Am I doing anything wrong?
libpcrecpp was compiled with this configuration:
../pcre3-8.35/configure --host=i586-mingw32msvc \
--enable-shared=no --enable-static=yes \
--prefix="$(readlink -m ../pcre-install)"

You have compile pcrecpp as static library and you need to define PCRE_STATIC when compiling your code, see https://github.com/vmg/pcre/blob/a257f5c7acc12e64dc2b5aa170b8e4b87dc34f83/pcreposix.h#L117
i586-mingw32msvc-g++ -std=c++11 -o test.exe -DPCRE_STATIC -Ipcre-install/include test.cpp \
pcre-install/lib/libpcre.a \
pcre-install/lib/libpcrecpp.a \
pcre-install/lib/libpcreposix.a
Without PCRE_STATIC all public functions marked as dllimport and have different name mangling

You must define PCRE_STATIC (i.e. -DPCRE_STATIC).

GMock and Undefined References Error in Qt

I'm trying google mock testing using Qt Creator in Windows, but it turns to have so many different undefined reference errors.
I tried it in Linux and it's working. I don't know if I have a wrong setup with gmock when it comes to Windows.
Here's the code with issues on MOCK_CONST_METHOD2, MOCK_METHOD2, MOCK_METHOD1, and on the first two EXPECT_CALL. And also have issues on gmock header files.

Maybe you forgot to add in your sources the ".cc" files of gmock.
Because in your .pro file, you only added the ".cc" files of gtest.
What I always do is, "add existing files" then look for the src folder of the gmock.
And add the .cc files.
Like this sample:
SOURCES += \
../calculator.cpp \
../button.cpp \
main.cpp \
gtest/src/gtest.cc \
gtest/src/gtest-all.cc \
gtest/src/gtest-death-test.cc \
gtest/src/gtest-filepath.cc \
gtest/src/gtest-port.cc \
gtest/src/gtest-printers.cc \
gtest/src/gtest-test-part.cc \
gtest/src/gtest-typed-test.cc \
gmock/src/gmock-spec-builders.cc \
gmock/src/gmock-matchers.cc \
gmock/src/gmock-internal-utils.cc \
gmock/src/gmock-cardinalities.cc \
gmock/src/gmock-all.cc \
gmock/src/gmock.cc
My new .pro file
CONFIG += console c++14
INCLUDEPATH += "google/googlemock/include/"
INCLUDEPATH += "google/googlemock/"
INCLUDEPATH += "google/googletest/include/"
INCLUDEPATH += "google/googletest/src/"
INCLUDEPATH += "google/googletest/"
INCLUDEPATH += "google/"
INCLUDEPATH += "../../"
SOURCES += \
order.cpp \
google/googletest/src/gtest.cc \
google/googletest/src/gtest-all.cc \
google/googletest/src/gtest-death-test.cc \
google/googletest/src/gtest-filepath.cc \
google/googletest/src/gtest-port.cc \
google/googletest/src/gtest-printers.cc \
google/googletest/src/gtest-test-part.cc \
google/googletest/src/gtest-typed-test.cc \
google/googlemock/src/gmock.cc \
google/googlemock/src/gmock-all.cc \
google/googlemock/src/gmock-cardinalities.cc \
google/googlemock/src/gmock-internal-utils.cc \
google/googlemock/src/gmock-matchers.cc \
google/googlemock/src/gmock-spec-builders.cc
HEADERS += \
mail_service.hpp \
order.hpp \
warehouse.hpp
I had the same issue and the pointer to include the source files for gmock and gtest is the correct lead, but I still got errors on linkage (i'm using CMake).
The error was for multiple definition of functions. The issue was that gtest-all.cc includes all the relevant sources for gtest (and gmock-all.cc does the same for gmock sources). So all you need to do is include gtest-all.cc and gmock-all.cc:
SOURCES += \
../calculator.cpp \
../button.cpp \
main.cpp \
gtest/src/gtest-all.cc \
gmock/src/gmock-all.cc
This is also much cleaner.
I hope this is a good complimentary solution for the answer above, as it solves the next issue in line (at least for me).

Linking issues Boost.Python

Trying to use Boost Python, but getting linkage issues.
Code, hello.cpp:
#include <boost/python.hpp>
char const* greet() {
return "hellow, world";
}
int main() {
return 0;
}
BOOST_PYTHON_MODULE(hello_ext) {
using namespace boost::python;
def("greet", greet);
}
Compiling with:
g++ hello.cpp -L/usr/lib/x86_64-linux-gnu/ -I/usr/include/python3.5/ -lboost_python /usr/lib/x86_64-linux-gnu/libpython3.5m.so -lboost_system
Getting the following linkage errors:

Any ideas?
Here while compiling give proper, exact and ordered path for libraries. Please use below command and try, If it doesn't work set LD_LIBRARY_PATH(set in program dir path only) to program directory path. This will link all the required library to your program directory.
g++ -I/usr/include/python3.5/ /usr/lib/x86_64-linux-gnu/libpython3.5m.so -L/usr/lib/x86_64-linux-gnu/ -lboost_python -lboost_system hello.cpp -o hello
If above line do not work
export LD_LIBRARY_PATH=/program_path:$LD_LIBRARY_PATH

gcc Linker and OGDF "undefined reference to `ogdf::Initialization::Initialization()'"

