i have a problem with resources in my audio plugin
here is my resource file
// Unique IDs for each image resource.
#define BCKG_ID 101
#define CANT_ID 102
#define COM10_ID 103
#define COM20_ID 104
#define COM40_ID 105
#define COM80_ID 106
#define SAVE_ID 107
#define WAIT_ID 108
#define ONOFFBYPASS_ID 109
#define ONOFFPRESSED_ID 110
// Image resource locations for this plug.
#define BCKG_FN "resources/img/background.png"
#define CANT_FN "resources/img/cant.png"
#define COM10_FN "resources/img/combo10.png"
#define COM20_FN "resources/img/combo20.png"
#define COM40_FN "resources/img/combo40.png"
#define COM80_FN "resources/img/combo80.png"
#define SAVE_FN "resources/img/savwav.png"
#define WAIT_FN "resources/img/waiting.png"
#define ONOFFBYPASS_FN "resources/img/onoff-bypass.png"
#define ONOFFPRESSED_FN "resources/img/onoff-pressed.png"
i have an assert issue : "file not found" when using this code :
IBitmap onoff1 = pGraphics->LoadIBitmap(ONOFFBYPASS_ID, ONOFFBYPASS_FN, 1);
if i use WAIT_ID instead of ONOFFBYPASS_ID, everything works
in debug assert this code raises a flag:
IBitmap IGraphics::LoadIBitmap(int ID, const char* name, int nStates, bool framesAreHoriztonal)
{
LICE_IBitmap* lb = s_bitmapCache.Find(ID);
if (!lb)
{
lb = OSLoadBitmap(ID, name);
#ifndef NDEBUG
bool imgResourceFound = lb;
#endif
assert(imgResourceFound); **//imgResourceFound = false**
s_bitmapCache.Add(lb, ID);
}
return IBitmap(lb, lb->getWidth(), lb->getHeight(), nStates, framesAreHoriztonal);
}
i tried to :
switch ID values (109 <-> 108)
change the names
check 10 times the paths
but nothing works
it doesn't makes sense, especially because i have 2 other audio plugins with the same part of code that are working ok...
sorry can't provide sample code as it would mean installing VST SDK, WDL-OK...so a bit too much i guess.
please help anyway
Jeff
oh i made a noob error: i forget to add
ONOFFBYPASS_ID PNG ONOFFBYPASS_FN
ONOFFPRESSED_ID PNG ONOFFPRESSED_FN
to MyProg.rc
now everything works

This question already has answers here:
What is an undefined reference/unresolved external symbol error and how do I fix it?
(39 answers)
Closed 3 years ago.
I'm working on an implementation of an EST(Enrollment over Secure Transport)-client over CoAPs for the OpenThread stack. For this, i want to write a CSR (Certificate Signing Request) by using mbedTLS, which is part of the stack as a third party software. My problem now is that i get some "undefined reference" error from the linker when i build the code (i'm using GCC on an Ubuntu 18.04.2 LTS machine).
As there are multiple functions for which the error occurs, i will provide code for just one example. here is my source file:

I first thougth it was because i was missing some #define to actually use these functions, but i compared it with other OpenThread code which uses mbedtls and i can't see what i did wrong. As far as i've understood it, i have to modify the "openthread/third_party/mbedtls/mbedtls-config.h" file so that these funtions are build, so this is what i did:

It resolved the "not defined in this scope" errors i've had before, but instead i have now the above described errors.
Here is what i've edited in the common-switch file:
openthread/examples/common-switches.mk
ECDSA ?= 0
// my code begin
EST_CLIENT ?= 0
// my code end
JAM_DETECTION ?= 0
ifeq ($(ECDSA),1)
configure_OPTIONS += --enable-ecdsa
endif
// my code begin
ifeq ($(EST_CLIENT),1)
configure_OPTIONS += --enable-est-client --enable-application-coap-secure
endif
// my code end
ifeq ($(JAM_DETECTION),1)
configure_OPTIONS += --enable-jam-detection
endif
and her what i've added to configure:
openthread/configure.ac
#
# EST Client
#
AC_ARG_ENABLE(est_client,
[AS_HELP_STRING([--enable-est-client],[Enable EST client support #<:#default=no#:>#.])],

enable_est_client=${enableval}
;;

