Re: [Plplot-devel] Distinction between 32-bits and 64-bits libraries

Hi Phil,



I should perhaps have added that I had to get around a somewhat similar problem with a directory containing an installation of GTK – how CMake determined that it is there, I have no clue, but the directory is



d:\nag\efbuilder 6.1\gtk



which is nowhere near the directories normally searched by CMake as far as I know. By renaming that directory I solved the problem that CMake included directories like “6.1\gtk\include” in the build procedure.



Regards,



Arjen

Hi Phil,



Yes, life is much easier if you can stick to just one bit size. I try to be consistent and install only 64 bits stuff, but in this case I reverted to the 32-bits version of the compiler to see if the linkage problem was caused by using 64 bits rather than 32 bits. The problem I described made that diagnostic null and void. But I realised that this may be a more general problem.

Arjen

Hi Arjen
I see the same problem. 64 bit windows, 64 bit tcl, linking fails in visual studio for 32 bit builds.

This is the only library I see this problem with, but I think I built all other dependencies myself, whereas I installed tcl with its installer.

My solution is that I have just stopped doing 32 bit builds, but I appreciate there are still a few 32 bit windows installs around that you may need to compile for. For a while I persisted with a separate 32 bit cmake call, which I needed to do anyway to pull in the correct wxWidgets library. I just disabled tcl in that build.

Hello,



Yesterday, while trying to solve an issue with the Tcl binding under bare Windows, I came across the following problem:

-        I have a 64-bits Tcl version installed

-        I use the 32-bits compiler environment (MS Visual Studio, set for 32 bits)

-        CMake finds the Tcl libraries and arranges for the Tcl bindings to be built

-        The build subsequently fails because the import library that is used (64-bits) is not suitable for the compilation and linking (32-bits)



I presume similar things may happen with other external dependencies that come in different varieties. Should we guard against this happening or not? I have no idea how difficult it is to implement that.



For now, I suggest we warn about the possibility of this confusion in the documentation.



Regards,



Arjen
