Please use v2 branch while I merge it with master/main.

Hi I have the same problem, with Ubuntu 18, 64 Bit, golang 1.13
Also for the other td libraraies like (ltdjson_static, _private, ...), I saw some libraries has only .a file and .so files are not built

Would you please explain how to "use v2 branch while merge it with master/main"?
Thanks in advance.

thanks.

@dfelici87
As far as I understood to use the new version of https://github.com/Arman92/go-tdlib which is based on lc++ (not lstdc++)
you need to build tdlib based on lc++ as:

tdlib/td#780

apt-get install make git zlib1g-dev libssl-dev gperf php cmake clang-6.0 libc++abi-dev libc++-dev
git clone https://github.com/tdlib/td.git
cd td
rm -rf build
mkdir build
cd build
export CXXFLAGS="-stdlib=libc++"
CC=/usr/bin/clang-6.0 CXX=/usr/bin/clang++-6.0 cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX:PATH=../tdlib -DCMAKE_AR=/usr/bin/llvm-ar-6.0 -DCMAKE_NM=/usr/bin/llvm-nm-6.0 -DCMAKE_OBJDUMP=/usr/bin/llvm-objdump-6.0 -DCMAKE_RANLIB=/usr/bin/llvm-ranlib-6.0 ..
cmake --build . --target install
cd ..
cd ..
ls -l td/tdlib

this may resolve the -lc++ issue.

Same problem, but i'm from alpine, i can't install libc++abi-dev

[Laky-64]

*Edit:
Same problem also on Arm64v8 & Arm32v7 (Buster)

My Docker Machine:
https://github.com/DockerTDLib/TDLib/blob/main/linux/Dockerfile

Docker machine from Docker Hub
https://hub.docker.com/repository/docker/laky64/tdlib

My Docker Building Machine:

FROM laky64/tdlib:linux-arm64 AS golang
RUN apt install libc++-dev libc++abi-dev -y
RUN git clone https://github.com/OwlGramDev/TelegramDCStatus
RUN cd TelegramDCStatus && go build -o /usr/src/outputs/TgStatus .

# cd /root/go/pkg/mod/github.com/\!arman92/[email protected]
# vi tdlib.go

replace "-lc++" to "-lstdc++"

# cd /project-dir
# rm -rf ~/.cache/go-build
# CC=/opt/rh/devtoolset-9/root/usr/bin/gcc CXX=/opt/rh/devtoolset-9/root/usr/bin/g++ go build

It works.

[Pichas]

for docker build

RUN sed -i 's|-lc++|-lstdc++|p' /go/pkg/mod/github.com/\!arman92/[email protected]/tdlib.go

RUN go build --ldflags "-extldflags '-static -L/usr/local/lib -ltdjson_static -ltdjson_private -ltdclient -ltdcore -ltdactor -ltddb -ltdsqlite -ltdnet -ltdutils -ldl -lm -lssl -lcrypto -lstdc++ -lz'" -o /tmp/binary main.go
