Hi,
I've been trying to compile some code to use threads, but so far I've not
got past the compilation stage. Currently I have a class with lots of
member funtions and I wrote two extra member functions to try and run a
perl script in the background and pipe the output into a TGTextView.
These are my member functions:
void SurfMainFrame::fExternalTest(void){
char fReadLineText[1000];
FILE* in = gSystem->OpenPipe("./run.sh", "r");
while (!feof(in)){
fgets(fReadLineText, 1000, in);
printf(fReadLineText);
fScaleTextView->AddLine(fReadLineText);
}
fclose(in);
}
void SurfMainFrame::fThreadTest(void){
fEthread = new TThread("Ethread", SurfMainFrame::fExternalTest);
fEthread->Run();
}
And from the header file:
public:
void fExternalTest(void);
void fThreadTest(void);
private:
TThread *fEthread;
but when I compile the compilation stops at the line:
fEthread = new TThread("Ethread", SurfMainFrame::fExternalTest);
from above:
SurfMainFrame.cxx: In method `void SurfMainFrame::fThreadTest ()':
SurfMainFrame.cxx:307: assuming & on `SurfMainFrame::fExternalTest'
SurfMainFrame.cxx:307: no matching function for call to
`TThread::TThread (const char[8], void (SurfMainFrame::*) ())'
/usr/local/cern/root/include/TThread.h:109: candidates are:
TThread::TThread (void *(*) (void *), void
* = 0, TThread::EPriority = kNormalPriority)
/usr/local/cern/root/include/TThread.h:110:
TThread::TThread (void (*) (void *), void *
= 0, TThread::EPriority = kNormalPriority)
/usr/local/cern/root/include/TThread.h:111:
TThread::TThread (int = 0)
/usr/local/cern/root/include/TThread.h:112:
TThread::TThread (const char *, void *(*)
(void *), void * = 0, TThread::EPriority = kNormalPriority)
/usr/local/cern/root/include/TThread.h:113:
TThread::TThread (const char *, void (*)
(void *), void * = 0, TThread::EPriority = kNormalPriority)
/usr/local/cern/root/include/TThread.h:177:
TThread::TThread (const TThread &)
make: *** [SurfMainFrame.o] Error 1
I've looked ad I've tried everything I can think of to get this working,
but somehing is eluding me. Anyone have some hints for me?
Without these member functions, my code compiles and runs fine, so it's
these additions causing me problems.
