I'm trying to create a cross-platform C++ development environment, that
needs to work on Linux, MacOS and Windows. I'm considering using Eclipse
C++, after all, it's cross-patform as it is.
But I'm having problems re-using Eclipse projects created among the
platforms. For one, they actually contain a specific reference to the
toolchain used (like Linux GCC - that won't work MacOS or Windows, and
vice versa). Also, on different platform one needs different compiler and
linker options as well.
Of course, one could just create an Eclipse project for each target
platform, but then a lot of stuff has to be duplicated, like when adding
new files, libraries, all of them have to be updated manually.
Is there a solution to the above issue?
Thanks,
Akos

Hi,
to use the same project on different platforms, I find it most
convenient to set platform dependent settings as global (-> workspace)
settings.
If for example, I want to set include and library paths for libraries
that are installed on the system, I open the "Window / Preferences"
dialog and set CPATH and LIBRARY_PATH under "C/C++ / Environment" to
point to my boost/wxwidgets/openssl/whatever directories.
This won't solve all platform related problems, but saves a lot of
typing since you don't have to addjust these settings for each project.
Only the -l switches (which libraries to link) have to be specified on a
project basis -- well, if they're always the same, you could probably
set an environment variable for these as well (DEFAULT_LIBS="-lxyz -l
abc") and add that one to your toolchains link command...

Setting up your project as standard make is an alternative: cdt does not
distinguish toolchains for standard make.
Easiest way for standard make projects should be installing mingw, bash,
and make (in C:\bin\mingw32) and having this make.bat in your path:
@echo off
SET PATH=%PATH%;C:\bin\MinGW\bin
SET CPATH=C:\bin\boost_1_34_1\
bash -i -c "mingw32-make.exe %1 %3 %4 %5 %6 %7 %8"
For the default managed make, a per workspace toolchain setting and an
option "Use System default toolchain" in the project settings would be nice.
