Hi, I am using Xcode 4 and trying to set up FLTK 1.3.0 to run Bjarne
Stroustrup's Chapter 12 FLTK Demo at the end of the chapter. I keep
getting the following error when compiling, and have no idea where to go.
I have an idea it might have to do with the linker flags, but I don't know
what flag to add and where...
Here's the error:
Undefined symbols for architecture x86_64:
"Fl_JPEG_Image::Fl_JPEG_Image(char const*)", referenced from:
Graph_lib::Image::Image(Point, String,
Graph_lib::Suffix::Encoding) in Graph.o
"Fl_GIF_Image::Fl_GIF_Image(char const*)", referenced from:
Graph_lib::Image::Image(Point, String,
Graph_lib::Suffix::Encoding) in Graph.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
Are you passing the linker flags present with --use-images? try:
> fltk-config --use-images --ldflags
and check the results to make sure you're getting either the system image libs, or the ones optionally built with fltk.
I also found this to be quite useful:
fltk-config --compile test.cpp
It worked perfectly for me.
For more examples of using fltk-config check out http://www.fltk.org/doc-1.1/basics.html

I have seen similar issues on here which has led me to believe i need to link binary files with library. However, i cannot figure out which ones i need, can any one help me with this ? I have macOS catalina 10.15.3, xcode 10.3, gamemaker 2.2.5.481 and runtime v2.2.5.378
here is my error message:

Bluetooth gamepad support is added in iOS 13, which requires XCode 11 to work; you probably only need to upgrade xcode.

I'm using Xcode 6.0.1 and need to add a library libpt.a to my C project. I cannot figure out how to properly integrate it into my project. I have already done Link Binary With Libraries however I still continue to get this error:
Undefined symbols for architecture x86_64:
"_pt_add_xpage", referenced from:
_main in main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I am assuming that the above error means that the library has not been integrated correctly. I have already added the header file pt.h and included into my project. What am I doing wrong?
I used Xcode to build a example of boost, but as you see followed it is failed. And the error
I've got is:
Undefined symbols for architecture x86_64:
"boost::system::system_category()", referenced from:
___cxx_global_var_init2 in sync_client.o
boost::asio::error::get_system_category() in sync_client.o

___cxx_global_var_init1 in sync_client.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I don't know how I can fix it. I've added the include and libs path of boost into Xcode Build Setting. Does anyone have any idea about this problem?
Either link against a pre-built version of libboost-system.so or pull in libs/system/src/error_code.cpp (from your boost source package), into your project.
I have been using OpenCV for a while and also the imwrite function, but unfortunately this is not working any more.
I am running with OpenCV 2.4.3 with following sample code:
imwrite("somepath/somefile.png", myMat);
The error:
Undefined symbols for architecture x86_64:
"cv::imwrite(std::string const&, cv::_InputArray const&, std::__debug::vector<int, std::allocator<int> > const&)", referenced from:
MyProject::this_callback(int, void*) in MyProject.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The error looks somewhat familiar but i cannot determine whats wrong.
Yes, I've thought you were using XCode. I had the same problem. :)
If you change the project setup so that:
you use GNU++11 as C++ language dialect
libstdc++ (GNU C++ standard) as C++ standard library
your linking problem will go away.
I use Apple LLVM 4.1.
When I had this problem, I have tried just adding a new target to one of my old projects I knew, worked. Then I've just made that target a one-source-file program.
This must be a "magic" part of XCode as I think there was a time I could not get the same project working after a restart. :S
I did what Barnabas did and also got the issue on cvdef.h. I was getting desperate so and what I did was just changed the header file.
in /usr/local/cvdef.h line 205:
I changed
include <cstdint>
typedef std::uint32_t uint;
to:
include <tr1/cstdint>
typedef std::tr1::uint32_t uint;
based on this post
I think opencv devs should apply some changes to the code for 64bit..
use something like clang version 3.8.0 (trunk 257459), instead of gcc version 4.9.2 (MacPorts gcc49 4.9.2_1+universal) to compile
for reference, cmd: clang++ -std=c++11 `pkg-config --cflags --libs opencv` code.cpp -o code

As stated by the question , When trying to build my firebreath project which requires libgpgme on MacOSX 10.6 using Xcode I get the error above. My include/search paths are valid since I can run the following command from the console and it works fine.
g++ -o test test.cpp `gpgme-config --libs`
The output form the gpgme-config is -L/opt/local/lib -lgpgme -lassuan -lgpg-error. Not sure what other info is needed , comment and I will updated as needed.
Your problem is that you're building a universal binary for both 32 and 64 bit and the library you're including is not built for 64 bit. You can build i386 only by adding -D CMAKE_OSX_ARCHITECTURES="i386" to your prepmac.sh command-line.
Make sure to delete your build directory before running prepmac.sh with the new argument or it may not take.
See the Prep Scripts page on firebreath.org for more info.
