[openssl-dev] mingw: pkg-config --libs outputs gdi32 before crypto

[Richard Levitte]

This is quite odd.  Just for comparison, I tried the same on my laptop
(running Debian):

    : ; pkg-config --static --libs-only-l openssl
    -lssl -ldl -lcrypto -ldl 

My .pc files look like this:

    : ; cat /usr/lib/x86_64-linux-gnu/pkgconfig/openssl.pc
    prefix=/usr
    exec_prefix=${prefix}
    libdir=${exec_prefix}/lib/x86_64-linux-gnu
    includedir=${prefix}/include
    
    Name: OpenSSL
    Description: Secure Sockets Layer and cryptography libraries and tools
    Version: 1.0.2d
    Requires: libssl libcrypto
    : ; cat /usr/lib/x86_64-linux-gnu/pkgconfig/libssl.pc 
    prefix=/usr
    exec_prefix=${prefix}
    libdir=${exec_prefix}/lib/x86_64-linux-gnu
    includedir=${prefix}/include
    
    Name: OpenSSL-libssl

    Libs.private: -ldl
    Cflags: -I${includedir} 
    : ; cat /usr/lib/x86_64-linux-gnu/pkgconfig/libcrypto.pc 
    prefix=/usr
    exec_prefix=${prefix}
    libdir=${exec_prefix}/lib/x86_64-linux-gnu
    includedir=${prefix}/include

As you can see, my '-ldl' is specified the same way as your '-lws2_32
-lgdi32 -lcrypt32' (*).

    : ; pkg-config --version
    0.28

Cheers,
Richard

(*) quite interestingly, really, as libssl doesn't have any direct
dependency with libdl...
