Ice Php 1.0.2 link error

fengxb

Hi,

I downloaded the new release of ICE and IcePhp. After succeeded in compiling the ICE, I Failed to compile the IcePhp. The compiler is MSVC6.0.

The link errors lare isted:

maybe it's wrong STL version?

recommend you rebuild full Ice by youself, because Ice Use stl, maybe your version of stl is not equal to Ice's stl verion.

on windows, VC 7.1 is better choice, because the stl is compatibile stl standards, but vc 6 's stl is garbage.

damingyipai

multiple stl implement?

seem like your stl is stlport? the stlport include directory must be first in path list.

fengxb

Thanks for your reply.

I have compiled ICE 1.3 with correct STLPort 4.5.3.

damingyipai

maybe need to rebuild all, if not do this.

.

fengxb

Which version STL Port did you use to compile?

damingyipai

on windows, I use Visual C++.NET 2003

it still works well.

damingyipai

if you use VC++ 2003 to build Ice,

you need not stlport. because stl in VC++ 2003 is followed standard .

fengxb

Thank you.

After I download and compile the new release of STLPort, the number of link errors have reduced to 11.

The linker always told me redefinition of some STL struct. The errors is followed:

I am confused that I succeeded in compiling ICE1.3 than failed to compile IcePHP 1.0.2. Faint!

BTW, my compiler is MSVC6.0.

Any replies are appreciated.

Hi,

We're getting the same link errors, and we're looking into it.

We honestly didn't expect that many users would be interested in compiling the Ice extension themselves, but would rather prefer to download the precompiled version. This version was compiled with VC7.0 and would require that you install the corresponding VC7.0 Ice binaries, so I realize that could cause some difficulties for you if you also want to use Ice with VC6.

We'll let you know what we find out.

Take care,
- Mark

To fix the link errors, edit the file IcePHP-1.0.2/src/ice/ice_common.h and add the line indicated below:

#include <Ice/Ice.h>
#include <Slice/Parser.h>  // ADD THIS LINE

I'm still not sure why this is necessary, but I suspect a compiler bug since it compiles fine in VC 7.0 without this change.

This fix will be included in the next release.

Take care,
- Mark

Thank you, mes.

I edited the source code as your suggest. But there is a link error followed by.

I edit the Profile.cpp. I search all senteces include "find" and replace inverted comma with double quotation marks. It links successful. I hope it would work fine.

Thanks,
