[OpenSSL-3.0LTS] automatically generate N6's Makefile from configdata.pm

[Takehiko NOZAKI]

TNF HEAD seems its Makefile is automatically generated from OpenSSL generated Makefile(and *.d file) by shell script and awk.

‌

but OpenSSL has it’s Makefile generation tools by perl and all configuration data is stored in configdata\.pm, it’s better to using it.

[Takehiko NOZAKI]

first, run Configure with BSD-generic32 target.

it generates MI part.

second, run Configure with NetBSD-${MACHINE_CPU} target(added target by me).

the difference between NetBSD-${MACHINE_CPU} and BSD-generic32 becomes MD part.

all libraries that OpenSSL is build is recored as $unified_info{'libraries'}

our %unified_info = (
...
    "libraries" => [
        "apps/libapps.a",
        "libcrypto",
        "libssl",
        "providers/libcommon.a",
        "providers/libdefault.a",
        "providers/liblegacy.a",
        "test/libtestutil.a"
    ],
...

lib*.a is archive library, if $unified_info{'attributes'}->{'libraries'}->{$library}->{'noinst'} is 1, library is private and no need to be installed.

our %unified_info = (
    "attributes" => {
...
        "libraries" => {
            "apps/libapps.a" => {
                "noinst" => "1"
            },
            "providers/libcommon.a" => {
                "noinst" => "1"
            },
            "providers/libdefault.a" => {
                "noinst" => "1"
            },
            "providers/liblegacy.a" => {
                "noinst" => "1"
            },
            "test/libtestutil.a" => {
                "has_main" => "1",
                "noinst" => "1"
            }
        },
...

lib*.a is used not only for static linking apps/testcases, also for shared libraries. so that PIC(lib*_pic.a) archive should be build.

lib* is shared library, always installed.

[Takehiko NOZAKI]

archive libraries dependency is stored as $unified_info{'sources'}->{$library}

our %unified_info = (
...
    "sources" => {
...
        "apps/libapps.a" => [
            "apps/lib/libapps-lib-app_libctx.o",
...
        ],
        "libcrypto" => [
            "crypto/aes/libcrypto-lib-aes_cbc.o",
...
            "providers/libdefault.a"
        ], 

‌

shared libraries dependency is stored as $unified_info{'shared_sources'}->{$library}

our %unified_info = (
...
    "shared_sources" => {
        "libcrypto" => [
            "crypto/aes/libcrypto-shlib-aes_cbc.o",
...
            "libcrypto.ld",
...
            "providers/libdefault.a"
        ],

*.ld is for ELF symbol versioning, see ld(1)'s --version-script option.

\*.o is object file.

lib*-shlib-*.o is PIC object, lib*-lib-*.o is static linked object.

it’s source code also recorded in $unified_info{'sources'}->{$object}.

our %unified_info = (
...
    "sources" => {
...
        "apps/lib/libapps-lib-app_libctx.o" => [
            "../../../dist/apps/lib/app_libctx.c"
        ],
...
        "crypto/aes/libcrypto-shlib-aes_cbc.o" => [
            "../../../dist/crypto/aes/aes_cbc.c"
        ],

‌

[Takehiko NOZAKI]

\$unified_info{'defines'}->{$library} is CPPFLAGS definitions.

our %unified_info = (
...
    "defines" => {
        "crypto/providers/liblegacy.a" => [
            "SHA1_ASM"
        ],
        "engines/loader_attic" => [
            "OPENSSL_NO_PROVIDER_CODE"
        ],
        "libcrypto" => [
            "GHASH_ASM",
            "OPENSSL_BN_ASM_MONT",
            "OPENSSL_CPUID_OBJ",
            "SHA1_ASM"
        ],
        "providers/libcommon.a" => [
            "OPENSSL_BN_ASM_MONT",
            "OPENSSL_CPUID_OBJ"
        ],
        "providers/libdefault.a" => [
            "OPENSSL_CPUID_OBJ",
            "SHA1_ASM"
        ],
        "providers/libfips.a" => [
            "FIPS_MODULE",
            "GHASH_ASM",
            "OPENSSL_BN_ASM_MONT",
            "OPENSSL_CPUID_OBJ",
            "SHA1_ASM"
        ],
        "providers/liblegacy.a" => [

