The brew ICU package contains icu-config in /usr/local/Cellar/icu4c/60.2/bin/icu-config, which is not included in the standard path.

I have linked it into a standard path with ln -s /usr/local/Cellar/icu4c/60.2/bin/icu-config /usr/local/bin/icu-config.

Now, with sudo pip3 install pyicu, it finally builds successfully!

As icu-config is obviously a required precondition for building PyICU, it should not be assumed that it is found in the path. Instead, the PyICU setup script should check for it's presence and show an appropriate error message if not found.

ovalhub commented on August 17, 2024 5

Either have your installation of ICU make the icu-config program available
or setup the env vars below according to your setup:

$ export ICU_VERSION=
$ export PYICU_INCLUDES=/include
$ export PYICU_LFLAGS=-L/lib
$ export PYICU_CFLAGS=-std=c++11

or edit setup.py and set INCLUDES, LFLAGS and CFLAGS accordingly.

In my case I just did

export ICU_VERSION=63.1
export PYICU_INCLUDES=/usr/local/Cellar/icu4c/63.1/include
export PYICU_LFLAGS=-L/usr/local/Cellar/icu4c/63.1/lib
export PYICU_CFLAGS=-std=c++11
pip install pyicu

https://gist.github.com/loretoparisi/294b8f536750a18746fc6f43f7859928

the problem is when importing the library!

Nice bits of info a bit sparse/scattered. In summary what worked for future references:
I have MacOS 10.13. My project required PyICU-1.8 and the only icu4c that worked was version 57.1
$ brew remove icu4c
$ cd /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core
$ git checkout 1e62c645b2fc2d82042d9f7c364c6a246f2e11ed Formula/icu4c.rb #this is the latest commit with 57.1
$ brew install icu4c
$ ln -s /usr/local/Cellar/icu4c/57.1/bin/icu-config /usr/local/bin/icu-config
My .bash_profile

 22 export ICU_VERSION=57.1
 23 export PYICU_INCLUDES=/usr/local/Cellar/icu4c/${ICU_VERSION}/include
 24 export PYICU_LFLAGS=-L/usr/local/Cellar/icu4c/${ICU_VERSION}/lib
 25 export PYICU_CFLAGS=-std=c++11:-DPYICU_VER='"1.8"'

$ source ~/.bash_profile && pip install PyICU==1.8 --ignore-installed

from pyicu.

akhudek commented on August 17, 2024 3

It turns out that the right env var is:

export PYICU_CFLAGS=-std=c++11:-DPYICU_VER='"2.0.3"'

The : causes the arguments to be treated separately and the single quotes cause the double quotes to be included in the define.

from pyicu.

yu-imu commented on August 17, 2024 2

I also experienced this problem.

[Errno 2] No such file or directory: 'icu-config': 'icu-config'

I fixed as follow and finally installed pyicu
I already installed icu4c as follow
$ brew install icu4c
$ brew link icu4c
So, make to a path to .bash_profile
echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.bash_profile
echo 'export PATH="/usr/local/opt/icu4c/sbin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile
pip3 install pyicu

from pyicu.

ovalhub commented on August 17, 2024 1

Don’t use a space character after -D: CFLAGS=-DPYICU_VER=2.0.2 You shouldn’t have to set this, by the way... But if you must, use PYICU_CFLAGS instead.

I'm having the same series of issues that @workflowsguy had.

If I install with CFLAGS=-I/usr/local/opt/icu4c/include LDFLAGS=-L/usr/local/opt/icu4c/lib pip install pyicu, it installed successfully (this is all over the internet but mainly for ICU versions < 60 as far as I can tell). However, running my script that depends on pyicu (via polyglot) after that gives

Which according to this stackoverflow question implies something was compiled incorrectly, so I tried the solutions offered above. And I'm at the same error: invalid suffix '.3' on floating constant error.

