This is the build.info file in 'crypto', and it tells us a little more
about what's needed to produce 'libcrypto'. LIBS is used again to
source files, 'crypto/aes.c', 'crypto/evp.c' and 'crypto/cversion.c'.
It also shows us that building the object file inferred from
'crypto/cversion.c' depends on 'crypto/buildinf.h'. Finally, it
-also shows the possibility to include raw build-file statements in a
-build.info file, in this case showing how 'buildinf.h' is built on
-Unix-like operating systems.
+also shows the possibility to declare how some files are generated
+using some script, in this case a perl script.
Two things are worth an extra note:

A few notes worth mentioning:
files, such as libraries, programs or engines. The values of SOURCE
variables must only be source files (possibly generated)
-DEPEND shows a relationship between different end product files, such
+DEPEND shows a relationship between different produced files, such
as a program depending on a library, or between an object file and
some extra source file.
engines => a list of engines. These are directly inferred from
the ENGINES variable in build.info files.
+ generate => a hash table containing 'file' => [ 'generator' ... ]
+ pairs. These are directly inferred from the GENERATE
+ variables in build.info files.
+
includes => a hash table containing 'file' => [ 'include' ... ]
pairs. These are directly inferred from the INCLUDE
variables in build.info files.
SOURCE variables, and AS source files for programs and
libraries.
+ shared_sources =>
+ a hash table just like 'sources', but only as source
+ files (object files) for building shared libraries.

As an example, here is how the build.info files example from the
section above would be digested into a %unified_info table:
[
"libssl",
],
+ "crypto/buildinf.h" =>
+ [
+ "Makefile",
+ ],
"crypto/cversion.o" =>
[
"crypto/buildinf.h",
],
- "engines/libossltest" =>
+ "engines/ossltest" =>
[
"libcrypto",
],
},
"engines" =>
[
- "engines/libossltest",
+ "engines/ossltest",
],
+ "generate" =>
+ {
+ "crypto/buildinf.h" =>
+ [
+ "util/mkbuildinf.pl",
+ "\"\$(CC)",
+ "\$(CFLAGS)\"",
+ "\"$(PLATFORM)\"",
+ ],
+ },
"includes" =>
{
"apps/openssl" =>
".",
"include",
],
- "engines/libossltest" =>
+ "engines/ossltest" =>
[
"include"
],
],
"rawlines" =>
[
- "crypto/buildinf.h : Makefile",

from static libraries, to programs from object files and libraries,
etc.
+ generatesrc - function that produces build file lines to generate
+ a source file from some input.
+
+ It's called like this:
+
+ generatesrc(src => "PATH/TO/tobegenerated",
+ generator => [ "generatingfile", ... ]
+ incs => [ "INCL/PATH", ... ],
+ deps => [ "dep1", ... ],
+ intent => one of "libs", "dso", "bin" );
+
+ 'src' has the name of the file to be generated.
+ 'generator' is the command or part of command to
+ generate the file, of which the first item is
+ expected to be the file to generate from.
+ generatesrc() is expected to analyse and figure out
+ exactly how to apply that file and how to capture
+ the result. 'incs' and 'deps' are include
+ directories and files that are used if $(CC) used as
+ an intermediary step when generating the end product
+ (the file indicated by 'src'). 'intent' indicates
+ what the generated file is going to be used for.
+
src2obj - function that produces build file lines to build an
object file from source files and associated data.
# Note 2: libobj2shlib gets both the name of the static library
# and the names of all the object files that go into it. It's up
# to the implementation to decide which to use as input.

+ # files, as the platform at hand may have a different one.
libobj2shlib(shlib => "libssl",
lib => "libssl",
- objs => [ "ssl/tls.o" ],
+ objs => [ "ssl/tls" ],
deps => [ "libcrypto" ]
ordinals => [ "ssl", "util/libssl.num" ]);
obj2lib(lib => "libssl"
- objs => [ "ssl/tls.o" ]);
+ objs => [ "ssl/tls" ]);

The returned strings from all those calls are then concatenated
together and written to the resulting build-file.
