This script is used to ensure that all OpenSSL build variants compile
|
|
properly. It can be used after modifying external/openssl/openssl.config
|
|
and re-running import_openssl.sh to check that any changes didn't break
|
|
the build.
|
|
|
|
A <build-type> is a description of a given build of the library and its
|
|
program. Its format is:
|
|
|
|
<compiler>-<system>-<arch>
|
|
|
|
Where: <compiler> is either 'gcc' or 'clang'.
|
|
<system> is 'android', 'linux' or 'darwin'.
|
|
<arch> is 'arm', 'x86' or 'mips'.
|
|
|
|
By default, it rebuilds the sources for the following build types:
|
|
"

"However, you can pass custom values on the command-line instead.

|
|
This scripts generates a custom Makefile in a temporary directory, then
|
|
launches 'make' in it to build all binaries in parallel. In case of
|
|
problem, you can use the --build-dir=<path> option to specify a custom
|
|
build-directory, which will _not_ be removed when the script exits.
|
|

For example, to better see why a build fails:
|

|
./$PROGNAME --build-dir=/tmp/mydir

make -C /tmp/mydir V=1

Valid options:

--help|-h|-? Print this message.

--build-dir=<path> Specify build directory.
|
|
--jobs=<count> Run <count> parallel build jobs [$NUM_JOBS].
|
|
-j<count> Same as --jobs=<count>.
|
|
--verbose Increase verbosity.

--quiet Decrease verbosity.
