I am trying to use clang as a library, but I am not sure how to link the files in the Makefile.
Trying out the ASTVisitor code from: https://clang.llvm.org/docs/RAVFrontendAction.html
Here is my Makefile for reference:
CC=g++
Includes= /usr/lib/llvm-6.0/include/
Libs= /usr/lib/llvm-6.0/lib/
CLANGLIBS=-lclangTooling -lclangFrontendTool -lclangFrontend -lclangDriver -lclangSerialization -lclangCodeGen -lclangParse -lclangSema -lclangStaticAnalyzerFrontend -lclangStaticAnalyzerCheckers -lclangStaticAnalyzerCore -lclangAnalysis -lclangARCMigrate -lclangRewrite -lclangRewriteFrontend -lclangEdit -lclangAST -lclangLex -lclangBasic -lclang
run:
LD_PRELOAD=../../llvm-project/build/lib/libclang.so ./clang_parser.out
all: clang_parser.cpp
$(CC) -I$(Includes) -L$(Libs) clang_parser.cpp -o a.out $(CLANGLIBS)
clean:
rm clang_parser.out
I have installed clang as a library i.e. done sudo apt-get install libclang-dev
I get the following error:
clang_parser.cpp:13:10: fatal error: clang/Frontend/FrontendActions.h: No such file or directory
#include <clang/Frontend/FrontendActions.h>
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
Makefile:10: recipe for target 'all' failed
make: *** [all] Error 1
Any best practices on using apt installed packages in C/C++ projects are appreciated too.
Installed a number of packages just to make sure:
sudo apt-get install libclang-dev llvm clang clang-tools
This is the compilation command for reference (it includes all libraries which may be used):
clang++ `llvm-config --cxxflags --ldflags` clang_parser.cpp $(CLANGLIBS2) `llvm-config --libs --system-libs` -g -o tool
where
CLANGLIBS2=-lclangTooling -lclangFrontendTool -lclangFrontend -lclangDriver -lclangSerialization -lclangCodeGen -lclangParse -lclangSema -lclangStaticAnalyzerFrontend -lclangStaticAnalyzerCheckers -lclangStaticAnalyzerCore -lclangAnalysis -lclangARCMigrate -lclangRewrite -lclangRewriteFrontend -lclangEdit -lclangAST -lclangASTMatchers -lclangLex -lclangBasic -lclang
Set up all .so, .a files in /usr/lib/llvm-6.0/lib as LD_LIBRARY_PATH by doing:
export LD_LIBRARY_PATH=/usr/lib/llvm-6.0/lib
ldconfig
Having gone through the process myself of creating a program that uses
Clang as a library, I thought I'd post my own working Makefile.
Key elements:
It uses a binary distribution downloaded from
https://releases.llvm.org/download.html rather than
installing through apt-get so I can control exactly
what version is in use.
Like the OP, I'm using (GNU) make rather than cmake
to minimize the mystery of what is happening.
It uses the llvm-config program to get most of the required
compile and link options. Specifically, llvm-config --cxxflags
gets the preprocessor and compilation options, and
llvm-config --ldflags --libs --system-libs gets the linker options.
I'm using the same hardcoded list of clang libraries as the OP.
I do not know a way to obtain this list other than by studying what
cmake does in an llvm source tree build. There is not anything
like clang-config to help.
The llvm libraries must come after the clang libraries.
(This is obvious in retrospect, but I wasted a fair bit of time since
the linker error messages are not easy to diagnose when dealing with
literally hundreds of unfamiliar libraries.)
For completeness, I'm using GCC-9.3.0 on Linux Mint 20.1, x86_64.

I use gstreamer in my project, and if I compile program with make - IT WORKS well.

But I wrote the same in my .pro file in Qt creator and I get an error:

I have to following two files in my project:
home/cuda_compilation_test/
main.cpp
libcudatest.cu
cuda_compilation_test.pro
I am using QtCreator with qmake for compilation. However, when I am building the project using the project file shown below, I recieve a linking error file format not recognized; treating as linker script.
It nonetheless produces two object files in the debug directory
home/build-cuda_compilation_test-Desktop-Debug/
main.o
libcudatest.o
How can I
check, that the object file is indeed correctly produced and
include the seperately compiled libcudatest.o in the main project
For further reference, this is the compiler output
g++ -m64 -o cuda_compilation_test_2 libcudatest.o main.o -L/usr/lib/x86_64-linux-gnu -L/usr/local/cuda/lib64 -lcudart -lcudatest -lQtGui -lQtCore -lpthread