I am trying to get OGDF working to see if it is suitable for my project, but I am having trouble with a sample program.
I am trying to compile this example program:
#include <ogdf/basic/Graph.h>
#include <ogdf/basic/graph_generators.h>
#include <ogdf/layered/DfsAcyclicSubgraph.h>
using namespace ogdf;
int main()
{
Graph G;
randomSimpleGraph(G, 10, 20);
DfsAcyclicSubgraph DAS;
DAS.callAndReverse(G);
G.writeGML("test.gml");
return 0;
}
using this command:
$g++ -pthread -I ./OGDF/ -L ./OGDF/_release/ -lOGDF test2.cpp
But I get the following error
/tmp/ccbpkfdt.o: In function `main':

collect2: error: ld returned 1 exit status
I tried compiling hello world, with an include from OGDF, and I still got:
undefined reference to `ogdf::Initialization::Initialization()'
I think I am not linking properly or something?
You have to be very careful in which order you type stuff when linking with a library.
Try putting test2.cpp before -lOGDF instead, like this:
g++ -pthread -I ./OGDF/ -L ./OGDF/_release/ test2.cpp -lOGDF
You must build your program using the -DOGDF_DLL when using OGDF as a shared library.
See here: http://www.ogdf.net/doku.php/tech:defines

linking against clang/llvm 3.0 libraries

I've been playing around with clang/llvm 3.0, following the tutorial here
http://amnoid.de/tmp/clangtut/tut.html
The code in the tutorial is a bit outdated but after some modification, it compiles ok (both with clang++/g++, on Ubuntu):
#include <llvm/Support/raw_ostream.h>
#include <llvm/Support/Host.h>
#include <llvm/ADT/IntrusiveRefCntPtr.h>
#include <clang/Frontend/DiagnosticOptions.h>
#include <clang/Frontend/TextDiagnosticPrinter.h>
#include <clang/Frontend/CompilerInstance.h>
#include <clang/Basic/Diagnostic.h>
#include <clang/Basic/TargetOptions.h>
#include <clang/Basic/TargetInfo.h>
#include <clang/Basic/FileManager.h>
#include <clang/Lex/Preprocessor.h>
#include <clang/Lex/HeaderSearch.h>
using namespace clang;
int main()
{
DiagnosticOptions diagOpt;
TextDiagnosticPrinter *pTextDiagPrinter = new TextDiagnosticPrinter(llvm::outs(), diagOpt);
llvm::IntrusiveRefCntPtr<DiagnosticIDs> pDiagIds(new DiagnosticIDs);
DiagnosticsEngine *pDiagEng = new DiagnosticsEngine(pDiagIds, pTextDiagPrinter);
Diagnostic diag(pDiagEng);
LangOptions lang;
FileSystemOptions fmOpt;
FileManager fm(fmOpt);
SourceManager sm(*pDiagEng, fm);
HeaderSearch headers(fm);
TargetOptions tgtOpt;
tgtOpt.Triple = llvm::sys::getHostTriple();
TargetInfo *ti = TargetInfo::CreateTargetInfo(*pDiagEng, tgtOpt);
CompilerInstance comp;
Preprocessor pp(*pDiagEng, lang, ti, sm, headers, comp);
return 0;
}
The problem is linking, I guess the problem is library order, tried various combinations, some gives thousands of undefined symbols, the best I get is with this:
g++ -fno-exceptions -fno-rtti -fno-common \
-lclangParse -lclangSerialization -lclangDriver -lclangSema -lclangAnalysis -lclangAST -lclangFrontend \
-lclangLex -lclangBasic -lclang \
`llvm-config --cxxflags --ldflags --libs` -ldl tut1.cpp
which gives

I also followed this link Linking against clang-llvm
but seems it doesn't apply to clang 3.0.
Anybody knows how to successfully build the code, or better yet, some tool like some clang-config?
just use the LLVM flags AFTER the .o file, object file won't be linked unless
the flags are written after it. A simple makefile to show what I mean
CC=clang++
LFLAGS=`llvm-config --cppflags --ldflags --libs core`
all:
$(CC) -o out in.cc $(FLAGS)
clang driver itself links with:
-lclangFrontendTool -lclangFrontend -lclangDriver -lclangSerialization -lclangCodeGen -lclangParse -lclangSema -lclangStaticAnalyzerFrontend -lclangStaticAnalyzerCheckers -lclangStaticAnalyzerCore -lclangAnalysis -lclangIndex -lclangARCMigrate -lclangRewrite -lclangAST -lclangLex -lclangBasic
A little trick how to find it out: build clang, remove the clang binary, and run make -n.
Some linkers a sensitive to the order of -l* flags when working with static libraries. The of clang libraries seems OK, so try swapping `llvm-config --cxxflags --ldflags --libs` with clang libraries list.
If that don't help, only solution for you is what #SK-logic suggested - run make -n and look at compile command for clang target.

LEDA-6.3 library

I am a leda-6.3 library user.
I used graphwin to manipulate and display graphs, but I found that references
to graphwin methods are undefined while compiling the code although they
are declared in the LEDA/incl/LEDA/graphics/graphwin.h
So I think it is a problem of object file.
#include <LEDA/graphics/graphwin.h>
#include <LEDA/graph/graph_alg.h>
using namespace leda;
int main()
{
GraphWin gw("LEDA Graph Editor");
node u=gw.new_node(point(100,100));
node v=gw.new_node(point(100,200));
gw.new_edge(u,v);
gw.display();
gw.get_window().read_mouse();
graph& G=gw.get_graph();
G.new_node();
gw.get_window().read_mouse();
gw.update_graph();
gw.get_window().read_mouse();
return 0;
}
