After make install via cmake - grpc forlders is empty - c++

I try to installing GRPC from sources.
I have Oracle Linux 7.9, GCC 10.2.1 from devtoolset-10 and cmake version 3.21.0-rc1 built from sources.
The way i used:
git clone --recurse-submodules -b v1.37.0 https://github.com/grpc/grpc
cd grpc
mkdir -p cmake/build
pushd cmake/build
cmake -DgRPC_INSTALL=ON \
-DgRPC_BUILD_TESTS=OFF \
-DCMAKE_INSTALL_PREFIX=$/usr/local/bin \
../..
make
make install
After this i see that files from /root/grpc/cmake/build$/usr/local/bin/lib/....files been created in /usr/local/....
Ok. But when i change directory to /usr/local - this directory does`t content files from make install.
What i doing wrong?
BTW, when i try to built 1.38 version of GRPS i return building error:
/root/grpc/src/core/lib/gpr/log_linux.cc: In function ‘void gpr_default_log(gpr_log_func_args*)’:
/root/grpc/src/core/lib/gpr/log_linux.cc:97:62: error: no matching function for call to ‘StrFormat(const char [22], const char*, char [64], int32_t&, long int&, const char*&, int&)’
time_buffer, now.tv_nsec, tid, display_file, args->line);

The following worked for me:
$ git clone --recurse-submodules -b v1.37.0 https://github.com/grpc/grpc
$ cmake -G Ninja -S grpc/ -B grpc-build \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX=/usr/local \
-DgRPC_INSTALL=ON \
-DgRPC_BUILD_TESTS=OFF
$ cmake --build grpc-build --target install
The relevant differences here are that my install prefix doesn't have a stray $ in it and that I set the build type (which you must always do).
I'm on Ubuntu 20.04 LTS using CMake 3.20.5 (the latest release) and GCC 10.3.0. Please try the above commands and see if anything changes.

Duplicate symbols when linking libwebrtc.a on Android

Building WebRTC directly is somewhat painful (& rather time consuming so not ideal in paid for CI environments) so I've opted to use some excellent precompiled static libraries released on GitHub to speed things up. This has worked perfectly for all platforms I'm targetting (Windows, MacOS, iOS, Apple TVOS, linux...) except for Android.
When linking the binary on Android I encounter several duplicate symbol errors related to the std libary:
ld: error: duplicate symbol: std::logic_error::logic_error(char const*)
>>> defined at stdexcept_default.ipp:24 (../../../../../_source/android/webrtc/src/buildtools/third_party/libc++/trunk/src/support/runtime/stdexcept_default.ipp:24)
>>> stdexcept.o:(std::logic_error::logic_error(char const*)) in archive /root/webrtc/lib/armeabi-v7a/libwebrtc.a
>>> defined at stdexcept_default.ipp:24 (/buildbot/src/android/ndk-release-r23/toolchain/llvm-project/libcxx/src/support/runtime/stdexcept_default.ipp:24)

It appears that libwebrtc.a for Android includes some libc++ object files and I'm not entirely sure how to successfully link with this library here.
This might be coming down to the libwebrtc.a being compiled with Google's own patched libc++ (Based on what I've read online I believe Google contributes patches to upstream libc++ but they don't wait for the patches to go in - rather they use their fully patched version of libc++ for building WebRTC, Chrome, etc).
When compiling for Linux I actually use the exact versions of clang & libc++ that were downloaded & used in building the static library & I suspect I might need to be doing something similar here - I'm just not entirely sure how given the need to use the Android CMake toolchain.
I've put together a minimal example project on GitHub with Dockerfile that can be used to easily reproduce the above issue.
Does anyone have an idea how I can successfully link the library on Android?
For completeness the source files of interest are:

Building LLVM toolchain Stops midway through

So I am atempting to build the ARA-RISCV build and it requires a RISC-V LLVM toolchain and they give you a "make toolchain-llvm" command and it starts off ok but midway through the build around 2500/3500 it stops and the terminal closes without pointing out any error while it builds.
The command that are used are the ones below:
mkdir -p /.../rvv/install/riscv-llvm
cd /.../rvv/toolchain/riscv-llvm && rm -rf build && mkdir -p build && cd build && \
cmake -G Ninja \
-DCMAKE_INSTALL_PREFIX=/home/alex/Documents/Project/rvv/install/riscv-llvm \
-DLLVM_ENABLE_PROJECTS="clang;lld" \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_C_COMPILER=gcc \
-DCMAKE_CXX_COMPILER=g++ \
-DLLVM_DEFAULT_TARGET_TRIPLE=riscv64-unknown-elf \
-DLLVM_TARGETS_TO_BUILD="RISCV" \
../llvm
cd /.../rvv/toolchain/riscv-llvm && \
cmake --build build --target install
After everything the build is incomplete and a lot of files have not been downloaded.I dont know what is causing this can anybody help?
Please and thank you.
EDIT:It worked by adding -j8 to the last instruction aka
cmake --build build --target install -j8

