td/tdutils/generate/generate_mime_types_gperf.cpp:7:10: fatal error: 'algorithm' file not found

[maximveksler]

Hello, trying to get tdlib to compile, not very successfully so far.

I'm on Ubuntu 20.04.

I got all the basic install instructions from https://tdlib.github.io/td/build.html?language=Go, i.e.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install make git zlib1g-dev libssl-dev gperf php cmake clang-6.0 libc++-dev libc++abi-dev
git clone https://github.com/tdlib/td.git
cd td
git checkout v1.6.0
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

It failed with:

Attempts

I figured I best add sudo apt install libstdc++-10-dev, same error. Then I tried to uncomment set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -stdlib=libc++") from CMakeLists.txt, same error.

LD config:

Any help please?

[maximveksler]

I'd like to point out that switching to g++ based build system does seem to work (so far..)

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install make git zlib1g-dev libssl-dev gperf php cmake g++
git clone https://github.com/tdlib/td.git
cd td
git checkout v1.6.0
rm -rf build
mkdir build
cd build
export CXXFLAGS=""
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX:PATH=../tdlib ..
cmake --build . --target install

[levlam]

Use

sudo apt-get install clang-10

And then replace everywhere "-6.0" wirh "-10".

[maximveksler]

Thanks @levlam,

I've sudo apt remove libstdc++-10-dev

and

sudo apt update
sudo apt upgrade
sudo apt install make git zlib1g-dev libssl-dev gperf php cmake clang-10 libc++-dev libc++abi-dev
git clone https://github.com/tdlib/td.git
cd td
git checkout v1.6.0
rm -rf build
mkdir build
cd build
export CXXFLAGS="-stdlib=libc++"
CC=/usr/bin/clang-10 CXX=/usr/bin/clang++-10 cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX:PATH=../tdlib -DCMAKE_AR=/usr/bin/llvm-ar-10 -DCMAKE_NM=/usr/bin/llvm-nm-10 -DCMAKE_OBJDUMP=/usr/bin/llvm-objdump-10 -DCMAKE_RANLIB=/usr/bin/llvm-ranlib-10 ..
cmake --build . --target install

so far seems to be working.

Should I close this issue or keep it open for a fix to be applied in the branch?

[levlam]

The build instructions are already fixed in the private repository. The fix will be pushed to Github next week.

[levlam]

Fixed in master.
