Re: Compile error for base R7.0.8.1

[Simon Rose via Tech-talk <tech-talk@aps.anl.gov>]

Hi Jörn - 

This has been fixed in 7.0.9, and is due to compilers being more strict. See https://urldefense.us/v3/__https://github.com/epics-base/epics-base/pull/579__;!!G_uCfscf7eWS!euJNE8WLfaZXPJPbnXykF2IsBmSmuriQVpmBtPNraFRRebwbeIqja1GMPJUH3dDtuYN0CqBM9blQkKXrvIxVnVM1$ 

Cheers,

Simon

Hello,


today I ran into a bug in EPICS base R7.0.8.1 while testing e3.


It fails to build in modules/libcom/cxxTemplates:


In file included from ../cxxTemplates/resourceLib.h:43,
from ../cxxTemplates/resourceLib.cpp:15:
../cxxTemplates/tsSLList.h: In member function ‘bool tsSLIterConst<T>::operator==(const tsSLIterConst<T>&) const’:
../cxxTemplates/tsSLList.h:314:32: error: ‘const class tsSLIterConst<T>’ has no member named ‘pConstEntry’ [-Wtemplate-body]
314 | return this->pEntry == rhs.pConstEntry;
| ^~~~~~~~~~~
../cxxTemplates/tsSLList.h: In member function ‘bool tsSLIterConst<T>::operator!=(const tsSLIterConst<T>&) const’:
../cxxTemplates/tsSLList.h:320:32: error: ‘const class tsSLIterConst<T>’ has no member named ‘pConstEntry’ [-Wtemplate-body]
320 | return this->pEntry != rhs.pConstEntry;


Looking at the definition of tsSLIterConst one finds an pEntry member which is used at those positions in R7.0.9 but not in R7.0.8.
How to fix that?
