I'm having trouble linking with Pantheios on Linux with gcc4.6 with the following error:
In function `pantheios::internal::log_dispatch_3(int, unsigned int, char const*, unsigned int, char const*, unsigned int, char const*)':
sig_writing_sink.cpp:(.text._ZN9pantheios8internal14log_dispatch_3EijPKcjS2_jS2_[pantheios::internal::log_dispatch_3(int, unsigned int, char const*, unsigned int, char const*, unsigned int, char const*)]+0x6d): undefined reference to `pantheios_log_3_no_test'
collect2: ld returned 1 exit status
I'm linking with:
libpantheios.1.core.gcc46.mt.a
libpantheios.1.fe.simple.gcc46.mt.a
libpantheios.1.be.fprintf.gcc46.mt.a
libpantheios.1.bec.fprintf.gcc46.mt.a
libpantheios.1.util.gcc46.mt.a
libpantheios.1.appl.gcc46.mt.a
libpantheios.1.core.gcc46.mt.a
Where is pantheios_log_3_no_test?
What am I missing?
Turns out that in gcc, symbols are only linked forward, so dependent symbols in a given lib will only be resolved from the libs that follow it in the link list. See here for some more details.
By moving other statically linked libs to before Pantheios, the linker succeeded.

I have been struggling with Google protobufs lately. I have written a proto file called Button.proto.
Here are its contents:
syntax = "proto3";
package robotjoystick;
message Button {
string name = 1;
int32 id = 2;
uint32 state = 3;
}
I successfully compiled it with this command (with the $USER replaced with the acctual computer user):
protoc -I=/home/$USER/robotjoystickserver --cpp_out=/home/$USER/robotjoystickserver/proto_classes Button.proto
I am using protobuf version 3.7.1.
My *.cpp file is calleddumbprrotos.cpp and it is not compiling for some reason.
Here is my *.cpp file:

thebutton.set_id(12);

}
The 2 sections of code I have labeled are 2 versions of the same thing that I am trying to accomplish, but both are throwing the same type of error and I have no idea how to interpret it. What do I need to do to make this code compile?
I should also mention that I installed protobuf 3.7.1 right off of my home directory (meaning that the zip file for protobuf was extracted there and then installed there).
The error I get when I currently run the code, the exact way it is, I get this error:

I think that is everything I need to show you guys. Did I miss anything? What do I need to do to make my *.cpp code compile?
I am on Ubuntu 16.04.
After thinking about the comment provided by #goduk, I thought I should look further into the linking library issue and find the files I need to source. It turns out that I was not linking to any specific location.
I decided to look through the docs under protobuf-3.7.1/src/README.md to explore further to find the .../lib/ directory. After re-reading those docs, a specific section caught my eye.
To compile a package that uses Protocol Buffers, you need to pass
various flags to your compiler and linker. As of version 2.2.0,
Protocol Buffers integrates with pkg-config to manage this. If you
have pkg-config installed, then you can invoke it to get a list of
flags like so:
pkg-config --cflags protobuf # print compiler flags
pkg-config --libs protobuf # print linker flags
pkg-config --cflags --libs protobuf # print both
For example:
c++ my_program.cc my_proto.pb.cc `pkg-config --cflags --libs protobuf`
On my laptop, the command pkg-config --cflags --libs protobuf returns -pthread -I/usr/local/include -L/usr/local/lib -lprotobuf -pthread.
Instead of trying to determine the correct compiling flags, I simply needed to call the required flags using pkg-config --cflags --libs protobuf at the end.
I had never heard of pkg-config before, but this solved all of my problems.
The final bash script line is now this:
g++ dumbprotos.cpp proto_classes/Button.pb.cc -o ./pleasework -std=c++11 -lSDL2 `pkg-config --cflags --libs protobuf`
Thanks for the help.
(This is a linker type issue.)
I should also mention that, if the protobuf object contains other protobuf objects, you have to include those in the command line call:
g++ my_program.cc my_proto_imported.pb.cc my_proto_containing.pb.cc `pkg-config --cflags --libs protobuf`
Meaning that my_proto_imported.pb.cc is a protobuf imported and used in my_proto_contained.pb.cc.

Does anyone have any suggestions on how to fix this?
The reason is maybe you have compiler gcc5 or gcc6.
And your code has used different compile flag with your boost library.
Detail please read this link
If you can recompile all incompatible libs you use, do it with compiler option
-D_GLIBCXX_USE_CXX11_ABI=1
and then rebuild your project. If still can not link, add change project's makefile compiler option to 0.
-D_GLIBCXX_USE_CXX11_ABI=0
======Update=======
The real solution should be install the new boost libraries (v1.62) for gcc6 or gcc5.
I am doing a pet project and am using clang++ (specifically MacPorts clang 3.1). So I decided to switch over to libc++ (to use std::array and such) but I was using boost (specifically asio and regex), so I had to recompile boost using libc++. I removed boost which was installed in macports and build boost from source and now is installed in /usr/local/include and /usr/local/lib. Ever since then, I cannot compile. Here are the oddities I am encountering:
When executing:
clang++ -g -std=c++11 -stdlib=libc++ -c main.cpp
I get a weird compile error having to do with the move constructor (there's more to this error, but as you can see it is coming from boost):
/usr/include/c++/v1/string:1952:10: error: overload resolution selected implicitly-deleted copy assignment operator
__r_ = _STD::move(__str.__r_);
^
/usr/include/c++/v1/string:1942:9: note: in instantiation of member function 'std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >::__move_assign' requested here

s1 = traits_inst.transform(a, a + 1);
However, when I execute (please note the "-I", and it must be in that exact position):
clang++ -I -std=c++11 -stdlib=libc++ -g -c main.cpp
This compiles (but linking fails later on). Why is this? What does -I do without a path? Must -stdlib= be preceded with -I?
Now the fun part:
Even though, everything compiles now, it won't link. When executing:
clang++ main.o FTPClient.o FTPConnection.o -lboost_system -lboost_regex -std=c++11 -stdlib=libc++ -g -o cli
I get the message:

Now I am thinking maybe I a missing some -lboost flag but I am not sure what it is. What could be the reason for this?
Thanks very much!
EDIT: When looking through the logs of installing boost, I noticed this:

Does this mean boost regex maybe incompatible with -libc++?
EDIT 2: I tried using std::regex, but I get this:

A helpful, but unsatisfactory answer: libc++ contains std::regex, which you can use instead of boost::regex.
Error: " Undefined symbols for architecture x86_64:

I tried running the exact same code on Visual Studio 2010, and it worked! Any idea why it doesn't work here? My Mac is 64bit. Thanks!
Here's the code on the files that's giving the error:
#include <iostream>
using namespace std;
int p,q;
int f( int, int,const int [][8],const int [][8], int [],int []);
This happens if you haven't provided an implementation of your f(..) function.
In your main.cpp file, simply implement the function, like:
int f( int, int,const int [][8],const int [][8], int [],int [])
{
// Do stuff...
}