        ],

public header files to be installed is not recored on configdata\.pm, using find(1) is only way:

install_dev: install_runtime_libs
        @[ -n "$(INSTALLTOP)" ] || (echo INSTALLTOP should not be empty; exit 1)
        @$(ECHO) "*** Installing development files"
        @$(PERL) $(SRCDIR)/util/mkdir-p.pl "$(DESTDIR)$(INSTALLTOP)/include/openssl"
        @ :
        @set -e; for i in $(SRCDIR)/include/openssl/*.h \
                          $(BLDDIR)/include/openssl/*.h; do \
                fn=`basename $$i`; \
                $(ECHO) "install $$i -> $(DESTDIR)$(INSTALLTOP)/include/openssl/$$fn"; \
                cp $$i "$(DESTDIR)$(INSTALLTOP)/include/openssl/$$fn"; \
                chmod 644 "$(DESTDIR)$(INSTALLTOP)/include/openssl/$$fn"; \
        done

also mandoc to be installed is not recored on configdata\.pm, use find(1) too:

install_man_docs: build_man_docs
        @[ -n "$(INSTALLTOP)" ] || (echo INSTALLTOP should not be empty; exit 1)
        @$(PERL) $(SRCDIR)/util/mkdir-p.pl "$(DESTDIR)$(MANDIR)/man1"
        @$(PERL) $(SRCDIR)/util/mkdir-p.pl "$(DESTDIR)$(MANDIR)/man3"
        @$(PERL) $(SRCDIR)/util/mkdir-p.pl "$(DESTDIR)$(MANDIR)/man5"
        @$(PERL) $(SRCDIR)/util/mkdir-p.pl "$(DESTDIR)$(MANDIR)/man7"
        @$(ECHO) "*** Installing manpages"
        @set -e; for x in dummy $(MANDOCS1); do \
                if [ "$$x" = "dummy" ]; then continue; fi; \
                fn=`basename $$x`; \
                $(ECHO) "install $$x -> $(DESTDIR)$(MANDIR)/man1/$${fn}$(MANSUFFIX)"; \
                cp $$x "$(DESTDIR)$(MANDIR)/man1/$${fn}$(MANSUFFIX)"; \
                chmod 644 "$(DESTDIR)$(MANDIR)/man1/$${fn}$(MANSUFFIX)"; \
                $(PERL) $(SRCDIR)/util/write-man-symlinks install $(SRCDIR)/doc/man1 $(BLDDIR)/doc/man1 $${fn}$(MANSUFFIX) "$
(DESTDIR)$(MANDIR)/man1"; \
        done
...
        @set -e; for x in dummy $(MANDOCS7); do \
                if [ "$$x" = "dummy" ]; then continue; fi; \
                fn=`basename $$x`; \
                $(ECHO) "install $$x -> $(DESTDIR)$(MANDIR)/man7/$${fn}$(MANSUFFIX)"; \
                cp $$x "$(DESTDIR)$(MANDIR)/man7/$${fn}$(MANSUFFIX)"; \
                chmod 644 "$(DESTDIR)$(MANDIR)/man7/$${fn}$(MANSUFFIX)"; \
                $(PERL) $(SRCDIR)/util/write-man-symlinks install $(SRCDIR)/doc/man7 $(BLDDIR)/doc/man7 $${fn}$(MANSUFFIX) "$
(DESTDIR)$(MANDIR)/man7"; \
        done

hmm, shlib-*.o and lib-*.o is same PIC object(same as N’s *.pico and lib*_pic.a).
