If ExifTool is used, binary compiled using perlcc depends on Config.so and cwd.so, even if --static/--staticxs is used.

[jiucenglou]

If ExifTool is used, binary compiled using perlcc depends on Config.so and Cwd.so, even if --static/--staticxs is used.
The reason might be that ExifTool utilizes Config.so .
The problem is that the binary compiled requires cperl installation and is not portable any more.
That is to say, the binary cannot run on another machine without cperl at the expected position.

Output of strace is shown below

stat("/usr/local/lib/cperl/5.30.0/x86_64-linux/auto/Config/Config.so", 0x7f4f8d872ba0) = -1 ENOENT (No such file or directory)
write(2, "Error: load_file /usr/local/lib/"..., 90Error: load_file /usr/local/lib/cperl/5.30.0/x86_64-linux/auto/Config/Config.so not found
) = 90

Could you suggest how to build the "true" static binary under this circumstance ? Many thanks !

[rurban]

A true static binary needs the Perl to be compiled static, with all modules be compiled static also. It is possible, but I never heard that anyone did that.

[jiucenglou]

Is it possible to compile everything statically base on the install instruction for cperl (shown below) ? :D If yes, could you suggest which switches one should use ? Many thanks !

http://perl11.org/cperl/

INSTALL:

Simple:

    ./Configure -sder -Dusedevel -Dusecperl
    make -s -j4
    make -s -j4 test
    sudo make install

Experts:

    ./Configure -sder -Dusedevel -Dusecperl \
      -Accflags='-msse4.2 -DPERL_FAKE_SIGNATURE' --optimize='-O3 -g' \
      -Dinstallman1dir=none -Dinstallman3dir=none -Dinstallsiteman1dir=none \
      -Dinstallsiteman3dir=none
    make -s -j4 ECHO=true
    make -s -j4 ECHO=true test
    sudo make install

Also interested if one can compile cperl statically with its modules - for the goal of embedding the interpreter statically to run some scripts, similar to what might (?) be accomplished with staticperl. Maybe it even can be a lightweight alternative to WebPerl and compile fully into WebAssembly. It would also be very useful for perlcc

[vadimkantorov]

Here's how I tried configuring cperl to compile statically: bash +x ./Configure -sde -Uusedl -Dprefix=$PREFIX
log.zip

On my system it breaks with:

Run make depend now? [y]

[vadimkantorov]

@rurban I tried to compile cperl with all modules in static way: -Dstatic_ext="B B/C Compress/Raw/Bzip2 Compress/Raw/Zlib Config Cpanel/JSON/XS Cwd Data/Dumper Devel/NYTProf Devel/PPPort Devel/Peek Digest/MD5 Digest/SHA Encode Fcntl File/DosGlob File/Glob Filter/Util/Call Hash/Util Hash/Util/FieldHash I18N/Langinfo IO IPC/SysV Internals/DumpArenas List/Util MIME/Base64 Math/BigInt/FastCalc Opcode POSIX PerlIO/encoding PerlIO/mmap PerlIO/scalar PerlIO/via SDBM_File Socket Storable Sys/Hostname Sys/Syslog Term/ReadKey Tie/Hash/NamedCapture Time/HiRes Time/Piece Unicode/Collate Unicode/Normalize XS/APItest XS/Typemap YAML/Safe mro re threads threads/shared"

At the end of compilation (linking time of the final cperl executable?) I got this error:

This is not so many errors, so hopefully can be fixed easily

[vadimkantorov]

Maybe it's Unicode/Normalize module to blame. I'll try to confirm.

PL_nan warning is concerning though: it seems that two ifdef branches trigger on my system (WSLv1, Ubuntu 18.04) and it gets defined twice:

1. cperl/perl.h

   Line 7602 in 071f7ab

   INFNAN_U8_NV_DECL PL_nan = { { DOUBLENANBYTES } };

2. cperl/perl.h

   Line 7634 in 071f7ab

   INFNAN_NV_U8_DECL PL_nan;

[rurban]

The duplicate Normalize symbols are easy to fix, and should be in a seperate ticket.

The nan stuff is an upstream problem, and indeed a severe bug

[vadimkantorov]

Also, regular expression module still got put into some dynamic_ext_re

[vadimkantorov]

A more lightweight setup:

./Configure -sde -Dprefix=$PREFIX -Dstatic_ext="Encode Config IO Fcntl Cwd Storable Digest/MD5 List/Util Time/HiRes File/Glob PerlIO/scalar"
bash +x Makefile.SH
make -j4
# succeeds

# remove installman line
make install

[vadimkantorov]

What is XS and how do I link it statically?

[vadimkantorov]

Basically, static perl compiles fine (except for NaN issue), but Glob module fails:

vadimkantorov@DESKTOP-4UF8FID:/mnt/c/Users/user/wiptlmgr/cperl-5.30.0$ ./perl -Ilib -I. installperl --destdir=

[vadimkantorov]

It seems that the reason is that XSLoader module and XSLoader::load() doesn't work well.

I found XSLoader in Makefile:

DL_SRC = ext/DynaLoader/DynaLoader.xs ext/DynaLoader/dlboot.c ext/DynaLoader/dlutils.c          ext/DynaLoader/XSLoader.c

So it seems it still wants to do dynamic loading for something. What does it try to load dynamically for globbinb? libc?

[vadimkantorov]

Here lives that Glob.pm file: https://github.com/perl11/cperl/tree/0f5b639e779cc36fc203afefe79c7810906fac65/ext/File-Glob

Is XSLoader FFI supposed to support XSLoader::load() even if https://github.com/perl11/cperl/blob/0f5b639e779cc36fc203afefe79c7810906fac65/ext/File-Glob/Glob.xs is compiled statically?
