OSDev.org :: View topic - GCC Cross-Compiler issue

If you plan to use GCC 4.3.0 or a later version, you will also have to install the following:
GMP (this package is also readily available for MSYS)
MPFR

Is that shared library in a directory where your loader is told to look at?

/etc/ld.so.conf (or ld-elf), LD_LIBRARY_PATH, man ldconfig. If the directory containing that library isn't in anywhere loader thinks it should be, try setting LD_LIBRARY_PATH and running it then. If it works, change your configuration.

Hi! I am very new to using GNU tools and doing os deving, so i apologize if the answer to this question is obvious! I have been following some simple os dev tutorials using DJGPP on Windows Vista, but earlier today i decided to install Ubuntu 9.10 (dual boot), and i wanted to make a working GCC Cross-Compiler for i386 target that i can use for os deving. I followed the tutorial at this link to compile a GCC Cross-compiler: http://wiki.osdev.org/GCC_Cross-Compiler ... and the AS asm from binutils seems to work, but GCC doesnt. When i try to compile anything with the gcc cross-compiler i get this error message: Code: /usr/cross/libexec/gcc/i386-elf/4.4.3/cc1: error while loading shared libraries: libgmp.so.10: cannot open shared object file: No such file or directory Btw I did not forget this before compiling gcc: (if it even has to do with this) Quote: If you plan to use GCC 4.3.0 or a later version, you will also have to install the following: GMP (this package is also readily available for MSYS) MPFR If I can't get this to work i will have to go back and do os dev on Windows. But linux seems much more intresting to me! So if anyone knows how to fix this it would be very nice! tobbebia
