More notes on this in NOTES.WIN): + + --api=x.y.z + Don't build with support for deprecated APIs below the + specified version number.

It's likely to have to end with dash, e.g. + a-b-c- would invoke GNU compiler as a-b-c-gcc, etc. + Unfortunately cross-compiling is too case-specific to + put together one-size-fits-all instructions. You might + have to pass more flags or set up environment variables + to actually make it work. Android and iOS cases are + discussed in corresponding Configurations/10-main.cf + sections. But there are cases when this option alone is + sufficient. For example to build the mingw64 target on + Linux "--cross-compile-prefix=x86_64-w64-mingw32-" + works. Naturally provided that mingw packages are + installed. Today Debian and Ubuntu users have option to + install a number of prepackaged cross-compilers along + with corresponding run-time and development packages for + "alien" hardware. To give another example + "--cross-compile-prefix=mipsel-linux-gnu-" suffices + in such case. Needless to mention that you have to + invoke ./Configure, not ./config, and pass your target + name explicitly. + + --debug + Build OpenSSL with debugging symbols. + + --libdir=DIR + The name of the directory under the top of the installation + directory tree (see the --prefix option) where libraries will + be installed. By default this is "lib".

It only works + when using gcc or clang as the compiler. If you are + developing a patch for OpenSSL then it is recommended that + you use this option where possible. + + --with-zlib-include=DIR + The directory for the location of the zlib include file. This + option is only necessary if enable-zlib (see below) is used + and the include file is not already on the system include + path. + + --with-zlib-lib=LIB + On Unix: this is the directory containing the zlib library. + If not provided the system library path will be used. + On Windows: this is the filename of the zlib library (with or + without a path).

This flag is optional and if not provided + then "GNV$LIBZSHR", "GNV$LIBZSHR32" or "GNV$LIBZSHR64" is + used by default depending on the pointer size chosen. + + no-afalgeng + Don't build the AFALG engine. This option will be forced if + on a platform that does not support AFALG. + + enable-asan + Build with the Address sanitiser. This is a developer option + only. It may not work on all platforms and should never be + used in production environments.

On some platforms a small amount + of assembler code may still be used. + + no-async + Do not build support for async operations. + + no-autoalginit + Don't automatically load all supported ciphers and digests. + Typically OpenSSL will make available all of its supported + ciphers and digests. For a statically linked application this + may be undesirable if small executable size is an objective. + This only affects libcrypto. Ciphers and digests will have to + be loaded manually using EVP_add_cipher() and + EVP_add_digest() if this option is used. This option will + force a non-shared build. + + no-autoerrinit + Don't automatically load all libcrypto/libssl error strings. + Typically OpenSSL will automatically load human readable + error strings. For a statically linked application this may + be undesirable if small executable size is an objective. + + + no-capieng + Don't build the CAPI engine. This option will be forced if + on a platform that does not support CAPI. + + no-cms + Don't build support for CMS features + + no-comp + Don't build support for SSL/TLS compression. If this option + is left enabled (the default), then compression will only + work if the zlib or zlib-dynamic options are also chosen. + + enable-crypto-mdebug + Build support for debugging memory allocated via + OPENSSL_malloc() or OPENSSL_zalloc(). + + enable-crypto-mdebug-backtrace + As for crypto-mdebug, but additionally provide backtrace + information for allocated memory. + TO BE USED WITH CARE: this uses GNU C functionality, and + is therefore not usable for non-GNU config targets. If + your build complains about the use of '-rdynamic' or the + lack of header file execinfo.h, this option is not for you. + ALSO NOTE that even though execinfo.h is available on your + system (through Gnulib), the functions might just be stubs + that do nothing. + + no-ct + Don't build support for Certificate Transparency. + + no-deprecated + Don't build with support for any deprecated APIs.

They may not work on all + platforms and should never be used in production environments. + See the file fuzz/README.md for further details. + + no-fuzz-test + Don't runt the fuzz test suite when testing. Use with + caution, as those tests may be important. However, that + suite is particularly slow, and is therefore skippable. + + no-gost + Don't build support for GOST based ciphersuites. Note that + if this feature is enabled then GOST ciphersuites are only + available if the GOST algorithms are also available through + loading an externally supplied engine. + + enable-heartbeats + Build support for DTLS heartbeats. + + no-hw-padlock + Don't build the padlock engine. + + no-makedepend + Don't generate dependencies. + + no-multiblock + Don't build support for writing multiple records in one + go in libssl (Note: this is a different capability to the + pipelining functionality). + + no-nextprotoneg + Don't build support for the NPN TLS extension. + + no-ocsp + Don't build support for OCSP. + + no-pic + Don't build with support for Position Independent Code. + + no-posix-io + Don't use POSIX IO capabilities. + + no-psk + Don't build support for Pre-Shared Key based ciphersuites. + + no-rdrand + Don't use hardware RDRAND capabilities. + + no-rfc3779 + Don't build support for RFC3779 ("X.509 Extensions for IP + Addresses and AS Identifiers") + + sctp + Build support for SCTP + + no-shared + Do not create shared libraries, only static ones.

Normally SSE2 extension is + detected at run-time, but the decision whether or not the + machine code will be executed is taken solely on CPU + capability vector. This means that if you happen to run OS + kernel which does not support SSE2 extension on Intel P4 + processor, then your application might be exposed to + "illegal instruction" exception. There might be a way + to enable support in kernel, e.g. FreeBSD kernel can be + compiled with CPU_ENABLE_SSE, and there is a way to + disengage SSE2 code paths upon application start-up, + but if you aim for wider "audience" running such kernel, + consider no-sse2. Both the 386 and no-asm options imply + no-sse2. + + enable-ssl-trace + Build with the SSL Trace capabilities (adds the "-trace" + option to s_client and s_server). + + no-static-engine + Don't build the statically linked engines. This only + has an impact when not built "shared". + + no-stdio + Don't use any C "stdio" features. Only libcrypto and libssl + can be built in this way. Using this option will suppress + building the command line applications. Additionally since + the OpenSSL tests also use the command line applications the + tests will also be skipped. + + no-threads + Don't try to build with support for multi-threaded + applications. + + threads + Build with support for multi-threaded applications.