How to build Opencv code in a docker file

I want to build and run a c++ opencv code using docker. Here is my dockerfile:
FROM nvidia/cuda:11.5.0-cudnn8-runtime-ubuntu20.04
FROM ubuntu
ARG DEBIAN_FRONTEND=noninteractive
RUN apt-get update && \
apt-get install -y \
g++ git wget cmake sudo
RUN apt-get install -y \
build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev \
python3-dev python3-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libdc1394-22-dev \
libcanberra-gtk-module libcanberra-gtk3-module
RUN git clone https://github.com/opencv/opencv.git && \
cd /opencv && mkdir build && cd build && \
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local .. && \
make -j"$(nproc)" && \
make install && ldconfig
The above commands makes my opencv libs, but I don't how to use it to run the actual code. I added this two lines at the end of the dockerfile (wav.cpp is the name of my cpp file that I want to run):
COPY . .
RUN g++ -o wav wav.cpp
But at the end I get this error, which obviously says it can't find the opencv headers.
wav.cpp:2:10: fatal error: opencv2/imgproc.hpp: No such file or
directory
2 | #include "opencv2/imgproc.hpp"
| ^~~~~~~~~~~~~~~~~~~~~ compilation terminated.
Now how should I resolve this header (and lib) dependency problem?
Thank you.
You didn't specify the location for the headers and which libraries should be linked by gcc. Please take a look at the manual of gcc/g++ for the flags -I and -L. Should be something like this:
RUN g++ -o wav wav.cpp -I <opencv header location> -L <opencv libs location> -lopencv_core ....
Using #emrhzc's answer I could build my code inside the dockerfile. Now my final working command is:
RUN g++ -o wav wav.cpp `pkg-config --cflags --libs opencv4`

Could NOT find Protobuf (missing: Protobuf_PROTOC_EXECUTABLE)

When I am doing a cmake in the build directory of the project I am getting this error. Initially I got a
protobuf-config.cmake not found
error. So I gave a path of the protobuf-config.cmake file to Protobuf_DIR. Later it started to show this new error:
CMake Error at
/opt/cmake/share/cmake-3.13/Modules/FindPackageHandleStandardArgs.cmake:137
(message): Could NOT find Protobuf (missing:
Protobuf_PROTOC_EXECUTABLE)
(found suitable version "3.6.1", minimum required is "3.0.0")
I am also attaching the error log file:
https://drive.google.com/open?id=1y7BZ6lDBtxvla7r-o188xM_FjwLqwhCx
I am doing this on Ubuntu-18 with cmake version: 3.13 and protobuf version: 3.6.1
You probably don't have the Protobuf compiler and development files installed. To fix that, run this command:
sudo apt-get install protobuf-compiler libprotobuf-dev
Alternatively, if you're building Protobuf by hand, you can't build it with the build type as RelWithDebInfo because that causes issues with the library and CMake.
Installed from apt on Ubuntu 20.04, dont have permissions to /usr/include/google
To fix: sudo chmod +Xr -R /usr/include/google
Default repositories usually contain outdated protobuf version. It is best to install it manually, from sources:
git clone --progress -b v3.10.0 https://github.com/protocolbuffers/protobuf && \
( \
cd protobuf; \
mkdir build; \
cd build; \
cmake ../cmake \
-DCMAKE_BUILD_TYPE=Release \
-Dprotobuf_BUILD_SHARED_LIBS=ON \
-Dprotobuf_BUILD_TESTS=OFF; \
make -j4 install; \
) && \
rm -rf protobuf
Quickly adding here that after installing Protobuf following this answer, I had to delete the build folder in my workspace to get cmake to run without this error :)
Hy,
list your protobuf libraries with sudo apt list | grep protobuf it should tell you what it will install by default. Run protoc --version so that you see what is recognized by default now. And after that get a version from github if needed build it and install it (this should not take to long). Then run protoc --version again.

How to build the latest clang-tidy?

