PJSUA Makefile error: Invalid use of non-static data member 'param' - c++

Working with pjsua and the pjsua-jni folder I have run into a error. Being new to C and C++ I have just learning as I go. I have experience with programming so I am not that out of my league, I hope.
The errors I get from the make file is

I am not sure how to declare this param. When looking in the codecs.h file I find this
typedef struct pjmedia_codec_fmtp
{
pj_uint8_t cnt; /**< Number of parameters. */
struct param {
pj_str_t name; /**< Parameter name. */
pj_str_t val; /**< Parameter value. */
} param [PJMEDIA_CODEC_MAX_FMTP_CNT]; /**< The parameters. */
} pjmedia_codec_fmtp;
So the way its calling the param struct is pjmedia_codec_fmtp::param *arg2. Is that right? I know that the :: usually is how you call a static method but is that how you call structs too?
Anyway help would be great
This is the code it throws the first error on
pjmedia_codec_fmtp *arg1 = (pjmedia_codec_fmtp *) 0 ;
pjmedia_codec_fmtp::param *arg2; // Error

Getting syntax error in GLSL array constructor not supported

with this code
var mat_add = gpu.createKernel(function(A, B) {
var sum = [];
for (var i=0; i<3; i++) {
sum.push(A[this.thread.y][i] + B[i][this.thread.x]);
}
return sum;
}).dimensions([2, 2]);
I am getting this error:
An error occurred compiling the shaders: ERROR: 0:141: '' : array size must be greater than zero
ERROR: 0:141: '[]' : array constructor supported in GLSL ES 3.00 and above only
ERROR: 0:141: 'constructor' : array constructor needs one argument per array element
ERROR: 0:141: '=' : Invalid operation for arrays

ERROR: 0:145: 'sum' : undeclared identifier
ERROR: 0:145: '' : methods supported in GLSL ES 3.00 and above only
ERROR: 0:145: 'push' : invalid method
This actually works:
var mat_mult = gpu.createKernel(function(A, B) {
var sum = 0;
for (var i=0; i<3; i++) {
sum += A[this.thread.y][i] * B[i][this.thread.x];
}
return sum;
}).dimensions([2, 1]);
Does anyone know how to fix this syntax error?
Thanks

Well it has been four years but hopefully this helps someone. For some reason you are not able to create a vector object containing a native list of objects (maybe someone could explain why?).
So, for example, when creating a 18x2 vector containing 1'ns for example:
std::vector<double[2]> my_vector(18, {1.0, 1.0});
So instead you should to the following:
std::vector<vector<double>> my_vector(18, vector<double>(2,{1.0, 1.0});

In C++11, a std::array can be used:
std::vector<std::array<double,2>> my_vector(18, std::array<double,2>{1.0, 1.0});

Resolve c++ pointer-to-member error in VS 2003

I have a c++ program that I'm trying to port from VS98 to VS2003 (incremental steps). One error that occurs throughout is "Error 2275"
For instance: k:\RR\chart\chartdlg.cpp(2025): error C2475: 'CRrDoc::cFldFilter' : forming a pointer-to-member requires explicit use of the address-of operator ('&') and a qualified name
The offending code is shown below:
void CDataPage::OnBtnLabelField()
{
FLDID fid ;
LPMFFIELD f ;
CRrApp *pApp = (CRrApp *)AfxGetApp();
CMainFrame *pFrame = (CMainFrame *)AfxGetMainWnd();
CRrDoc *pDoc = (CRrDoc *)pFrame->GetActiveDocument();
CSelectFieldDlg dlg;
//**************************************************
//BOOL CRrDoc::*zcFldFilter = &CRrDoc::cFldFilter;
//dlg.ck = CRrDoc->*zcFldFilter;
//**************************************************
dlg.ck = pDoc->cFldFilter ;
dlg.TitleTextID = IDS_2676;
fid = (FLDID)dlg.DoModal();
if (fid != NOID)
{
f = pDoc->m_pComposite->mfbyndx(fid);
// find index
int i, iCount;
iCount = m_lboxLabel.GetCount();
for (i = 0; i < iCount; i++)
{
if(fid == m_lboxLabel.GetItemData(i))
{
m_lboxLabel.SetCurSel(i);
OnSelchangeComboLabel();
}
}
}
}
I tried handling it according to a Microsoft page: But that just generated a set of other problems (the commented code between the asterisks). Note that I also commented out the following line:
dlg.ck = pDoc->cFldFilter
Unfortunately, this leads to a new error: k:\RR\chart\chartdlg.cpp(2022): error C2440: 'initializing' : cannot convert from 'BOOL (__cdecl )(LPMFFIELD)' to 'BOOL CRrDoc:: '
The definition in the .H file looks like:
public:
static BOOL cFldFilter(LPMFFIELD f);
Any ideas how to handle the pointer-to-member issue?

since you have:
static BOOL CRrDoc::cFldFilter(LPMFFIELD f);
its type is not a member variable but a function:
//BOOL CRrDoc::*zcFldFilter = &CRrDoc::cFldFilter; // doesn't work
BOOL (*zcFldFilter)(LPMFFIELD) = &CRrDoc::cFldFilter; // works
Since dlg.ck is of a correct type, you should do
dlg.ck = &CRrDoc::cFldFilter;

easy petsc function call in a class

The following question might be easy to answer, but I did not find any solution in the Internet. To put it in a nutshell, I put some petsc function calls in a class.
The following equation solver script works without any problems:

}

According to CHKERRQ doc you need to use rather CHKERRV inside functions returning void or any other non-integer datatype.

I can only presume that your CHKERRQ macro expands to something like
if (ierr != 0) return ierr;
Which you could have determined by looking at the lines the compiler message worked out and then finding out what that macro did.
I don't think I dare comment on the style of this code. It just needs a serious rewrite. Taking C code and wrapping it with method calls in a class does not make it C++ code.

PETSc has provided another way to check error in function without return valus: CHKERRABORT(comm,n).
CHKERRABORT: Checks error code returned from PETSc function. If non-zero it aborts immediately.
As following said, CHKERRV will ignore error and is not recommend.
You can use CHKERRV() which returns without an error code (bad idea since the error is ignored) or CHKERRABORT(comm,n) to have MPI_Abort() returned immediately.

error with 2 lines : error C2663: 'std::_Tree<_Traits>::insert' : 4 overloads have no legal conversion for 'this' pointer
IntelliSense: no instance of overloaded function "std::set<_Kty, _Pr, _Alloc>::insert [with _Kty=IP *, _Pr=std::less<IP *>, _Alloc=std::allocator<IP *>]" matches the argument list and object (the object has type qualifiers that prevent a match)
please help me?

I had exact same error with std::set, while passing it to a lambda expression:
C2663 'std::_Tree<std::_Tset_traits<_Kty,_Pr,_Alloc,false>>::insert': 5 overloads have no legal conversion for 'this' pointer
lambda expression prototype was:
[se1, ele1](auto val) {
/* here I was editing se1 set, but above se1 is passed value type */
}
I have changed to:
[&se1, ele1](auto val) {
/* now since se1 set is sent as reference type above, it is good to edit
changes stays as I expect it to be
*/
}
Now compilation succeeds.
I used with count_if function, which calls the lamda expression for eac element, so the compiler knows that modifications should persist in set se1, which is perfectly logical.
If you desire to have the original set unchanged, then send a copy of it.
