Is CImg compatible with Emscripten - c++

I have written a program in c++, but need to turn it to javascript to be run on an iPad. The only issue is that my program uses CImg. This is the compile command
em++ -std=c++11 -Wall -L./lib -lX11 -ljpeg -lpng -I./include -I./include/include main.cpp obj/object1.o obj/object2.o -o bin/executable.js
./include has my program header files and ./include/include has all the files that were located in /opt/X11/include which are needed to run CImg. and I get the following error:

I'm pretty sure it has something to do with linking the libraries. But I don't know if it is even possible to work with CImg while converting through Emscripten.


Any portable C or C++ codebase should work. But you do need to port all dependencies. Looks like the app uses Xlib and libpng, based on those warnings. You might need to port the X stuff to something emscripten already supports, like SDL. For png, there are a few ports around (or you can compile it yourself), e.g. https://github.com/hachque-Emscripten/libpng-1.2.49


If you don't need the X11 features of CImg (basically, if you don't want to display an image into a CImgDisplay window), then you can disable it by defining the macro cimg_display=0 while compiling your CImg-based code.

which library contains _is_c_termination_complete

I am getting LNK2019 error from linking C++ code with the standard library C++ library. I need to know which libraries contain the functions:
is_c_termination_complete,
__acrt_initialize,
__acrt_uninitialize,
__acrt_uninitialize_critical,
__acrt_thread_attach,
__acrt_thread_detach
to include it in the linking process.
I am writing code in C++ with MS Visual Studio community 2017 and Intel Parallel studio xe 2019 update 1 to be integrated in 3rd party software. The 3rd party software provides a "make" option to compile the object files and link them together.
Compilation works fine, linking provides an issue.
The 3rd party software provides an entry to provide basic linker options in the form of a variable. The default options are as follows:
link_sl='LINK', '/nologo', '/NOENTRY', '/INCREMENTAL:NO', '/subsystem:console', '/machine:AMD64',
' /NODEFAULTLIB:LIBC.LIB', '/NODEFAULTLIB:LIBCMT.LIB','/DEFAULTLIB:OLDNAMES.LIB', '/DEFAULTLIB:LIBIFCOREMD.LIB', '/DEFAULTLIB:LIBIFPORTMD.LIB', '/DEFAULTLIB:LIBMMD.LIB', '/DEFAULTLIB:kernel32.lib', '/DEFAULTLIB:user32.lib', '/DEFAULTLIB:advapi32.lib','/FIXED:NO', '/dll','/def:%E', '/out:%U', '%F', '%A', '%L', '%B',
'oldnames.lib', 'user32.lib', 'ws2_32.lib', 'netapi32.lib','advapi32.lib',
'msvcrt.lib', 'vcruntime.lib', 'ucrt.lib']
This gives the following 11 errors when linking:
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __vcrt_initialize referenced in function __scrt_initialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __vcrt_uninitialize referenced in function __scrt_initialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __vcrt_uninitialize_critical referenced in function __scrt_dllmain_uninitialize_critical
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __vcrt_thread_attach referenced in function __scrt_dllmain_crt_thread_attach
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __vcrt_thread_detach referenced in function __scrt_dllmain_crt_thread_attach
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol _is_c_termination_complete referenced in function __scrt_dllmain_uninitialize_c
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_initialize referenced in function __scrt_initialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_uninitialize referenced in function __scrt_uninitialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_uninitialize_critical referenced in function __scrt_dllmain_uninitialize_critical
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_thread_attach referenced in function __scrt_dllmain_crt_thread_attach
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_thread_detach referenced in function __scrt_dllmain_crt_thread_detach
Which basically means that I am not including all the necessary libraries.
I already found out that including the library 'libvcruntime.lib' in the options reduces the errors to 6. So, using:
link_sl='LINK', '/nologo', '/NOENTRY', '/INCREMENTAL:NO', '/subsystem:console', '/machine:AMD64',
' /NODEFAULTLIB:LIBC.LIB', '/NODEFAULTLIB:LIBCMT.LIB','/DEFAULTLIB:OLDNAMES.LIB', '/DEFAULTLIB:LIBIFCOREMD.LIB', '/DEFAULTLIB:LIBIFPORTMD.LIB', '/DEFAULTLIB:LIBMMD.LIB', '/DEFAULTLIB:kernel32.lib', '/DEFAULTLIB:user32.lib', '/DEFAULTLIB:advapi32.lib','/FIXED:NO', '/dll','/def:%E', '/out:%U', '%F', '%A', '%L', '%B',
'oldnames.lib', 'user32.lib', 'ws2_32.lib', 'netapi32.lib','advapi32.lib',
'msvcrt.lib', 'vcruntime.lib', 'ucrt.lib',**'libvcruntime.lib'**]
Results in:
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol _is_c_termination_complete referenced in function __scrt_dllmain_uninitialize_c
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_initialize referenced in function __scrt_initialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_uninitialize referenced in function __scrt_uninitialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_uninitialize_critical referenced in function __scrt_dllmain_uninitialize_critical
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_thread_attach referenced in function __scrt_dllmain_crt_thread_attach
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_thread_detach referenced in function __scrt_dllmain_crt_thread_detach
Which other libraries do I need to include in the linking process to resolve these?

