Re: Why not contribute? (to GCC)
Like many people it seems I've read the gcc lists for many years but never contributed. I am an embedded developer using GCC on x86 and ARM. - GCC works really well, i've never found a serious GCC bug so there is nothing that i have had to fix. No "itch to scratch". - When i modified GCC for C++ support on a propitiatory RTOS (Nucleus), it was a bit of a bodge so i knew it would not get accepted, but it works well enough for me. - I have reported bugs mostly to do with cross compiling but the proper fix is often more complex than my 5 minute hack to build the cross compiler, you generally only build these things once so its a lot of effort for a small gain. - Matthew J Fletcher
template class scoping rules
Hi
This cut down example does not compile with gcc 3.4.x / 4.0.x or 4.1.0.
test.cpp: In constructor 'Three::Three()':
test.cpp:20: error: 'm_Public' was not declared in this scope
It does compile with VS2005 / VS6
class One
{
public:
One();
~One();
public:
int m_Public;
};
template class Two : public One
{
public:
Two() {m_Public = 0;}
};
template class Three : public Two
{
public:
Three() {m_Public = 0;}
};
this fixes it.
template class Three : public Two
{
public:
Three() {Two::m_Public = 0;}
};
any ideas ?
regards

gcc #pragma pack(push[,n]) target spesific ?
Hi on my i486-unknown-elf target i am unable to use #pragma pack(push[,n]) / #pragma pop(n), which happen to be the same as Microsofts #pragma syntax. this is because HANDLE_PRAGMA_PACK_PUSH_POP is only defined for linux/i386/alpha/sparc freebsd and others. Is this correct ?, comments in the appropreate config.h files indicate that HANDLE_PRAGMA_PACK_PUSH_POP, is mostly used for wine compatablity, but is there any reason why HANDLE_PRAGMA_PACK_PUSH_POP is not present on all targets ? also there is not a configure option. i note that in gcc4 only djgpp and cygming targets have HANDLE_PRAGMA_PACK_PUSH_POP defined, also the gcc4 documentation does not say these #pragmas are target spesific. regards --- Matthew J Fletcher Embedded Software Serck Controls Ltd --- ** Serck Controls Ltd, Rowley Drive, Coventry, CV3 4FH, UK Tel: +44 (0) 24 7630 5050 Fax: +44 (0) 24 7630 2437 Web: www.serck-controls.com Admin: [EMAIL PROTECTED] A subsidiary of Serck Controls Pty.
