问题
I'd like to use Eclipse IDE for C++ dev but these is one little prob.
First, a little boiler plate:
- mingw 64bit C++ compiler (Custom compilation A)
- mingw 64bit C++ compiler (Custom compilation B)
- windows host
The problem
I can not get it to work with multiple toolchains. All info I could find suggested that eclipse requires mingw dir to be at C:\mingw\
that does not work for my use case. For one, I have multiple custom compiled mingw compiler tools. I can at most put one at C:\mingw\ (Obviously).
This implies to me that Eclipse does not support multiple custom toolchains for C++.
If this is not the case, please explain how one can hook up Eclipse to use multiple compilation toolchains.
To keep thing simple let's make some base assumptions:
Location of goodies:
D:\mingw_cust1\mingw\
D:\mingw_cust2\mingw\
When I make a new project in eclipse I'd like to be able to choose which toolchain I want for that project.
回答1:
The question is old & maybe obvious but I spent time trying to answer it for myself.
The easiest way to switch MinGW path in a project is probably to change the MINGW_HOME variable.
To change it : Project > Properties > C/C++ Build > Environment > MINGW_HOME field
Once changed the origin of MINGW_HOME is "USER: CONFIG" instead of "BUILD SYSTEM" and therefore the parameter is project-specific (or even configuration-specific)
In my case I could set "D:\mingw_cust2\mingw\" (2) instead of "D:\mingw_cust1\mingw\" (1) inherited from the os 'PATH' where it was above the (2)
One could also set the toolchain for the whole workspace (and have a workspace per toolchain) by setting the MINGW_HOME variable in Window > Preferences > C/C++ > Build > Environment
