cmake and Code::Blocks

cmake and Code::Blocks

[Pavel Fedin]

 Hello!

 I am working on a CMake-based project and building it under Cygwin. I decided to use Code::Blocks IDE since CMake already hass
appropriate project generator (i'm using "CodeBlocks - Unix Makefiles"). However, i had to manually edit the resulting .cbp file and
replace all paths with their native Windows equivalents; otherwise the IDE can't find any file and do anything.
 Is this a known TODO area for CMake or am i missing some magic switch while loading the project into CB ?

Kind regards,

Are both CMake and Code::Blocks Cygwin programs? I suspect you tried
to use a .cbp generated by Cygwin's CMake (which uses POSIX style
paths) with a non-Cygwin Code::Blocks. This is likely to be tricky.

 Of course not. Code::Blocks isn't Cygwin application, it's a native Windows application: http://codeblocks.org/
 BTW it has built-in support for Cygwin, it correctly recognizes the toolchain, at least gcc.

If you are trying to use a Windows based tool with Cygwin utilities, you are
likely to be the first, and on your own.

What evidence do you have of features that support Cygwin? Maybe CB doesn't
support Cygwin tools, or not very well, or maybe you have to change the
configuration, or provide the conversion, or maybe it's just not a good IDE for
those tools?

Having to edit file paths used by a tool is never a good sign. There are
probably a lot of other paths you may have to edit. Sometime the trick is to add
a couple of your own scripts to convert the paths in files to and from Cygwin
and Windows: hint - cygpath.

How would anyone here know if you are missing some magic switch using the tool
you chose?

Read and understand the docs to know the limitations and interface requirements
of the tools you have chosen.
Sometimes we make bad choices, have to scrap what we did, make hopefully better
choices, and restart from earlier.
Source control allows you to handle that more easily.

 In the project configuration i can choose "Cygwin toolchain", and it correctly detects c:/Cygwin as installation root.

 Well, this is too philosophical IMHO and is outside of question's scope.
 My takeout from your reply so far:
 1. No, there is no special support in CMake and there will never be one because mixing native Windows tools and Cygwin tools is not supported by Cygwin project
 2. You don't know whether Code::Blocks has any special support for Cygwin paths.

 Thank you very much for your time, i'll try to raise this in CMake development community and/or Code::Blocks development community. This issue could be solved on both sides.
