Hello, I have already built successfully a working cross-compiler for several machines: i686-w64-mingw32 and avr. Now, I would like to build a cross-compiler for a Raspberry Pi. The programs I am using are: - binutils-2.26 - gcc-5.3.0 I start by building binutils for my target machine: --- $ ./configure --prefix=/usr --target=arm-unknown-linux-gnueabi --disable-nls $ make --- As you can see, I am using the "arm-unknown-linux-gnueabi" machine name. I don't know exactly how we determine the correct machine name. I have done a first try with "arm-linux-gnu" then I got an error later while building gcc: --- $ ../gcc-5.3.0/configure --prefix=/usr --target=arm-linux-gnu --enable-languages=c --disable-nls --disable-multilib --disable-threads --disable-shared $ make [...] checking if mkdir takes one argument... no *** Configuration arm-unknown-linux-gnu not supported make[1]: *** [configure-gcc] Error 1 make[1]: Leaving directory `/tmp/build/arm-unknown-linux-gnueabi/gcc-5.3.0-tmp' make: *** [all] Error 2 --- But as I have read some web pages [1, 2, 3] where "arm-unknown-linux-gnueabi" is the machine name, I have used this machine name. With this new machine name, the error above disappears. It seems that the machine name matters while building the cross-compiler and I can't use any value for that. After building binutils successfully, I continue by building gcc for my target machine: $ ../gcc-5.3.0/configure --prefix=/usr --target=arm-unknown-linux-gnueabi --enable-languages=c,c++ --disable-nls --disable-multilib --disable-threads --disable-shared $ make [...] checking dynamic linker characteristics... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES. make[1]: *** [configure-target-libssp] Error 1 make[1]: Leaving directory `/tmp/build/arm-unknown-linux-gnueabi/gcc-5.3.0-tmp' make: *** [all] Error 2 The error above means that glibc is missing (at least that's what I read in [4]). So, I need to cross-compile glibc. But for doing that, I have to build a minimal cross-compiler first. I probably need to disable other things in order to build the cross-compiler without glibc. My questions: 1) How we determine the correct machine name? 2) How to build my cross-compiler without glibc? Thank you. Best regards.
