icu-config deprecated

[Greg57070]

Hello guy,

ltfs can't build on Debian 10 as icu-config has been removed from icu-devtools.

As found on this debian bugreport https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=920900, and on icu-project howto use, icu-config is now deprecated.

It's now recommanded to use pkg-config to get cflags

Thanks for the good job, keep up with it !

BR,
Grégory

Thank you for your report.

I confirmed the problem and I made a fix to handle ICU_UC package in configure.ac. It works fine but I have another problem on pkgdata program provided by ICU.

It looks the pkgdata uses icu-config internally. I believe Debian shall provide icu-config correctly.

$ pkgdata -p bin_mkltfs -m static packagelist.txt
sh: 1: icu-config: not found
sh: 1: icu-config: not found
pkgdata: icu-config: No icu-config found. (fix PATH or use -O option)
 required parameter is missing: -O is required for static and shared builds.
Run 'pkgdata --help' for help.

Thanks

Hi @Greg57070,

I realized a comment is added to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=920900, I believe you commented.

Thank you very much.

Just to let you know, I have the same problem. LTFS runs well on debian 8 and 9 but on debian 10 I'm getting probably the same errors due to icu no longer being supported.

I attached the Dockerfile I use to build a docker image (I run LTFS in a container but that should not matter I guess).

The build process works if I change the line
FROM debian:buster
in the attached Dockerfile to
FROM debian:stretch
ro
FROM debian:jessie

Dockerfile.txt

Hereby also attached the output of the full build process that fails in Debian Buster:

Has anybody figured out a way to compile this in Ubuntu 19 ?

[piste-jp]

I found a way to make it compilable. At this time, this is a quick patch but I can build LTFS on Ubuntu19.

The pkgdata command calls icu-config --incpkgdatafile and get a path of pkgdata.inc. So it is good to create a dummy script to return the path of pkgdata.inc file.

On Ubuntu19,

1. Create /usr/bin/icu-config
2. Write a code to return a path of pkgdata.inc in /usr/bin/icu-config
3. Set executable bit of /usr/bin/icu-config

The sample script for Ubuntu19 is

#!/bin/sh

echo '/usr/lib/x86_64-linux-gnu/icu/pkgdata.inc'

May be you need to adjust the path on your machine.

is this related to this issue ?

[piste-jp]

No, I don't think it is related directly. But I might miss something to write in the previous comment...

My build step is little bit tricky at this time. I will try to enhance this later if no one post a PR about this.

Step1 : Edit configure.ac

diff --git a/configure.ac b/configure.ac
index 95c3958..6f56907 100644
--- a/configure.ac
+++ b/configure.ac
@@ -342,7 +342,7 @@ ICU_MODULE_CFLAGS="`icu-config --cppflags 2> /dev/null`";
 ICU_MODULE_LIBS="`icu-config --ldflags 2> /dev/null`";
 if test -z "$ICU_MODULE_LIBS"
 then
-    PKG_CHECK_MODULES([ICU_MODULE], [icu >= 0.21])
+    PKG_CHECK_MODULES([ICU_MODULE], [icu-uc >= 0.21])
 fi

 AC_MSG_CHECKING([use latest ICU])

Step2 : Run configuration

$ ./autogen.sh
$ ./configure

Step3 : Create icu-config

1. Create /usr/bin/icu-config
2. Write a code to return a path of pkgdata.inc in /usr/bin/icu-config
3. Set executable bit of /usr/bin/icu-config

The sample script for Ubuntu19 is

#!/bin/sh

echo '/usr/lib/x86_64-linux-gnu/icu/pkgdata.inc'

Step4 : make

$ ./make

[piste-jp]

I wrote a minimal script to support ltfs build on Debian10 and Ubuntu19.10. And also I made build environemts on GitHub Actions.

#!/bin/sh

opts=$1

case $opts in
  '--cppflags')
    echo '' ;;
  '--ldflags')
    echo '-licuuc -licudata' ;;
  *)
    echo '/usr/lib/x86_64-linux-gnu/icu/pkgdata.inc' ;;
esac

Hi. In my Ubuntu 20.04 environment I had to add -ldl to to the flags for errors related to 'dlopen'

$ cat /etc/issue