Error while building/deploying project Cuda (kit: Desktop Qt 5.1.1 MinGW 32bit)
When executing step 'Make'
13:09:28: Elapsed time: 00:11.
And all issues (Can't post images due low rep): issues
If im not mistaken, then problem is with linking cuda object file (vectorAddition_cuda.o) which is compiled by nvvc.exe with cl.exe and with VS libs. Then MinGW(g++ compiler) is trying somehow link together cuda object file and c++ object file (main.o) with all libs into the executable file. g++ however doesnt know about VS runtime libs and is throwing these errors. So i guess i need somehow pass VS libs to g++.
How can i fix this?
I'm a bit confused, are you using MinGW or Visual? The title seems to state that you are using MinGW but the project file seems to use a mix of both. You can't mix those two. If you compiled (or downloaded the binary directly from NVidia) CUDA with Visual Studio 2010, you HAVE to use VS10 to compile your project, otherwise it won't work.
I never used CUDA myself but it seems that the system requirements mention only Visual Studio 2008, 2010 and 2012. If you want to use it with Qt, it's possible, you just have to grab a Qt compiled with VS (there are builds for 32 and 64 bit for both on the download page. You can get Visual Studio Express for free as long as you don't create any commercial application with it.
To use QtCreator with the MSVC backend compiler go to Tools > Options > Build and Run > Kits and add a new Kit with the MSVC compiler, cdb as the debugger and the Qt version you just downloaded (it must have been compiled with the same Visual Studio version otherwise it won't work). Then open your project, go to the Projects tab (on the left) and select the Kit you just created. You should probably clean your .pro file as well before everything work smoothly.
On a side note, there are a few things that seems out of place in your linker line:
g++ -Wl,-s -Wl,-subsystem,windows -mthreads -o release\Cuda.exe release/cuda/vectorAddition_cuda.o release/obj/main.o -lglu32 -lopengl32 -lgdi32 -luser32 -lmingw32 -lqtmain -LC:\Cuda\CudaToolkit\lib\Win32 -LC:\Cuda\CudaSamples\common\lib\Win32 -LC:\Cuda\CudaSamples\..\shared\lib\Win32 -LC:\CUDA\VS10\VC\lib -LQMAKE_LIBS -L+= -L-lmsvcrt -L-llibcmt -L-llibcpmt -lcuda -lcudart -LF:\Programs\Qt5.1.1\5.1.1\mingw48_32\lib -lQt5Gui -lQt5Core
First this -L+=, which might be caused by the escaping backslash at the end of the QMAKE_LIBDIR.
Then the syntax -L-lmsvcrt seems wrong. It might be because you are using QMAKE_LIBS, I personally never had to use it, and according to the documentation you shouldn't either as it is an internal variable. Same goes for QMAKE_LIBDIR btw. I would just use the LIBS variable for any external dependency.
You can add these to your .pro file which be used to link to CUDA on Windows using VS2010 and on Linux:
# Define output directories
CONFIG(release, debug|release): CUDA_OBJECTS_DIR = release/cuda
else: CUDA_OBJECTS_DIR = debug/cuda
# This makes the .cu files appear in your project
OTHER_FILES += vectorAddition.cu

I am trying to learn Qt, I have file test.cpp that I run via the terminal using the following command:
g++ `pkg-config --cflags --libs libsbml` test.cpp -L /usr/local/lib -lsbml -lstdc++ -lm
How can I suppl the same options to Qt?
Thank you.
You could write the qmake snippet below. In short, you would need to take a look at the following qmake variables:
LIBS
INCLUDEPATH
TEMPLATE
TARGET
HEADERS
SOURCES
CONFIG
PKGCONFIG
test.pro
TEMPLATE = app
TARGET = test
INCLUDEPATH += .
LIBS += -L /usr/local/lib -lsbml -lstdc++ -lm
unix {
CONFIG += link_pkgconfig
PKGCONFIG += libsbml
}
HEADERS += test.h
SOURCES += test.cpp
In .pro file add:
LIBS += -L /usr/local/lib -lsbml -lstdc++ -lm
look at the Makefile to figure out what variables are used. The makefile is in the build folder made by Qt.