I have encountered exactly the same problem when working within the framework provided by this 3rd party software. Although I cannot answer directly the question for finding the libraries containing _is_c_termination_complete, I realised it is still possible to make your code work: simply adding a /FORCE flag to your link_sl flag list.
According to MSVC official documentation:
The /FORCE option tells the linker to create a valid .exe file or DLL even if a symbol is referenced but not defined or is multiply defined.
Therefore, LNK2019 error messages will not stop the linker producing the dll library which is critical for the 3rd party software to run. The linker messages would look like:
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol _is_c_termination_complete referenced in function __scrt_dllmain_uninitialize_c
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_initialize referenced in function __scrt_initialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_uninitialize referenced in function __scrt_uninitialize_crt
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_uninitialize_critical referenced in function __scrt_dllmain_uninitialize_critical
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_thread_attach referenced in function __scrt_dllmain_crt_thread_attach
msvcrt.lib(utility.obj) : error LNK2019: unresolved external symbol __acrt_thread_detach referenced in function __scrt_dllmain_crt_thread_detach
: warning LNK4088: image being generated due to /FORCE option; image may not run
msvcprt.lib(locale0_implib.obj) : warning LNK4210: .CRT section exists; there may be unhandled static initializers or terminators
This is certainly not a decant solution and is not guaranteed to be working in any case, however it worked for my codes at least.

Why I get unresolved external errors when I want to link the release version of the static library TinyXML 2 in C++ Builder Starter?

I got a simple question. I read that linking debug static libraries to release executables is considered a bad thing. So I compiled the static library of TinyXML 2 in release mode. Library compiled without any errors. But when I want to link the release static library library with the release version of my example application I get the following output:

If I compile the application with the debug static TinyXML 2 library it compiles ok. Am I doing something wrong? I use C++ Builder 10.1 Berlin Update 2 Starter.

Looks like your issue is linked to compiler options in release mode.
Could you have a look on "Exception handling" options?
___seh_personality_v0 and __Unwind_SjLj_Register are "Exception handler" functions.

Compile FFmpeg Zeranoe Build with Visual Studio 2013

I downloaded the most recent Zeranoe dev build here, included the header files to my code, placed extern "C" around the includes, since this is a C++ project and FFmpeg is a C library, and added the libs to Visual Studio as well, and I get this linker error:

Searching here and on Google I found many recommendations, such as to add #pragma comment(lib,...), and that the libs are static, so their order is important, and none of this helps.
So I scratched my head even more and realized that the Zeranoe build is made with MinGW-w64, so probably it won't link with Visual Studio. I inspected the lib using dumpbin and the symbols on the libs don't have the underscore, so I am pretty sure it won't work.
The other Zeranoe builds for Windows don't have libs, they are just plain .exe or exe + .dll.
Will I have to make my own VS2013 build of FFmpeg to link it, or is there some alternative way?

Please how can i get rid of this?? thanks

Those missing symbols are from the Borland-C++ Compiler libraries.
Since you're using Code::Blocks add these to the Link Libraries pane on your project's build options (Menu Bar->Project Options->Linker Settings):
cw32.lib - Single Threaded
cw32i.lib - Single Threaded (Dynamic)
cw32mt.lib - Multi Threaded
cw32mti.lib - Multi Threaded (Dynamic)
