@mrjj still not able to compile; with the same error of undefined reference to SAMPLE_VDEC_VdhH264() in main.cpp. and ld returned 1 exit status.
I removed the function declaration in main.cpp and directly invoke the function inside pushButton function as you've mentioned.
In main.cpp, highlighting the invoked function " SAMPLE_VDEC_VdhH264();" and hitting [F2] on the keyboard brings me to the header where this function is declared. However with repeated [F2] trigger, it does not seems to be linked to my function definition as defined in my sample C file which I've added.
in main.cpp#include "mainwindow.h"
#include "ui_mainwindow.h"
#include "hi3536mainfx.h"
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
}
MainWindow::~MainWindow()
{
delete ui;
}
void MainWindow::on_pushButton_clicked()
{
SAMPLE_VDEC_VdhH264();
}
In sample C file where SAMPLE_VDEC_VdhH264() is defined:HI_S32 SAMPLE_VDEC_VdhH264(HI_VOID)
{
VB_CONF_S stVbConf, stModVbConf;
HI_S32 i, s32Ret = HI_SUCCESS;
VDEC_CHN_ATTR_S stVdecChnAttr[VDEC_MAX_CHN_NUM];
VdecThreadParam stVdecSend[VDEC_MAX_CHN_NUM];
VPSS_GRP_ATTR_S stVpssGrpAttr[VDEC_MAX_CHN_NUM];
