I am trying to compile The example of Blocking TCP echo client: using the Boost.build b2 command as following:
b2 linkflags=-lpthread toolset=gcc threading=multi link=static
But I am getting the following errors:

I already have a JamFile with the contents:
install install

;
project lte_sim
;
exe lte_sim
: Simulator_main.cpp
/boost//program_options
;
So what is the solution for the problem?
Thanks a lot.
I tried "b2 linkflags=-lboost_system toolset=gcc" and I got the following errors

This question already has an answer here:
Linking issue with GCC 4.6.1
(1 answer)
Closed 1 year ago.
I wanted to build a gtest project on linux using just a makefile, ie not using cmake. I followed along the tutorial here:
http://www.yolinux.com/TUTORIALS/Cpp-GoogleTest.html
But getting multiple definition of main errors - see below.
I am on ubuntu v20.04
angus#angus-VirtualBox:~/Documents/code/gtest_make_only/test/src$ uname -a
Linux angus-VirtualBox 5.11.0-38-generic #42~20.04.1-Ubuntu SMP Tue Sep 28 20:41:07 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
I installed gtest like this:
git clone https://github.com/google/googletest.git
mkdir build
cd build
sudo snap install cmake --classic
cmake .. -DBUILD_GMOCK=OFF
make
sudo make install
If I now look on my system I have
/usr/local/include - with gtest directory with header files
/usr/local/lib - contains libgtest.a and libgtest_main.a
I modified the Makefile in the example to be like this:
CXX = g++
CXXFLAGS = -g -L/usr/local/lib -lgtest -lgtest_main -lpthread
INCS = -I./ -I../../src -I/usr/local/include
OBJS = ../../src/Addition.o Addition_Test.o ../../src/Multiply.o Multiply_Test.o
testAll: $(OBJS)
$(CXX) $(CXXFLAGS) $(INCS) -o testAll Main_TestAll.cpp $(OBJS)
.cpp.o:
$(CXX) $(CXXFLAGS) -c $< -o $# $(INCS)
clean:
rm testAll *.o testAll.xml
I also had to tidy up the code sample - eg where in code has Addition.h - have to change to Addition.hpp which is the filename.
The build error below. How to fix this?
I did try by removing -lgtest_main from the Makefile, but then get error:
/home/angus/Documents/code/gtest_make_only/test/src/Main_TestAll.cpp:5: undefined reference to `testing::InitGoogleTest(int*, char**)'

Your command lines are all wrong.
Library specification should follow sources and object files. Correct line should look like this:
g++ -g -I./ -I../../src -o testAll Main_TestAll.cpp ../../src/Addition.o Addition_Test.o ../../src/Multiply.o Multiply_Test.o -lgtest_main -lgtest -lpthread

You have not linked the executable against several libraries that are required by the program
Try using this:
g++ -lpthread `pkg-config opencv --libs` -I/usr/local/include/ -lraspicam -lraspicam_cv -L/opt/vc/lib -lmmal -lmmal_core -lmmal_util -I/usr/include -lwiringPi test3.cpp -o test3
I am trying to test boost python with example in official website.
But It incurs so many errors...
The below is my what i did and the errors.
Download Boost1.55 with this.
Add Eclipse library search path to "usr/includ" (boost directory place at here)
Add library flag -lpython2.7 (Python2.7 is installed)
Add include path usr/include/python2.7(at my first try, the error happen : couldn't find pyconfig.h)
And this is my test code i did, and errors, the test code was only to see if it is compiled normally with boost python.
#include <iostream>
#include <boost/python.hpp>
char const* greet()
{
return "hello, world";
}
BOOST_PYTHON_MODULE(hello_ext)
{
using namespace boost::python;
def("greet", greet);
}
int main(){
std::cout << "aaa" << std::endl;
}
.
The Error part denoted with redline in eclipse is BOOST_PYTHON_MODULE(hello_ext)

I added two additional flags for boost and then it works !!
-lboost_python -lboost_system
I am absolutely horrible with compiling/linking.
I have tried everything i could find, nothing works.

QFS provides .so and .a of
libqfs_client
libqfs_qcdio
libqfs_io
libqfs_common
libqfs_qcrs
How do i build my wrapper (cqfs.cpp, cqfs.h)?
This is my current command:
g++ -Wall -DBOOST_SP_USE_QUICK_ALLOCATOR -shared -o libcqfs.so cqfs.cpp cqfs.h -fPIC -L./libqfs_client.so -L./libqfs_qcdio.so -lpthread -lrt -L./libqfs_io.so -L./libqfs_common.so -L./libqfs_qcdio.so -lpthread -lz -lrt -lboost_regex-mt -lcrypto -L./libqfs_qcrs.so -lc
based on the example application(not library) provided by Quantcast:
c++ -Wall -DBOOST_SP_USE_QUICK_ALLOCATOR -g CMakeFiles/qfssample.dir/qfssample_main.o -o qfssample -rdynamic ../../src/cc/libclient/libqfs_client.a ../../src/cc/qcdio/libqfs_qcdio.a -lpthread -lrt ../../src/cc/kfsio/libqfs_io.a ../../src/cc/common/libqfs_common.a ../../src/cc/qcdio/libqfs_qcdio.a -lpthread -lz -lrt -lboost_regex-mt -lcrypto ../../src/cc/qcrs/libqfs_qcrs.a
.a or .so did not make a difference
It looks like you are incorrectly using the -L argument to g++. The argument of -L should refer to the directory that contains the libraries, rather than directly referencing them.
To demonstrate, I created a simple example with a Connect and Readdir (I've omitted it for brevity, but let me know if you want to see it). Here is the c++ command I crafted to get it to compile and link correctly:
c++ -Wall -o t -I./build/release/include -L./build/release/lib t.cc -lqfs_client -lqfs_common -lqfs_io -lqfs_qcdio -lqfs_qcrs -lpthread -lboost_regex-mt -lz -lcrypto
One can then run it by specifying the LD_LIBRARY_PATH (DYLD_LIBRARY_PATH on Max OS X):
DYLD_LIBRARY_PATH=$PWD/build/release/lib ./t
.
..
dumpster
test
test2
test3
user
Note that you'll have to LD_LIBRARY_PATH instead of DYLD_LIBRARY_PATH on Linux.
We are actually working on building C bindings for QFS in the main project. Here is the pull request. If you're not comfortable with working directly from the fork (they are very experimental), you can check it out and build with make VERBOSE=1 to see the commands that are actually used to build the components and apply that to build your own bindings.
UPDATE: The C bindings for the QFS API are now available in the master branch.
For example, here is the line that is output to build the shared library on my mac:
/usr/bin/c++ -I/opt/local/include -Wall -DBOOST_SP_USE_QUICK_ALLOCATOR -O2 -g -shared -o libqfsc.dylib -install_name /Users/sday/c/qfs/build/release/src/cc/qfsc/libqfsc.dylib CMakeFiles/qfsc-shared.dir/qfsc.o ../libclient/libqfs_client.dylib ../kfsio/libqfs_io.dylib ../common/libqfs_common.dylib -lpthread -lz ../qcdio/libqfs_qcdio.dylib /usr/local/lib/libboost_regex-mt.dylib /usr/local/lib/libboost_system-mt.dylib ../qcrs/libqfs_qcrs.dylib -lcrypto
