CMake fails to use a toolchain to cross-compile

[Eduardo Sánchez Muñoz]

I get the following error when I use a toolchain file to cross-compile with mingw32:

$ cmake -DCMAKE_TOOLCHAIN_FILE=~/Documentos/mingw32.cmake -DCMAKE_INSTALL_PREFIX=/usr/i486-mingw32 .

I have just installed cmake 2.8.7 on ubuntu 11.10 amd64 via a build from source. I am having exactly the same issue. When I ran "make test"  there were 4 failures as follows:

25:FindPackageTest
73:Simple_EclipseGenerator
74:Simple_CodeBlocksGenerator
75:Simple_KDevelop3Generator

I ran "cmake ." from the FindPackageTest directory and got:

Package EnvB should have been [EnvB_DIR-NOTFOUND] but was
  [/home/MYHOME/cmake-2.8.7/Tests/FindPackageTest/lib/zot-3.1]

This was done today.

Martin.

you lack the definition of CMAKE_RC_COMPILER
which for your case should be something like:

SET(CMAKE_RC_COMPILER i486-mingw32-windres)

The attached toolchain file may be easier to tailor to you need on several host,
just comment/set the appropriate value for "COMPILER_PREFIX"
and USER_ROOT_PATH.

Thanks very much for the quick reply. I was under the seemingly mistaken
impression that the CMakeRCInformation.cmake module should automatically take
care of this. I will try your toolchain file with the suggested ammendments.

Cheers,  Martin.
