Re: [Tinycc-devel] Crosscompiling

Have you consider that compiler searches its own header path and header files have environment switches.

 

Make it clear where “mexPrintf” is defined and why it is not effective.

I'd tried to compile tcc itself with build_cross="yes" and tried

If you love problems I know a lot of options that you can try. ;)

Otherwise

    ./configure --enabie-cross && make && make install
    cd win32/examples
    x86_64-win32-tcc -v hello_win.c

did work with 0.9.26.  And still should if it hasn't been broken.

Indeed, this works fine for hello_win.c

But the tcc crosscompiler said that mexprintf is undefined

$ tcc -v -I /usr/include/octave-3.8.1/octave/ -shared mexample.c -o mexample.mex
tcc version 0.9.26 (x86-64 Linux)
-> mexample.c
<- mexample.mex
$ x86_64-win32-tcc -v -I /usr/include/octave-3.8.1/octave/ -shared mexample.c -o mexample.mex
tcc version 0.9.26 (x86-64 Win64)
-> mexample.c
tcc: error: undefined symbol 'mexPrintf'
$ x86_64-win32-tcc -v -I ~/R2013a/extern/include/ -shared mexample.c -o mexample.mex
tcc version 0.9.26 (x86-64 Win64)
-> mexample.c
tcc: error: undefined symbol 'mexPrintf'

And ideas why this just work with native tcc but not with tcc crosscompiler?