I've tried to build clang-tidy from sources but it complains about an undefined CMake command:
CMake Error at clang-apply-replacements/CMakeLists.txt:5 (add_clang_library):
Unknown CMake command "add_clang_library".
CMake Warning (dev) in CMakeLists.txt:
No cmake_minimum_required command is present. A line of code such as
cmake_minimum_required(VERSION 3.9)
should be added at the top of the file. The version specified may be lower
if you wish to support older CMake versions for this project. For more
information run "cmake --help-policy CMP0000".
This warning is for project developers. Use -Wno-dev to suppress it.
-- Configuring incomplete, errors occurred!
How can I build clang-tidy or, alternatively, how can I install the latest version on macOS?
Up-to-date steps:
git clone https://github.com/llvm/llvm-project.git
cd llvm-project
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" ../llvm
make install clang-tidy
Reference, ninja, and other details: my own blog post.
EDIT: this answer is out of date — the LLVM project has moved to a single git repository at https://github.com/llvm/llvm-project. See answers below for updated instructions.
clang-tidy is intended to be built inside a checkout of llvm/clang, and depends on CMake macros from the llvm project. You should check out the llvm repo, then the clang repo inside llvm/tools/clang, then the clang-tools-extra repo inside llvm/tools/clang/tools/extra. Then you can run CMake on the top-level directory, and make clang-tidy should work.
If you're not interested in building it yourself, it looks like the Homebrew formula for LLVM also includes the extra tools: https://github.com/Homebrew/homebrew-core/blob/382d3defb5bc48ce2dccd17261be70c4ada9a124/Formula/llvm.rb#L181
I had same problem as Per Mildner. Got is solved with slightly modified code YvesgereY posted (I don't have enough reputation to post a comment to that answer, hence a new answer instead).
In short, I added -G "Unix Makefiles" to cmake. Without this option, no makefile will be generated. Also, I used -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra;". It didn't work when just clang-tools-extra was specified.
Here is the whole snippet:
git clone https://github.com/llvm/llvm-project.git
cd llvm-project
mkdir build
cd build
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=RelWithDebInfo -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra;" ../llvm
make -j8 install-clang-tidy
#jtbandes: Thank you for the information.
I'd like to share these explicit steps for us noobs:
1. Download the released sources from LLVM Download Page
LLVM source code -> Links to the file llvm-6.0.0.src.tar.xz
Clang source code -> Links to the file cfe-6.0.0.src.tar.xz
clang-tools-extra -> Links to the file clang-tools-extra-6.0.0.src.tar.xz
2. Detar each of these into the proper directory:
$ tar -zxvf <download_dir_path>/llvm-6.0.1.src.tar.xz
$ cd llvm-6.0.1.src/tools
$ tar -zxcf <download_dir_path>/cfe-6.0.1.src.tar.xz
$ cd llvm-6.0.1.src/tools/cfe-6.0.1.src/tools
$ tar -zxvf <download_dir_path>/clang-tools-extra-6.0.1.src.tar.xz
Results in a directory llvm-6.0.1.src/tools/cfe-6.0.1.src/tools/clang-tools-extra-6.0.1.src/clang-tidy; Which is incorrect. The lang-tools-extra-6.0.1.src needs to be renamed to extra (as mentioned by #jtbandes).
3. So rename it or provide a symbolic link:
$ cd llvm-6.0.1.src/tools/cfe-6.0.1.src/tools
$ mv clang-tools-extra-6.0.1.src extra
or
$ ln -s clang-tools-extra-6.0.1.src extra
The path llvm-6.0.1.src/tools/cfe-6.0.1.src/tools/extra/clang-tidy should now be valid
4. Build it:
$ cd llvm-6.0.1.src
$ mkdir build
$ cd build
$ cmake ..
$ make
Everything should make without errors or warnings.
5. Build Output:
The build output can be found in llvm-6.0.1.src/build/bin.
For everyone who are looking for latest (LLVM 11) Windows build instructions (ensure CMake, Visual Studio 2019 and git are installed and set in PATH):
git clone --config core.autocrlf=false https://github.com/llvm/llvm-project.git
cd llvm-project
mkdir build
cd build
cmake -G "Visual Studio 16 2019" -Thost=x64 -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" ../llvm
cmake --build . --target clang-tidy --config RelWithDebInfo --parallel
cmake --build . --target clang-query --config RelWithDebInfo --parallel
This worked for me:
mkdir build
files="
llvm-12.0.1.src.tar.xz
clang-12.0.1.src.tar.xz
clang-tools-extra-12.0.1.src.tar.xz
"
for f in $files; do
echo "Untar $f"
tar xf $f
done
mv llvm-12.0.1.src llvm
mv clang-12.0.1.src llvm/tools/clang
mv clang-tools-extra-12.0.1.src llvm/tools/clang/tools/extra
cd build
cmake -G "Unix Makefiles" \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX=/usr/local/llvm \
-DCLANG_BUILD_TOOLS=ON \
../llvm
make -j16 install
As of LLVM 14.0.0, sparse checkouts do no longer work (at least temporarily) and the top-level directory contains no CMakeLists.txt. I believe the tree layout has changed after LLVM 13.0.1. In consequence, none of the approaches here worked without quite some modification.
Here is how you can build version 15.0.0git (the most recent at the time of this writing). See related issue: https://github.com/llvm/llvm-project/issues/53281.
First, get the compressed code or clone with git (slower)
$ wget "https://github.com/llvm/llvm-project/archive/refs/heads/main.zip" -O llvm.zip
$ unzip llvm.zip
As usual, create a build directory and run cmake in the llvm directory.
$ mkdir /build
$ cd /build
$ cmake -G "Unix Makefiles" \
-DCMAKE_INSTALL_PREFIX=/usr/local/llvm \
-DCMAKE_BUILD_TYPE=Release \
-DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" \
/llvm-project-main/llvm
Navigate downwards in the generated files and only build clang-tidy.
$ cd /build/tools/clang/tools/extra/clang-tidy
$ make install
Cmake will install to /usr/local/llvm. Also, if you want to check out a specific version, use tags in the first step like this:
$ wget "https://github.com/llvm/llvm-project/archive/refs/tags/llvmorg-14.0.0.zip"
Note that you need to supply the matching builtin headers for running clang-tidy, which are located in GitHub under llvm-project/clang/lib/Headers and can by pointed to with -extra-arg=-I/path/to/builtin/headers.