AC_MSG_ERROR([Invalid value ${enable_est_client} for --enable-est-client])
;;
esac
],
[enable_est_client=no])
if test "$enable_est_client" = "yes"; then
OPENTHREAD_ENABLE_EST_CLIENT=1
else
OPENTHREAD_ENABLE_EST_CLIENT=0
fi
AC_SUBST(OPENTHREAD_ENABLE_EST_CLIENT)
AM_CONDITIONAL([OPENTHREAD_ENABLE_EST_CLIENT], [test "${enable_est_client}" = "yes"])
AC_DEFINE_UNQUOTED([OPENTHREAD_ENABLE_EST_CLIENT],[${OPENTHREAD_ENABLE_EST_CLIENT}],[Define to 1 if you want to enable EST Client])
OpenThread DNS Client support : ${enable_dns_client}
// my code begin
OpenThread EST Client support : ${enable_est_client}
// my code end
OpenThread SNTP Client support : ${enable_sntp_client}
I've also edited the makefile:
openthread/src/core/Makefile.am
crypto/ecdsa.hpp \
crypto/ecp.hpp \
crypto/hmac_sha256.hpp \
crypto/ecdsa.cpp \
crypto/ecp.cpp \
crypto/hmac_sha256.cpp \
My build command is "make -f examples/Makefile-nrf52840 EST_CLIENT=1".
I think once this problem is solved, i can solve the others by myself as the root of the problem seems to be the same.
Thanks.
You have an error during the link, the symbol mbedtls_pk_write_pubkey_pem is not defined, that means you missed to specify the lib defining it. Looking on the web it seems you need to link with mbedcrypto, so add libmbedcrypto.a or -lmbedcrypto (and may be use the option -L to specify the path)
It seems you also use X509, if you have missing symbols *X509* link with mbedx509, so add libmbedx509.a or -lmbedx509 (and may be use the option -L to specify the path)
I am trying to create a student response system for a Jeopardy-like game using cheap tv remote controls. They are infrared, NEC protocol. A serial monitor displays button press from students in order they respond.
I'm using a TSOP 4838 receiver connected to an Arduino Uno with a capacitor and so far just the serial monitor that comes with the Arduino IDE software. My code appears below.
All is working well as long as 2 or more students do not press buttons within a half-second of each other. If that happens, I get no output on the serial monitor. I'm hoping there is some change I can make to my sketch or to the IRremote.h or IRremoteInt.h files to discern the signals quicker so my display lists who clicked first.

In short - Not really and not reliably. The problem is that your system is effectively multi-dropped. The receiver is the seeing the sum of both transmitters. Where the modulation and encoded signal are summed up and thus corrupted.
I have IR toy magic wands, for dueling I have a the winner keep transmitting as to JAM the looser latter signal.
You could try to use TWO different modulation frequencies. One remote at 36K and the other at 60K. 38K is typical and there is significant overlap. I have seen 36 and 40 get heard or corrupt 38K. So I would got to the farthest ends of available demodulator chips; being 36K and 60K. However, I suspect you are using provided transmitters which may not be changed. So you will have to find some or build one.
Additionally using pre-built ones, you are at the mercy of its behavior. You stated 1/2 second. That is likely because they are re-transmitting retries and have start delays and pauses beyond that of the NEC frame being sent.
You could also implement RX/TX pairs that are different IR wavelength. However, most purchasable demodulator IC's are on standard wavelength. I also recommend not building a discrete RX when possible, as they integrated RX/Demodulators have Auto GAIN, stuff like that.
I would like to be able to switch my feed between an image, a video and a webcam.
Atm i try this:
#define F_WEBCAM
#define F_VIDEO
#define F_IMAGE
#define FEED(F_WEBCAM)
Somewhere else:
#if defined(FEED) && FEED == F_WEBCAM
ofVideoGrabber vidGrabber;
#elif defined(FEED) && FEED == F_VIDEO
ofVideoPlayer vidPlayer;
#elif defined(FEED) && FEED == F_IMAGE
// code for image
#endif
But i get the following error:
Expected value in expression
Is this possible the way i want?
To compare, you need to define your macro constants with values. This will solve your issue:
#define F_WEBCAM 1
#define F_VIDEO 2
#define F_IMAGE 3
#define FEED F_WEBCAM
I am fairly new to C++ programming, so please bear with me. I am writing a small application in visual studio that would be used to communicate with an FTDI module (UM232H high speed USB module). FTDI provides the D2XX drivers for this module and is readily available on their website. Right now the program I have is very simple. It is calling a function called FT_Open (ftd2xx.h) to simply open the device and top check to see if the device is connected to the computer.
However right now I keep getting the error LNK2019, unresolved external symbol. Now I did read through the application note provide by Visual Studio website but I still can not seem to resolve my error. I think I am making a silly mistake and would like some guidance from you guys, if you guys could help me out.
I have provide my code as well as the header file (ftd2xx.h) that was provide from the FTDI website.
Main Program:
// ConsoleApplication2.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include "ftd2xx.h"
#include <iostream>
using namespace std;
FT_HANDLE ftHandle;
FT_STATUS ftStatus;
int main(){
ftStatus = FT_Open(0,&ftHandle);
if (ftStatus == FT_OK) {
cout << "hello world";
// FT_Open OK, use ftHandle to access device
}
else {
// FT_Open failed
}
return 0;
}

