Build problem

Submitted by Thilo on

Hi,
I'm currently switching to github branch libraw 0.21-stable and tried to compile a more recent version of libraw. Unfortunately, running make after ./configure, I'm getting below error on macos Sonoma. What is needed to fix this?
Best,
Thilo

macbook:LibRaw user$ make
CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/sh '/Users/tbauer/git/LibRaw/missing' aclocal-1.16 -I m4
/Users/tbauer/git/LibRaw/missing: line 81: aclocal-1.16: command not found
WARNING: 'aclocal-1.16' is missing on your system.
You should only need it if you modified 'acinclude.m4' or
'configure.ac' or m4 files included by 'configure.ac'.
The 'aclocal' program is part of the GNU Automake package:

It also requires GNU Autoconf, GNU m4 and Perl in order to run:

make: *** [aclocal.m4] Error 127

You need to either install

You need to either install autotools or just use make -f Makefile.dist
(adjust makefile to meet your needs: JPEG comression support, etc)

Hi Alex,

Hi Alex,

Again, thanks for your quick support. I realized, that I had to update the whole brew installation on my mac and also install and upgrade a lot more tools and libraries, like automake or pkg-config, which is mentioned in an earlier post.

Also I had to install libraries, like jasper, or zlib. From a perspective of such an upgraded full fledged development machine, it is hard to judge, what libraries need to be provided with libraw bundled with an app on a plain macos end-user installation.

All dependencies (additional libraries) that are now compiled with libraw obviously do not exist on a barebone macos installation, esp. without additional development tools like XCode and additional add-ons installed using homebrew installation manager.

Is there a list of libraries (DLLs, share libs) that need to be provided together with any application that relies on libraw and not running in a full fledged development machine environment?

It would be a nightmare for a developer of collecting complaints from end-users that quickly refuse to use your app because its not running on a real world mac. :-)

Thanks,

Thilo

With default/unchanged

With default/unchanged Makefile.dist LibRaw requires zlib only (present in base macOS).

All additional dependencies (libjpeg, RawSpeed, Adobe DNG SDK) are optional and disabled by default.

Thanks again. I could solve

Thanks again. I could solve the compile problems. Now, I'm getting a lot of undefined symbols when trying to link the library against my app. Most of them sound like the optional packages have been compiled into the library, now missing their references when linking against the static library for branch "LibRaw 0.21-stable", which sounds weird.

ld: Undefined symbols:
  LibRaw::open_file(char const*), referenced from:
      _Java_net_bwmc_libraw_LibRawImageLoader_loadRawImage in LibRawImageLoader.o

I tried to resolve this, by rolling back to version 0.20 and rebuild the library for this version, which previously worked. However, the list of undefined references I get while linking is even longer. Now, it sounds like optional libraries haven't been detected as optional when switching to branch "LibRaw 0.20-stable" and rebuilding after 'make clean'.

ld: Undefined symbols:
  LibRaw::open_file(char const*), referenced from:
      _Java_net_bwmc_libraw_LibRawImageLoader_loadRawImage in LibRawImageLoader.o
  _jpeg_CreateDecompress, referenced from:

      LibRaw::kodak_jpeg_load_raw() in libraw.a[13](kodak_decoders.o)
  _jpeg_abort_decompress, referenced from:

  _jpeg_destroy_decompress, referenced from:

  _jpeg_finish_decompress, referenced from:

      LibRaw::kodak_jpeg_load_raw() in libraw.a[13](kodak_decoders.o)
  ...

I followed the instructions how to compile by executing these commands:

autoreconf --install
./configure
make

Also I tried 'make clean' and rebuild from scratch and removed many files manually, with no success.

Any suggestion how to solve this?

Undefined symbols: LibRaw:

Undefined symbols: LibRaw::open_file means "You've forgot to link with libraw library"

The second group of errors means: you've build libraw with JPEG decompression support but forgot to add libjpeg to your linker input.
