I'm quite new to C++ and I aspire to learn gtkmm. I'm using linux mint 17.2 and Eclipse 3.8. When I enter:#include <gtkmm.h> the compiler will complain and give this error:
fatal error: gtkmm.h: No such file or directory
I've used synaptic and installed libgtkmm-3.0-dev and when I search for the header file locate gtkmm.h I get back the following path:
/usr/include/gtkmm-3.0/gtkmm.h
So, now if enter to eclipse #include gtkmm-3.0/gtkmm.h I get a new error: fatal error: glibmm.h: No such file or directory
locate glibmm.h
shows me this path: /usr/include/glibmm-2.4/glibmm.h.
So if I enter again: #include <glibmm-2.4/glibmm.h>
I get back the same error. fatal error: glibmm.h: No such file or directory
So what am I missing here ?
OK I think I got it. in
Project->Properties -> C/C++ Build -> Settings ->GCC C++ Compiler-> Miscellaneous
you add
`pkg-config --cflags gtkmm-3.0`
in other flags.
In GCC/C++ Linker on Miscellaneous section you add `pkg-config --libs gtkmm-3.0` in other flags.
Now is GCC C++ Compiler again, on command line pattern you move the ${FLAGS} to the end.
It's working so far here.

I get the error "gcc.exe: fatal error: cannot execute 'cc1plus'" when I want to compile any program in C++. I didn't installed the compiler Mingw-w64, downloaded the zip from winlibs.com and I copied it to "C:". Then I added to the environment variable Path.
I tried to move the library cc1plus.exe.o to the lib folder of Mingw, and used the commands gcc test.cpp -o test.exe and gcc.exe test.cpp -o text.exe.
The OS is Windows.
Thank you.
I’m a newbie to C++ and Linux. There is this code I’m playing with that requires me to install the HElib (Homomorphic encryption library and other libraries - GMP, NTL) which I did. I want to compile the code (main.cpp) that has a header file (FHE.h) in HElib. My problem is how can I link FHE.h (in HElib folder) and main.cpp (in another folder) together so that I can compile them. I have tried some commands
g++ -I/Home/HElib/src/FHE.h main.cpp -o main
Error message
main.cpp:1:17: fatal error: FHE.h: No such file or directory
compilation terminated.
Another command line
g++ -I/Home/HElib/Src/FHE.h -I/Home/SimpleFHESum-master/SimpleFHESum-master/main.cpp -o main]
Error Message
g++: fatal error: no input files
compilation terminated.
What's wrong and how can I fix this?
The -I flag adds the following directory to the include path of the compiler. This enables you to write e.g. #include "FHE.h" even though that file is not located in the same folder as the source file you're trying to compile.
Have you tried just removing the 'FHE.h' part from your -I directive?
g++ -I/Home/HElib/src ...
I use Code::Blocks IDE with wxWidgets in Debian 8.9 Jessie (x86-64).
When I use the GNU GCC Compiler everything works fine thus compiling nice wxWidgets executable for Linux.
But I need to have my program working on Windows platforms so I have to do cross-compiling.
I have installed mingw32 and followed the cross-compiling instructions given
here.
I did my wxWidgets build configuration as follows:
./configure prefix=/usr/i686-w64-mingw32 --host=i686-w64-mingw32 --enable-unicode --build=`./config.guess` --disable-shared
This is so because the MinGW compiler I have is i686-w64-mingw32, located in the folder /usr/i686-w64-mingw32, and wxWidgets version is 3.1.
My compiler set-up in Code::Blocks should be correct because I managed to do cross-compiling for simple console applications and those run properly on Windows 10.0. But when it comes to wxWidgets applications there are several problems:
The compiler gives me the error (it happens when --static is added to Other compiler options in the build options for the project):
fatal error: wx/app.h: No such file or directory|
Now since wx directory in question is in the path /usr/i686-w64-mingw32/include/wx-3.1 I added this path to the search directories for the project (the build target only for the moment). This worked fine to proceed further.
