qmake not executable on buildplatform because it is compiled for the target :(

Hello,

I try to crosscompile qtcore or qt-embedded for stlinux (sh4-g++).
Now the configure- or buildprocess always fails with the errormessage ".../qmake: canot execute binary" because qmake wasalready compiled with the sh4-gcc crosscompiler and should be used on the x86 build platform.

Build Qt for your desktop then as well and use its qmake to generate makefiles for the other platform.

Hello Wysota,

I already thougt about this, but I canot imagine that this is the only possibility and canot be the intention of an automatic configuration for a crosscompilation. :(

I don't really understand... That's a standard procedure with every cross compilation - you need tools that are built for the platform you are compiling on. It's like if you said this is a problem because you have to have the crosscompiler instead of having a single compiler building for all possible platforms and on all possible platforms.

Hello wysota,

probably you are right, I am new to crosscompilation or at least to crosscompilation where you have to build your own tools before I only used Crosscompilers where the complete toolchain cam from the CVS.
I alredy noticed the fact that here alsosome tools have to be build for the system I compile on, I was only starteled that this is not both part of one configure- or makeprocess and that the binaries for the different platforms are not kept apart in differen directories like /bin/host and /bin/trget.

thank you for your help

Did it come as sources or as binary? If the former, then that's the exact same situation - you need to build a tool from sources for the correct platform. The difference might be that tools you used were meant for a single platform. In case of Qt and friends the same set of sources is meant to work on all platforms.