--Rest of the of the header file was omitted because of the limit to the number of characters I could write.
Sorry for the large amount of code I provided here, I just wanted to be sure that I provided everything that I possibly could. Let me know if I would need to provide the rest of the header file.
Maybe it is bit later for an answer.
I got same error with old outdated ftd2xx.lib file.
Afetr adding new ftd2xx.lib, ftd2xx.dll and ftd2xx.h files, cleaning and rebuilding the project a problem was solved.
Have you made sure to include the .lib your compiler will need to link against? Along with any header files, they probably provided a .lib and/or .dll.
If you use the static version of the .lib, you will have to define FTD2XX_STATIC to the preprocessor, as explained in the documentation (chapter 2.4 of Instructions on Including the D2XX
Driver in a VS Express Project).
Is there a way to escape macro names (identifiers) in a c pre processor (cpp) ?
I want to conditionalize some web code (html, css...) with readable macro names.
Example for a conditional css file:
/*root*/
some rootcode
#if height==480
/* height 480 */
.page {
line-height:23px;
}
#elif height<480
/* height < 480 */
.page {
line-height:46px;
}
#endif
An invocation of
cpp -P -D height=480 -oout.css css.ccss
results in (after deleting newlines)
some rootcode
.page {
line-480:23px;
}
but "line-480" is wrong.
Is there a way to escape "height" in the code without changing the macro name or stringify it?
You can either:
1) undefine the macro:
#undef height
2) rename the macro using standard-like caps:
#define HEIGHT
3) Use guards before processing the file:
#if height==480
#define HEIGHT_480
#undef height
#endif
#if height>480
#define HEIGHT_OVER_480
#undef height
#endif
/*root*/
some rootcode
#if HEIGHT_480
/* height 480 */
.page {
line-height:23px;
}
#elif HEIGHT_OVER_480
/* height < 480 */
.page {
line-height:46px;
}
#endif
The first one loses information after the undefine. The second one is impractical if there's extensive use of the macro.
The third one is the best option IMO. I've seen it used in production code where stuff like this was necessary.
I played with the idea of Luchian Grigore to undefine used filenames and I found a (nearly) general solution for this problem:
including a "define.file" at the begin of the conditionals and a "undefine.file" after the given condition.
So the problem is reduced to two macro names, that have to stay: DEFINEFILE und UNDEFINEFILE. But this two macros could be encrypted with their hashcode or with a randomname to avoid a use of this names in the conditional text.
The "define.file":
#define height 480
#define os 1
The "undefine.file"
#undef height
#undef os
the "conditionalcss.ccss"
/*root*/
some rootcode
#include __DEFINEFILENAMEPATH__
#if height==480
#include __UNDEFINEFILENAMEPATH__
/* height 480 */
.page {
line-height:23px;
}
#include __DEFINEFILENAMEPATH__
#elif height<480
#include __UNDEFINEFILENAMEPATH__
/* height > 480 */
.page {
line-height:46px;
}
#include __DEFINEFILENAMEPATH__
#endif
#if os==1
#include __UNDEFINEFILENAMEPATH__
os is windows (if 1 refers to windows)
and height also undefined i hope
#endif
Finally the cppcall with the parametric define and undefine files:
cpp -P -D __DEFINEFILENAMEPATH__="\"define.file\"" -D __UNDEFINEFILENAMEPATH__="\"undefine.file\"" -oout.css css.ccss
With this idea, the restulting "out.css" looks like:
some rootcode
.page {
line-height:23px;
}
os is windows (if 1 refers to windows)
and height also undefined i hope
This solution has only the disadvantages of two macros and a possible poor performace because of the multiple imports.
I hope it helps other people to solve their problem.