My compiler settings are: wx-config --host=i686-w64-mingw32 --static --cflags
The compiler swears again (not surprised though :-)):
fatal error: wx/setup.h: No such file or directory|
Ok I've found this one in /usr/i686-w64-mingw32/lib/wx/include/i686-w64-mingw32-msw-unicode-static-3.1, so added this path to the compiler search directories.
The linker is swearing this time (creeping on my nerves):
for the build target:
undefined reference to `wxEntry(HINSTANCE__*, HINSTANCE__*, char*, int)'|
for the release target:
undefined reference to `wxAppConsoleBase::CheckBuildOptions(char const*, char const*)'|
My linker settings are wx-config --host=i686-w64-mingw32 --static --libs
I tried hard to fix this with several different build options for the wxWidgets library but with no effect on the result. So please, someone help!
I also noticed that running ./config.guess form the wxWidgets download directory gives me x86_64-unknown-linux-gnu. Thus this mean I should use x86_64-w64-mingw32 (I have this one installed in /usr/x86_64-w64-mingw32) compiler instead i686-w64-mingw32?
So the main issue is that the command wx-config --static --cflags is not recognized in Other compiler options and wx-config --static --libs is not recognized in Other linker options.
The problem persisted even though I added the path to wx-config file in the .bashrc file from the home directory, i.e. export PATH="$PATH:/usr/i686-w64-mingw32/bin". At that time I was able to run wx-config from the terminal at any location.
To solve it I've changed the options to /usr/i686-w64-mingw32/bin/wx-config --static --cflags in Other compiler options and /usr/i686-w64-mingw32/bin/wx-config --static --libs in Other linker options. This worked as a charm.
I've added the location of libstdc++-6.dll (simply found it with a search in the file manager) in Link libraries and the flags -static and -static-libgcc in Other linker options and finally did the testing with the minimal sample as Igor suggested. Just create new console application, add minimal.cpp file to it and all of the mentioned above.
The compiler did a Minimal.exe file that I have opened successfully with wine.
Note: All the include directories I mentioned in my question were in wx-config --cflags for the compiler and wx-config --libs for the linker, so no need to add them in search directories.
I am trying to compile a piece of open source software called "SPECIES
Identification of Taxonomic Mentions in Text". I am on MacOS.
I downloaded the source code (which can be found here), moved into the directory and used the command make to compile. This is the error returned:
g++ -fpic -pthread -Wall -O3 -o organisms organisms.cxx -lm -lboost_regex
In file included from batch_tagger.h:5:0,
from organisms.cxx:3:
tagger.h:7:27: fatal error: boost/regex.hpp: No such file or directory
compilation terminated.
make: *** [organisms] Error 1
I installed the C++ boost library using brew install boostand tried the above steps again (it did not work).
I tried dropping the boost directory into the directory containing the source code (it did not work).
Any suggestions/help?
You need to tell the compiler where to find boost headers.
You need to use the include path option to specify where the boost headers can be find, use -I/path/to/boost/include.
Then include the file using #include <boost/regex.hpp> from your code.
I am trying to get the libmongocxx to run on Debian Jessie 64bit after compiling it according to the :
quickstartguide
I added the path the find command returned as the location for the libmongoc-1.0.pc file the compiler is complaining missing:
$: sudo find / -name "libmongoc-1.0.pc"
/opt/mongo-c-driver/src/libmongoc-1.0.pc
/opt/mongo-c/lib/pkgconfig/libmongoc-1.0.pc
I try to set the dependency specific in the pkg path declaration:
PKG_CONFIG_PATH=/opt/mongo-c/lib/pkgconfig c++ --std=c++11 main.cpp - o hellomongo $(pkg-config --cflags --libs libmongocxx)
But I keep getting this error given xx different tries:
Package libmongoc-1.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libmongoc-1.0.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libmongoc-1.0', required by 'libmongocxx', not found
c++: error: main.cpp: No such file or directory
c++: fatal error: no input files
compilation terminated.
I hope somebody can enligthen me.
