. tar zxvf OpenSSL_1_1_1b.tar.gz
  3. ./config no-asm shared --prefix=/data/armlib/mqtt/openlib --cross-compile-prefix=aarch64-linux-gnu-
  4. make error log: 
    ...
aarch64-linux-gnu-gcc: error: unrecognized command line option '-m64'
make[1]: *** [Makefile:706: apps/app_rand.o] Error 1
...

    (2) modify, success

    before make, modify Makefile:

  5. vim ./Makefile, and delete all "-m64", in row 124, 125
  6. make
  7. make install

success!

the question is: how could I modify "-m64" config in my conanfile.py

from conan import ConanFile
from conan.tools.cmake import cmake_layout

class ExampleRecipe(ConanFile):
    settings = "os", "compiler", "build_type", "arch"
    generators = "CMakeDeps", "CMakeToolchain"

    def requirements(self):
        self.requires("openssl/3.2.1")

    def layout(self):
        cmake_layout(self)

notice:

-m64 is only valid for x86_64 processors, not arm64 processors.

For a workaround, see what @jakubablenski did here: https://github.com/conan-io/conan-center-index/issues/24122

Essentially: sudo apt install g++-[DESIRED_VERSION]-aarch64-linux-gnu, then edit CC/CXX/LD in your [buildenv]. Not sure if it works using only tools.build:compiler_executables.

Hi @renjiangithub thanks for reporting this.

Could you paste the full build log rather than just the last bit?

Thanks!
