RE: Building 3.14.7 on win32-x86 with Visual C++ 6.0

Hello Jinhyuk Choi ,

 

Of course the root cause of inconvience is that we are using different versions

of visual visual C++. For example, I am using visual studio.NET 2003 which has

better compliance with ANSI C++ standards compared to visual C++ 6.0.

 

One of the changes proposed would actually prevent the code from compiling with a

standards compliant compiler. For example with recent versions of GNU g++ the

following result occurs.

 

    for (unsigned i=0; i<10; i++);
    for (i=0; i<10; i++);

 

/cygdrive/d/users/hill/epicsDvl/epics/base$ g++ tmp.cpp
tmp.cpp: In function `int main()':
tmp.cpp:5: error: name lookup of `i' changed for new ISO `for' scoping
tmp.cpp:4: error:   using obsolete binding at `i'

 

Nevertheless, I have committed changes to CVS for R3.14.8

(availalable soon for testing via a nightly snbapshot) that should

hopefully allow visual studio 6.0 to be used also.

These command line switches, available only with the more recent compiler,

do generate warnings if used with the older compiler.

 

One possible way to avoid the warnings would be to create a set of

config files for host architecture win32-x86-MSVS6.0

No doubt that they will.

 

Thanks very much for your assistance.

Subject: Building 3.14.7 on win32-x86 with Visual C++ 6.0

Hi all,

I'm a beginner in EPICS.
With some experience with Visual C++6,
I've built 3.14.7 on win32-x86 correcting some errors.
The errors fixed are as follows.

1. base/src/libCom/osi/epicsThread.cpp
std::unexpected () -> unexpected ()
visual C get unexpected() out of std namespace.

2. base/src/ca/udpiiu.cpp
line 244: remove unsigned in "unsigned i"
duplicated definition

3. base/src/ca/tcpiiu.cpp
line 1982: remove return in "return nettiu::uninstallChannel...()
void should not return something

4. base/src/gdd/dbMapper.cc
line 1108 & 1134: remove int in "int i"
duplicated definition

I've finished building with some warnings:

1. No /GL, /w44355 options for cl
2. No /LTCG option for link

Please forgive me if someone has already addressed the above points.
For the warnings, I should study further and any help will be appreciated.

Still it should be checked if it works fine.

I wish this list can help to someone.
