Hi,
I'm trying to build a complicated package for 32-bits on 64-bit Ubuntu.
I got very far using
set(CMAKE_C_FLAGS -m32)
set(CMAKE_LIBRARY_ARCHITECTURE i386-linux-gnu)
But right now, find_package(OpenSSL) is failing. I think the problem is
with FindOpenSSL.cmake doing this (Ubuntu 18.04, CMake 3.10):
if (UNIX)
find_package(PkgConfig QUIET)
pkg_check_modules(_OPENSSL QUIET openssl)
endif ()
Ubuntu has, I think compatibe with the Linux standard, these .pc files
for the multilib installed OpenSSL:
$ dpkg -L libssl1.0-dev | grep openssl.pc
/usr/lib/x86_64-linux-gnu/pkgconfig/openssl.pc
$ dpkg -L libssl1.0-dev:i386 | grep openssl.pc
/usr/lib/i386-linux-gnu/pkgconfig/openssl.pc
Should CMake not use CMAKE_LIBRARY_ARCHITECTURE? Is there some neat work
around? Best I can now think of is to create a script pkg-config.i386,
make that set the proper search path and tell CMake to use this script :(
Thanks --- Jan
