This crate contains the logic to build OpenSSL and is intended to be consumed by
the openssl-sys
crate. You likely in theory aren't interacting with this too
much!

Building OpenSSL for windows-msvc
targets, users can choose whether to enable
assembly language routines, which requires nasm.
The build process will automatically detect whether nasm.exe
is installed in
PATH. If found, the assembly language routines will be enabled (in other words,
the no-asm
option will NOT be configured).
You can manipulate this behavior by setting the OPENSSL_RUST_USE_NASM
environment
variable:
1
: Force enable the assembly language routines. (panic ifnasm.exe
is not availible.)0
: Force disable the assembly language routines even if thenasm.exe
can be found in PATH.- not set: Let the build process automatically detect whether
nasm.exe
is installed. If found, enable. If not, disable. However, this environment variable does not take effects on non-windows platforms.