This did the trick for me. No environment variables at all!

nmooman commented on August 17, 2024 1

On Mac:
%brew install intltool icu4c gettext
%brew link icu4c gettext --force
%ls -arlt /usr/local/opt/icu4c/bin/icu-config
%git clone https://github.com/ovalhub/pyicu.git
%cd pyicu
check your icu4c version by
%ls /usr/local/Cellar/icu4c/
i.e., 59.1_1 61.1 62.1
%sudo ICU_VERSION='62.1' python3.6 setup.py build
%sudo ICU_VERSION='62.1' python3.6 setup.py install
%sudo pip3.6 install polyglot --upgrade

You might need if you encountered issues:
%export PYICU_INCLUDES=/include
%export PYICU_LFLAGS=-L/lib
%export PYICU_CFLAGS=-std=c++11

and in your setup.py
try:
ICU_VERSION = os.environ['ICU_VERSION']
#ICU_VERSION = '62.1'
except:
try:
#ICU_VERSION = check_output(('icu-config', '--version')).strip()
ICU_VERSION = '62.1'
if sys.version_info >= (3,):
ICU_VERSION = str(ICU_VERSION, 'ascii')
except:

I do not understand what you mean by

But if you must, use PYICU_CFLAGS instead.

If I enter export PYICU_CFLAGS="-std=c++11 -DPYICU_VER=2.0.2" and then pip3 install pyicu, I get an error error: invalid value 'c++11 -DPYICU_VER=2.0.2' in '-std=c++11 -DPYICU_VER=2.0.2

from pyicu.

ovalhub commented on August 17, 2024

Use CFLAGS='-DPYICU_VER="2.0.2"' But really, you shouldn't have to set this. You should be getting this set automatically from the CFLAGS dict at line 78 in setup.py. I'd be very curious as to why setting this var is necessary. Andi..

Regardless of whether I enter
CFLAGS='-DPYICU_VER="2.0.2"' pip3 install pyicu or just pip3 install pyicu,

PYICU simply does not build, giving different error messages based on the command entered, as mentioned above.

The environment variables are set as per your answers:

ICU_VERSION=60.2
PYICU_CFLAGS=-std=c++11
PYICU_INCLUDES=/usr/local/opt/icu4c/include
PYICU_LFLAGS=-L/usr/local/opt/icu4c/lib

I don't think you do, you were able to do a build whereas @WorkflowGuy, for some strange reason, doesn't have PYICU_VER set - you do, otherwise your build would have failed.

If I install with `CFLAGS=-I/usr/local/opt/icu4c/include LDFLAGS=-L/usr/local/opt/icu4c/lib pip install pyicu`, it installed successfully (this is all over the internet but mainly for ICU versions < 60 as far as I can tell). However, running my script that depends on pyicu (via polyglot) after that gives

Why are you doing this instead of having icu-config do this for you ? If you don't have icu-config installed, then install it. On linux, it seems to come with the icu-dev package. If you build ICU from sources on Mac, it's installed with it. If you use homebrew or something else, there may be another package you need to install, ask them. Whichever way you installed ICU, there is an icu-config program that comes with it on unix (linux, mac, etc..) that remembers where and how it was configured. PyICU uses icu-config to set all the necessary c++ compiler and linker flags accordingly. If you don't have / can't install icu-config, then you need to ensure that the ICU header files and the ICU libs you compile and link against are the same as the ICU shared libs you are going to run with.

The missing __ZNK6icu_6014Transliterator12getTargetSetERNS_10UnicodeSetE is a symptom of a mismatch between the ICU version you built PyICU with and the one you then running with. You probably have multiple versions of ICU installed. Check that you don't have DYLD_LIBRARY_PATH set to an old ICU version or that you are compiling and linking against the correct version of ICU. You can use the 'otool' utility to find which actuall shared ICU library your _icu.so python extension is going to try to load: For me, this looks like: $ otool -L _icu.so libicui18n.60.dylib (compatibility version 60.0.0, current version 60.2.0) libicuuc.60.dylib (compatibility version 60.0.0, current version 60.2.0) ../lib/libicudata.60.2.dylib (compatibility version 60.0.0, current version 60.2.0) /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 104.1.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1238.50.2) /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 489.0.0) For you, it better reflect where you built and installed ICU to.

Which according to [this stackoverflow question](https://stackoverflow.com/questions/29777337/macosx-boost-python-pyftgl-symbol-not-found-expected-in-flat-namespace) implies something was compiled incorrectly, so I tried the solutions offered above. And I'm at the same `error: invalid suffix '.3' on floating constant` error.

No, this is irrelevant. You do not need to set PYICU_VER manually, this is done for you in PyICU's setup.py. If you _must_ continue setting it, you must ensure it's enclosed in "". PYICU_CFLAGS='-std=c++11 -DPYICU_VER="2.0.3"' but this is not the issue you're facing. Andi..

