Problem linking with libicu when building on Arch about monero HOT 23 CLOSED

Turns out it was a problem with the original (non statically compiled) boost not being entirely removed. Removed all of the leftover boost files and recompiled boost and monero project is successfully compiling now. Thank you to @0xFFFC0000 for walking me through it step by step and resolving the issue.

I think error messages tell me this is an issue with your setup. Well before hitting any error related to icu you have this error:

Hey, thanks for getting back so quick. You are right, so I looked into it and protobuf indeed does not support C++ versions less than 14. But I have C++17 so that was weird, so I looked at the cmake log and the c++ binary is being called with:
/usr/bin/c++ -I/home/thomas/monero/build/Linux/release-v0.18/release -DZMQ_STATIC -pthread -std=gnu++11 -o CMakeFiles/cm... so std=gnu++11 is being passed, which of course results in C++11 being used. I'm probably misunderstanding something but I wonder what the reason for this is and why no one else has this issue. Since gnu++11 being passed directly changes __cplusplus to be less than C++14 which is what protobuf checks for on the line where the error occurs, line 79 of policy_checks.h.

from monero.

The protobuf error message isn't an issue unless you need Trezor hardware wallet support. It should just skip it, as it says in the CMake log

-- Trezor support disabled

Regarding your boost issue, did you custom compile static boost? If yes, did you try to add the --without-icu flag, similar to how we do it in release builds?

from monero.

I did not custom build static boost, should I try doing that?

from monero.

For some reason you don't link to icu :

/usr/bin/ld: (.text+0x8df): undefined reference to `icu_74::UnicodeString::UnicodeString(char const*)'

Can you put the command you are using for cloning, installing dependencies, running the cmake and building here.

from monero.

I don't know if it's possible to compile static monero with boost installed from the package manager.

I'd recommend to custom compile static boost with the --without-icu flag since we don't need libicu for boost.

from monero.

Ah I understand, I compiled static boost with --without-icu succesfully. It works with other boost projects but gets a bunch of errors on monero probably indicating I did not compile it right. Is there any documentation on how to compile static boost in a way that would work with the monero project. Thank you.

from monero.

Can you share the errors?

I built boost with:

./bootstrap.sh --without-icu
./b2 clean
./b2 headers
./b2 -j7 --disable-icu --ignore-site-config variant=release threading=multi install link=static

from monero.

Can you try to build boost 1.64 for testing purposes instead of 1.85? 1.85 is still in development.

from monero.

Get the same errors. Got it from https://www.boost.org/users/history/version_1_64_0.html

from monero.

Just to confirm, did you do a clean build?

from monero.

Yes, both when I compiled the latest and the 1.64 boost.

from monero.

I started an arch VM to debug this issue to make sure we are not missing any issues. I was able to compile it without any issues.

I used boost 1.64.0 from https://www.boost.org/users/history/version_1_64_0.html as you mentioned.

Installed boost with exactly your commands

./bootstrap.sh --without-icu -without-libraries=python
./b2 clean
./b2 headers
sudo ./b2 -j7 --disable-icu --ignore-site-config variant=release threading=multi install link=static --disable-python

Here is the result of make release-static -j24 :

P.S. Don't worry about the dev_0xfffc_add_issue-template, that is just my personal fork of the master branch. Which doesn't have any code changes in comparison to master.

from monero.

Huh that is odd, I tried it with your commands as well (with -without-libraries=python etc) and I still get the exact same errors. The only difference is that I have to run all the commands with sudo as it doesn't have the permissions to write to the log files otherwise. Besides that I have no idea what could be causing this, maybe some environment variable I set? I also get a bunch of warnings when running the last b2 command, idk if that's normal.

from monero.

I just sudo chmod 777 -R * and built bootstrap without sudo except for the last command. I still get the exact same error when compiling monero project. In what file does net_peerlist.cpp get compiled, so I can play around with it to try and fix the ‘boost::filesystem::copy_option’ has not been declared error.

from monero.

Try https://git.townforge.net/townforge/townforge/commit/05aed8c1e74e6503ac5127ede9def28c3d0ee8d7

There is no such file as "boost_serialization_helper.h" in the latest version of monero as far as I could find. I tried it in another version (in monero-java since compiling that is my end goal) and then I get the error:

[ 86%] Linking CXX executable ../../bin/monero-gen-ssl-cert

And replacing all the listed occurences of if_exists with existing in the given files except for boost_serialization_helper.h in the latest monero src (not in monero-java) I get the following output:

Do you have a Matrix account (or IRC)? I will try to diagnose and fix this issue in live chat [1]. PM me at matrix: 0xfffc

Even when I try building in a kali vm I get errors such as this one: https://bbs.archlinux.org/viewtopic.php?id=285729. Which I fixed with adding #include <cstdint> but then I just got libunbound linking errors. I really don't know why I just can't seem to compile it anywhere I try.
