[TridentTD]

I have already donwloaded gcc-xtensa version 4.9.2 release version.
and I have already install MingW on my computer.

If I want to build for Windows platform , how to build them ?

Thank you.

Please consider using prebuilt toolchain for Windows, like this one, or this one. It will save you a lot of trouble if all you need is the toolchain.

If you decide to build gcc yourself the easiest way is to use somebody's else build scripts, e.g.: CHERTS, Fabien Poussin.

In general, it's just building a cross-compiler, a huge topic covered by the gcc documentation.

Thank you very much.

// Sorry for my poor English.

I have just tried both shell-script, however when call the scripts ,
both (CHERTS's shell-script & Fabien Poussin's shell-script) can't find ../configure
occur error like this.

.......
Buidling GMP
./build.sh: line 103: ../configure: No such file or directory

How can I find the configure file?

How can I find the configure file?

Debug what the script does.

• check if the configure file is actually there (it should be in the ./dl/gmp-6.0.0a, if not there run the script with -x to see the trace of what it does to understand what went wrong).
• check if the configure script is executable (ls -l ./dl/gmp-6.0.0a/configure should show 'x' in permissions. If it doesn't then I guess it has something to do with tar or your filesystem. You can do chmod +x to make it executable, but I guess the same issue will happen with other scripts and compiled programs.
• check that you have script interpreter available (/bin/sh for that particular configure), if not install it or make a symbolic link.

And don't worry, your English is fine.