On Thu, 1 Feb 2018, workflowsguy wrote: The `brew` ICU package contains `icu-config` in `/usr/local/Cellar/icu4c/60.2/bin/icu-config`, which is not included in the standard path. I have linked it into a standard path with `ln -s /usr/local/Cellar/icu4c/60.2/bin/icu-config /usr/local/bin/icu-config`. Now, with `sudo pip3 install pyicu`, it finally builds successfully! As `icu-config` is obviously a required precondition for building `PyICU`, it should not be assumed that it is found in the path. Instead, the PyICU setup script should check for it's presence and show an appropriate error message if not found.

The configure_with_icu_config function starting at line 28 in setup.py does this. It prints an error message and re-raises the exception raised by the check_output() function above it. In other words, if you don't have icu-config or it can be found or it fails to run, you're back to doing what is asked of you line 26 in README.md, that is, manually setting the the ``INCLUDES``, ``LFLAGS``, ``CFLAGS`` and ``LIBRARIES`` dictionaries in ``setup.py`` with the values for your platform. Andi..

Don’t use a space character after -D: CFLAGS=-DPYICU_VER=2.0.2 You shouldn’t have to set this, by the way... But if you must, use PYICU_CFLAGS instead.

Thanks! This worked for me!

Hultner commented on August 17, 2024

@will3216 I'm not able to get it to work with your solution, the only way for me to install it is to set up the path or link icu-config manually.

I can get it to install successfully on my machine with some hassle but it's hard for me to be able to create a reproducible setup.py so that other developers in my team are able to install the package without to much hassle.

Brew won't let me force link icu4c and gives the following output if I try.

$ brew link icu4c                                                                                                                                                                                                                                                                              
Warning: Refusing to link macOS-provided software: icu4c
If you need to have icu4c first in your PATH run:
  echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.zshrc
  echo 'export PATH="/usr/local/opt/icu4c/sbin:$PATH"' >> ~/.zshrc

For compilers to find icu4c you may need to set:
  export LDFLAGS="-L/usr/local/opt/icu4c/lib"
  export CPPFLAGS="-I/usr/local/opt/icu4c/include"

For pkg-config to find icu4c you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/icu4c/lib/pkgconfig"

will3216 commented on August 17, 2024

@Hultner did you install icu4c with brew? It seems like that warning is indicating it was installed directly on your OS. This has become a requirement for each person on our team that needs to load our ecosystem and the solution provided above worked for each of us thus far. That said, your setup could easily be different in some way. What version of macOS are running?

from pyicu.

Hultner commented on August 17, 2024

@will3216 Yep, I installed it through brew. I've never knowingly installed it directly through my OS. It might have been installed previously by some other software, may it be bundled with xcode or similar?

from pyicu.

will3216 commented on August 17, 2024

@Hultner I'm not sure then. What I do know is that the command you listed above was brew link icu4c not brew link icu4c --force. If that doesn't work, I'd recommend going with @DiegoCoder's solution (being sure to change the ICU_VERSION to whatever version you have installed).

from pyicu.

Hultner commented on August 17, 2024

@will3216 I tried both with the same result. I did get it to work when setting up the path manually and defining ICU_VERSION in my environment before running pipenv install on the project. It's just a bit more cumbersome for our developers this way since we need to set up new PATH variables etc.

from pyicu.

will3216 commented on August 17, 2024

@Hultner Yeah, that approach is definitely a bit cumbersome and easy to forget down the line when you onboard new team members, but I suspect that the issue you are running into might be specific to your particular environment. It may be possible for other members of your team to use the brew link force approach (unless of course the issue is derived from a tool your whole team uses)

@loretoparisi Were you able to resolve this problem? I just ran into it.

piyiotisk commented on August 17, 2024

In my case I just did

export ICU_VERSION=63.1
export PYICU_INCLUDES=/usr/local/Cellar/icu4c/63.1/include
export PYICU_LFLAGS=-L/usr/local/Cellar/icu4c/63.1/lib

pip install pyicu

https://gist.github.com/loretoparisi/294b8f536750a18746fc6f43f7859928

the problem is when importing the library!

ip-192-168-22-157:~ loretoparisi$ python -c "import icu"

Yes, I was able to resolve this. Basically, reading this guide https://docs.brew.sh/Homebrew-and-Python you will need to run CFLAGS=-I$(brew --prefix)/include LDFLAGS=-L$(brew --prefix)/lib pip install pyicu` without using a virtualenv. This will pass the correct compiler parameters so the brew icu4c could communicate with the python lib. After that enable the virtualenv and you will be good to go
