Build error if adding OPENSSL_NO_ENGINE macro

[garden4hu]

Hello
I got some errors when I try to add this macro OPENSSL_NO_ENGINE to CMakelist.txt. I try to add it to CMakelist.txt like this:

set( CONF "
#define OPENSSL_NO_MD2
#define OPENSSL_NO_RC5
#define OPENSSL_NO_RFC3779
#define OPENSSL_NO_EC_NISTP_64_GCC_128
#define OPENSSL_NO_ASYNC
#define OPENSSL_NO_ENGINE
${CONF}" )

I got some errors when I try to build the libs. It looks like blow:

/path/openssl-cmake-linux/crypto/engine/eng_all.c:11:
/path/openssl-cmake-linux/crypto/engine/eng_local.h:134:5: error: unknown type name 'ENGINE_CIPHERS_PTR'
    ENGINE_CIPHERS_PTR ciphers;

In fact ENGINE_CIPHERS_PTR is shielded by macro OPENSSL_NO_ENGINE in include/openssl/engine.h.
According to my experience, if this macro is defined, the engine-related source files will not participate in the compilation.
The same issue also occurs when using another macro OPENSSL_NO_COMP.

So I want to confirm whether it currently supports the use of macros to customize some functions?

Thanks very much.

Hi, unfortunately the conf is static. The reason is the official build generates some sources and headers with perl instead use of preprocessing.
