I'm trying to use CreateTextServices function in TextServ.h. It seem I have to link riched20.lib to project to use this function.
But when I add riched20.lib to Linker/Input/Additional Depedencies, VS say error LNK1181: cannot open input file 'riched20.lib'.
How to fix this error?
I'm using VS 2013, Win 8.1 32 bit.
Had the same issue. I think there's no lib available for recent versions of richedit/msftedit, but textserv.h provides a definition of the function, so what you can do without any need for an extra .lib is this:
// load the dll and get the function address
// PCreateTextServices is declared in textserv.h:
HMODULE h = LoadLibrary(L"msftedit.dll");
PCreateTextServices createTextServices = (PCreateTextServices)GetProcAddress(h, "CreateTextServices");
...
ITextServices svc*;
int hr = createTextServices(NULL, host, (IUnknown**)&svc);
...
svc->Release();
FreeLibrary(h);

I've tried to get an audio library statically linked to my program. I use this nimble package. To get it run, i had to build the soloud library as described here. For short after download i ran "genie --with-miniaudio-only --platform=x64 vs2017" in the "build" folder and got the source code to generate the dynamic and the static library. For now i can run the following demo program from the nimble package with the generated dll alongside:
import solouddotnim, times, os
var i, spin = 0
var sl : ptr Soloud
sl = Soloud_create()
discard Soloud_init(sl)
Soloud_setGlobalVolume(sl, 1)
var stream = WavStream_create()
discard WavStream_load(cast[ptr Wav](stream), "test.ogg")
let currentTime = epochTime()
let length = WavStream_getLength(stream)
discard Soloud_play(cast[ptr Soloud](sl), cast[ptr Wav](stream))
while epochTime() - currentTime <= length:
sleep(100)
Soloud_deinit(sl)
Soloud_destroy(sl)
Now to the static-link part. In the solouddotnim.nim file of the nimble package i use, i see this part:
when defined(windows):
const
libname* = "libsoloud.dll"
elif ...
So i simple changed the windows part to the following, re-installed the nimble-package and placed the "soloud_static_x64.lib" alongside to the "main.nim" of the testproject:
when defined(windows):
const
libname* = "soloud_static_x64.lib"
elif ...
But this doesent make it. (cant open "soloud_static_x64.lib" error when build)
Evereywhere where the constant "libname" is used there are the pragmas "cdecl", "importc" and "dynlib". For example:
proc Soloud_create*(): ptr Soloud {.cdecl, importc: "Soloud_create", dynlib: libname.}
So "dynlib" is telling nim to use a dll on windows. But was is the pragma for static libraries?
In the nim documentations i only found DynlibOverride to link to static libraries, but i dont understand the example and here is where i stuck. I've tried the followings:
nim c --dynlibOverride:libname --passL:soloud_static_x64.lib "examples\00-ogg\Example00_ogg.nim"
nim c --dynlibOverride:soloudtotnim --passL:soloud_static_x64.lib "examples\00-ogg\Example00_ogg.nim"
Firstly i dont know what parameter dynlibOverride expects and secondly both compiles, but dont work. It expects a dynamic library alongside the exe.
My last try was to remove all dynlib pragmas from the nimble package. But now i cant compile it.
undefined reference to `Soloud_create'
...
Error: execution of an external program failed: 'gcc.exe...
My knowlege ends here. Can someone help me?
Thanks in advance.
Edit:
I could not get any of your solutions work. I break down the problem as small as possible so everybody can reproduce this:
"foo.nim" contains this:
proc add*(a, b: int): int {.cdecl, exportc.} =
a + b
proc sub*(a, b: int): int {.cdecl, exportc.} =
a - b
The .lib is simply generated with this command: "nim c --app:staticlib foo.nim"
Now to use it i created a file "main.nim" with this content:
{.passL:"foo.lib".}
proc add*(a, b: int):int {.cdecl, importc.}
proc sub*(a, b: int):int {.cdecl, importc.}
echo add(10, 5)
echo sub(10, 5)
if i simply build it with "nim c -r main.nim", i get the following output and error:

Because of the multiple definition error i also tried to build foo.lib with parameter "--noMain:on", but it doesnt make any difference.
Do you have the same problem? By the way i use the current version of Nim "nim-1.5.1" and reinstalled MingW with the finish.exe from nim.
I will try to help you with the following error you have:
undefined reference to `Soloud_create'
but i will assume that you have configured your environment so you can compile your nim programs with visual studio compiler (by adding --cc:vcc to your compile command)
this is because you already seem to have visual studio 2017 and you are compiling soloud static library with it. I think this is the best option when you are compiling with one compiler both: static library and executable that will use it.
open your static library (soloud_static_x64.lib) with some text/hex editor and search for "Soloud_create". i guess you will not find anything. so why is that? because for some reason author decided to not include "C interfacing" in a static library project. so it contains only C++ symbols and not pure C symbols that are needed for our solouddotnim.nim module.
let's try to find out what .cpp file we need for that. i noticed this information on official web site of Soloud - http://sol.gfxile.net/soloud/c_api.html
so i guess we need only one file: soloud_c.cpp
let's try to just include it in SoloudStatic.vcxproj file generated by you with Genie. like this:
..
<ClCompile Include="..\..\src\c_api\soloud_c.cpp">
</ClCompile>
..
and recompile our static library. i use this command in powershell:
& 'C:\Program Files (x86)\Microsoft Visual Studio\2019\Preview\MSBuild\Current\Bin\MSBuild.exe' /p:PlatformToolset=v142`;WindowsTargetPlatformVersion=10`;Configuration=Release`;Platform=x64 .\SoloudStatic.vcxproj
but you can compile how you want. just make sure that it's architecture is really x64. you can check it with this command:
dumpbin /headers soloud_static_x64.lib | more
finally just link it with your nim file. add this line to the top:
{.link:"soloud_static_x64.lib".}
and compile nim file with this command:
nim c --cc:vcc --dynlibOverride:libsoloud.dll -r "examples\00-ogg\Example00_ogg.nim"
I have a funny problem on my machine
Windows 7 x64, using QT 5.2 for the GUI
I'm not able to start the app I always receive the error
First I thought I had a broken dll, so through some trial and error I found a solution:
I add the QT5Core.dll via enviroment path, and NOT directly to the app folder. Then the programm works. If I copy the dll back to the app Folder, Same problem as before!?!?!?1
I'm really confused, because the error only occurs on my machine?
Debugging doesn't really help,
In code, the error occures here:
MyApplication::MYApplication(int argc, char** argv, int version)
: QApplication(argc, argv, version) // <<< this call fails!
{ }
somebody can help me?
Why is the location of the qt5core.dll a problem?!?!?
UPDATE
I used the profiling function of depends and found the following behaviour:
Failing
GetProcAddress(0x76800000 [c:\windows\syswow64\KERNEL32.DLL], "CreateSymbolicLinkW") called from > "dirone\xxxx.EXE" at address 0x00FF2877 and returned 0x7688CCE9.
First chance exception 0xE06D7363 (Microsoft C++ Exception) occurred in "c:\windows\syswow64\KERNELBASE.DLL" at address 0x765CC41F.
Exception: "bad allocation"
Working
LoadLibraryW("C:\BuildPackages\QT\plugins\platforms\qwindows.dll") called from "dirtwo\QT5CORE.DLL" at address 0x66AA5154.
Loaded "c:\buildpackages\qt\plugins\platforms\QWINDOWS.DLL" at address
0x0F380000. Successfully hooked module.
somehow the path to the qwindows.dll is hardcoded into the dll (there is no environment path to this directory)
If I rename the qwindows.dll or delete it, startup failes again.
BUT the qwindows.dll is bundeld with our product. It is in a subdirectory ./platforms/
AND the files are the same (diff returns equal)
Somebody have some clue what I should try next?
Check if you already have some qt related environmental variables.
Crashes are usually due to this, remove those envronmental variables first. Check whether you have any other qt installed libraries.
it would be better if you can post the cal stacks.
Some other dlls are needed that reside in the directory of the qt5core.dll. When you add this path to the search path the dlls are found. When you simply copy the dll these dlls can not be found. You can check dependencies with the depends tool.
Candidates for the additional dlls are:
icuin51.dll and icuuc51.dll
Found the Problem:
The enviromentvariable:
QT_QPA_PLATFORM_PLUGIN_PATH=C:\BuildPackages\QT\plugins\platforms
was set to the path. If removing this variable, everything works as it should!
So I downloaded and installed Microsoft Accelerator v2 to use ParallelArrays. I have referenced it in my project but when I try and execute the code from the module in a script file I get:
"The namespace 'ParallelArrays' is not defined
I have followed the instructions on this post:
Microsoft Accelerator library with Visual Studio F#
I've added a reference to the managed version "Microsoft.Accelerator.dll" to my F# project and then added the native "Accelerator.dll" as an item in my solution and set it's 'Copy To Output Directory' to Copy Always.
Still getting the FSI error and inline error in my script file on the '#load ...' line, however the solution builds fine, and no error in the module file.
Any ideas on what I'm missing? I'm sure it's something stupid.
Thanks,
Justin
UPDATE
I tried mydogisbox's advice, which got rid of the error above, but now when I run the code in the .fsx file I get this error instead:
--> Referenced 'F:\Work\GitHub\qf-sharp\qf-sharp\bin\Debug\Microsoft.Accelerator.dll' (file may be locked by F# Interactive process)

error FS0192: internal error: F:\Work\GitHub\qf-sharp\qf-sharp\Accelerator.dll: bad cli header, rva 0
UPDATE 2
So the bad header error has dissapeared, but now I get this instead:

I found this thread on MSDN however the answers proposed as fixes on that thread barely even relate to the question.
http://social.msdn.microsoft.com/Forums/vstudio/en-US/98600646-0345-4f62-a6c5-f03ac9c77179/ms-accelerator?forum=csharpgeneral
My Direct X version is 11, and I imagine that will suffice, however I tried installing DX9 however, it tells me that a newer version is detected therefore cant install.
There are special directives for referencing dlls from fsi. The #load directive loads the .fs file only. You need to use the #r directive to reference the file. You can either use the full path of the file or you can use #I to include the path to the file. More details here. Keep in mind that fsi is completely independent of your project, so all references in your project must be duplicated in fsi for it to access the same types.
Hi I am trying to work with the rcpp. For this I want some cpp code which loads a dll by use of a lib-file (which has the same name as ). the code which I let run is:
cppFunction(includes=c("#include "windef.h","#include \"C:/data/Rdata/IHUAPI.H\" "), 'int functietom(int a){long serverhandle;int lRet;lRet = ihuConnect ( "historian1",NULL,NULL, &serverhandle ); return 5;}', verbose
= TRUE)
I get the following error:
undefined reference to `ihuConnect#16' collect2: ld returned 1 exit
status Error in inDL(x, as.logical(local), as.logical(now), ...) :
unable to load shared object
'C:/Users/user1663/AppData/Local/Temp/RtmpSW1Ki7/sourcecpp_1a04df63309/sourceCpp_26588.dll':
LoadLibrary failure:
the ihuConnect function is located in the ihuapi.lib and ihuape.dll files. In c++ in visual studio I add the lib file as added dependency and then I get rid of this error because I also sometimes get this error and then it was that I forgot to add the lib file in the compilation.
Thus My question is: how can I add this lib file as option in the compilation.
when I use dyn.load
("C:/data/Rdata/ihUAPI.dll")
and then check if it is loaded then he says yes
the problem is that getDLLRegisteredRoutines('ihUAPI', addNames = TRUE)
then it says:
data frame with 0 columns and 0 rows
so the dll seems not to contain the functions but it does when I use it from visual studio.
So please some help with lib-files and ddl-files

You missed the Rcpp FAQ entry 2.9 'Can I use Rcpp with Visual Studio ?'.
And to kill all the suspense: No, you cannot.
I am in a HUGE depression now! I spend 2 days trying to use boost.python . PLEASE guide me! I will explain what I did.
I have Winows 7 64 bit.
The Python is 64 bit 2.7.3 installed at C:\Python27_amd64.
Now, I take boost_1_54_0.zip and unzip in F: directory.
The I use cmd.
bootstrap
this creates project-config.jam. I edit it and insert
using msvc : 9.0 ;
using python : 2.7 : C:\Python27_amd64\python : C:\Python27_amd64\include : C:\Python27_amd64\libs ;
Now i do
.\b2
This process runs for 20 something minutes and I am told that boost has successfully been build.
After that I install boost binaries from http://sourceforge.net/projects/boost/files/boost-binaries/
The binaries get installed in C:\local\boost_1_54_0.
Now I want to create a General project.
Now, I use the code given for embedding python in C++ here
#include <boost/python.hpp>
#include <boost/detail/lightweight_test.hpp>
#include <iostream>
namespace py = boost::python;
using namespace std;
int main()
{
// Initialize the interpreter
Py_Initialize();
py::object main_module = py::import("__main__");
py::object main_namespace = main_module.attr("__dict__");
py::exec("print 'Hello, world'", main_namespace);
py::exec("print 'Hello, world'[3:5]", main_namespace);
py::exec("print '.'.join(['1','2','3'])", main_namespace);
}
I setup the header files and library in VC++ directories to F:\boost_1_54_0\boost_1_54_0 and F:\boost_1_54_0\boost_1_54_0\stage\lib respectively.
I also setup project-->properties-->configuration properties-->C/C++-->General-->Additional Include directories to C:\Python27_amd64\include
Likewise, I also setup project-->properties-->configuration properties--> Linker--> General to C:\Python27_amd64\libs;"C:\local\boost_1_54_0\lib64-msvc-9.0" .
Now when I compile using x64 debugger. It gives me an error
Unhandled exception at 0x00000000 in test8.exe: 0xC0000005: Access violation at location 0x0000000000000000.
I am struck since last 2 days...but thats the closest I have been since then. please help me!
So you mean a runtime error, right?
I think you should first ensure, that there is no exception thrown by boost::python itself.
First try to set the try block around you python calls with a catch(...)
If exception is caught it is most probably the boost::python::error_already_set exception.
So, you then should decode it like here
